And so Hobson had not been mistaken about the point of rupture. It was the isthmus which had yielded in the shock of the earthquake. Not a trace was to be seen of the American continent, not a single cliff, even the volcano on the west had disappeared. Nothing but the sea everywhere.
The island on this side ended in a cape, coming to an almost sharp point, and it was evident that the substratum of ice, fretted by the warmer waters of the current and exposed to all the fury of the elements, must rapidly dissolve.
The explorers resumed their march, following the course of the fracture, which ran from west to east in an almost straight line. Its edges were not jagged or broken, but clear cut, as if the division had been made with a sharp instrument, and here and there the conformation of the soil could be easily examined. The banks- half ice, half sand and earth-rose some ten feet from the water. They were perfectly perpendicular, without the slightest slope, and in some places there were traces of recent landslips. Sergeant Long pointed to several small blocks of ice floating in the offing, and rapidly melting, which had evidently been broken off from their island. The action of the warm surf would, of course, soon eat away the new coast-line, which time had not yet clothed with a kind of cement of snow and sand, such as covered the rest of the beach, and altogether the state of things was very far from reassuring.
Before taking any rest, Mrs Barnett, Hobson, and Long, were anxious to finish their examination of the southern edge of the island. There would be plenty of daylight, for the sun would not set until eleven o'clock P.M. The briliant orb of day was slowly advancing along the western horizon, and its oblique rays cast long shadows of themselves before the explorers, who conversed at intervals after long silent pauses, during which they gazed at the sea and thought of the dark future before them.
Hobson intended to encamp for the night at Washburn Bay. When there eighteen miles would have been traversed, and, if he were not mistaken, half his circular journey would be accomplished. After a few hours' repose he meant to return to Fort Hope along the western coast.
No fresh incident marked the exploration of the short distance between Walruses' Bay and Washburn Bay, and at seven o'clock in the evening the spot chosen for the encampment was reached. A similar change had taken place here. Of Washburn Bay, nothing remained but the curve formed by the coast-line of the island, and which was once its northern boundary. It stretched away without a break for seven miles to the cape they had named Cape Michael. This side of the island did not appear to have suffered at all in consequence of the rupture. The thickets of pine and birch, massed a little behind the cape, were in their fullest beauty at this time of year, and a good many furred animals were disporting themselves on the plain.
A halt was made at Washburn Bay, and the explorers were able to enjoy an extended view on the south, although they could not see any great distance on the north. The sun was so low on the horizon, that its rays were intercepted by the rising ground on the west, and did not reach the little bay. It was not, however, yet night, nor could it be called twilight, as the sun had not set.
"Lieutenant," said Long, "if by some miracle a bell were now to ring, what do you suppose it would mean?"
"That it was supper-time," replied Hobson. "Don't you agree with me, Mrs Barnett?"
"Indeed I do," replied the lady addressed, "and as our cloth is spread for us, let us sit down. This moss, although slightly worn, will suit us admirably, and was evidently intended for us by Providence."
The bag of provisions was opened; some salt meat, a hare pate from Mrs Joliffe's larder, with a few biscuits, formed their frugal supper.
The meal was quickly over, and Hobson returned to the southwest angle of the island, whilst Mrs Barnett rested at the foot of a low fir tree, and Sergeant Long made ready the night quarters.
The Lieutenant was anxious to examine the piece of ice which formed the island, to ascertain, if possible, something of its structure. A little bank, produced by a landslip, enabled him to step down to the level of the sea, and from there he was able to look closely at the steep wall which formed the coast. Where he stood the soil rose scarcely three feet above the water. The upper part consisted of a thin layer of earth and sand mixed with crushed shells; and the lower of hard, compact, and, if we may so express it, "metallic" ice, strong enough to support the upper soil of the island.
This layer of ice was not more than one foot above the sea-level. In consequence of the recent fracture, it was easy to see the regular disposition of the sheets of ice piled up horizontally, and which had evidently been produced by successive frosts in comparatively quieter waters.
We know that freezing commences on the surface of liquids, and as the cold increases, the thickness of the crust becomes greater, the solidification proceeding from the top downwards. That at least is the case in waters that are at rest; it has, however, been observed that the very reverse is the case in running waters-the ice forming at the bottom, and subsequently rising to the surface.
It was evident, then, that the floe which formed the foundation of Victoria Island had been formed in calm waters on the shores of the North American continent. The freezing had evidently commenced on the surface, and the thaw would begin at the bottom, according to a well-known law; so that the ice-field would gradually decrease in weight as it became thawed by the warmer waters through which it was passing, and the general level of the island would sink in proportion.
This was the great danger.
