302 TABLE VII. NO. OF TREES, ETC., REQUIRED TO PLANT LAND. 



It i*"iy be observed, that the above operations would be 

 shortened by reducing the multipliers and divisors to their 

 lowest terms ; thus, for 9 and 30 inches, 3 and 10 may be used ; 

 and for 12 and 28 inches, 3 and 7 may be used, with the same 

 results as above. 



To find the number of plants, trees, &c., required for any piece 

 of land by calculation. 



RULE 1. When the plants, &c., are to be at equal distances from 

 each other. Reduce the given piece of land to the same deno- 

 mination as the given distance between the plants, and divide 

 the numbers so found by the square of the distance, the quotient 

 is the number of plants required. 



2. When the plants, &c., are in rows or drills, the width be- 

 tween the rows or drills being greater than the distance between 

 each plant in the drill. Reduce the given piece of land to the 

 same denomination as the given distances ; multiply the distance 

 of the plants in the drill by the width of the drill, and divide the 

 land, reduced as above directed, by the product, the quotient is 

 the number of plants required. 



Take for illustration the 1st and 4th examples given above : 



1. What number of cabbages are required to plant 1 acre, 3 

 roods, and 35 poles, of land, at a distance of 30 inches?
