This represents a square acre of orchard set on the 30 feet square plan, 

 with blasts between the trees. This system is best where trees are from 20 

 to 30 feet apart.

This represents a square acre of orchard set on the 40 feet square plan, 

 with blasts on three sides of each tree. The holes are punched at the apexes 

 of an equilateral triangle, the tree being in the center and the apexes at 10 

 feet distances from the tree. As shown, the triangles for two adjacent rows 

 should point in opposite directions to distribute the blasting to best advantage. 

 This method is best when trees are more than 30 feet apart.