As we have just stated, Hobson noticed that the solid ice, the ice-field properly so called, was only about one foot above the sea-level! We know that four-fifths of a floating mass of ice are always submerged. For one foot of an iceberg or ice-field above the water, there are four below it. It must, however, be remarked that the density, or rather specific weight of floating ice, varies considerably according to its mode of formation or origin. The ice-masses which proceed from sea water, porous, opaque, and tinged with blue or green, according as they are struck by the rays of the sun, are lighter than ice formed from fresh water. All things considered, and making due allowance for the weight of the mineral and vegetable layer above the ice. Hobson concluded it to be about four or five feet thick below the sea-level. The different declivities of the island, the little hills and rising ground, would of course only affect the upper soil, and it might reasonably be supposed that the wandering island was not immersed more than five feet.
This made Hobson very anxious. Only five feet! Setting aside the causes of dissolution to which the ice-field might be subjected, would not the slightest shock cause a rupture of the surface? Might not a rough sea or a gale of wind cause a dislocation of the ice-field, which would lead to its breaking up into small portions, and to its final decomposition? Oh for the speedy arrival of the winter, with its bitter cold! Would that the column of mercury were frozen in its cistern! Nothing but the rigour of an Arctic winter could consolidate and thicken the foundation of their island, and establish a means of communication between it and the continent.
Hobson returned to the halting-place little cheered by his discoveries, and found Long busy making arrangements for the night; for he had no idea of sleeping beneath the open sky, although Mrs Barnett declared herself quite ready to do so. He told the Lieutenant that he intended to dig a hole in the ice big enough to hold three persons-in fact to make a kind of snow-hut, in which they would be protected from the cold night air.
"In the land of the Esquimaux," he said, "nothing is wiser than to do as the Esquimaux do."
Hobson approved, but advised the Sergeant not to dig too deeply, as the ice was not more than five feet thick.
Long set to work. With the aid of his hatchet and ice-chisel he had soon cleared away the earth, and hollowed out a kind of passage sloping gently down to the crust of ice.
He next attacked the brittle mass, which had been covered over with sand and earth for so many centuries. It would not take more than an hour to hollow out a subterranean retreat, or rather a burrow with walls of ice, which would keep in the heat, and therefore serve well for a resting-place during the short night.
Whilst Long was working away like a white ant, Hobson communicated the result of his observations to Mrs Barnett. He did not disguise from her that the construction of Victoria Island rendered him very uneasy. He felt sure that the thinness of the ice would lead to the opening of ravines on the surface before long; where, it would be impossible to foresee, and of course it would be equally impossible to prevent them. The wandering Island might at any moment settle down in consequence of a change in its specific gravity, or break up into more or less numerous islets, the duration of which must necessarily be ephemeral. He judged, therefore, that it would be best for the members of the colony to keep together as much as possible, and not to leave the fort, that they might all share the same chances.
Hobson was proceeding further to unfold his views when cries for help were heard.
Mrs Barnett started to her feet, and both looked round in every direction, but nothing was to be seen.
The cries were now redoubled, and Hobson exclaimed-
"The Sergeant! the Sergeant!"
And followed by Mrs Barnett, he rushed towards the burrow, and he had scarcely reached the opening of the snow-house before he saw Sergeant Long clutching with both hands at his knife, which he had stuck in the wall of ice, and calling out loudly, although with the most perfect self-possession.
His head and arms alone were visible. Whilst he was digging, the ice had given way suddenly beneath him, and he was plunged into water up to his waist.
Hobson merely said-
"Keep hold!"
And creeping through the passage, he was soon at the edge of the hole. The poor Sergeant seized his hand, and he was soon rescued from his perilous position.
"Good God! Sergeant!" exclaimed Mrs Barnett; "what has happened?"
"Nothing," replied Long, shaking himself like a wet spaniel, "except that the ice gave way under me, and I took a compulsory bath."
"You forgot what I told you about not digging too deeply, then," said Hobson.
"Beg pardon, sir; I hadn't cut through fifteen inches of the ice, and I expect there was a kind of cavern where I was working-the ice did not touch the water. It was just like going through a ceiling. If I hadn't been able to hang on by my knife, I should have slipped under the island like a fool, and that would have been a pity, wouldn't it, madam?"
"A very great pity, my brave fellow," said Mrs Barnett, pressing his hand.
Long's explanation was correct; for some reason or another-most likely from an accumulation of air-the ice had formed a kind of vault above the water, and of course it soon gave way under the weight of the Sergeant and the blows of his chisel.
The same thing might happen in other parts of the island, which was anything but reassuring. Where could they be certain of treading on firm ground? Might not the earth give way beneath their feet at any minute? What heart, however brave, would not have sunk at the thought of the thin partition between them and the awful gulf of the ocean?
Sergeant Long, however, thought but little of his bath, and was ready to begin mining in some other place. This Mrs Barnett would not allow. A night in the open air would do her no harm; the shelter of the coppice near would be protection enough for them all; and Sergeant Long was obliged to submit.
