Pines which clothe the face of North-west America, but like 
Pinus resinosa, which grows among them, they are scattered 
singly over the plains, and may be considered to form a sort of 
connecting link between the gloomy forests of the north and 
the more tropical-like verdure of California. 
The trunk grows from 150 to above 200 feet in height, vary- 
ing from 20 to near 60 feet in circumference. One specimen, 
which had been blown down by the wind,—and this was certainly 
not the largest which I saw,—was of the following dimensions. 
—lts entire length was 215 feet; its circumference three feet 
from the ground was 57 feet 9 inches; and at 134 feet from the 
ground, 17 feet 5 inches. The trunk is unusually straight, and 
destitute of branches about two-thirds of the height; the bark is 
uncommonly smooth for such large timber, of a light-brown 
colour on the south, and bleached on the north side. The 
branches are rather pendulous, and form an open pyramidal 
head, with that appearance which is peculiar to the Abies tribe. 
The leaves are between 4 and 5 inches long, and grow in fives, 
with a short sheath like those of Pinus Strobus ; they are rigid, 
of a bright-green colour, but not glossy, and from minute den- 
ticulations of the margin are scabrous to the touch. The cones 
are pendulous from the extremities of the branches; they are 
two years in acquiring their full growth, are at first upright, and 
do not begin to droop I believe till the second year: when 
young they have a very taper figure; when ripe they are about 
11 inches in circumference at the thickest part, and vary from 
12 to 16 inches in length. The scales are lax, rounded at the 
apex, and perfectly destitute of spines. "The seeds are large, 
8 lines long and 4 broad, oval; and, like that of Pinus Pinea, 
their kernel is sweet and very pleasant to the taste. The wing 
is membranous, of a dolabriform figure and fuliginous colour,
