The Mississippi is the only river in North America, which, for grandeur and commodiousness of navigation, comes in competition with the St. Lawrence, or with that river which runs from Lake Ontario to the ocean. If, however, we consider that immense body of water that flows from Lake Winnipeg through the Lake of the Woods, Lake Superior, &c., down to the sea, as one entire stream, and, of course, as a continuation of the St. Lawrence, it must be allowed to be a very superior river to the Mississippi in every point of view; and we may certainly consider it as one stream with as much reason as we look upon that as one river which flows from Lake Ontario to the sea; for, before it meets the ocean, it passes through four large lakes, not, indeed, to be compared with those of Erie or Superior in size, but they are independent lakes, notwithstanding, as much as any of the others. The Mississippi is principally to be admired for the evenness of its current, and the prodigious length of way it is navigable without any interruption for bateaux of a very large burden, but in many respects it is a very inferior river to the St. Lawrence, properly so called. The Mississippi, at its mouth, is not twenty miles broad, and the navigation is there so obstructed by banks or bars that a vessel drawing more than twelve feet water can not ascend it without very imminent danger. Fresh bars are formed or the old bars are enlarged every year, and it is said that unless some steps are taken to prevent the lodgments of the trees annually brought down at the time of the inundation, the navigation may in a few years be still more obstructed than it is at present. The River St. Lawrence, however, on the contrary, is no less than ninety miles wide at its mouth, and it is navigable for ships of the line as far as Quebec, a distance of 400 miles from the sea. The channel, also, instead of having been impaired by time, is found to be considerably better now than when the river was first discovered, and there is reason to imagine that it will improve still more in process of time, as the clear water that flows from Lake Ontario comes down with such impetuosity during the floods in the spring of the year as frequently to remove banks of gravel and loose stones in the river, and thus to deepen its bed. The channel on the north side of the island of Orleans, immediately below Quebec, which, according to the account of Charlevoix, was not sufficiently deep in the year 1720 to admit a shallop of a small size, except at the time of high tides, is at present found to be deep enough for the largest vessels, and is the channel most generally used.—Weld, p. 336.

"Upper Canada, down to the period when it was conquered by England, was in a very wild and unreclaimed condition. With the exception of the small location on the banks of the Detroit, it contained only detached posts at great distances, formed for military defense and the prosecution of the fur trade. The real settlement of Upper Canada took place in 1783, at the close of the first American war; at that time, not only a large body of troops were disbanded, but many inhabitants of the United States, who had adhered to Britain during this unfortunate contest, sought refuge within her colonies; and as these last were generally in a state of great destitution, the government felt disposed to treat them liberally, and afford the utmost possible compensation for their losses and sufferings. With this view, the whole land along the St. Lawrence above the French settlements, and also on Lake Ontario, to and around the Bay of Quiete, for the space of 150 miles, was formed into townships, originally entitled First, Second, Third, but to which regular names were afterward attached. These settlements were termed the United Empire Loyalists, and not only received an ample supply of land, but farming utensils, building materials, and subsistence for two years. A further engagement was made that every member of their families, on attaining the age of twenty-one, should have a fresh donation of 200 acres, which engagement has been strictly fulfilled. Military grants were at the same time bestowed at rates varying from 5000 for a field officer, to 200 for a private soldier.

"In 1791, Upper Canada had attained to such importance, that when Mr. Pitt determined to bestow a constitution on the colony, he formed this part into a separate government, giving to it the name of Upper, and to the early-settled districts that of Lower Canada. The former was not supposed, after all, to contain at that time above 10,000 inhabitants. General Simcoe, however, in 1794, founded the town of York,[222]which was fixed on as the seat of government, and made the most strenuous efforts to encourage colonists to settle in the neighborhood. They came in considerable numbers, though chiefly from the United States. It was not till 1803 that, through the exertions of Colonel Talbot, emigration from Britain was commenced on any large scale. The result of these measures was, that in 1811 the country was found to contain about 9623 persons paying taxes.

