"In marine transportation we have two methods, one for freight and another for passengers. The old-fashioned deeply immersed ship has not changed radically from the steam and sailing vessels of the last century, except that electricity has superseded all other motive powers. Steamers gradually passed through the five hundred-, six hundred-, and seven hundred-foot-long class, with other dimensions in proportion, till their length exceeded one thousand feet. These were very fast ships, crossing the Atlantic in four and a half days, and were almost as steady as houses, in even the roughest weather.
"Ships at this period of their development had also passed through the twin and triple screw stage to the quadruple, all four together developing one hundred and forty thousand indicated horse-power, and being driven by steam. This, of course, involved sacrificing the best part of the ship to her engines, and a very heavy idle investment while in port. Storage batteries, with plates composed of lead or iron, constantly increasing in size, had reached a fair state of development by the close of the nineteenth century.
"During the second decade of the twentieth century the engineers decided to try the plan of running half of a transatlantic liner's screws by electricity generated by the engines for driving the others while the ship was in port, this having been a success already on a smaller scale. For a time this plan gave great satisfaction, since it diminished the amount of coal to be carried and the consequent change of displacement at sea, and enabled the ship to be worked with a smaller number of men. The batteries could also, of course, be distributed along the entire length, and placed where space was least valuable.
"The construction of such huge vessels called for much governmental river and harbour dredging, and a ship drawing thirty-five feet can now enter New York at any state of the tide. For ocean bars, the old system of taking the material out to sea and discharging it still survives, though a jet of water from force-pumps directed against the obstruction is also often employed with quick results. For river work we have discovered a better method. All the mud is run back, sometimes over a mile from the river bank, where it is used as a fertilizer, by means of wire railways strung from poles. These wire cables combine in themselves the functions of trolley wire and steel rail, and carry the suspended cars, which empty themselves and return around the loop for another load. Often the removed material entirely fills small, saucer-shaped valleys or low places, in which case it cannot wash back. This improvement has ended the necessity of building jetties.
"The next improvement in sea travelling was the 'marine spider.' As the name shows, this is built on the principle of an insect. It is well known that a body can be carried over the water much faster than through it. With this in mind, builders at first constructed light framework decks on large water-tight wheels or drums, having paddles on their circumferences to provide a hold on the water. These they caused to revolve by means of machinery on the deck, but soon found that the resistance offered to the barrel wheels themselves was too great. They therefore made them more like centipeds with large, bell-shaped feet, connected with a superstructural deck by ankle-jointed pipes, through which, when necessary, a pressure of air can be forced down upon the enclosed surface of water. Ordinarily, however, they go at great speed without this, the weight of the water displaced by the bell feet being as great as that resting upon them. Thus they swing along like a pacing horse, except that there are four rows of feet instead of two, each foot being taken out of the water as it is swung forward, the first and fourth and second and third rows being worked together. Although, on account of their size, which covers several acres, they can go in any water, they give the best results on Mediterraneans and lakes that are free from ocean rollers, and, under favourable conditions, make better speed than the nineteenth-century express trains, and, of course, going straight as the crow flies, and without stopping, they reach a destination in considerably shorter time.
"Some passengers and express packages still cross the Atlantic on 'spiders,' but most of these light cargoes go in a far pleasanter and more rapid way. The deep-displacement vessels, for heavy freight, make little better speed than was made by the same class a hundred years ago. But they are also run entirely by electricity, largely supplied by wind, and by the tide turning their motors, which become dynamos while at anchor in any stream. They therefore need no bulky boilers, engines, sails, or coal-bunkers, and consequently can carry unprecedentedly large cargoes with comparatively small crews. The officers on the bridge and the men in the crow's nest--the way to which is by a ladder INSIDE the mast, to protect the climber from the weather--are about all that is needed; while disablement is made practically impossible, by having four screws, each with its own set of automatically lubricating motors.
"This change, like other labour-saving appliances, at first resulted in laying off a good many men, the least satisfactory being the first to go; but the increase in business was so great that the intelligent men were soon reemployed as officers at higher rates of pay and more interesting work than before, while they as consumers were benefited as much as any one else by the decreased cost of production and transportation.
"With a view to facilitating interchange still further, our Government has gradually completed the double coast-line that Nature gave us in part. This was done by connecting islands separated from shore by navigable water, and leaving openings for ingress and exit but a few hundred yards wide. The breakwaters required to do this were built with cribbing of incorrodible metal, affixed to deeply driven metallic piles, and filled with stones along coasts where they were found in abundance or excess. This, while clearing many fields and improving them for cultivation, provided just the needed material; since irregular stones bind together firmly, and, while also insoluble, combine considerable bulk with weight. South of Hatteras, where stones are scarce, the sand dredged from parts of the channel was filled into the crib, the surface of which has a concave metallic cover, a trough of still water being often the best barrier against the passage of waves. This double coast-line has been a great benefit, and propelled vessels of moderate draught can range in smooth water, carrying very full loads, from Labrador to the Orinoco. The exits are, of course, protected by a line of cribbing a few hundred feet to seaward.
"The rocks have been removed from all channels about New York and other commercial centres, while the shallow places have been dredged to a uniform depth. This diminishes the dangers of navigation and considerably decreases the speed with which the tides rush through. Where the obstructions consisted of reefs surrounded by deep water, their removal with explosives was easy, the shattered fragments being allowed to sink to the bottom and remain there beneath the danger line.
"Many other great works have also been completed. The canals at Nicaragua have been in operation many years, it having been found best to have several sizes of locks, and to use the large ones only for the passage of large vessels. The improved Erie and Champlain Canals also enable ships four hundred feet long to reach New York from the Great Lakes via the Hudson River.
"For flying, we have an aeroplane that came in when we devised a suitable motor power. This is obtained from very light paper-cell batteries that combine some qualities of the primary and secondary type, since they must first be charged from a dynamo, after which they can supply full currents for one hundred hours--enough to take them around the globe--while partly consuming the elements in the cells. The power is applied through turbine screws, half of which are capable of propelling the flat deck in its inclined position at sufficient speed to prevent its falling. The moving parts have ball bearings and friction rollers, lubrication being secured automatically, when required, by a supply of vaseline that melts if any part becomes hot. All the framing is of thin but very durable galvanized aluminum, which has superseded steel for every purpose in which weight is not an advantage, as in the permanent way on railways. The air ships, whose length varies from fifty to five hundred feet, have rudders for giving a vertical or a horizontal motion, and several strengthening keels that prevent leeway when turning. They are entirely on the principle of birds, maintaining themselves mechanically, and differing thus from the unwieldy balloon. Starting as if on a circular railway, against the wind, they rise to a considerable height, and then, shutting off the batteries, coast down the aerial slope at a rate that sometimes touches five hundred miles an hour. When near the ground the helmsman directs the prow upward, and, again turning on full current, rushes up the slope at a speed that far exceeds the eagle's, each drop of two miles serving to take the machine twenty or thirty; though, if the pilot does not wish to soar, or if there is a fair wind at a given height, he can remain in that stratum of the atmosphere by moving horizontally. He can also maintain his elevation when moving very slowly, and though the headway be entirely stopped, the descent is gradual on account of the aeroplane's great spread, the batteries and motors being secured to the under side of the deck.