The camp was, therefore, moved back some thirty yards from the beach, to a rising ground on which grew a few clumps of pines and willows which could scarcely be called a wood. Towards ten o'clock the disc of the sun began to dip below the horizon, and before it disappeared for the few hours of the night a crackling fire of dead branches was blazing at the camp.
Long had now a fine opportunity of drying his legs, of which he gladly availed himself. He and Hobson talked together earnestly until twilight set in, and Mrs Barnett occasionally joined in the conversation, doing the best she could to cheer the disheartened Lieutenant. The sky was bright with stars, and the holy influence of the night could not fail to calm his troubled spirit. The wind murmured softly amongst the pines; even the sea appeared to be wrapt in slumber, its bosom slightly heaving with the swell, which died away upon the beach with a faint rippling sound. All creation was hushed, not even the wail of a sea bird broke upon the ear, the crisp crackling of the dead branches was exchanged for a steady flame, and nothing but the voices of the wanderers broke the sublime, the awful silence of the night.
"Who would imagine," said Mrs Barnett, "that we were floating on the surface of the ocean! It really requires an effort to realise it, for the sea which is carrying us along in its fatal grasp appears to be absolutely motionless!"
"Yes, madam," replied Hobson;" and if the floor of our carriage were solid, if I did not know that sooner or later the keel of our boat will be missing, that some day its hull will burst open, and finally, if I knew where we are going, I should rather enjoy floating on the ocean like this."
"Well, Lieutenant," rejoined Mrs Barnett, "could there be a pleasanter mode of travelling than ours? We feel no motion. Our island has exactly the same speed as the current which is bearing it away. Is it not like a balloon voyage in the air? What could be more delightful than advancing with one's house, garden, park, &c.? A wandering island, with a solid insubmersible foundation, would really be the most comfortable and wonderful conveyance that could possibly be imagined. I have heard of hanging gardens. Perhaps some day floating parks will be invented which will carry us all over the globe! Their size will render them insensible to the action of the waves, they will have nothing to fear from storms, and perhaps with a favourable wind they might be guided by means of immense sails! What marvels of vegetation would be spread before the eyes of the passengers when they passed from temperate to torrid zones! With skilful pilots, well acquainted with the currents, it might be possible to remain in one latitude, and enjoy a perpetual spring."
Hobson could not help smiling at Mrs Barnett's fancies. The brave woman ran on with such an easy flow of words, she talked with as little effort as Victoria Island moved. And was she not right? It would have been a very pleasant mode of travelling if there had been no danger of their conveyance melting and being swallowed up by the sea.
The night passed on, and the explorers slept a few hours. At daybreak they breakfasted, and thoroughly enjoyed their meal. The warmth and rest had refreshed them, and they resumed their journey at about six o'clock A.M.
From Cape Michael to the former Port Barnett the coast ran in an almost straight line from south to north for about eleven miles. There was nothing worthy of note about it; the shores were low and pretty even all the way, and seemed to have suffered no alteration since the breaking of the isthmus. Long, in obedience to the Lieutenant, made bench marks along the beach, that any future change might be easily noted.
Hobson was naturally anxious to get back to Fort Hope the same day, and Mrs Barnett was also eager to return to her friends. It was of course desirable under the circumstances that the commanding officer should not be long absent from the fort
All haste was therefore made, and by taking a short cut they arrived at noon at the little promontory which formerly protected Port Barnett from the east winds.
It was not more than eight miles from this point to Fort Hope, and before four o'clock P.M the shouts of Corporal Joliffe welcomed their return to the factory.
Hobson's first care on his return to the fort, was to make inquiries of Thomas Black as to the situation of the little colony. No change had taken place for the last twenty-four hours, but, as subsequently appeared, the island had floated one degree of latitude further south, whilst still retaining its motion towards the west. It was now at the same distance from the equator as Icy Cape, a little promontory of western Alaska, and two hundred miles from the American coast. The speed of the current seemed to be less here than in the eastern part of the Arctic Ocean, but the island continued to advance, and, much to Hobson's annoyance, towards the dreaded Behring Strait. It was now only the 24th July, and a current of average speed would carry it in another month through the strait and into the heated waves of the Pacific, where it would melt "like a lump of sugar in a glass of water."
Mrs Barnett acquainted Madge with the result of the exploration of the island. She explained to her the arrangement of the layers of earth and ice at the part where the isthmus had been broken off; told her that the thickness of the ice below the sea level was estimated at five feet; related the accident to Sergeant Long-in short, she made her fully understand the reasons there were to fear the breaking up or sinking of the ice field.