Lower Canada is comprised within the parallels of 45° and 52° north latitude, and the meridians of 59·50° to 80·6° west of Greenwich; the entire province, as far as its boundaries will admit of estimation, contains about a quarter of a million square miles, or 160,000,000 of acres. Upper Canada is comprised within the parallels of 41° to 49° north, and the meridians of 74° to 117° west of Greenwich, embracing an area of about 100,000 square miles, or 64,000,000 acres. The following are the words of the order in council by which Canada was in 1791 divided into two provinces. "To commence at a stone boundary on the north bank of the Lake St. Francis, at the cove west of Point au Baudet, in the limit between the township of Lancaster and the seigniory of New Longueuil, running along the said limit in the direction of N. 34 W. to the westernmost angle of the said seigniory of New Longueuil; then along the N.W. boundary of the seigniory of Vaudreuil, running N. 25 E. until it strikes the Ottawa River; to ascend the said river into the Lake Temiscaming, and from the head of the said lake by a line drawn due N. until it strikes the boundary of Hudson's Bay, including all the territory to the westward and southward of the said line to the utmost extent of the country commonly called or known by the name of Canada." The want of clearness in the above delineation, added to the imperfections of the map on which it was drawn, particularly as regarded the westwardly angle of the seigniory of New Longueuil, and the S.W. angle of Vaudreuil, which are represented as coincident, when, according to Colonel Bouchette, they are nine miles distant from each other, has naturally caused disputes as to the boundaries between Upper and Lower Canada.—Montgomery Martin'sHist. of Canada, p. 62; Murray'sBritish America, vol. i., p. 287.

"On the 5th of February, 1663, about half past five o'clock in the evening, a great rushing noise was heard throughout the whole extent of Canada. This noise caused the people to run out of their houses into the streets, as if their habitations had been on fire; but, instead of flames or smoke, they were surprised to see the walls reeling backward and forward, and the stones moving as if they were detached from each other. The bells sounded by the repeated shocks. The roofs of the buildings bent down, first on one side, and then on the other. The timbers, rafters, and planks cracked. The earth trembled violently, and caused the stakes of the palisades and palings to dance, in a manner that would have been incredible had we not actually seen it in many places. It was at this moment every one ran out of doors. Then were to be seen animals flying in every direction; children crying and screaming in the streets; men and women, seized with affright, stood horror-struck with the dreadful scene before them, unable to move, and ignorant where to fly for refuge from the tottering walls and trembling earth, which threatened every instant to crush them to death, or sink them into a profound and immeasurable abyss. Some threw themselves on their knees in the snow, crossing their breasts, and calling on their saints to relieve them from the dangers with which they were surrounded. Others passed the rest of this dreadful night in prayer; for the earthquake ceased not, but continued at short intervals with a certain undulating impulse, resembling the waves of the ocean; and the same qualmish sensations, or sickness at the stomach, was felt during the shocks as is experienced in a vessel at sea.

"The violence of the earthquake was greatest in the forest, where it appeared as if there was a battle raging between the trees; for not only their branches were destroyed, but even their trunks are said to have been detached from their places, and dashed against each other with inconceivable violence and confusion—so much so, that the Indians, in their figurative manner of speaking, declared that all the forests were drunk. The war also seemed to be carried on between the mountains, some of which were torn from their beds and thrown upon others, leaving immense chasms in the places from whence they had issued, and the very trees with which they were covered sunk down, leaving only their tops above the surface of the earth; others were completely overturned, their branches buried in the earth, and the roots only remained above ground. During this general wreck of nature, the ice, upward of six feet thick, was rent and thrown up in large pieces, and from the openings in many parts there issued thick clouds of smoke, or fountains of dirt and sand, which spouted up to a very considerable height. The springs were either choked up, or impregnated with sulphur; many rivers were totally lost; others were diverted from their course, and their waters entirely corrupted. Some of them became yellow, others red, and the great river of the St. Lawrence appeared entirely white, as far down as Tadoussac. This extraordinary phenomenon must astonish those who know the size of the river, and the immense body of waters in various parts, which must have required such an abundance of matter to whiten it. They write from Montreal that, during the earthquake, they plainly saw the stakes of the picketing or palisades jump up as if they had been dancing; and that of two doors in the same room, one opened and the other shut of their own accord; that the chimneys and tops of the houses bent like branches of the trees agitated with the wind; that when they went to walk they felt the earth following them, and rising at every step they took, something sticking against the soles of their feet, and other things in a very forcible and surprising manner.

"From Three Rivers they write that the first shock was the most violent, and commenced with a noise resembling thunder. The houses were agitated in the same manner as the tops of trees during a tempest, with a noise as if fire was crackling in the garrets. The shock lasted half an hour, or rather better, though its greatest force was properly not more than a quarter of an hour, and we believe there was not a single shock which did not cause the earth to open either more or less.

