* EarampZe.— Red Pine 15 feet long, .... 14-95 in. by 2^ in., or 14-07 by 3, or 13-37 
by 3i or 12-78 by 4, or 12-29 by 4i, or 11-87 by 5, with 56-50 cwts. uni- 
formly loaded, or 35-31 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 15 feet long 12-29 in. by 4^ in. is 6-417 x 56-5 = 
362-5 cwts. uniformly loaded, or 5-133 x 35-31 = 181-2 cwts, suspended from the middle.
