production of labor or of farm products, is of interest to every 
_ farmer and may be of great value in increasing the profits of the 
farm. . 
During the past quarter of a century the development of those 
large manufacturing interests of the country which depend for 
their raw material upon one or another of our agricultural 
products, has placed at the disposal of the farmer a large quan- 
tity of various waste products so that in addition to the bran, 
shorts and middlings of the various grains used by the flouring 
mills, we have cotton-seed and linseed meal, gluten meal from the 
glucose and starch factories, malt sprouts from the maltsters, 
brewers’ grains and distillery refuse from the manufacturers of 
beer and whiskey, and many other similar products of varied 
composition, and nearly all of them of very high feeding value. 
While, therefore the feeder has at his disposal so large a number 
of products, so great is the diversity in their composition that 
there is need of increased intelligence as to the function of the 
several food constituents in order to secure the greatest economy 
in feeding, as also for the purpose of maintaining the animal in 
full health and vigor. 
It is notorious that so often is our leading cereal corn, a food 
of acknowledged value, injudiciously fed, and so often have 
disastrous if not fatal results followed such injudicious use, that 
by some it has come to be regarded as only adapted to swine and 
poultry feeding, dangerous for horses and useless for cows; but 
equally unfortunate results have followed the use of several of 
the highly concentrated food products of the manufactories by 
those who were unfamiliar with the composition and nature of 
the material and the necessary precaution to be observed in its 
use. 
_ COMMERCIAL AND Food VALUATION OF VARIOUS FEEDING STUFFS. 
Having been thrown upon the market as refuse products of 
manufacture, as we have seen these materials to have been, their 
price was governed at first by the demand which their use 
created without much, if any, reference to their actual or relative 
feeding value or to any cost of their production; but, so extensive 
has become their use, and so generally acknowledged their feed- 
ing value, that their market value has risen greatly with the 
- Increased demand, and they have now, in many cases, become one 
_ of the sources of profit to the manufacturers producing them.
