To find the number of plants required to set an acre, multiply 

 together the two distances, in feet, at which the trees stand 

 apart, and divide 43,560 by the product; the quotient will be the 

 number of plants required. 



Quincunx Planting. — To find the number of plants required 

 to set an acre by the quincunx method, ascertain from the above 

 tables the number required at the given rectangular distances, 

 and then increase the number by one-half.
