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



from e ih other in every direction, but it will be easy, from the 

 Table, to find the number of plants required for a given piece of 

 ground, when the distance between the rows or drills exceeds the 

 distance between the plants in the row. 



For example, if the width between the rows is twice the dis- 

 tance between the plants in the row, divide the number found in 

 the Table by 2 ; if 3 times the distance, divide by 3, and so on 

 with any other required proportion. Or, the number may be 

 found for the width between the rows, and if the distance between 

 the plants in the row is \, or ^, or J, &c., multiply the number 

 found by 2, 3, or 4, as the case may be. If a proportion cannot 

 be conveniently taken, proceed by the following Rule : 



RULE. First find from the Table the number of plants that 

 would be necessary for the given piece of land, at the given dis- 

 tance of the plants from each other in the rows or drills ; then 

 multiply the number thus found by the same distance, and divide 

 the product by the given distance between the rows, the quotient 

 is the number of plants required. Or, find from the Table the 

 number of plants that would be required for the given width be- 

 tween the rows, ,then multiply this number by the same width, 

 and divide the product by the given distance between the plants 

 in the rows, the quotient is the number of plants required. 



EXAMPLE 3. How many potato sets are required to plant a 

 field, measuring 1 acre, 36 poles, the distance between each set 

 being 9 inches, and the width of the drills 30 inches? 

 Look in the Table for 9 inches, the width between 

 each set in the row, under which, 



And opposite 1 acre, is 77440 



And opposite 36 poles, is 17424 



94864 

 This multiplied by the distance in the row . 9 



And the product, divided by the width of the rows, 3,0)85377,6 



Gives the number of sets required = 28459/0 



For an exercise, the solution of the same question may be 



shown by taking the width between the rows from the Table. 



Thus 



Under 30 inches, and opposite 1 acre, stands . , 6970 

 And opposite 36 poles, stands . . 1568 



This multiplied by the width of the rows = . 30 



And the product divided by the distance between 



the sets in the row .... 9)256140 



Number or sets required, 28460