"As for the rest, we have remarked that, though this earthquake continued almost without intermission, yet it was not always of an equal violence. Sometimes it was like the pitching of a large vessel which dragged heavily at her anchors, and it was this motion which occasioned many to have a giddiness in their heads and a qualmishness in their stomachs. At other times the motion was hurried and irregular, creating sudden jerks, some of which were extremely violent; but the most common was a slight tremulous motion, which occurred frequently with little noise. Many of the French inhabitants and Indians, who were eye-witnesses to the scene, state that, a great way up the river of Trois Rivières, about eighteen miles below Quebec, the hills which bordered the river on either side, and which were of a prodigious height, were torn from their foundations, and plunged into the river, causing it to change its course, and spread itself over a large tract of land recently cleared; the broken earth mixed with the waters, and for several months changed the color of the great River St. Lawrence, into which that of Trois Rivières disembogues itself. In the course of this violent convulsion of nature, lakes appeared where none ever existed before; mountains were overthrown, swallowed up by the gaping, or precipitated into adjacent rivers, leaving in their places frightful chasms or level plains; falls and rapids were changed into gentle streams, and gentle streams into falls and rapids. Rivers in many parts of the country sought other beds, or totally disappeared. The earth and the mountains were entirely split and rent in innumerable places, creating chasms and precipices, whose depths have never yet been ascertained. Such devastation was also occasioned in the woods, that more than a thousand acres in our neighborhood were completely overturned; and where, but a short time before, nothing met the eye but one immense forest of trees, now were to be seen extensive cleared lands, apparently cut up by the plow.

"At Tadoussac (about 150 miles below Quebec, on the north side) the effect of the earthquake was not less violent than in other places; and such a heavy shower of volcanic ashes fell in that neighborhood, particularly in the River St. Lawrence, that the waters were as violently agitated as during a tempest. The Indians say that a vast volcano exists in Labrador. Near St. Paul's Bay (about fifty miles below Quebec, on the north side), a mountain, about a quarter of a league in circumference, situated on the shore of the St. Lawrence, was precipitated into the river, but, as if it had only made a plunge, it rose from the bottom, and became a small island, forming with the shore a convenient harbor, well sheltered from all winds. Lower down the river, toward Point Alouettes, an entire forest of considerable extent was loosened from the main bank, and slid into the River St. Lawrence, where the trees took fresh root. There are three circumstances, however, which have rendered this extraordinary earthquake particularly remarkable: the first is its duration, it having continued from February to August, that is to say, more than six months almost without intermission! It is true, the shocks were not always equally violent. In several places, as toward the mountains behind Quebec, the thundering noise and trembling motion continued successively for a considerable time. In others, as toward Tadoussac, the shock continued generally for two or three days at a time with much violence.

"The second circumstance relates to the extent of this earthquake, which, we believe, was universal throughout the whole of New France, for we learn that it was felt from L'Isle Percé and Gaspé, which are situated at the mouth of the St. Lawrence, to beyond Montreal; as also in New England, Acadia, and other places more remote. As far as it has come to our knowledge, this earthquake extended more than 600 miles in length, and about 300 in breadth. Hence 180,000 square miles of land were convulsed in the same day and at the same moment.

"The third circumstance, which appears the most remarkable of all, regards the extraordinary protection of Divine Providence, which has been extended to us and our habitations; for we have seen near us the large openings and chasms which the earthquake occasioned, and the prodigious extent of country which has been either totally lost or hideously convulsed, without our losing either man, woman, or child, or even having a hair of their head touched."—Jesuits' Journal, Quebec, 1663.

"The principle in both instances is alike: in the former, the caloric or vital heat of the body passes so rapidly from the hand into the cold iron as to destroy the continuous and organic structure of the part; in the latter, the caloric passes so rapidly from the hot iron into the hand as to produce the same effect: heat, in both cases, being the same; its passing into the body from the iron, or into the iron from the body, being equally injurious to vitality. From a similar cause, the incautious traveler in Canada is burned in the face by a very cold wind, with the same sensations as when he is exposed to the blast of an eastern sirocco. Milton thus alludes to the effects of cold in his description of the abode of Satan and his compeers. After adverting to Styx, he says,

'Beyond this flood, a frozen continentLies, dark and wild, beat with perpetual stormsOf whirlwind and dire hail, which on firm landThaws not, but gathers heap, and ruin seemsOf ancient pile; all else deep snow and ice;A gulf profound as that Serbonian bogBetwixt Damiata and Mount Casius old,Where armies whole have sunk: the parching airBurns frore (frozen), and cold performs the effect of fire.'