"The motors are so light that they develop two horse power for every pound of their weight; while, to keep the frames thin, the necessary power is obtained by terrific speed of the moving parts, as though a steam engine, to avoid great pressure in its cylinders, had a long stroke and ran at great piston speed, which, however, is no disadvantage to the rotary motion of the electric motor, there being no reciprocating cranks, etc., that must be started and stopped at each revolution.
"To obviate the necessity of gearing to reduce the number of revolutions to those possible for a large screw, this member is made very small, and allowed to revolve three thousand times a minute, so that the requisite power is obtained with great simplicity of mechanism, which further decreases friction. The shafts, and even the wires connecting the batteries with the motors, are made large and hollow. Though the primary battery pure and simple, as the result of great recent advances in chemistry, seems to be again coming up, the best aeroplane batteries are still of the combination-storage type. These have been so perfected that eight ounces of battery yield one horse power for six hours, so that two pounds of battery will supply a horse power for twenty-four hours; a small fifty-horse-power aeroplane being therefore able to fly four days with a battery weight of but four hundred pounds.
"Limestone and clarified acid are the principal parts of these batteries. It was known long ago that there was about as much imprisoned solar energy in limestone as in coal, but it was only recently that we discovered this way of releasing and using it.
"Common salt plays an important part in many of our chemical reactions. By combining it with limestone, and treating this with acid jelly, we also get good results on raising to the boiling-point.
"However enjoyable the manly sport of yachting is on water, how vastly more interesting and fascinating it is for a man to have a yacht in which he can fly to Europe in one day, and with which the exploration of tropical Africa or the regions about the poles is mere child's play, while giving him so magnificent a bird's-eye view! Many seemingly insoluble problems are solved by the advent of these birds. Having as their halo the enforcement of peace, they have in truth taken us a long step towards heaven, and to the co-operation and higher civilization that followed we shall owe much of the success of the great experiment on Mother Earth now about to be tried.
"Another change that came in with a rush upon the discovery of a battery with insignificant weight, compact form, and great capacity, was the substitution of electricity for animal power for the movement of all vehicles. This, of necessity brought in good roads, the results obtainable on such being so much greater than on bad ones that a universal demand for them arose. This was in a sense cumulative, since the better the streets and roads became, the greater the inducement to have an electric carriage. The work of opening up the country far and near, by straightening and improving existing roads, and laying out new ones that combine the solidity of the Appian Way with the smoothness of modern asphalt, was largely done by convicts, working under the direction of State and Government engineers. Every State contained a horde of these unprofitable boarders, who, as they formerly worked, interfered with honest labour, and when idle got into trouble. City streets had been paved by the municipality; country roads attended to by the farmers, usually very unscientifically. Here was a field in which convict labour would not compete, and an important work could be done. When once this was made the law, every year showed improvement, while the convicts had useful and healthful occupation.
"The electric phaetons, as those for high speed are called, have three and four wheels, and weigh, including battery and motor, five hundred to four thousand pounds. With hollow but immensely strong galvanically treated aluminum frames and pneumatic or cushion tires, they run at thirty-five and forty miles an hour on country roads, and attain a speed over forty on city streets, and can maintain this rate without recharging for several days. They can therefore roam over the roads of the entire hemisphere, from the fertile valley of the Peace and grey shores of Hudson Bay, to beautiful Lake Nicaragua, the River Plate, and Patagonia, improving man by bringing him close to Nature, while they combine the sensations of coasting with the interest of seeing the country well.
"To recharge the batteries, which can be done in almost every town and village, two copper pins attached to insulated copper wires are shoved into smooth-bored holes. These drop out of themselves by fusing a small lead ribbon, owing to the increased resistance, when the acid in the batteries begins to 'boil,' though there is, of course, but little heat in this, the function of charging being merely to bring about the condition in which part of the limestone can be consumed, the batteries themselves, when in constant use, requiring to be renewed about once a month. A handle at the box seat turns on any part of the attainable current, for either going ahead or reversing, there being six or eight degrees of speed for both directions, while the steering is done with a small wheel.
"Light but powerful batteries and motors have also been fitted on bicycles, which can act either as auxiliaries for hill-climbing or in case of head wind, or they can propel the machine altogether.
"Gradually the width of the streets became insufficient for the traffic, although the elimination of horses and the consequent increase in speed greatly augmented their carrying capacity, until recently a new system came in. The whole width of the avenues and streets in the business parts of the city, including the former sidewalks, is given up to wheel traffic, an iron ridge extending along the exact centre to compel vehicles to keep to the right. Strips of nickel painted white, and showing a bright phosphorescence at night, are let into the metal pavement flush with the surface, and run parallel to this ridge at distances of ten to fifteen feet, dividing each half of the avenue into four or five sections, their width increasing as they approach the middle. All trucks or drays moving at less than seven miles an hour are obliged to keep in the section nearest the building line, those running between seven and fifteen in the next, fifteen to twenty-five in the third, twenty-five to thirty-five in the fourth, and everything faster than that in the section next the ridge, unless the avenue or street is wide enough for further subdivisions. If it is wide enough for only four or less, the fastest vehicles must keep next the middle, and limit their speed to the rate allowed in that section, which is marked at every crossing in white letters sufficiently large for him that runs to read. It is therefore only in the wide thoroughfares that very high speed can be attained. In addition to the crank that corresponds to a throttle, there is a gauge on every vehicle, which shows its exact speed in miles per hour, by gearing operated by the revolutions of the wheels.
"The policemen on duty also have instantaneous kodaks mounted on tripods, which show the position of any carriage at half- and quarter-second intervals, by which it is easy to ascertain the exact speed, should the officers be unable to judge it by the eye; so there is no danger of a vehicle's speed exceeding that allowed in the section in which it happens to be; neither can a slow one remain on the fast lines.
"Of course, to make such high speed for ordinary carriages possible, a perfect pavement became a sine qua non. We have secured this by the half-inch sheet of steel spread over a carefully laid surface of asphalt, with but little bevel; and though this might be slippery for horses' feet, it never seriously affects our wheels. There being nothing harder than the rubber ties of comparatively light drays upon it--for the heavy traffic is carried by electric railways under ground--it will practically never wear out.
"With the application of steel to the entire surface, car-tracks became unnecessary, ordinary wheels answering as well as those with flanges, so that no new tracks were laid, and finally the car companies tore up the existing ones, selling them in many instances to the municipalities as old iron. Our streets also need but little cleaning; neither is the surface continually indented, as the old cobble-stones and Belgian blocks were, by the pounding of the horses' feet, so that the substitution of electricity for animal power has done much to solve the problem of attractive streets.
