[156] Acosta is the first philosopher who endeavored to account for the different degrees of heat in the Old and New Continents by the agency of the winds which blow in each, (Hist. Moral., lib. ii. and iii.) M. de Buffon adopted the same theory, and illustrated it with many new observations. "The prevailing winds, both in Upper and Lower Canada, are the northeast, northwest, and southwest, which all have a considerable influence on the temperature of the atmosphere and the state of the weather. The southwest wind is the most prevalent, but it is generally moderate, and accompanied by clear skies; and the northeast and easterly winds usually bring with them continued rain in summer, and snow in winter; the northwest is remarkable for its dryness and elasticity, and, from its gathering an intense degree of frigor as it sweeps over the frozen plains and ice-bound hills in that quarter of the continent, invariably brings with it a perceptible degree of cold. Winds from due north, south, or west are not frequent. At Quebec, the direction of the wind often changes with the tide, which is felt for nearly sixty miles higher up the stream of the St. Lawrence."—Bonchette, vol. i., p. 343.
"The northwest wind is uncommonly dry, and brings with it fresh animation and vigor to every living thing. Although this wind is so very piercing in winter, yet the people never complain so much of cold as when the northeast wind blows. The northeast wind is also cold, but it renders the air raw and damp. That from the southeast is damp, but warm. Rain or snow usually falls when the wind comes from any point toward the east. The northwest wind, from coming over such an immense tract of land, must necessarily be dry; and, coming from regions eternally covered with mounds of snow and ice, it must also be cold. The northeast wind, from traversing the frozen seas, must be cold likewise; but, from passing over such a large portion of the watery main afterward, it brings damp and moisture with it. All those from the northeast are damp, and loaded with vapors from the same cause. Southerly winds, from crossing the warm regions between the tropics, are attended with heats; and the southwest wind, from passing, like the northwest, over a great extent of land, is dry at the same time."—Weld's Travels in America, 4th ed., p. 184.
Kalm says, p. 748, that he was assured that "the northeast wind, when it is very violent in winter, pierces through walls of a moderate thickness, so that the whole wall on the inside of the house is covered with snow, or a thick hoar frost. The wind damages severely the houses that are built of stone, so that the owners are frequently obliged to repair them on the northeast side. In summer the north wind is generally attended with rain."—Kalm in Pinkerton, vol. xiii., p. 651.
[157] "Many of these mountains are very high. During my stay in Canada, I asked many people who have traveled much in North America whether they ever met with mountains so high that the snow never melts on them in summer, to which they always answered in the negative. They say that the snow sometimes stays on the highest, viz., on some of those between Canada and the English colonies during a part of the summer, but that it melts as soon as the great heat begins."—Kalm, p. 671.
[158] "It is worthy of remark, and not a little surprising, that so large a river as the St. Lawrence, in latitude 47°, should be shut up with ice as soon, and continue as long shut up, as the comparatively small river, the Neva, in latitude 60°."—Gray's Canada, p. 320.
[159] "The following curious experiments were made some years ago at Quebec, by Major Williams, of the Artillery. Iron shells of different sizes, from the thirteen-inch shell to the cohorn of four inches diameter, were nearly filled with water, and an iron plug was driven in at the fuse-hole by a sledge-hammer. It was found, however, that the plug could never be driven so firmly into the fuse-hole as to resist the expanding ice, which pushed it out with great force and velocity, and a bolt or cylinder of ice immediately shot up from the hole; but when a plug was used that had springs which would expand and lay hold of the inside of the cavity, so that it could not possibly be pushed out, the force of expansion split the shell. The amazing force of expansion is also shown from the distance to which these iron plugs are thrown out of the fuse-hole. A plug of two pounds and a half weight was thrown no less than 415 feet from the shell; the fuse axis was at an angle of 45°; the thermometer showed 51° below the freezing point. Here you see ice and gunpowder performing the same operations. That similar effects should proceed from such dissimilar causes is very extraordinary."—Gray's Canada, p. 309.

[165] "In Europe, in Asia, in Africa, and even in South America, the primeval trees, however much their magnitude may arrest admiration, do not grow in the promiscuous style that prevails in the general character of the North American woods. Many varieties of the pine, intermingled with birch, maple, beech, oak, and numerous other tribes, branch luxuriantly over the banks of lakes and rivers, extend in stately grandeur along the plains, and stretch proudly up to the very summits of the mountains. It is impossible to exaggerate the autumnal beauty of these forests; nothing under heaven can be compared to its effulgent grandeur. Two or three frosty nights in the decline of autumn transform the boundless verdure of a whole empire into every possible tint of brilliant scarlet, rich violet, every shade of blue and brown, vivid crimson, and glittering yellow. The stern, inexorable fir tribes alone maintain their eternal somber green. All others, in mountains or in villages, burst into the most glorious vegetable beauty, and exhibit the most splendid and most enchanting panorama on earth."—M'Gregor, p. 79, 80.
Mr. Weld says, "The varied hues of the trees at this season of the year (autumn) can hardly be imagined by those who never have had an opportunity of observing them; and, indeed, as others have often remarked before, were a painter to attempt to color a picture from them, it would be condemned in Europe as totally different from any thing that ever existed in nature."—Weld, p. 510.
"I can only compare the brightness of the faded leaves, scarlet, purple, and yellow, to that of tulips."—Lyell's America, vol. i., p. 107.

[167] "One of the most striking features in the vegetation of Canada is the number of species belonging to the genera Solidago, Aster, Quercus, and Pinus. It is also distinguished for the many plants contained in the Orders, or natural families—Grossulaceæ, Onograceæ, Hypericaceæ, Aceraceæ, Betulaceæ, Juglandaceæ, and Vacciniaceæ; and for the presence of the peculiar families—Podophyllæ, Sarraceniaceæ, and Hydrophyllaceæ. There is, on the contrary, the climate being considered, a remarkable paucity of Cruciferæ and Umbelliferæ, and, what is most extraordinary, a total absence of the genus Erica (heath),[168] which covers so many thousands of acres in corresponding latitudes in Europe.