"This meteor is strongest and most frequent about the arctic circle, or between that and the parallel of 64°. It is now ascertained, we think, beyond all doubt, that the height of the Aurora, instead of being, as supposed by Mr. Dalton and others, above the region of the atmosphere, is, in fact, rarely above six or seven miles. This was satisfactorily proved by angles taken in the same moment at two distant places, always exceedingly small at one or both stations; by the extreme rapidity with which a beam darts from one side of the horizon to the opposite side, which could not happen if 100 miles high or upward; by its frequently darting its beamsbeneaththe clouds, and at very short distances from the earth's surface, and by its being acted upon by the wind. Mr. Hood was told by one of the partners of the Northwest Company that he once saw the coruscations of the Aurora Borealis so vivid and low that the Canadians fell on their faces, and began crying and praying, fearing lest they should be killed; that he threw away his gun and knife, that they might not attract the flashes, for they were within two feet from the earth, flitting along with incredible swiftness, and moving parallel to the surface; he added that they made a loud rustling noise, like the waving of a flag in a strong breeze. This rustling noise, which is universally asserted by the servants of the Northwest Company, was not heard by any of the officers of Captain Franklin's expedition, but he says that it would be an absurd degree of skepticism to doubt the fact any longer, for their observations had rather increased than diminished the probability of it. It has hitherto been supposed that the magnetic needle was not affected by the Aurora; but a vast number of experiments given in the tables prove that, in certain positions of the beams and arches, the needle was considerably drawn aside, and mostly so when the flashes were between the clouds and the earth, or when their actions were quick, their light vivid, and the atmosphere hazy."—Franklin'sJourney to the Polar Sea, Nos. II. and III. of the Appendix.

The following is Charlevoix's description of the Aurora Borealis, never before witnessed by the French colonists:

"Un autre phénomène, qui parôit dans l'air, mériteroit bien qu'on s'étudiât à en découvrir la cause. Dans le tems le plus serein, on apperçoit tout à coup au milieu de la nuit de nuages d'une blancheur extraordinaire, et au travers de ces nuages une lumière très-éclatante. Lors même qu'on ne sent pas un souffle de vent, ces nuages sont chassés avec une très-grande vitesse, et prennent toutes sortes de figures. Plus la nuit est obscure, plus la lumière est vive: elle l'est même quelquefois à un point, qu'on peut lire à sa lueur beaucoup plus aisément, qu'à celle de la lune dans son plein.

"On dira peut-être que ce n'est qu'une réfraction des raïons du soleil, qui par cette hauteur ne s'éloigne pas beaucoup de l'horison pendant les nuits de l'été, et qu'encore qu'il n'y ait point de vent dans la basse région de l'air, il peut y en avoir dans la supérieure, ce qui est vrai; mais ce qui me fait juger qu'il y a encore une autre de ce météore, c'est que pendant l'hyver même, la lune paroît souvent environnée d'arc-en-ciel de couleurs différentes, et toutes très-vives. Pour moi je suis persuadé que ces effets doivent être attribués en partie à des exhalaisons nitreuses, qui pendant le jour ont été attirées et enfluencées par le soleil."

"Very distant posterity will one day decide whether, as Mr. Leslie has endeavored to prove by ingenious hypothesis (An Experimental Inquiry into the Nature and Propagation of Heat, 1804), 2400 years are sufficient to augment the mean temperature of the atmosphere a single degree. However slow this increment may be, we must admit that an hypothesis, according to which organic life seems gradually to augment on the globe, occupies more agreeably our imagination than the old system of the cooling of our planet and the accumulation of the polar ice."—Humboldt'sPersonal Narrative, vol. ii., p. 83.

"A point of much interest is the comparison of the actual temperature of the globe with that of the same regions in former ages. The evidence which justifies the conclusion that no change has occurred but from local or superficial causes, is worth studying, were it only for its variety and singularity. We might begin with Laplace's conclusion, that the mean heat can not be altered by 1° of Réaumur since the time of Hipparchus, inasmuch as the dimensions of the globe would be thereby changed in a small amount, its angular velocity be increased or diminished, and a sensible difference be made in the length of the day, which difference does not exist. We might then proceed to the argument urged by Biot and Champollion, from the identity of the time of inundation in the Nile, 5000 years ago, the periodical rains producing which depend upon and indicate the degree and distribution of heat over a vast equatorial region. Next we might turn to the method of Professor Schaw, in his work on the comparative temperature of ancient and modern times, founded on the northern and southern limits of production of different animals and plants in any given country, as they come recorded to us by ancient writers, compared with the observations of our own day. The result of general identity is obtained by this method also; and the same remark may be extended to the miscellaneous proofs derived from other passages in ancient writers, numerously collated, respecting the climate of particular regions and localities. There is no amount of diversity shown by this evidence which does not admit of explanation from local and accidental causes, many of them belonging to the agency of man himself, on the surface of the earth."—Quarterly Review, September, 1848.

"Several planters attribute the failure of the cotton crop this year (1842) to the unusual size and number of the icebergs, which floated southward last spring from Hudson's and Baffin's Bays, and may have cooled the sea and checked the early growth of the cotton plant, so numerous and remote are the disturbing causes of meteorology! Forty degrees of latitude intervene between the region where the ice-floes are generated and that where the crops are raised, whose death-warrant they are supposed to have carried with them."—Lyell'sAmerica, vol. i., p. 174.

