HOW TO USE TABLE Iil. 
The use of Table III can be well illustrated by examples. Given 
$2.50 as the value of 100 pounds-of barley, what is the corresponding 
value per bushel? Look for $2.50 in column headed “‘ Value per 100 
pounds, barley.’’ Opposite this value in column “‘ Value per bushel” 
is given the corresponding value of barley per bushel, which is $1.20. 
RELATIVE VALUE OF FEEDS. 
The selling price of a feed is not a reliable guide to its relative 
feeding value. The carbohydrate feeds (corn, oats, barley, kafir, 
and various others) and the protein feeds (cotton-seed meal, tank- 
age, and brewers’ grains) are found on the market at various prices. 
The feeder wants to know, with certain given prices, ‘“‘ What is the 
cheapest feed to buy—what is the true value of a bushel of oats, rye, 
or barley for feed when corn is worth 80 cents a bushel, or what is 
the value of a ton of brewers’ grains, linseed meal, or bran when 
cotton-seed meal is worth $30 per ton and corn a dollar a bushel?” 
In the following pages there are presented tables, by the use of which 
these questions can be answered. 
RELATIVE VALUE OF PROTEIN FEEDS. 
In localities in which the cheapest and most available feeding 
stuffs are deficient in protein and where, in consequence, it 1s neces- 
sary to buy nitrogenous concentrates as a means of balancing the 
ration, the feeder’s problem is to obtain the needed protein with the 
smallest possible outlay of money. The method here outlined 
shows how this may be done.
