PRODUCTION OF LUMBER^ LATH^ AND SHINGLES. 



19 



White pine {Plnus strohus) is the familiar white pine of the Lake 

 States, the Northeast, and the Appalachian region, 



Norway (or red) pine {Plnus resiiiosa) is lumbered in the Lake 

 States and farther east. Botanically it is a yellow pine. The better 

 grades are often sold with white pine, but the wood also has a 

 market under its own name. 



Jack pine {Pinus banksimia) is a small tree of the Lake States, 

 and is used to a limited extent. 



Western white pine {Pinus monticola) ^ sometimes called silver 

 pine, supplies the white-pine lumber cut in Idaho, Montana, Wash- 

 ington, and to a limited extent in Oregon.

HEMLOCK. 



Hemlock {Tsuga canadensis)^ the eastern hemlock, is lumbered in 

 the Lake States, the Northeastern States, and the Appalachian re- 

 gion. Western hemlock {Tsuga heterophylla) is the main source of 

 hemlock lumber in the Northwestern States, and its production is 

 increasing. Although the mill value is lower, it is superior to the 

 eastern hemlock, and is often sold with Douglas fir. The western 

 mountain or black hemlock {Tsuga mertensiana) and the Carolina 

 hemlock {Tsuga caroUniana) of the Appalachian region are only 

 occasionally lumbered.