No. XXV.

The theory by which Dr. Brewster seeks to account for the peculiarities of the American climate is the following: "He supposes that the poles of the globe and the isothermal poles are by no means coincident, and that, on the contrary, there exist two different points, within a few degrees of the poles, where the cold is greatest in both hemispheres. These points are believed by Dr. Brewster to be situated about the eightieth parallel of latitude, and in the meridians of 95° east and 100° west longitude. The meridians of these isothermal poles[223]he considers as lying nearly at right angles to the parallels of what might be called the meteorological latitudes, which, according to his theory, appear to have an obliquity of direction as regards the equator something like the zodiac. Thus the cold circle of latitude that passes through Siberia would be the same that traverses the frigid atmosphere of Canada. This theory would go some length toward explaining the causes of the gradual decrease of the severity of cold in the south of Europe, and lead us to the conclusion that eventually the cold meridian of Canada may work its way westward, and leave that part of America to an enjoyment of the same temperature as those European countries situated in corresponding latitudes. That the temperature of the air has been modified by agricultural operations can not be denied, but that these operations should of themselves be capable of producing the changes known to have taken place in the course of ages in Europe, where formerly the Tiber used to be often frozen, and snow was by no means uncommon at Rome;[224]when the Euxine Sea, the Rhone, and the Rhine, were almost every year covered with ice, of sufficient thickness to bear considerable burdens, it is scarcely possible rationally to admit; and, indeed, the meteorological observations, as far as they go in Canada, serve rather to disprove than to establish the fact."—Bouchette, vol. i., p. 335.

"The earliest record of the climate of Canada is that contained in the 'Fastes Chronologiques,' and refers to the period of Cartier's second voyage. On the 15th of November, 1535, Old Style, the vessels in the River St. Charles were surrounded by ice, and the Indians informed Cartier that the whole river was frozen over as far as Montreal. On the 22d of February, 1536, the River St. Lawrence became navigable for canoes opposite to Quebec, but the ice remained firm in the St. Croix harbor. On the 5th of April his vessels were disengaged from the ice. To obtain the modern dates, it will be necessary to add eleven days to each period.

"The later meteorological statistics do not prove that the progressive opening of the country has had so powerful an influence upon the temperature of the atmosphere as is generally supposed. Its chief tendency seems to be to lengthen the summer, and thus abridge the duration of winter. That the gradual removal of the forests to make room for open fields contributes to augment the summer temperature, is undoubtedly true, since it is well known that the atmosphere itself is not heated by the direct rays of the sun, but that its warmth springs from the earth, and that the degree of this warmth is entirely governed by the quantum of heat absorbed through the earth's surface. The progressive settlement of the country may then be expected to benefit the climate, by its throwing open to the direct action of the sun a more extended surface of territory; and this benefit will be more sensibly felt at night, from the earth's having imbibed a sufficient quantity of caloric to temper the coolness of the air between the setting and rising of the sun. In an agricultural point of view, such an improvement in the climate of Canada will be of great moment, as the coldness of the nights is generally the cause of blight in tender fruits and plants; and from its equalizing the temperature, probably render the climate capable of maturing fruits that are indigenous to warm countries.

"Notwithstanding the opposing testimony of meteorological data, we have the assertion of some of the oldest inhabitants of the country that the climate of Canada has become perceptibly milder within their recollection, and are thus left to conciliate this traditional record with contradictory facts, and the only mode of doing so appears to be the application of their remarks, more to the duration of the mild season than the degrees of cold that were indicated by the thermometer in the course of the year."—Bouchette, vol. i., p. 334, 340, 1831; Lambert'sTravels through Canadain 1808, vol. i., p. 119.

Kalm says in 1748, September 12th, "The weather about this time was like the beginning of our August, Old Style. Therefore it seems that autumn commences a whole month later in Canada than in the midst of Sweden."—P. 682.

