11, or 11-27 by 12, or 10 97 by 13, or 10-70 by 14, or 10 46 by 15, with 112 35 cwts. 
uniformly loaded, or 70'22 cwts. suspended from the middle, deflects -L^ of an inch. 
The breaking weight of Red Pine 17 feet long, 14 in. by 14 in., is 8-783 x 146-92 = 
1290-4 cwts, uniformly loaded, or 7'026 x 91-83 = 645-2 cwts. suspended from the middle.
