Example 1. Required the number of loads necessary to ma-

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

 5fj 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.