The Vitis vinifera is found in America in its wild state; in James's "Expedition to the Rocky Mountains" it is thus described: "The small elms along this valley were bending under the weight of innumerable grape vines, now loaded with ripe fruit, the purple clusters crowded in such profusion as almost to give a coloring to the landscape. On the opposite side of the river was a range of low sand-hills, fringed with vines, rising not more than a foot or eighteen inches from the surface. On examination, we found these hillocks had been produced exclusively by the agency of the grape vines, arresting the sand as it was borne along by the wind until such quantities had been accumulated as to bury every part of the plant except the end of the branches. Many of these were so loaded with fruit as to present nothing to the eye but a series of clusters, so closely arranged as to conceal every part of the stem. The fruit of these vines is incomparably finer than that of any other native or exotic which we have met with in the United States. The burying of the greater part of the trunk with its larger branches produces the effect of pruning, inasmuch as it prevents the unfolding of leaves and flowers on the parts below the surface, while the protruded ends of the branches enjoy an increased degree of light and heat from the reflection of the sand. It is owing, undoubtedly, to these causes that the grapes in question are far superior to the fruit of the same vine under ordinary circumstances. The treatment here employed by nature to bring to perfection the fruit of the vine may be imitated, but, without the peculiarities of soil and exposure, can with difficulty be carried to the same magnificent extent. Here are hundreds of acres, covered with a movable surface of sand, and abounding in vines, which, left to the agency of the sun and of the winds, are, by their operation, placed in more favorable circumstances than it is in the power of man to so great an extent to afford."—Vol. ii., p. 315, 316.

"Fir-trees, Thuja, and Cypress-trees are a northern type, which is very rare in the tropical regions. The freshness of their evergreen leaves cheers the desert winter landscape; it proclaims to the inhabitants of these regions that although snow and ice cover the earth, the internal life of the plants, like the fire of Prometheus, is never extinguished."—Cosmos, vol. ii., p. 90.

"There are upward of twenty species of Pinus, of which one half are natives of Canada, Nova Scotia, or Newfoundland.

"Pinus Balsamea(Balm of Gilead Fir, or American Silver Fir) grows to the height of fifty feet, and is an elegant tree, resembling the silver fir of Europe. The resin of this species is the common Canada Balsam, which is often substituted for the Balm of Gilead. It is found in small blisters on the bark, extracted by incision, and received in a limpid state into a shell or cup. This tree has long been cultivated for curiosity in England, but in general, though it grows to a considerable size and height, scarcely survives above twenty years, which seems to be the natural period of its existence. Mr. Lambert mentions some older trees of this species at Woburn and Warwick Castle.

"Pinus Canadensis(Hemlock Spruce) is a beautiful and very large tree, bearing some resemblance in its foliage to the common yew. Peter Collinson records his having introduced this tree to the English collections in 1736, and a fine specimen of it is, or was, in his garden at Mill Hill.

"Pinus Nigra(Black or Double Spruce) is found from Canada to Nova Scotia, and terminates in latitude 65°. It was introduced into England about the year 1700, but not much cultivated there.

"Pinus Alba(White Spruce) flourishes from latitude 43° northward. Its growth is nearly equal to that of the European silver fir, 140 feet in height. It is one of the most ornamental of theAbiestribe (those having single, not fasciculated leaves); the branches feather down to the ground, and the leaves have a beautiful and peculiar glaucous hue. From the young shoots of this tree (also from Pinus Nigra) is obtained the resinous extract from which spruce beer is made: good turpentine is obtained from the bark. This tree was cultivated in England by Bishop Compton before 1700.

"Pinus Resinosa(Pitch Pine) grows in Canada in close forests, and is distinguished for its great height and smooth red bark, whence it is often called Red Pine by the French population. This tree is the glory of Canada. Its timber, in color, quality, and durability, appears to be in every respect equal to the best Riga, and in one particular superior, that of being quite free from knots. It was first raised in England by the Duke of Northumberland at Zion House, where many of this species are still to be seen flowering in May.

"Pinus Banksiana(Labrador Scrub, or Gray Pine) inhabits cold, barren, and rocky situations. The finest trees of this species in England are at Pain's Hill and Kew.

"Pinus Strobus(White, or Weymouth Pine) is the largest species on the eastern side of the Rocky Mountains, being sometimes 200 feet high, and the trunk five feet in diameter. The attention which Lord Weymouth, afterward Marquis of Bath, gave to the cultivation of this valuable tree has justly stamped it with his name. It is now generally diffused through every considerable plantation in England. When growing in open situations, it is feathered to the ground; but, as generally found in the Canadian forests, it is little more than an immense stick with a quantity of brush at its head, in about the same proportion as the hair on the tail of an elephant. It is of this tree that in general the forests of all British America are composed, and it is, in fact, peculiar to America. It is called in commerce White Pine, Yellow Pine, or American Pine. The timber is very valuable for masts. The age to which this tree arrives is not known: 1500 annular divisions have been counted.

"Pinus Pendula(Black Larch, or Hackmatack) is a beautiful and large tree, generally resembling the larch of Europe. The buds are black, and yield a fine turpentine. This tree was first raised in England by the celebrated Peter Collinson, whose original tree, one of the treasures of the Mill Hill garden, was cut down about the year 1800 to make a rail! Few exotics are more worthy of general cultivation. The wood is at least equal to the European larch.

