* Example.— Bei Pine 4 feet long, 1'26 in. by 1^ in., or I'SO by If, or I'lS by 2, 
or 1-10 by 2i, or 1-06 by 2i or 1-00 by 3, or "95 by 3|, with 32 lbs. uniformly loaded, 
or 20 lbs. suspended from the middle, deflects ^ of an inch. 
The breaking weight of Red Pine 4ft. long, 1-20 in. by 1| in., is 17-56 x 32 = 562 lbs. 
uniformly loaded, or 14-05 x 20 = 281 lbs. suspended from the middle. The breaking 
weight of Red Pine 5 feet long, 1-50 in. by If in., is 17"56 x 40 = 702 lbs. uniformly 
loaded, or 14-05 x 25 = 351 lbs. suspended from the middle: and so on, throughout tiie 
table.
