tained by looking in the column headed $.22 on the horizontal 

 line opposite 450 hours. If the number of hours on Field No. 2 

 is 456, an additional calculation is necessary, since the table 

 does not show a specific value for any hours between 450 and 

 460. In order to find the value of 456 hours at 22 cents, it is 

 necessary to find the value of 450 hours and add to it the 

 value of 6 hours, thus: 



450 hours at 22 cents, per table $99 .00 



6 hours at 22 cents, per table 1 .32 



456 hours at 22 cents for Field No. 2. . . $100.32 



For any number of hours over 500, the calculation may be 

 obtained similarly by adding the value for 500 hours to some 

 other value shown in the table, as the occasion demands. 



Feed Record Calculations. A feed record has very few types 

 of product to con>i(l-r as compared with the number of farm 

 elements to be considered in a labor record. Accordingly. 

 a Conversion table for recording values of the feed consunu'<l 

 by animals is not of much assistance. 1 The prices of the 

 products vary to such an extent that such a table would be so large 

 as to become unwieldy. A table is presented below, however, 

 which is designed to assist in calculating the number of bushels 

 of a product in a given number of pounds. That is, for in- 

 stance, if a notation of feedings is made in pounds during a 

 month, and it is desired to reduce the figure to bushels before 

 applying the average market price of the product, the Feed 

 Conversion table of Illustration 76 is used. The table can 

 also be used in connection with the sale of any of the ordinary 

 farm products, as it affords a quick and accurate means of 

 finding the number of bushels in a load when the weight in 

 pounds is given. The results are so tabulated that they can 

 be determined with equal rapidity for a product weighing 32, 

 48, 56, 60 or 70 pounds to the bushel. 



In the Feed Conversion Table of Illustration 76 all of the 

 possible weights are not given in detail. A sufficient num- 

 ber are given, however, so that almost any weight in pounds
