"We missed, also, the small 'crimson-tipped daisy' on the green lawns, and were told that they have been often cultivated with care, but are found to wither when exposed to the dry air and bright sun of this climate. When weeds so common with us can not be reared here, we cease to wonder at the dissimilarity of the native Flora of the New World. Yet, wherever the aboriginal forests are cleared, we see orchards, gardens, and arable lands filled with the same fruit-trees, the same grain and vegetables, as in Europe, so bountifully has Nature provided that the plants most useful to man should be capable, like himself, of becoming cosmopolites."--Lyell's _Travels in North America_, vol. i., p. 5.] [Footnote 169: The Kalmias were so named by Linnaeus in honor of Professor Kalm, a favorite pupil of the great botanist.] [Footnote 170: See Appendix, No. XXVII. (see Vol II)] [Footnote 171: The oak from the dense forests of Canada, into which the sun's rays never penetrate, is more porous, more abundant in sap, and more prone to the dry rot than the oak grown in any other country. Canadian timber has increased in value since the causes of its former rapid decay have been more fully understood. Mr. Nathaniel Gould asserts that the wane of the moon is now universally considered the best season for felling timber, both in the United States and in Canada. The Americans contract for their ship timber to be felled or girdled between the 20th of October and the 12th of February. Dry rot being probably caused by the natural moisture or sap being left in the wood, the less there is in the tree when cut, the longer it will keep sound. As regards the Canadian oak, it is stated by Mr. M'Taggart (the engineer, who so ably distinguished himself while in the colony), that it is not so durable as that of the British, the fiber not being so compact and strong; it grows in extensive groves near the banks of large lakes and rivers, sometimes found growing to 50 feet in length by 2 feet 6 inches; its specific gravity is greater than water, and therefore, when floated down in rafts, it is rendered buoyant with cross bars of pine. It is easily squared with the hatchet, and answers well for ship-building and heavy work; will endure the seasons for about fifteen years,[172] and does not decay in England so soon as in Canada.--Montgomery Martin's _Canada_, p. 257; Gray's _Canada_, p. 207.]
