TABLE XIV. CONTENT OF MANURE HEAPS, ROAD METAL, &C. 34.1 



To calculate the above by the pen, 



Multiply the mean length GO feet 



By the mean breadth 15 feet 



300 

 60 



900 

 And this product by the mean depth 4 J feet 



3600 

 450 



Which divide by the solid feeH 27) 4050 (150 solid yards, 

 in a yard. / 27 as above.

EXAMPLE 2. The mean breadth of a dungpit is. 30 feet, the 

 mean length 50 feet, and the mean depth 2 feet 6 inches ; re- 

 quired the content in solid yards ? 



Find 30 feet, the breadth on the top of the page, and for tho 

 length 50 feet, take 40 feet and 10 feet, thus 



Opposite 40 feet and under the depth 2 feet yds. feet. 



C inches stands . . . 1113 



And opposite 10 feet stands . . 27 21 



Solid content 138 24 



EXAMPLE 3. Required the content in solid yards of a heap of 

 compost, the mean breadth being 8 feet, the mean length 75 

 feet, and the mean depth 2 feet 7 inches ? 



In this example take the length, 75 feet, in two parts, 60 and 

 15 feet, and the depth also in two parts, say 2 feet and 7 inches, 

 and having found 8 feet the breadth on the top of the page, 



yds. feet. 



Opposite 60 feet and under 2 feet stands 35 15 



And opposite 15 feet stands . . 8 24 



Then opposite 60 feet, under 7 inches, stands 10 10 

 And opposite 15 feet stands . . 216 



Solid content 57 11 



In adding up the sums in this example, we find the feet to bo 

 65, which, divided by 27, gives 2 yards to carry to the yards 

 column, and 1 1 feet over, which is set down.
