TABLE XIII. 



SHOWING THE NUMBER OP C UlT- LOADS OP MANURE REQUIRED FOR 

 AN ACRE, LAID DOWN IN HEAPS FROM 2 TO 20 IN A CART-LOAD, 

 AND FROM FEET TO 24 FEET DISTANT FROM EACH OTHER. 



DESCRIPTION OF THE TABLE. 



IN the left-hand column of the page is placed the distance from 

 each other at which the heaps are to be laid down, rising by a 

 half foot from 6 feet to 12 feet or 4 yards, thence by 1J feet or 

 J yard, to 24 feet or 8 yards ; and along the top of the columns 

 is placed the number of heaps proposed to be made out of each 

 cart-load, rising from 2 to 20 ; under which, respectively, is 

 found the number of cart-loads required for an acre, at any of 

 the opposite distances in the left-hand column. 



EXAMPLE 1. How many cart-loads are required to manure an 

 acre, laying down the heaps at 2J yards from each other, and 

 dividing the load into 18 heaps ? 



Find 7J feet, or 2J yards, in the left-hand column, opposite to 

 which, under 18 heaps in a load, is found 43, the number of cart- 

 loads required. 



EXAMPLE 2. It is proposed to manure land at the rate of 40 

 cart-loads per acre, laid down at distances of 3J yards, or 10 J 

 feet from each other ; required into how many heaps each cart- 

 load must be divided ? 



Find 10 J feet, the proposed distance of the heaps in the left- 

 hand column ; then look along the opposite columns until you 

 find the nearest quantity to 40, which is 39J, and on the top 

 of that column is 10, the number of heaps into which each load 

 is to be divided. 



To manure land at the rate of a certain number of cubic 

 yards per acre, multiply the proposed number of cubic yards by 

 the number of cart-loads in a cubic yard, to reduce the cubic 

 yards to cart-loads, with which proceed as in the last example. 



This Table being calculated on the principle that the heaps 

 are placed at equal distances from each other, it may be neces- 

 sary to show the method of ascertaining the quantity of manure 

 required, when the distances are greater one way than the other. 



RULE. Find the quantity for one of the distances by the 

 Table, then multiply the quantity thus found by the same dis- 

 tance, and divide the product by the other distance. The quotient 

 is the quantity required. 



EXAMPLE 3. How many cart-loads of manure will be required 

 for an acre ; the distance between the heaps one way is 4 J yards,
