TABLE IX. 



SHOWING THE WEIGHT OF GROWING PRODUCE PER IMPERIAL, SCOTCH, 

 AND IRISH ACRE, HAVING THE WEIGHT GIVEN, OF PRODUCE GROWN 

 ON PORTIONS 1 YARD IN LENGTH, AND FROM 9 INCHES TO 1 YARD 

 IN BREADTH, AT RATES FROM ^ OUNCE TO 21 POUNDS PER YARD. 



DESCRIPTION OF THE TABLE. 



THE weight per yard is found in the left hand column of the 

 Table, rising by \ ounce to 4 ounces, thence by J pound to 1 pound, 

 and thence by J pound to the end of each dimension in the 

 Table. In the columns to the right hand, opposite any given j 

 weight per yard, under their respective denominations, is found ' 

 the weight per Imperial, Scotch, and Irish acre, in tons, hundred- 

 weights, quarters, and pounds. At the top of each dimension or 

 breadth in the Table is stated the number of yards in length 

 of that breadth which are contained in an acre. 



In order to get a fair average weight per yard to use with the 

 Table, it will be necessary to measure off 6 or 8 yards, and find 

 the weight of the produce thereon, which must be divided by 

 the number of yards measured off, to give the average weight 

 per yard. If the crop on the land seems to be unequal, several 

 parts of the field may be treated in the manner above mentioned, 

 the whole weights being added together, and divided by the 

 whole number of yards, which, if gone about correctly, may now 

 be considered a fair average weight per yard. It must be kept 

 in mind, that a small error in the weight of the average yard, 

 either over or under, becomes considerable, when multiplied, as 

 it will be, into every yard in the acre. In measuring for the 

 average of turnips, cabbages, and other plants in drills or rows, 

 care must be taken to begin and end the measurement in the 

 middle of the space between the first and last plant. 



To find the average weight of each turnip, cabbage, <fcc., weigh 

 any number taken from the row or drill, in succession and with- 

 out selection, and divide the weight by the number; the quotient 

 is the average weight of each. 



To find the number of turnips or plants of any kind on an 

 acre, ascertain the number on a yard at any of the dimensions 

 in the Table, and multiply that number by the number at the 

 top of the Table of the given dimension ; the product is the 

 number of plants, <fec., per acre. If there is only one plant per