"Scarcely a ton of coal comes to Manhattan Island or its vicinity in a year. Very little of it leaves the mines, at the mouths of which it is converted into electricity and sent to the points of consumption by wire, where it is employed for all uses to which fuel was put, and many others. Consequently there is no smoke, and the streets are not encumbered with coal-carts; the entire width being given up to carriages, etc. The ground floors in the business parts are used for large warehouses, trucks running in to load and unload. Pedestrians therefore have sidewalks level with the second story, consisting of glass floors let into aluminum frames, while all street crossings are made on bridges. Private houses have a front door opening on the sidewalk, and another on the ground level, so that ladies paying visits or leaving cards can do so in carriages. In business streets the second story is used for shops. In place of steel covering, country roads have a thick coating of cement and asphalt over a foundation of crushed stone, giving a capital surface, and have a width of thirty-three feet (two rods) in thinly settled districts, to sixty-six feet (four rods) where the population is greater. All are planted with shade and fruit trees, while the wide driveways have one or two broad sidewalks. The same rule of making the slow-moving vehicles keep near the outside prevails, though the rate of increase in speed on approaching the middle is more rapid than in cities, and there is usually no dividing ridge. On reaching the top of a long and steep hill, if we do not wish to coast, we convert the motors into dynamos, while running at full speed, and so change the kinetic energy of the descent into potential in our batteries. This twentieth-century stage-coaching is one of the delights to which we are heirs, though horses are still used by those that prefer them.
"We have been much aided in our material progress by the facility with which we obtain the metals. It was observed, some time ago, that when artesian and oil wells had reached a considerable depth, what appeared to be drops of lead and antimony came up with the stream. It finally occurred to a well-borer that if he could make his drill hard enough and get it down far enough, keeping it cool by solidified carbonic acid during the proceeding, he would reach a point at which most of the metals would be viscous, if not actually molten, and on being freed from the pressure of the crust they would expand, and reach the surface in a stream. This experiment he performed near the hot geysers in Yellowstone Park, and what was his delight, on reaching a depth scarcely half a mile beyond his usual stopping-place, to be rewarded by a stream of metal that heralded its approach by a loud explosion and a great rush of superheated steam! It ran for a month, completely filling the bed of a small, dried-up river, and when it did stop there were ten million tons in sight. This proved the feasibility of the scheme, and, though many subsequent attempts were less successful, we have learned by experience where it is best to drill, and can now obtain almost any metal we wish.
"'Magnetic eyes' are of great use to miners and Civil engineers. These instruments are something like the mariner's compass, with the sensitiveness enormously increased by galvanic currents. The 'eye,' as it were, sees what substances are underground, and at what distances. It also shows how many people are in an adjoining room--through the magnetic properties of the iron in their blood--whether they are moving, and in what directions and at what speed they go. In connection with the phonograph and concealed by draperies, it is useful to detectives, who, through a registering attachment, can obtain a record of everything said and done.
"Our political system remains with but little change. Each State has still two United States Senators, though the population represented by each representative has been greatly increased, so that the Senate has grown numerically much more than the House. It is the duty of each member of Congress to understand the conditions existing in every other member's State or district, and the country's interest always precedes that of party. We have a comprehensive examination system in the civil service, and every officeholder, except members of the Cabinet, retains his office while efficiently performing his duty, without regard to politics. The President can also be re-elected any number of times. The Cabinet members, as formerly, usually remain in office while he does, and appear regularly in Congress to defend their measures.
"The really rapid transit lines in New York are underground, and have six tracks, two being used for freight. At all stations the local tracks rise several feet towards the street and slope off in both directions, while the express tracks do this only at stations at which the faster trains stop. This gives the passengers a shorter distance to descend or rise in the elevators, and the ascent before the stations aids the brakes in stopping, while the drop helps the motors to start the trains quickly in getting away.
"Photography has also made great strides, and there is now no difficulty in reproducing exactly the colours of the object taken.
"Telephones have been so improved that one person can speak in his natural voice with another in any part of the globe, the wire that enables him to hear also showing him the face of the speaker though he be at the antipodes. All telephone wires being underground and kept by themselves, they are not interfered with by any high-tension electric-light or power wires, thunderstorms, or anything else.
"Rain-making is another subject removed from the uncertainties, and has become an absolute science. We produce clouds by explosions in the atmosphere's heights and by surface air forced by blowers through large pipes up the side of a mountain or natural elevation and there discharged through an opening in the top of a tower built on the highest part. The aëriduct is incased in a poor heat-conductor, so that the air retains its warmth until discharged, when it is cooled by expansion and the surrounding cold air. Condensation takes place and soon serves to start a rain.
"Yet, until the earth's axis is straightened, we must be more or less dependent on the eccentricities of the weather, with extremes of heat and cold, droughts and floods, which last are of course largely the result of several months' moisture held on the ground in the form of snow, the congestion being relieved suddenly by the warm spring rains.
"Medicine and surgery have kept pace with other improvements--inoculation and antiseptics, as already seen, rendering most of the germ diseases and formerly dreaded epidemics impotent; while through the potency of electrical affinity we form wholesome food-products rapidly, instead of having to wait for their production by Nature's slow processes.
"The metric system, now universal, superseded the old-fashioned arbitrary standards, so prolific of mistakes and confusion, about a century ago.
"English, as we have seen, is already the language of 600,000,000 people, and the number is constantly increasing through its adoption by the numerous races of India, where, even before the close of the last century, it was about as important as Latin during the greatness of Rome, and by the fact that the Spanish and Portuguese elements in Mexico and Central and South America show a constant tendency to die out, much as the population of Spain fell from 30,000,000 to 17,000,000 during the nineteenth century. As this goes on, in the Western hemisphere, the places left vacant are gradually filled by the more progressive Anglo-Saxons, so that it looks as if the study of ethnology in the future would be very simple.
"The people with cultivation and leisure, whose number is increasing relatively to the population at each generation, spend much more of their year in the country than formerly, where they have large and well-cultivated country seats, parts of which are also preserved for game. This growing custom on the part of society, in addition to being of great advantage to the out-of-town districts, has done much to save the forests and preserve some forms of game that would otherwise, like the buffalo, have become extinct.
