Mechanical Properties of Western Hemlock. By O. P. AI. 

 Goss. Bulletin 115, U. S. Forest Service. Washington, D. C. 

 1913. Pp. 45. 



Based on Forest Service tests of green stringers of all grades, 

 assuming Douglas fir to have a strength value of 100, western 

 hemlock has a strength of 88 and western larch a strength of 

 81.7. Although there is a prejudice against the name "hemlock," 

 manufacturers often mix it with Douglas fir and it is sold and 

 used for the same purposes. It makes excellent barrels and 

 boxes for shipping food stuffs, and is recommended for edge- 

 grain flooring, interior finish, and framing. A large future de- 

 mand for it is predicted.