"Pinus Microcarpa(Red Larch) resembles the preceding so much, that Michaux and Wildman confounded the two species together. The red larch, however, is now clearly distinguished as a distinct kind. It is named by the voyageurs L'Epinette Rouge, and by the Hudson's Bay men Juniper."—H. Murray'sBritish America, vol. iii., p. 328; R. M. Martin, p. 254; Rees'sCyclopædia, art. Pinus.

"The canoes that navigate the Canadian lakes are among the most ingenious and useful of the Indian manufactures, and nothing that European ingenuity has devised is so well adapted to the habits and necessities of their mode of life. They are made of the bark of the birch-tree; and of all the various contrivances for transporting burdens by water, these vessels are the most extraordinary. From the slightness of their construction, they would appear to be totally inadequate to contend against the rapids they are continually exposed to. They are of various lengths, from twelve to thirty feet (the latter used only by the Hudson's Bay Company); their breadth from four to six feet, diminishing to a point at each end without distinction. The exterior is the bark of the birch-tree, scarcely the eighth part of an inch in thickness: it is kept distended by thin hoops and the bark; the gunwale is a narrow lath, to which the hoop and the bark are sewed with narrow strips of the roots of the white cedar-tree; and the joinings in the bark are rendered water-proof by a species of gum, said to be collected from the wild cherry-tree, which soon becomes perfectly hard. No iron work or nails are employed in their construction; and they are so light, that the common-sized ones are easily carried for several miles by a man of moderate strength. They are worked by paddles over the sides, and the dexterity of the Indians in working them is surprising. They, of course, push them forward, and not backward, as in the operation of rowing. The largest description will carry about five tons of merchandise, besides eight or ten men. The great objection that attends the use of bark canoes is the difficulty of keeping them water-tight. It requires the greatest attention to prevent them from touching a rock, or even the shore, as they would otherwise break; hence they are never brought near to the bank. Two men keep the canoe afloat at a distance, while the rest of the crew load or unload her. The canoe is unloaded every night, raised out of the water, and left on the beach bottom upward. This is also occasionally done when they stop during the day: it affords an opportunity of allowing the canoe to dry, otherwise the bark absorbs much water, and becomes very heavy. All motion on the part of those on board is to be avoided, as it causes the pitch to crack, and renders the canoe leaky."—Keating'sNarrative of an Expedition to the Source of St. Peter's River, vol. ii., p. 72, quoted in Sir George Simpson'sOverland Journey Round the World, vol. i., p. 14.

La Hontan, in 1684, gives the same description of the bark canoes, and complains of "the inconvenience of their brittle and tender fabric. If they do but touch or grate upon stone or sand, the cracks of the bark fly open, upon which the water gets in, and spoils the provisions and merchandise. Every day there is some new chink or seam to be gummed over. At night they are always unloaded and carried on shore, where they are made fast with pegs, lest the wind should blow them away."

Charlevoix gives a nearly similar account in 1720, vol. v., p. 285. He adds: "Tous ces canots, jusqu'au plus petits, portent la voile et avec un bon vent peuvent faire vingt lieues par jour. Sans voiles il faut avoir de bons canoteurs pour en faire douze dans une eau morte."

"Many of the species ofAcerform large, ornamental, and valuable trees. The kinds in most esteem for making sugar areAcer dasycarpum(white, or soft maple),Acer nigrum(black sugar maple), andAcer saccharinum(the sugar maple), the last two yielding the greatest quantity of sugar. The process by which the sap is obtained is extremely simple, nothing more being necessary than to bore a hole in the tree, and conduct the flowing liquid, by means of a hollowed piece of wood, into a vessel beneath. Whatever quantity of sap is collected, it must be boiled down the same evening, as it is liable to be spoiled by fermentation in the course of a few hours. The operation of boiling is generally performed in a very primitive way: it is thus described by the intelligent authoress ofBackwoods of Canada: 'A pole was fixed across two forked stakes strong enough to bear the weight of the big kettle. The employment during the day was emptying the troughs and chopping wood to supply the fires. In the evening they lit the fires and began boiling down the sap. It was a pretty and picturesque sight to see the sugar boilers, with their bright log-fire among the trees, now stirring up the blazing pile, now throwing in the liquid, and stirring it down with a big ladle. When the fire grew fierce it boiled and foamed up in the kettle, and they had to throw in fresh sap to keep it from running over. When the sap begins to thicken into molasses, it is then brought to the sugar boiler to be finished. The process is simple: it only requires attention in skimming, and keeping the mass from boiling over, till it has arrived at the sugaring point, which is ascertained by dropping a little into cold water. When it is near the proper consistency, the kettle or pot becomes full of yellow froth, that dimples and rises in large bubbles from beneath. These throw out puffs of steam, and when the molasses is in this stage it is nearly converted into sugar. Those who pay great attention to keeping the liquid free from scum, and understand the precise sugaring point, will produce an article little, if at all, inferior to Muscovado.' It is, however, often adulterated with flour, which thickens and renders it heavy. It is very hard, and requires to be scraped with a knife when used for tea, otherwise the lumps would be a considerable time in dissolving. The Canadians say that it possesses medicinal qualities, for which they eat it in large lumps. It very possibly acts as a corrective to the vast quantity of fat pork which they consume, as it possesses a greater degree of acidity than the West India sugar. Before salt was in use, sugar was eaten with meat, as a corrective; hence, probably, the custom of eating sweet apple-sauce with pork and goose, and currant-jelly with hare and venison."—Lambert, vol. i., p. 84.