"In astronomy we have also made tremendous strides. The old-fashioned double-convex lens used in telescopes became so heavy as its size grew, that it bent perceptibly from its own weight, when pointed at the zenith, distorting the vision; while when it was used upon a star near the horizon, though the glass on edge kept its shape, there was too much atmosphere between it and the observed object for successful study. Our recent telescopes have, therefore, concave plate-glass mirrors, twenty metres in diameter, like those used for converging the sun's rays in solar engines, but with curves more mathematically exact, which collect an immense amount of light and focus it on a sensitive plate or on the eye of the observer, whose back is turned to the object he is studying. An electrical field also plays an important part, the electricity being as great an aid to light as in the telephone it is to sound. With these placed generally on high mountain peaks, beyond the reach of clouds, we have enormously increased the number of visible stars, though there are still probably boundless regions that we cannot see. These telescopes have several hundred times the power of the largest lenses of the nineteenth century, and apparently bring Mars and Jupiter, when in opposition, within one thousand and ten thousand miles, respectively, so that we study their physical geography and topography; and we have good maps of Jupiter, and even of Saturn, notwithstanding their distance and atmospheric envelopes, and we are able to see the disks of third-magnitude stars.
"It seems as if, when we wish any particular discovery or invention, in whatever field, we had but to turn our efforts in its direction to obtain our desire. We seem, in fact, to have awakened in the scenes of the Arabian Nights; yet the mysterious genius which we control, and which dims Aladdin's lamp, is the gift of no fairy godmother sustained by the haze of dreams, but shines as the child of science with fadeless and growing splendour, and may yet bring us and our little planet much closer to God.
"We should indeed be happy, living as we do at this apex of attained civilization, with the boundless possibilities of the future unfolding before us, on the horizon of which we may fairly be said to stand.
"We are freed from the rattling granite pavement of only a century ago, which made the occupant of an omnibus feel like a fly inside of a drum; from the domination of our local politics by ignorant foreigners; and from country roads that either filled the eyes, lungs, and hair of the unfortunates travelling upon them with dust, or, resembling ploughed and fertilized fields, saturated and plastered them with mud. These miseries, together with sea-sickness in ocean travelling, are forever passed, and we feel that 'Excelsior!' is indeed our motto. Our new and increasing sources of power have so stimulated production and manufacturing that poverty or want is scarcely known; while the development of the popular demand, as a result of the supplied need, is so great that there is no visible limit to the diversification of industry or the possibilities of the arts.
"It may seem strange to some that apparently so disproportionate a number of inventions have been made in the last century. There are several reasons. Since every discovery or advance in knowledge increases our chance of obtaining more, it becomes cumulative, and our progress is in geometric instead of arithmetical ratio. Public interest and general appreciation of the value of time have also effectively assisted progress. At the beginning of each year the President, the Governors of the States, and the Mayors of cities publish a prospectus of the great improvements needed, contemplated, and under way within their jurisdiction--it may be planning a new boulevard, a new park, or an improved system of sewers; and at the year's end they issue a resume of everything completed, and the progress in everything else; and though there is usually a great difference between the results hoped for and those attained, the effect is good. The newspapers publish at length the recommendations of the Executives, and also the results obtained, and keep up public interest in all important matters.
"Free to delve in the allurement and fascination of science, emancipated man goes on subduing Nature, as his Maker said he should, and turning her giant forces to his service in his constant struggle to rise and become more like Him who gave the commandments and showed him how he should go.
"Notwithstanding our strides in material progress, we are not entirely content. As the requirements of the animal become fully supplied, we feel a need for something else. Some say this is like a child that cries for the moon, but others believe it the awakening and craving of our souls. The historian narrates but the signs of the times, and strives to efface himself; yet there is clearly a void, becoming yearly more apparent, which materialism cannot fill. Is it some new subtle force for which we sigh, or would we commune with spirits? There is, so far as we can see, no limit to our journey, and I will add, in closing, that, with the exception of religion, we have most to hope from science."
Knowing that the rectification of the earth's axis was satisfactorily begun, and that each year would show an increasing improvement in climate, many of the delegates, after hearing Bearwarden's speech, set out for their homes. Those from the valley of the Amazon and the eastern coast of South America boarded a lightning express that rushed them to Key West at the rate of three hundred miles an hour. The railroad had six tracks, two for through passengers, two for locals, and two for freight. There they took a "water-spider," six hundred feet long by three hundred in width, the deck of which was one hundred feet above the surface, which carried them over the water at the rate of a mile a minute, around the eastern end of Cuba, through Windward Passage, and so to the South American mainland, where they continued their journey by rail.
The Siberian and Russian delegates, who, of course, felt a keen interest in the company's proceedings, took a magnetic double-ender car to Bering Strait. It was eighteen feet high, one hundred and fifty feet long, and had two stories. The upper, with a toughened glass dome running the entire length, descended to within three feet of the floor, and afforded an unobstructed view of the rushing scenery. The rails on which it ran were ten feet apart, the wheels being beyond the sides, like those of a carriage, and fitted with ball bearings to ridged axles. The car's flexibility allowed it to follow slight irregularities in the track, while the free, independent wheels gave it a great advantage in rounding curves over cars with wheels and axle in one casting, in which one must slip while traversing a greater or smaller arc than the other, except when the slope of the tread and the centrifugal force happen to correspond exactly. The fact of having its supports outside instead of underneath, while increasing its stability, also enabled the lower floor to come much nearer the ground, while still the wheels were large. Arriving in just twenty hours, they ran across on an electric ferry-boat, capable of carrying several dozen cars, to East Cape, Siberia, and then, by running as far north as possible, had a short cut to Europe.
The Patagonians went by the all-rail Intercontinental Line, without change of cars, making the run of ten thousand miles in forty hours. The Australians entered a flying machine, and were soon out of sight; while the Central Americans and members from other States of the Union returned for the most part in their mechanical phaetons.
"A prospective improvement in travelling," said Bearwarden, as he and his friends watched the crowd disperse, "will be when we can rise beyond the limits of the atmosphere, wait till the earth revolves beneath us, and descend in twelve hours on the other side."
"True," said Cortlandt, "but then we can travel westward only, and shall have to make a complete circuit when we wish to go east."
A few days later there was a knock at President Bearwarden's door, while he was seated at his desk looking over some papers and other matters. Taking his foot from a partly opened desk drawer where it had been resting, he placed it upon the handle of a handsome brass-mounted bellows, which proved to be articulating, for, as he pressed, it called lustily, "Come in!" The door opened, and in walked Secretary of State Stillman, Secretary of the Navy Deepwaters, who was himself an old sailor, Dr. Cortlandt, Ayrault, Vice-President Dumby, of the T. A. S. Co., and two of the company's directors.
"Good-morning," said Bearwarden, as he shook hands with his visitors. "Charmed to see you."
"That's a great invention," said Secretary Stillman, examining the bellows. "We must get Congress to make an appropriation for its introduction in the department buildings in Washington. You have no idea how it dries my throat to be all the time shouting, 'Come in!'"
"Do you know, Bearwarden," said Secretary Deepwaters, "I'm afraid when we have this millennium of climate every one will be so well satisfied that our friend here (pointing to Secretary Stillman with his thumb) will have nothing to do."
"I have sometimes thought some of the excitement will be gone, and the struggle of the 'survival of the fittest' will become less problematical," said Bearwarden.
"The earth seems destined to have a calm old age," said Cortlandt, "unless we can look to the Cabinet to prevent it."
