Goppert, and Endlicher have already discovered five species of Araucarias belonging to the Ancient World in the lias, in chalk, and in beds of lignite (Englicher, Coniferre fossiles, p. 301). Pinus Douglasii (Sabine), in the valleys of the Rocky Mountains and on the banks of the Columbia River (north lat. 43°-52°). The meritorious Scotch botanist from whom this tree is named perished in 1833 by a dreadful death in collecting plants in the Sandwich Islands, where he had arrived from New California. He fell inadvertently into a pit in which a fierce bull belonging to the cattle which have become wild, had previously fallen, and was gored and trampled to death. By exact measurement a stem of Pinus Douglasii was 5H English feet in girth at 3 feet above the ground, and its height was 245 English feet. (See Journal of the Royal Institution, 1826, p. 325.) Pinus trigona (Rafinesque ), on the western declivity of the Rocky Mountains, described in Lewis and Clarke's Travels to the Source of the Missouri River and across the American Continent to the Pacific Ocean (1804-1806), 1814, p. 456. This gigantic Fir was measured with great care ; the trunks were often 38 to 45 English feet in girth, 6 feet above the ground : one tree was 300 English feet high, and the first 192 feet were without any divison into branches. Pinus Strobus grows in the eastern parts of the United States of North America, especially on the east of the Mississippi; but it is found again in the Rocky Mountains from the sources of the Columbia to Mount Hood, or from 43° to 54° N. lat. It is called in Europe the Weymouth Pine, and in North America the White Pine; its ordinary height does not exceed 160 to 192 Eng. feet, but several trees of 250 to 266 Eng. feet have been seen in New Hampshire. (Dwight, Travels, vol. i. p. 36; and Emerson's Report on the Trees and Shrubs growing naturally in the Forests of Massachusetts, 1846, pp. 60-66.) Sequoia gigantea (Endl.), Condylocarpus (Sal.) from New California; like Pinus trigona, about 300 English feet high. The nature of the soil, and the circumstances of heat and moisture on which the nourishment of plants depends, no doubt influence the |