The rest of the colony had, however, no suspicion of the truth; a feeling of perfect security prevailed. It never occurred to any of the brave fellows that Fort Hope was floating above an awful abyss, and that the lives of all its inhabitants were in danger. All were in good health, the weather was fine, and the climate pleasant and bracing. The baby Michael got on wonderfully; he was beginning to toddle about between the house and the palisade; and Corporal Joliffe, who was extremely fond of him, was already beginning to teach him to hold a gun, and to understand the first duties of a soldier. Oh, if Mrs Joliffe would but present him with such a son! but, alas! the blessing of children, for which he and his wife prayed every day, was as yet denied to them.
Meanwhile the soldiers had plenty to do.
Mac-Nab and his men-Petersen, Belcher, Garry, Pond, and Hope-worked zealously at the construction of a boat, a difficult task, likely to occupy them for several months. But as their vessel would be of no use until next year after the thaw, they neglected none of their duties at the factory on its account. Hobson let things go on as if the future of the factory were not compromised, and persevered in keeping the men in ignorance. This serious question was often discussed by the officer and his "staff," and Mrs Barnett and Madge differed from their chief on the subject. They thought it would be better to tell the whole truth; the men were brave and energetic, not likely to yield to despair, and the shock would not be great if they heard of it now, instead of only when their situation was so hopeless that it could not be concealed. But in spite of the justice of these remarks, Hobson would not yield, and he was supported by Sergeant Long. Perhaps, after all, they were right; they were both men of long experience, and knew the temper of their men.
And so the work of provisioning and strengthening the fort proceeded. The palisaded enceinte was repaired with new stakes, and made higher in many places, so that it really formed a very strong fortification. Mac-Nab also put into execution, with his chief's approval, a plan he had long had at heart. At the corners abutting on the lake he built two little pointed sentry-boxes, which completed the defences; and Corporal Joliffe anticipated with delight the time when he should be sent to relieve guard: he felt that they gave a military look to the buildings, and made them really imposing.
The palisade was now completely finished, and Mac-Nab, remembering the sufferings of the last winter, built a new wood shed close up against the house itself, with a door of communication inside, so that there would be no need to go outside at all. By this contrivance the fuel would always be ready to hand. On the left side of the house, opposite the shed, Mac-Nab constructed a large sleeping-room for the soldiers, so that the camp-bed could be removed from the common room. This room was also to be used for meals, and work. The three married couples had private rooms walled off, so that the large house was relieved of them as well as of all the other soldiers. A magazine for furs only was also erected behind the house near the powder-magazine, leaving the loft free for stores; and the rafters and ribs of the latter were bound with iron cramps, that they might be able to resist all attacks. Mac-Nab also intended to build a little wooden chapel, which had been included in Hobson's original plan of the factory; but its erection was put off until the next summer.
With what eager interest would the Lieutenant have once watched the progress of his establishment! Had he been building on firm ground, with what delight would he have watched the houses, sheds, and magazines rising around him! He remembered the scheme of crowning Cape Bathurst with a redoubt for the protection of Fort Hope with a sigh. The very name of the factory, "Fort Hope," made his heart sink within him; for should it not more truly be called "Fort Despair?"
These various works took up the whole summer, and there was no time for ennui. The construction of the boat proceeded rapidly. Mac-Nab meant it to be of about thirty tons measurement, which would make it large enough to carry some twenty passengers several hundred miles in the fine season. The carpenter had been fortunate enough to find some bent pieces of wood, so that he was able quickly to form the first ribs of the vessel, and soon the stern and sternpost, fixed to the keel, were upon the dockyard at the foot of Cape Bathurst.
Whilst the carpenters were busy with hatchets, saws, and adzes, the hunters were eagerly hunting the reindeer and Polar hares, which abounded near the fort. The Lieutenant, however, told Marbre and Sabine not to go far away, stating as a reason, that until the buildings were completed he did not wish to attract the notice of rivals. The truth was, he did not wish the changes which had taken place to be noticed.
One day Marbre inquired if it was not now time to go to Walruses' Bay, and get a fresh supply of morse-oil for burning, and Hobson replied rather hastily-
"No, Marbre; it would be useless."
The Lieutenant knew only too well that Walruses' Bay was two hundred miles away, and that there were no morses to be hunted on the island.
It must not be supposed that Hobson considered the situation desperate even now. He often assured Mrs Barnett, Madge, and Long that he was convinced the island would hold together until the bitter cold of winter should thicken its foundation and arrest its course at one and the same time.
After his journey of discovery, Hobson estimated exactly the area of his new dominions. The island measured more than forty miles round, from which its superficial area[r] would appear to be about one hundred and forty miles at the least. By way of comparison, we may say that Victoria Island was rather larger than St Helena, and its area was about the same as that of Paris within the line of fortifications. If then it should break up into fragments, the separate parts might still be of sufficient size to be habitable for some time.