"This world will soon be a dull place. I wish we could leave it for a change," said Ayrault. "I don't mean forever, of course, but just as people have grown tired of remaining like plants in the places in which they grew. Alan has been a caterpillar for untold ages; can he not become the butterfly?"
"Since we have found out how to straighten the axis," said Deepwaters, "might we not go one better, and improve the orbit as well?--increase the difference between aphelion and perihelion, and give those that still like a changing climate a chance, while incidentally we should see more of the world--I mean the solar system--and, by enlarging the parallax, be able to measure the distance of a greater number of fixed stars. Put your helm hard down and shout 'Hard-a-lee!' You see, there is nothing simpler. You keep her off now, and six months hence you let her luff."
"That's an idea!" said Bearwarden. "Our orbit could be enough like that of a comet to cross the orbits of both Venus and Mars; and the climatic extremes would not be inconvenient. The whole earth being simultaneously warmed or cooled, there would be no equinoctials or storms resulting from changes on one part of the surface from intense heat to intense cold; every part would have a twelve-hour day and night, and none would be turned towards or from the sun for six months at a time; for, however eccentric the orbit, we should keep the axis absolutely straight. At perihelion there would simply be increased evaporation and clouds near the equator, which would shield those regions from the sun, only to disappear again as the earth receded.
"The only trouble," said Cortlandt, "is that we should have no fulcrum. Straightening the axis is simple enough, for we have the attraction of the sun with which to work, and we have but to increase it at one end while decreasing it at the other, and change this as the poles change their inclination towards the sun, to bring it about. If a comet with a sufficiently large head would but come along and retard us, or opportunely give us a pull, or if we could increase the attraction of the other planets for us, or decrease it at times, it might be done. If the force, the control of which was discovered too late to help us straighten the axis, could be applied on a sufficiently large scale; if apergy----"
"I have it!" exclaimed Ayrault, jumping up. "Apergy will do it. We can build an airtight projectile, hermetically seal ourselves within, and charge it in such a way that it will be repelled by the magnetism of the earth, and it will be forced from it with equal or greater violence than that with which it is ordinarily attracted. I believe the earth has but the same relation to space that the individual molecule has to any solid, liquid, or gaseous matter we know; and that, just as molecules strive to fly apart on the application of heat, this earth will repel that projectile when electricity, which we are coming to look upon as another form of heat, is properly applied. It must be so, and it is the manifest destiny of the race to improve it. Man is a spirit cursed with a mortal body, which glues him to the earth, and his yearning to rise, which is innate, is, I believe, only a part of his probation and trial."
"Show us how it can be done," shouted his listeners in chorus.
"Apergy is and must be able to do it," Ayrault continued. "Throughout Nature we find a system of compensation. The centripetal force is offset by the centrifugal; and when, according to the fable, the crystal complained of its hard lot in being unable to move, while the eagle could soar through the upper air and see all the glories of the world, the bird replied, 'My life is but for a moment, while you, set in the rock, will live forever, and will see the last sunrise that flashes upon the earth.'
"We know that Christ, while walking on the waves, did not sink, and that he and Elijah were carried up into heaven. What became of their material bodies we cannot tell, but they were certainly superior to the force of gravitation. We have no reason to believe that in miracles any natural law was broken, or even set aside, but simply that some other law, whose workings we do not understand, became operative and modified the law that otherwise would have had things its own way. In apergy we undoubtedly have the counterpart of gravitation, which must exist, or Nature's system of compensation is broken. May we not believe that in Christ's transfiguration on the mount, and in the appearance of Moses and Elias with him--doubtless in the flesh, since otherwise mortal eyes could not have seen them--apergy came into play and upheld them; that otherwise, and if no other modification had intervened, they would have fallen to the ground; and that apergy was, in other words, the working principle of those miracles?"
"May we not also believe," added Cortlandt, "that in the transfiguration Christ's companions took the substance of their material bodies--the oxygen, hydrogen, nitrogen, and carbon--from the air and the moisture it contained; for, though spiritual bodies, be their activity magnetic or any other, could of course pass the absolute cold and void of space without being affected, no mortal body could; and that in the same manner Elijah's body dissolved into air without the usual intervention of decomposition; for we know that, though matter can easily change its form, it can never be destroyed."
All assented to this, and Ayrault continued: "If apergy can annul gravitation, I do not see why it should not do more, for to annul it the repulsion of the earth that it produces must be as great as its attraction, unless we suppose gravitation for the time being to be suspended; but whether it is or not, does not affect the result in this case, for, after the apergetic repulsion is brought to the degree at which a body does not fall, any increase in the current's strength will cause it to rise, and in the case of electro-magnets we know that the attraction or repulsion has practically no limit. This will be of great advantage to us," he continued, "for if a projectile could move away from the earth with no more rapid acceleration than that with which it approaches, it would take too long to reach the nearest planet, but the maximum repulsion being at the start by reason of its proximity to the earth--for apergy, being the counterpart of gravitation, is subject to Newton's and Kepler's laws--the acceleration of a body apergetically charged will be greatest at first. Two inclined planes may have the same fall, but a ball will reach the bottom of one that is steepest near the top in less time than on any other, because the maximum acceleration is at the start. We are all tired of being stuck to this cosmical speck, with its monotonous ocean, leaden sky, and single moon that is useless more than half the time, while its size is so microscopic compared with the universe that we can traverse its great circle in four days. Its possibilities are exhausted; and just as Greece became too small for the civilization of the Greeks, and as reproduction is growth beyond the individual, so it seems to me that the future glory of the human race lies in exploring at least the solar system, without waiting to become shades."
"Should you propose to go to Mars or Venus?" asked Cortlandt.
"No," replied Ayrault, "we know all about Mars; it is but one seventh the size of the earth, and as the axis is inclined more than ours, it would be a less comfortable globe than this; while, as our president here told us in his T. A. S. Company's report, the axis of Venus is inclined to such a degree that it would be almost uninhabitable for us. It would be as if colonists tried to settle Greenland, or had come to North America during its Glacial period. Neither Venus nor Mars would be a good place now."
"Where should you propose to go?" asked Stillman.
"To Jupiter, and, if possible, after that to Saturn," replied Ayrault; "the former's mean distance from the sun is 480,000,000 miles; but, as our president showed us, its axis is so nearly straight that I think, with its internal warmth, there will be nothing to fear from cold. Though, on account of the planet's vast size, objects on its surface weigh more than twice as much as here, if I am able to reach it by means of apergy, the same force will enable me to regulate my weight. Will any one go with me?"
"Splendid!" said Bearwarden. "If Mr. Dumby, our vice-president, will temporarily assume my office, nothing will give me greater pleasure."
"So will I go, if there is room for me," said Cortlandt. "I will at once resign my place as Government expert, and consider it the grandest event of my life."
