282 TIMBER AND TIMBER TREES. [CHAP. 



TABLE CL. YELLOW PINE (CANADA). 

 Transverse Experiments. yd Example. 



E = 650960. S = 1324. 



These experiments are similar 

 to the last, but the specimens were 

 taken from a larger tree, and the 

 soft wood about the pith, including 

 the heart-shake, was allowed to drop 

 out. In this case the woody layers 

 were placed vertically in the machine 

 for testing them transversely (Fig. 31). 

 The mean results of the transverse experiments are 

 as follows, viz. : 



The pieces i and I ', s.g. 543, broke with 505 Ibs. =622720. 8 = 1327