"The production of maple sugar amounted (in 1836) to about 25,000 cwt. annually. A plantation of maple is termed 'suegari,' and is considered very valuable: the sugar sells from 3d.to 6d.per pound. A moderate tree is said to yield from twenty to thirty gallons of the sap, from which may be extracted five or six pounds of sugar. Nor is sugar the only product to be obtained from this valuable tree: strong and excellent vinegar is made from it, as well as good wine; and, with the addition of hops, sound and pleasant beer may be had at a very trifling expense."—H. Murray'sCanada, vol. iii., p. 315; Gray'sCanada, p. 224.

"It is a very remarkable fact that these trees, after having been tapped for six or seven successive years, always yield more sap than they do on being first wounded. This sap, however, is not so rich as that which the trees distill for the first time; but, from its coming in an increased portion, as much sugar is generally produced from a single tree on the fifth or sixth year of its being tapped as on the first.

"The ingenious Mr. Nooth, of Quebec, who is at the head of the general hospital in Canada, has made a variety of experiments upon the manufacture of maple sugar. He has granulated, and also refined it, so as to render it equal to the best lump sugar that is made in England. To convince the Canadians also, who are as incredulous on some points as they are credulous on others, that it was really maple sugar that they saw thus refined, he has contrived to have large lumps, exhibiting the sugar in its different stages toward refinement, the lower part of the lumps being left hard, similar to the common cakes, the middle part granulated, and the upper part refined. Dr. Nooth has calculated that the sale of the molasses alone would be fully adequate to the expense of refining the maple sugar, if a manufactory for that purpose were established. Some attempts have been made to establish one of the kind at Quebec, but they have never succeeded, as the persons by whom they were made were adventurers that had not sufficient capital for such an undertaking."—Weld, 1800, p. 271.

Charlevoix says in hisJournal, "On me régale ici d'eau d'erable—elle est délicieuse, d'un fraícheur admirable et fort saine. Pour qu'elle coule avec abondance, il faut qu'il y ait beaucoup de neiges sur la terre, qu'il ait gelé pendant la nuit, que le ciel soit serein, et que le vent ne soit pas trop froid. Nos érables auroient peut-être la même vertu, si nous avions en France autant de neiges qu'en Canada, et si elles y duroient aussi lontems. J'en ai donné à foudre à un refineur d'Orleans qui n'y a trouvé d'autre défaut que ce qu'il n'avoit pas été suffisamment égouté. Il le croyoit même de meilleure qualité de l'autre."—Vol. v., p. 181.

"Quelques nations tirent leur subsistance, d'une sorte de grain que la Nature produit d'elle-même; on le nomme le folle-avoine, dont les Français ont transporté le nom à quelques-unes de ces nations. C'est une plante marécageuse qui approche assez de l'avoine, mais qui est mieux nourrie. Les sauvages vont la chercher dans leurs canots, au tems de sa maturité. Ils ne font que sécouer les épis, les quels s'égraissent facilement, de sorte que leurs canots sont bientôt remplis, et leurs provisions bientôt faìtes, sans qu'ils soient obligés de labourer ni de semer."—Lafitau, tom. ii., 96.

This grain is theZizania aquaticaof Linnæus. Kalm calls it the water tare-grass, and says that "the Indians reckon it among their dainty dishes. It grows in plenty in their lakes, in stagnant waters, and sometimes in rivers which flow slowly. They gather its seeds in October, and prepare them in different ways, and chiefly as groats, which take almost as well as rice."—Kalm, in Pinkerton, vol. xiii., p. 696.

"Common in all the waters from Canada to Florida, and known by the name of Tuscarora,[225]or wild rice."—Pursh. Sir Joseph Banks introduced it into this country in 1790, and cultivated it abundantly in the ponds of his villa of Spring Grove. The seeds were obtained from Canada in jars of water. Mr. Lambert is of opinion that this grain might be cultivated in many shallow lakes of Ireland, and turned to considerable advantage.