"If I were not afraid of leaving Stillman here to his own devices, I'd ask for a berth as well," said Deepwaters.
"I am afraid," said Stillman, "if you take any more, you will be overcrowded."
"Modesty forbids his saying," said Deepwaters, "that it wouldn't do for the country to have all its eggs in one basket."
"Are you not afraid you will find the surface hot, or even molten?" asked Vice-President Dumby. "With its eighty-six thousand five hundred mile diameter, the amount of original internal heat must have been terrific."
"No," said Cortlandt, "it cannot be molten, or even in the least degree luminous, for, if it were, its satellites would be visible when they enter its shadow, whereas they entirely disappear."
"I do not believe Jupiter's surface is even perceptibly warm," said Bearwarden. "We know that Algol, known to the ancients as the 'Demon Star,' and several other variable stars, are accompanied by a dark companion, with which they revolve about a common centre, and which periodically obscures part of their light. Now, some of these non-luminaries are nearly as large as our sun, and, of course, many hundred times the size of Jupiter. If these bodies have lost enough heat to be invisible, Jupiter's surface at least must be nearly cold."
"In the phosphorescence of seawater," said Cortlandt, "and in other instances in Nature, we find light without heat, and we may soon be able to produce it in the arts by oxidizing coal without the intervention of the steam engine; but we never find any considerable heat without light."
"I am convinced," said Bearwarden, "that we shall find Jupiter habitable for intelligent beings who have been developed on a more advanced sphere than itself, though I do not believe it has progressed far enough in its evolution to produce them. I expect to find it in its Palaeozoic or Mesozoic period, while over a hundred years ago the English astronomer, Chambers, thought that on Saturn there was good reason for suspecting the presence of snow."
"What sort of spaceship do you propose to have?" asked the vice-president.
"As you have to pass through but little air," said Deepwaters, "I should suggest a short-stroke cylinder of large diameter, with a flat base and dome roof, composed of aluminum, or, still better, of glucinum or beryllium as it is sometimes called, which is twice as good a conductor of electricity as aluminum, four times as strong, and is the lightest of all known metals, having a specific gravity of only two, which last property will be of great use to you, for of course the more weight you have to propel the more apergetic repulsion you will have to develop."
"I will get some drawing-paper I left outside in my trap," said Ayrault, "when with your ideas we may arrive at something definite," saying which, he left the room.
"He seems very cynical in his ideas of life and the world in general," said Secretary Stillman, "for a man of his age, and one that is engaged."
"You see," replied Bearwarden, "his fiancee is not yet a senior, being in the class of two thousand and one at Vassar, and so cannot marry him for a year. Not till next June can this sweet girl graduate come forth with her mortar-board and sheepskin to enlighten the world and make him happy. That is, I suspect, one reason why he proposed this trip."
In a few moments Ayrault returned with pencils, a pair of compasses, and paper.
"Let us see, in the first place," said Deepwaters, "how long the journey will take. Since a stone falls 16.09 feet the first second, and 64+ feet the next, it is easy to calculate at what rate your speed would increase with the repulsion twice that of the ordinary traction. But I think this would be too slow. It will be best to treble or quadruple the apergetic charge, which can easily be done, in which case your speed will exceed the muzzle-velocity of a projectile from a long-range gun, in a few seconds. As the earth's repulsion decreases, the attraction of mars and Jupiter will increase, and, there being no resistance, your gait will become more and more rapid till it is necessary to reverse the charge to avoid being dashed to pieces or being consumed like a falling star by the friction in passing through Jupiter's atmosphere. You can be on the safe side by checking your speed in advance. You must, of course, be careful to avoid collisions with meteors and asteroids but if you do, they will be of use to you, for by attracting or repelling them you can change your course to suit yourself, and also theirs in inverse ratio to their masses. Jupiter's moons will be like head and stern lines in enabling you to choose the part of the surface on which you wish to land. With apergy it is as essential to have some heavy body on which to work, within range, as to have water about a ship's propellers. Whether, when apergy is developed, gravitation is temporarily annulled, or reversed like the late attraction of a magnet when the current is changed, or whether it is merely overpowered, in which case your motion will be the resultant of the two, is an unsettled and not very important point; for, though we know but little more of the nature of electricity than was known a hundred years ago, this does not prevent our producing and using it."
"Jupiter, when in opposition," he continued, "is about 380,000,000 miles from us, and it takes light, which travels at the rate of 190,000 miles a second, just thirty-four minutes to reach the earth from Jupiter. If we suppose the average speed of your ship to be one-five-hundredth as great, it will take you just eleven days, nineteen hours and twenty minutes to make the journey. You will have a fine view of Mars and the asteroids, and when 1,169,000 miles from Jupiter, will cross the orbit of Callisto, the fifth moon in distance from the giant planet. That will be your best point to steer by."
"I think," said Ayrault, "as that will be the first member of Jupiter's system we pass, and as it will guide us into port, it would be a good name for our ship, and you must christen her if we have her launched."
"No, no," said Deepwaters, "Miss Preston must do that; but we certainly should have a launch, for you might have to land in the water, and you must be sure the ship is tight."
"Talking of tight ships," said Bearwarden, passing a decanter of claret to Stillman, "may remind us that it is time to splice the 'main brace.' There's a bottle of whisky and some water just behind you," he added to Deepwaters, "while three minutes after I ring this bell," he said, pressing a button and jerking a handle marked '8,' "the champagne cocktails will be on the desk."
"I see you know his ways," said Stillman to Bearwarden, drooping his eyes in Deepwaters's direction.
"Oh, yes, I've been here before," replied Deepwaters. "You see, we navy men have to hustle now-a-days, and can't pass our time in a high-backed chair, talking platitudes."
At this moment there was a slight rumbling, and eight champagne cocktails, with the froth still on, and straws on a separate plate, shot in and landed on a corner of the desk.
"Help yourselves, gentlemen," said Bearwarden, placing them on a table; "I hope we shall find them cold."
"Do you know," said Deepwaters to Ayrault, while rapidly making his cocktail disappear, "the Callisto's cost with its outfit will be very great, especially if you use glucinum, which, though the ideal metal for the purpose, comes pretty high? I suggest that you apply to Congress for an appropriation. This experiment comes under the 'Promotion of Science Act,' and any bill for it would certainly pass."
"No, indeed," replied Ayrault; "the Callisto trip will be a privilege and glory I would not miss, and building her will be a part of it. I shall put in everything conducive to success, but will come to the Government only for advice."
"I will send a letter to all our ambassadors and consuls," said Stillman, "to telegraph the department anything they may know or learn that will be of use in adjusting the batteries, controlling the machine, or anything else, and will turn over to you in a succinct form all information that may be relevant, for without such sorting you would be overwhelmed."
