* Example. — A Red Pine joist 11 feet long, H'Ol in. by 3 in., with 512 lbs. weight to the 
foot, uniformly loaded, deflects in the middle of an inch ; and 5-25 times that weight is 
the breaking weight of the same. 
*** When the breadth exceeds 3 inches, or the weight exceeds 561-5 its. to the foot, the 
Scantlings may he found by the First Series op Tables, of which this and the 
six preceding tables form, by interpolation, a part.
