LARCH. 
Two species of larch are cut into lumber, but the eastern species is 
generally called tamarack (Lariz laricina). The latter is found in the 
northern tier of States from Minnesota to Maine and in eastern Canada. 
The western larch (Larix occidentalis) is native to Montana, Idaho, 
Washington, and British Columbia. Both are needle-leaf trees, 
which annually shed their foliage.

BIRCH. 
While there are several species of birch in the United States, two 
furnish the bulk of the lumber produced and the species are seldom 
separated in the trade. Yellow birch (Betula lutea) is the principal 
source of lumber in New England, New York, and the Lake States, 
while sweet birch (Betula lenta) is the principal species cut in Penn- 
sylvania and West Virginia. The ranges of these species overlap and 
therefore each is cut toa small extent in the region where the other is 
most important. In northern New England paper birch (Betula 
papyrifera) is an important source of material for spools, toothpicks, 
and novelties, but a great deal is not cut into lumber. 
Sweet or cherry birch (Betula lenta) ranges from Newfoundland to 
western Ontario and southward into Indiana and Illinois, and among 
the mountains to Kentucky and Tennessee. It is sometimes known 
as wintergreen birch. 
Yellow birch (Betula lutea) has the same eastern range as the fore- 
going, but extends farther west and northwest. 
River birch (Betula nigra) ranges over the Southern Sines and is 
found in New England and New York. It is poorer in color and 
figure than the other birches, but is sometimes cut for lumber. 
Paper birch (Betula papyrifera) is confined to the northern tier of 
States east of Minnesota principally, and is very abundant in Michi- 
gan, Wisconsin, New York, New England, and Canada. 
Mountain birch (Betula occidentalis) is sawed in lumber to a moder- 
ate extent on the Pacific coast. 
White birch (Betula populifolia) is a minor timber tree in New 
England and farther northeast in Canada.