"And I," said Deepwaters, "will order the commanders of our vessels to give you a farewell salute at starting, and to pick you up in case you fail. When you have demonstrated the suitability of apergy," he continued, "and the habitability of Jupiter and Saturn--,which, with their five and eight moons, respectively, and rings thrown in, must both be vastly superior to our little second-rate globe--we will see what can be done towards changing our orbit, and if we cannot swing a little nearer to our new world or worlds. Then we'll lower, or rather raise, the boats in the shape of numerous Callistos, and have a landing-party ready at each opposition, while a man or two can be placed in charge of each projectile to bring it back in ballast. Thus we may soon have regular interplanetary lines."
"As every place seems to have been settled from some other," said Cortlandt, "I do not see why, with increased scientific facilities, history should not repeat itself, and this be the point from which to colonize the solar system; for, for the present at least, it would seem that we could not get beyond that."
"As it will be quite an undertaking to change the orbit," said Deepwaters, "we shall have time meanwhile to absorb or run out all inferior races, so that we shall not make the mistake of extending the Tower of Babel."
"He is putting on his war-paint," said Stillman, "and will soon want a planet to himself."
"I see no necessity for even changing the orbit," said Bearwarden, "except for the benefit of those that remain. If this attempt succeeds, it can doubtless be repeated. An increase in eccentricity would merely shorten the journey, if aphelion always coincided with opposition, which it would not."
"Let us know how you are getting on," said Deepwaters to Ayrault, "and be sure you have the Callisto properly christened. Step lively there, landlubbers!" he called to Stillman; "I have an appointment at Washington at one, and it is now twenty minutes past twelve. We can lunch on the way."
Ayrault immediately advertised for bids for the construction of a glucinum cylinder twenty-five feet in diameter, fifteen feet high at the sides, with a domed roof, bringing up the total height to twenty-one feet, and with a small gutter about it to catch the rain on Jupiter or any other planet they might visit. The sides, roof, and floor were to consist of two sheets, each one third of an inch thick and six inches apart, the space between to be filled with mineral wool, as a protection against the intense cold of space. There were also to be several keels and supports underneath, on which the car should rest. Large, toughened plate-glass windows were to be let into the roof and sides, and smaller ones in the floor, all to be furnished with thick shades and curtains. Ayrault also decided to have it divided into two stories, with ceilings six and a half to seven and a half feet high, respectively, with a sort of crow's nest or observatory at the top; the floors to be lattice-work, like those in the engine-room of a steamer, so that when the carpets were rolled up they should not greatly obstruct the view. The wide, flat base and the low centre of gravity would, he saw, be of use in withstanding the high winds that he knew often prevailed on Jupiter.
As soon as possible he awarded the contract, and then entering his smart electric trap, steered for Vassar University along what was the old post-road--though its builders would not have recognized it with its asphalt surface, straightened curves, and easy grades--to ask his idol to christen the Callisto when it should be finished.
Starting from the upper end of Central Park, he stopped to buy her a bunch of violets, and then ran to Poughkeepsie in two hours.
Sylvia Preston was a lovely girl, with blue eyes, brown hair, and perfect figure, clear white skin, and just twenty. She was delighted to see him, and said she would love to christen the Callisto or do anything else that he wished. "But I am so sorry you are going away," she went on. "I hate to lose you for so long, and we shall not even be able to write."
"Why couldn't we be married now," he asked, "and go to Jupiter for our honeymoon?"
"I'm afraid, dear," she answered, "you would be sorry a few years hence if I didn't take my degree; and, besides, as you have asked those other men, there wouldn't be room for me."
"We could have made other arrangements," he replied, "had I been able to persuade you to go."
"Won't you dine with us at Delmonico's this evening, and go to the play?" she asked. "Papa has taken a box."
"Of course I will," he said, brightening up. "What are you going to wear?"
"Oh, I suppose something light and cool, for it's so hot," she answered.
"I'll go now, so as to be ready," he said, getting up and going towards the door to which Sylvia followed him.
A man in livery stood at the step of the phaeton. Ayrault got in and turned on the current, and his man climbed up behind.
On turning into the main road Ayrault was about to increase his speed, when Sylvia, who had taken a short cut appeared at the wayside carrying her hat in one hand and her gloves in the other.
"I couldn't let you go all by yourself," she said. "The fact is, I wanted to be with you."
"You are the sweetest thing that ever lived, and I'll love you all my days," he said, getting down and helping Sylvia to the seat beside him. "What a nuisance this fellow behind is!" he continued--referring to the groom--"for, though he is a Russian, and speaks but little English, it is unpleasant to feel he is there."
"You'll have to write your sweet nothings, instead of saying them," Sylvia replied.
"For you to leave around for other girls to see," answered Ayrault with a smile.
"I don't know what your other girls do," she returned, "but with me you are safe."
Ayrault fairly made his phaeton spin, going up the grades like a shot and down like a bird. On reaching New York, he left Sylvia at her house, then ran his machine to a florist's, where he ordered some lilies and roses, and then steered his way to his club, where he dressed for dinner. Shortly before the time he repaired to Delmonico's--which name had become historical, though the founders themselves were long dead--and sat guard at a table till Sylvia, wearing his flowers and looking more beautiful than any of them, arrived with her mother and father, and Bearwarden, whom they knew very well.
"How are the exams getting on, Miss Preston?" Bearwarden asked.
"Pretty well," she replied, with a smile. "We had English literature yesterday, and natural history the day before. Next week we have chemistry and philosophy."
"What are you taking in natural history?" asked Bearwarden, with interest.
"Oh, principally physical geography, geology, and meteorology," she replied. "I think them entrancing."
"It must be a consolation," said Ayrault, "when your best hat is spoiled by rain, to know the reason why. Your average," he continued, addressing Sylvia, "was ninety in the semi-annuals, and I haven't a doubt that the finals will maintain your record for the year."
"Don't be too sure," she replied. "I have been loafing awfully, and had to engage a 'grind' as a coach."
After dinner they went to the play, where they saw a presentation of Society at the Close of the Twentieth Century, which Sylvia and Ayrault enjoyed immensely.
A few days after the Delmonico dinner, while Bearwarden, Cortlandt, and Ayrault sat together discussing their plans, the servant announced Ayrault's family physician, Dr. Tubercle Germiny, who had been requested to call.
"Delighted to see you, doctor," said Ayrault, shaking hands. "You know Col. Bearwarden, our President, and Dr. Cortlandt--an LL. D., however, and not a medico."
"I have had the pleasure," replied Dr. Germiny, shaking hands with both.
"As you may be aware, doctor," said Ayrault, when they were seated, "we are about to take a short trip to Jupiter, and, if time allows, to Saturn. We have come to you, as one familiar with every known germ, for a few precautionary suggestions and advice concerning our medicine-chest."
