TABLE XLVI. HEMLOCK * BARK. VOLUME IN STACKED 

 CORDS, VERMONT. 



1 Taken from "Hemlock in Vermont," by A. F. Hawes, State forester; Vt. Agr. Exp. Sta., 

 Bulletin 161 (January, 1912), p. 8. The table was constructed by "subtracting the volumes of 

 the trees inside the bark from their volumes outside the bark, and multiplying by 0.4, on the 

 assumption that 40 per cent of an average stacked cord of bark is solid bark." The accuracy of 

 this factor (taken from Schenck's " Forest Mensuration," 1905, p. 14) was borne out by investi- 

 gations of a few piles of bark.