When Mrs Barnett expressed her surprise that a floating ice-field could be so large, Hobson replied by reminding her of the observations of Arctic navigators. Parry, Penny, and Franklin had met with ice-fields in the Polar seas one hundred miles long and fifty broad. Captain Kellet abandoned his boat on an ice-field measuring at least three hundred square miles, and what was Victoria Island compared to it?
Its size was, however, sufficient to justify a hope that it would resist the action of the warm currents until the cold weather set in. Hobson would not allow himself to doubt; his despair arose rather from the knowledge that the fruit of all his cares, anxieties, and dangers must eventually be swallowed up by the deep, and it was no wonder that he could take no interest in the works that were going on.
Mrs Barnett kept up a good heart through it all; she encouraged her comrades in their work, and took her share in it, as if she had still a future to look forward to. Seeing what an interest Mrs Joliffe took in her plants, she joined her every day in the garden. There was now a fine crop of sorrel and scurvy-grass-thanks to the Corporal's unwearying exertions to keep off the birds of every kind, which congregated by hundreds.
The taming of the reindeer had been quite successful; there were now a good many young, and little Michael had been partly brought up on the milk of the mothers. There were now some thirty head in the herd which grazed near the fort, and a supply of the herbage on which they feed was dried and laid up for the winter. These useful animals, which are easily domesticated, were already quite familiar with all the colonists, and did not go far from the enceinte. Some of them were used in sledges to carry timber backwards and forwards. A good many reindeer, still wild, now fell into the trap half way between the fort and Port Barnett. It will be remembered that a large bear was once taken in it; but nothing of the kind occurred this season-none fell victims but the reindeer, whose flesh was salted and laid by for future use. Twenty at least were taken, which in the ordinary course of things would have gone down to the south in the winter.
One day, however, the reindeer-trap suddenly became useless in consequence of the conformation of the soil. After visiting it as usual, the hunter Marbre approached Hobson, and said to him in a significant tone--
"I have just paid my daily visit to the reindeer-trap, sir."
"Well, Marbre, I hope you have been as successful to-day as yesterday, and have caught a couple of reindeer," replied Hobson.
"No, sir, no," replied Marbre, with some embarrassment.
"Your trap has not yielded its ordinary contingent then?"
"No, sir; and if any animal had fallen in, it would certainly have been drowned!"
"Drowned!" cried the Lieutenant, looking at the hunter with an anxious expression.
"Yes, sir," replied Marbre, looking attentively at his superior, "the pit is full of water."
"Ah!" said Hobson, in the tone of a man who attached no importance to that, "you know your pit was partly hollowed out of ice; its walls have melted with the heat of the sun, and then "--
"Beg pardon for interrupting you, sir," said Marbre; "but the water cannot have been produced by the melting of ice."
"Why not, Marbre?" "Because if it came from ice it would be sweet, as you explained to me once before. Now the water in our pit is salt!"
Master of himself as he was, Hobson could not help changing countenance slightly, and he had not a word to say.
"Besides," added Marbre, "I wanted to sound the trench, to see how deep the water was, and to my great surprise, I can tell you, I could not find the bottom."
"Well, Marbre," replied Hobson hastily, "there is nothing so wonderful in that. Some fracture of the soil has established a communication between the sea and the trap. So don't be uneasy about it, my brave fellow, but leave the trap alone for the present, and be content with setting snares near the fort."
Marbre touched his cap respectfully, and turned on his heel, but not before he had given his chief a searching glance.
Hobson remained very thoughtful for a few moments. Marbre's tidings were of grave importance. It was evident that the bottom of the trench, gradually melted by the warm waters of the sea, had given way.
Hobson at once called the Sergeant, and having acquainted him with the incident, they went together, unnoticed by their companions, to the beach at the foot of Cape Bathurst, where they had made the bench-marks.
They examined them carefully, and found that since they last did so, the floating island had sunk six inches.
"We are sinking gradually," murmured Sergeant Long. "The ice is wearing away."
"Oh for the winter! the winter!" cried Hobson, stamping his foot upon the ground.
But as yet, alas! there was no sign of the approach of the cold season. The thermometer maintained a mean height of 59? Fahrenheit, and during the few hours of the night the column of mercury scarcely went down three degrees.
Preparations for the approaching winter went on apace, and there was really nothing wanting to Fort Hope, although it had not been revictualled by Captain Craventy's detachment. The long hours of the Arctic night might be awaited in perfect security. The stores were of course carefully husbanded. There still remained plenty of spirits, only small quantities having been consumed; and there was a good stock of biscuits, which, once gone, could not be replaced. Fresh venison and salt meat were to be had in abundance, and with some antiscorbutic vegetables, the diet was most healthy; and all the members of the little colony were well.
A good deal of timber was cut in the woods clothing the eastern slopes of Lake Barnett. Many were the birch-trees, pines, and firs which fell beneath the axe of Mac-Nab, and were dragged to the house by the tamed reindeer. The carpenter did not spare the little forest, although he cut his wood judiciously; for he never dreamt that timber might fail him, imagining, as he did, Victoria Island to be a peninsula, and knowing the districts near Cape Michael to be rich in different species of trees.
Many a time did the unconscious carpenter congratulate his Lieutenant on having chosen a spot so favoured by Heaven. Woods, game, furred animals, a lagoon teeming with fish, plenty of herbs for the animals, and, as Corporal Joliffe would have added, double pay for the men. Was not Cape Bathurst a corner of a privileged land, the like of which was not to be found in the whole Arctic regions? Truly Hobson was a favourite of Heaven, and ought to return thanks to Providence every day for the discovery of this unique spot.
Ah, Mac-Nab, you little knew how you wrung the heart of your master when you talked in that strain!
The manufacture of winter garments was not neglected in the factory. Mrs Barnett, Madge, Mrs Mac-Nab, Mrs Rae, and Mrs Joliffe-when she could leave her fires-were alike indefatigable. Mrs Barnett knew that they would all have to leave the fort in the depth of winter, and was determined that every one should be warmly clothed. They would have to face the bitterest cold for a good many days during the Polar night, if Victoria Island should halt far from the continent. Boots and clothes ought indeed to be strong and well made, for crossing some hundreds of miles under such circumstances. Mrs Barnett and Madge devoted all their energies to the matter in hand, and the furs, which they knew it would be impossible to save, were turned to good account. They were used double, so that the soft hair was both inside and outside of the clothes; and when wearing them, the whole party would be as richly attired as the grandest princesses, or the most wealthy ladies. Those not in the secret were rather surprised at the free use made of the Company's property; but Hobson's authority was not to be questioned, and really martens, polecats, musk-rats, beavers, and foxes multiplied with such rapidity near the fort, that all the furs used could easily be replaced by a few shots, or the setting of a few traps; and when Mrs Mac-Nab saw the beautiful ermine coat which had been made for her baby, her delight was unbounded, and she no longer wondered at anything.
So passed the days until the middle of the month of August. The weather continued fine, and any mists which gathered on the horizon were quickly dispersed by the sunbeams.
Every day Hobson took the bearings, taking care, however, to go some distance from the fort, that suspicions might not be aroused, and he also visited different parts of the island, and was reassured by finding that no important changes appeared to be taking place.
On the 16th August Victoria Island was situated in 167? 27' west longitude, and 70? 49' north latitude. It had, therefore, drifted slightly to the south, but without getting any nearer to the American coast, which curved considerably.
The distance traversed by the island since the fracture of the isthmus, or rather since the last thaw, could not be less than eleven or twelve hundred miles to the west.
But what was this distance compared to the vast extent of the ocean? Had not boats been known to be drifted several thousands of miles by currents? Was not this the case with the English shipResolute, the American brigAdvance, and with theFox, all of which were carried along upon ice-fields until the winter arrested their advance?
From the 17th to the 20th August the weather continued fine, and the temperature moderate. The mists on the horizon were not resolved into clouds, and altogether the weather was exceptionally beautiful for such an elevated position. It will be readily understood, however, that Hobson could take no pleasure in the fineness of the climate.
On the 21st August, however, the barometer gave notice of an approaching change. The column of mercury suddenly fell considerably, the sun was completely hidden at the moment of culmination, and Hobson was unable to take his bearings.
The next day the wind changed and blew strongly from the north-west, torrents of rain falling at intervals. Meanwhile, however, the temperature did not change to any sensible extent, the thermometer remaining at 54? Fahrenheit.
Fortunately the proposed works were now all finished, and MacNab had completed the carcass of his boat, which was planked and ribbed. Hunting might now be neglected a little, as the stores were complete, which was fortunate, for the weather became very bad. The wind was high, the rain incessant, and thick fogs rendered it impossible to go beyond the enceinte of the fort.
"What do you think of this change in the weather, Lieutenant?" inquired Mrs Barnett on the morning of the 27th August; "might it not be in our favour?"
"I should not like to be sure of it, madam," replied Hobson; "but anything is better for us than the magnificent weather we have lately had, during which the sun made the waters warmer and warmer. Then, too, the wind from the north-west is so very strong that it may perhaps drive us nearer to the American continent."
"Unfortunately," observed Long, "we can't take our bearings every day now. It's impossible to see either sun, moon, or stars in this fog. Fancy attempting to take an altitude now!"
"We shall see well enough to recognise America, if we get anywhere near it," said Mrs Barnett. "Whatever land we approach will be welcome. It will most likely be some part of Russian America-probably Western Alaska."
"You are right, madam," said Hobson; "for, unfortunately, in the whole Arctic Ocean there is not an island, an islet, or even a rock to which we could fasten our vessel!"