"Indeed!" replied Dr. Germiny, "a thorough knowledge of bacteriology is the groundwork of therapeutics. It is practically admitted that every ailment, with the exception of mechanical injuries, is the direct result of a specific germ; and even in accidents and simple fractures, no matter what may be the nature of the bruise, a micro-organism soon announces its presence, so that if not the parent, it is the inseparable companion, in fact the shadow, of disease. Now, though not the first cause in this instance, it has been indubitably proved, that much of the effect, the fever and pain, are produced and continued by the active, omnipresent, sleepless sperm. Either kill the micrococcus or heal the wound, and you are free from both. It being, therefore, granted that the ills of life are in the air, we have but to find the peculiar nature of the case in hand, its habits, tastes, and constitution, in order to destroy it. Impoverish the soil on which it thrives, before its arrival, if you can foresee the nature of the inoculation to which you will be exposed, by a dilute solution of itself, and supply it only with what it particularly dislikes. For an already established tubercle requiring rapid action of the blood, such as may well exist among the birds and vertebrates of Jupiter and Saturn, I suggest a hypodermic rattlesnake injection, while hydrocyanic acid and tarantula saliva may also come in well. The combinations that so long destroyed us have already become our panacea."
"I see you have these poisons at your fingers' ends," said Ayrault, "and we shall feel the utmost confidence in the remedies and directions you prescribe."
They found that, in addition to their medicine-chest, they would have to make room for the following articles, and also many more: six shot-guns (three double-barrel 12-bores, three magazine 10-bores,) three rifles, three revolvers; a large supply of ammunition (explosive and solid balls), hunting-knives, fishing-tackle, compass, sextant, geometrical instruments, canned food for forty days, appliance for renewing air, clothing, rubber boots, apergetic apparatus, protection-wires, aneroid barometer, and kodaks.
At last the preparations were completed, and it was arranged that the Callisto should begin its journey at eleven o'clock A. M., December 21st--the northern hemisphere's shortest day.
Though six months' operations could hardly be expected to have produced much change in the inclination of the earth's axis, the autumn held on wonderfully, and December was pronounced very mild. Fully a million people were in and about Van Cortlandt Park hours before the time announced for the start, and those near looked inquiringly at the trim little air-ship, that, having done well on the trial trip, rested on her longitudinal and transverse keels, with a battery of chemicals alongside, to make sure of a full power supply.
The President and his Cabinet--including, of course, the shining lights of the State and Navy Departments--came from Washington. These, together with Mr. and Mrs. Preston, and a number of people with passes, occupied seats arranged at the sides of the platform; while sightseers and scientists assembled from every part of the world.
"There's a ship for you!" said Secretary Stillman to the Secretary of the Navy. "She'll not have to be dry-docked for barnacles, neither will the least breeze make the passengers sick." "That's all you landlubbers think of," replied Deepwaters. "I remember one of the kings over in Europe said to me, as he introduced me to the queen: 'Your Secretary of State is a great man, but why does he always part his hair in the middle?'
"'So that it shall not turn his head,' I replied.
"'But with so gallant and handsome an officer as you to lean upon,' he answered, 'I should think he could look down on all the world.' Whereupon I asked him what he'd take to drink."
"Your apology is accepted," replied Secretary Stillman.
Cortlandt also came from Washington, where, as chief of the Government's Expert Examiners Board, he had temporary quarters. Bearwarden sailed over the spectators' heads in one of the Terrestrial Axis Straightening Company's flying machines, while Ayrault, to avoid the crowd, had come to the Callisto early, and was showing the interior arrangements to Sylvia, who had accompanied him. She was somewhat piqued because at the last moment he had not absolutely insisted on carrying her off, or offered, if necessary, to displace his presidential and Doctor-of-Laws friends in order to make room.
"You will have an ideal trip," she said, looking over some astronomical star-charts and photographic maps of Jupiter and Saturn that lay on the table, with a pair of compasses, "and I hope you won't lose your way."
"I shall need no compass to find my way back," replied Ayrault, "if I ever succeed in leaving this planet; neither will star-charts be necessary, for you will be a magnet stronger than any compass, and, compared with my star, all others are dim."
"You should write a book," said Sylvia, "and put some of those things in it." She was wearing a bunch of forget-me-nots and violets that she had cut from a small flower-garden of potted plants Ayrault had sent her, which she had placed in her father's conservatory.
At this moment the small chime clock set in the Callisto's wood-work rang out quarter to eleven. As the sounds died away, Sylvia became very pale, and began to regret in her womanly way that she had allowed her hero to attempt this experiment.
"Oh," she said, clinging to his arm, "it was very wrong of me to let you begin this. I was so dazzled by the splendour of your scheme when I heard it, and so anxious that you should have the glory of being the first to surpass Columbus, that I did not realize the full meaning. I thought, also, you seemed rather ready to leave me," she added gently, "and so said little; you do not know how it almost breaks my heart now that I am about to lose you. It was quixotic to let you undertake this journey."
"An undertaker would have given me his kind offices for one even longer, had I remained here," replied Ayrault. "I cannot live in this humdrum world without you. The most sustained excitement cannot even palliate what seems to me like unrequited love."
"O Dick!" she exclaimed, giving him a reproachful glance, "you mustn't say that. You know you have often told me my reason for staying and taking my degree was good. My lot will be very much harder than yours, for you will forget me in the excitement of discovery and adventure; but I--what can I do in the midst of all the old associations?"
"Never mind, sweetheart," he said, kissing her hand, "I have seemed on the verge of despair all the time."
Seeing that their separation must shortly begin, Ayrault tried to assume a cheerful look; but as Sylvia turned her eyes away they were suspiciously moist.
Just one minute before the starting-time Ayrault took Sylvia back to her mother, and, after pressing her hand and having one last long look into her--or, as he considered them, HIS--deep-sea eyes, he returned to the Callisto, and was standing at the foot of the telescopic aluminum ladder when his friends arrived. As all baggage and impedimenta had been sent aboard and properly stowed the day before, the travellers had not to do but climb to and enter by the second-story window. It distressed Bearwarden that the north pole's exact declination on the 21st day of December, when the axis was most inclined, could not be figured out by the hour at which they were to start, so as to show what change, if any, had already been brought about, but the astronomers were working industriously, and promised that, if it were finished by midnight, they would telegraph the result into space by flash-light code.
Raising his hat to his fiancee and his prospective parents-in-law, Ayrault followed them up. To draw in and fold the ladder was but the work of a moment. As the clocks in the neighbouring steeples began to strike eleven, Ayrault touched the switch that would correspond to the throttle of an engine, and the motors began to work at rapidly increasing speed. Slowly the Callisto left her resting-place as a Galatea might her pedestal, only, instead of coming down, she rose still higher.
A large American flag hanging from the window, which, as they started, fluttered as in a southern zephyr, soon began to flap as in a stiff breeze as the car's speed increased. With a final wave, at which a battery of twenty-one field-pieces made the air ring with a salute, and the multitude raised a mighty cheer, they drew it in and closed the window, sealing it hermetically in order to keep in the air that, had an opening remained, would soon have become rarefied.
