340 PHYSIOGNOMY OF .PLANTS. 



G-oppert, and Endlicher have already discovered five species of 

 Araucarias belonging to the Ancient World in the lias, in chalk, and 

 in beds of lignite (Endlicher, Coniferse 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 57 J 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 Eir 

 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 division 

 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 Cali- 

 fornia ; 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
