TABLE XLIY. 



SlIOWS THE SOLID CONTENT OP 1 FOOT IN LENGTH, OP CYLINDRICAL | 

 TREES, ETC., AT GIRTHS, OR CIRCUMFERENCES, FROM 1 FOOT 4 

 INCHES, TO 12 FEET 9 INCHES. 



THE Table is divided into 3 double columns, each having the 

 girths in feet and inches on the left hand ; and immediately oppo- 

 site each girth is found the content of 1 foot in length, at that 

 girth, in cubic feet, and decimals of a foot. 



To find the content of a tree by the Table. Take the girth of 

 the tree in feet and inches, from which deduct from 2 to 4 inches 

 for the thickness of the bark ; find the remainder of the girth in 

 the left-hand column of the Table, and multiply the number op- 

 posite by the length of the tree in feet ; point off three places of 

 figures on the right hand of the product, the figures on the left 

 are cubic feet; multiply the figures pointed off by 12, and from 

 the product again point off three places of figures on the right, 

 the figures on the left are solid inches, or slices 1 foot square and 



1 inch thick ; the remainder may be again multiplied by 4 and 

 treated in the same manner for quarters of an inch. 



EXAMPLE. 



"What is the solid content of a tree 15 feet in length, and girth 

 it the one end 128 inches, at the other 96 inches, after deducting 



2 inches for the bark ; giving a mean girth of 112 inches. 



On referring to the Table, opposite the girth 



112 inches = 9 feet 4 inches, stands . . G.932 



Which multiply by the length , 15 



34660 

 6932 



Point off three places for feet . . . 103.980 

 Multiply the remainder by ... 12 



Point off three places for inches . 11.7GO 



Multiply the remainder by , , , 4 



Which gives 3 quarters of an inch . . 3.040 

 Making the content 103 feet, 11-| inches.