"Well," rejoined Mrs Barnett, "why should not our conveyance take us straight to the coasts of Asia? Might not the currents carry us past the opening of Bearing Strait and land us on the shores of Siberia?"
"No, madam, no," replied Hobson; "our ice-field would soon meet the Kamtchatka current, and be carried by it to the northwest. It is more likely, however, that this wind will drive us towards the shores of Russian America."
"We must keep watch, then," said Mrs Barnett, "and ascertain our position as soon as possible."
"We shall indeed keep watch," replied Hobson, "although this fog is very much against us If we should be driven on to the coast, the shock will be felt even if we cannot see. Let's hope the island will not fall to pieces in this storm! That is at present our principal danger. Well, when it comes we shall see what there is to be done, and meanwhile we must wait patiently."
Of course this conversation was not held in the public room, where the soldiers and women worked together. It was in her own room, with the window looking out on the court, that Mrs Barnett received visitors. It was almost impossible to see indoors even in the daytime, and the wind could be heard rushing by outside like an avalanche. Fortunately, Cape Bathurst protected the house from the north-east winds, but the sand and earth from its summit were hurled down upon the roof with a noise like the pattering of hail. Mac-Nab began to feel fresh uneasiness about his chimneys, which it was absolutely necessary to keep in good order. With the roaring of the wind was mingled that of the sea, as its huge waves broke upon the beach. The storm had become a hurricane.
In spite of the fury of the gale, Hobson determined on the morning of the 28th of August to climb to the summit of Cape Bathurst, in order to examine the state of the horizon, the sea, and the sky. He therefore wrapped himself up, taking care to have nothing about him likely to give hold the wind, and set out.
He got to the foot of the cape without much difficulty. The sand and earth blinded him, it is true, but protected by the cliff he had not as yet actually faced the wind. The fatigue began when he attempted to climb the almost perpendicular sides of the promontory; but by clutching at the tufts of herbs with which they were covered, he managed to get to the top, but there the fury of the gale was such that he could neither remain standing nor seated; he was therefore forced to fling himself upon his face behind the little coppice and cling to some shrubs, only raising his head and shoulders above the ground.
The appearance of sea and sky was indeed terrible. The spray dashed over the Lieutenant's head, and half-a-mile from the cape water and clouds were confounded together in a thick mist. Low jagged rain-clouds were chased along the heavens with giddy rapidity, and heavy masses of vapour were piled upon the zenith. Every now and then an awful stillness fell upon the land, and the only sounds were the breaking of the surf upon the beach and the roaring of the angry billows; but then the tempest recommenced with redoubled fury, and Hobson felt the cape tremble to its foundations. Sometimes the rain poured down with such violence that it resembled grape-shot.
It was indeed a terrible hurricane from the very worst quarter of the heavens. This north-east wind might blow for a long time and cause all manner of havoc. Yet Hobson, who would generally have grieved over the destruction around him, did not complain,-on the contrary, he rejoiced; for if, as he hoped, the island held together, it must be driven to the south-west by this wind, so much more powerful than the currents. And the south-west meant land-hope-safety! Yes, for his own sake, and for that of all with him, he hoped that the hurricane would last until it had flung them upon the laud, no matter where. That which would have been fatal to a ship was the best thing that could happen to the floating island.
For a quarter of an hour Hobson remained crouching upon the ground, clutching at the shrubs like a drowning man at a spar, lashed by the wind, drenched by the rain and the spray, struggling to estimate all the chances of safety the storm might afford him. At the end of that time he let himself slide down the cape, and fought his way to Fort Hope.
Hobson's first care was to tell his comrades that the hurricane was not yet at its height, and that it would probably last a long time yet. He announced these tidings with the manner of one bringing good news, and every one looked at him in astonishment. Their chief officer really seemed to take a delight in the fury of the elements.
On the 30th Hobson again braved the tempest, not this time climbing the cape, but going down to the beach. What was his joy at noticing some long weeds floating on the top of the waves, of a kind which did not grow on Victoria Island. Christopher Columbus' delight was not greater when he saw the sea-weed which told him of the proximity of land.
The Lieutenant hurried back to the fort, and told Mrs Barnett and Sergeant Long of his discovery. He had a good mind to tell every one the whole truth now, but a strange presentiment kept him silent.
The occupants of the fort had plenty to amuse them in the long days of compulsory confinement. They went on improving the inside of the various buildings, and dug trenches in the court to carry away the rain-water. Mac-Nab, a hammer in one hand and a nail in the other, was always busy at a job in some corner or another, and nobody took much note of the tempest outside in the daytime; but at night it was impossible to sleep, the wind beat upon the buildings like a battering-ram; between the house and the cape sometimes whirled a huge waterspout of extraordinary dimensions; the planks cracked, the beams seemed about to separate, and there was danger of the whole structure tumbling down. Mac-Nab and his men lived in a state of perpetual dread, and had to be continually on the watch.
