Example 1. — Required the number of loads neces-sary to ma- 

 nure an acre of ground, dividing each load into six heaps, and 

 placing them at a distance of 4 V j'ards from each other. The an- 

 swer by the table is 39f . 



Example 2. — A farmer has a field containing 5^ acres, over 

 which he wishes to spread 82 loads of dung. Xow 82 divided by 

 5^, gives 15 loads per acre ; and by referring to the table, it will 

 be seen that the desired object may be accomplished by making 

 4 heaps of a load, and placing them 9 yards apart, or by 9 heaps 

 at 6 yards, as may be thought advisable.
