COTTONWOOD. 
Cottonwood lumber is cut from a group of trees which are known 
under various names in the regions where they grow.. Among them 
are the common cottonwood, balm of Gilead, and aspen or popple, 
which are the most important east of the Reece. Mountains, and 
black cottonwood on the Pacific coast. } 
Common cottonwood (Populus deltoides) furnishes the bulk of the 
lumber. It is found in the whole country east of the Rocky Moun- 
tains and is lumbered in all parts of its range. 
Swamp cottonwood (Populus hetrophylla) is best developed i in the 
lower Mississippi Valley States, but it grows naturally in the Atlantic 
States and in the Ohio Valley. 
Aspen or popple (Populus tremuloides) is often designated as poplar 
in the Lake States, where much of it grows. It is found growing 
in various localities from Maine to California and far northward in _ 
British America. Saw logs cut from aspen are usually small. 
Large-toothed aspen (Populus grandidentata) is not usually dis- 
tinguished from the other. It ranges from Nova Scotia to Minne- 
sota and along the mountains to Tennessee and North Carolina. 
Balm of Gilead (Populus balsamifera) is commonly known as balm 
in the factory and lumberyard. Its range includes Maine and 
Oregon and most of the States between, and also a large part of 
British America. 
Western or black cottonwood (Populus trichocarpa) ranges near 
the Pacific coast from Alaska to southern California. It is the 
largest of the cottonwoods. 
Small quantities of lumber are cut from two foreign cottonwoods 
which have been introduced in this country, the white poplar (Popu- 
lus alba), also called silver and English poplar, and the black or 
lombardy poplar (Populus nigra).
