THE WESTERN HEMLOCK. 



logs this discrepancy is iu part justified by the loss in slabs, but there 

 is no question but that on the whole a mill would gain more by cutting 

 to a 16-inch limit than is shown by Table 6. The average difference in 

 the merchantable length between cutting to 16 inches in the top and 

 cutting as it is now done is shown to be from 15 to 20 feet. 



The following table gives, on a basis of diameter breasthigh, the 

 total height, length of crown, and merchantable length of Hemlock 

 grown under cover and standing free:
