"_Pinus Strobus_ (White, or Weymouth Pine) is the largest species on the eastern side of the Rocky Mountains, being sometimes 200 feet high, and the trunk five feet in diameter. The attention which Lord Weymouth, afterward Marquis of Bath, gave to the cultivation of this valuable tree has justly stamped it with his name. It is now generally diffused through every considerable plantation in England. When growing in open situations, it is feathered to the ground; but, as generally found in the Canadian forests, it is little more than an immense stick with a quantity of brush at its head, in about the same proportion as the hair on the tail of an elephant. It is of this tree that in general the forests of all British America are composed, and it is, in fact, peculiar to America. It is called in commerce White Pine, Yellow Pine, or American Pine. The timber is very valuable for masts. The age to which this tree arrives is not known: 1500 annular divisions have been counted. "_Pinus Pendula_ (Black Larch, or Hackmatack) is a beautiful and large tree, generally resembling the larch of Europe. The buds are black, and yield a fine turpentine. This tree was first raised in England by the celebrated Peter Collinson, whose original tree, one of the treasures of the Mill Hill garden, was cut down about the year 1800 to make a rail! Few exotics are more worthy of general cultivation. The wood is at least equal to the European larch. "_Pinus Microcarpa_ (Red Larch) resembles the preceding so much, that Michaux and Wildman confounded the two species together. The red larch, however, is now clearly distinguished as a distinct kind. It is named by the voyageurs L'Epinette Rouge, and by the Hudson's Bay men Juniper."--H. Murray's _British America_, vol. iii., p. 328; R. M. Martin, p. 254; Rees's _Cyclopædia_, art. Pinus.