Meanwhile, Hobson was uneasy about the stability of the island itself, rather than that of the house upon it. The tempest became so violent, and the sea so rough, that there was really a danger of the dislocation of the ice-field. It seemed impossible for it to resist much longer, diminished as it was in thickness and subject to the perpetual action of the waves. It is true that its inhabitants did not feel any motion, on account of its vast extent, but it suffered from it none the less. The point at issue was simply:-Would the island last until it was flung upon the coast, or would it fall to pieces before it touched firm ground?
There could be no doubt that thus far it had resisted. As the Lieutenant explained to Mrs Barnett, had it already been broken, had the ice-field already divided into a number of islets, the occupants of the fort must have noticed it, for the different pieces would have been small enough to be affected by the motion of the sea, and the people on any one of them would have been pitched about like passengers on a boat. This was not the case, and in his daily observations Lieutenant Hobson had noticed no movement whatever, not so much as a trembling of the island, which appeared as firm and motionless as when it was still connected by its isthmus with the mainland.
But the breaking up, which had not yet taken place, might happen at any minute.
Hobson was most anxious to ascertain whether Victoria Island, driven by the north-west wind out of the current, had approached the continent. Everything, in fact, depended upon this, which was their last chance of safety. But without sun, moon, or stars, instruments were of course useless, as no observations could be taken, and the exact position of the island could not be determined. If, then, they were approaching the land, they would only know it when the land came in sight, and Hobson's only means of ascertaining anything in time to be of any service, was to get to the south of his dangerous dominions. The position of Victoria Island with regard to the cardinal points had not sensibly altered all the time. Cape Bathurst still pointed to the north, as it did when it was the advanced post of North America. It was, therefore, evident that if Victoria Island should come alongside of the continent, it would touch it with its southern side,-the communication would, in a word, be re-established by means of the broken isthmus; it was, therefore, imperative to ascertain what was going on in that direction.
Hobson determined to go to Cape Michael, however terrible the storm might be, but he meant to keep the real motive of his reconnaissance a secret from his companions. Sergeant Long was to accompany him.
About four o'clock P.M., on the 31st August, Hobson sent for the Sergeant in his own room, that they might arrange together for all eventualities.
"Sergeant Long," he began, "it is necessary that we should, without delay, ascertain the position of Victoria Island, and above all whether this wind has, as I hope, driven it near to the American continent."
"I quite agree with you, sir," replied Long, "and the sooner we find out the better"
"But it will necessitate our going down to the south of the island."
"I am ready, sir."
"I know, Sergeant, that you are always ready to do your duty, but you will not go alone. Two of us ought to go, that we may be able to let our comrades know if any land is in sight; and besides I must see for myself ... we will go together."
"When you like, Lieutenant, just when you think best."
"We will start this evening at nine o'clock, when everybody else has gone to bed"
"Yes, they would all want to come with us," said Long, "and they must not know why we go so far from the factory."
"No, they must not know," replied Hobson, "and if I can, I will keep the knowledge of our awful situation from them until the end."
"It is agreed then, sir?"
"Yes. You will take a tinder-box and some touchwood [Footnote: A fungus used as tinder (Polyporous igniarius).] with you, so that we can make a signal if necessary-if land is in sight in the south, for instance"
"Yes, sir."
"We shall have a rough journey, Sergeant."
"What does that matter, sir, but by the way-the lady?"
"I don't think I shall tell her. She would want to go with us."
"And she could not," said the Sergeant, "a woman could not battle with such a gale. Just see how its fury is increasing at this moment!"
Indeed the house was rocking to such an extent that it seemed likely to be torn from its foundations.
"No," said Hobson, "courageous as she is, she could not, she ought not to accompany us. But on second thought, it will be best to tell her of our project. She ought to know in case any accident should befall us"
"Yes," replied Long, "we ought not to keep anything from her, and if we do not come back"....
"At nine o'clock then, Sergeant."
"At nine o'clock."
And with a military salute Sergeant Long retired.
A few minutes later Hobson was telling Mrs Barnett of his scheme. As he expected the brave woman insisted on accompanying him, and was quite ready to face the tempest. Hobson did not dissuade her by dwelling on the dangers of the expedition, he merely said that her presence was necessary at the fort during his absence, and that her remaining would set his mind at ease. If any accident happened to him it would be a comfort to know that she would take his place.
Mrs Barnett understood and said no more about going; but only urged Hobson not to risk himself unnecessarily. To remember that he was the chief officer, that his life was not his own, but necessary to the safety of all. The Lieutenant promised to be as prudent as possible; but added that the examination of the south of the island must be made at once, and he would make it. The next day Mrs Barnett merely told her companions that the Lieutenant and the Sergeant had gone to make a final reconnaissance before the winter set in.
