TO FIND THE NUMBEB OF HEAPS WHICH WILL BE BE- 

 QUIBED FOB MANUBIN& ANY QUANTITY OF LAND, THE 

 HEAPS AND BOWS BEING OF AN UNEQUAL DISTANCE. 



RULE. Reduce the distance of the heaps, the distance 

 of the rows, and the quantity of land, all to the same de- 

 nomination ; then multiply the distance of the heaps by 

 the distance of the rows, and divide the quantity of land 

 by their product. 



Ex. How many heaps will be required for 8 acres, the 

 heaps being 4^ yards distant and the rows 7 yards ? 



8 acres equal to 38720 yards, or 8 acres = 50181120 inches. 



Dist. of heaps 4| 4| yds. = 162 inches. 



Dist. of rows 7 7 yds. = 352 inches.

40824)501811 20(1229if heaps.

To find the number of Heaps, as above required, from 

 the Table : Look in the left hand column for the dis- 

 tance of heaps, and in the upper line (large figures), for 

 the distance of the rows; directly under the latter, and 

 opposite to the former, is found the number of heaps which 

 will be required for one acre at the above-mentioned dis- 

 tances, which number (153.65), multiplied by the number 

 of acres (8), gives 1229.2 heaps ; nearly the same as above.
