especially rich In protein Is not so neces- sary
 The shortage of coarse feeds and grains the last few years has been the means oi causing many feeders of live stock, psrticu- larly dairyInen. to consider the advisaoilty of purchasing certain of these mil b,- products for which heretofore they 1s had little use. Dairymea. too. are re- ognizing the fact that in order to secuE the best results from their cows they Inu-t feed a ration richer in protein than can. as rule. be compounded from the grains. hay and straw used the farm The by-prod- ucts best adapted 70 enrich the diet In pro- tein are the residues from the manufacture of some specific product from tne seed or grain, as for example. oil rom cotton seeo and naxseed. starch and sugar from corn. beer from barley. and flour from wheat, rye and buckwheat All these by-products. whien include cotton seed meal iinseed meal. dried brewers grains gluten meal, gluten feed. and the various kinds of bran mid6ings. etc. are very much richer in protein than the original seeds grains. because the substances extracted from them consist of fat, in the case of the first two. and of starch. or products rich in starch. in the case of the others. thus proportionsteiy in creasinR the protein in the residues. For this reason all of these byproducts have been found to serve an excellent purpose in the building up of rations; they are gen orally palatable and healthful, and. if judi ciously used do not contribute any undesir- able qualities to the products. beef or milk: besides they possess the further advantage in that in many cases. the cost of the ration is reduced by their use. Their intelligent purchase and economical use, however, re- quires that the purchaser shall possess a definite knowlege of their composition; that Is. he should know. first, not only how much protein and fat the genuine products, cotton seed meal. linseed meal gluten meal. gluten feed, bran and middiings contain. but also whether there is reasonable uniformity or wide variation in respect of these com pounds in the composition of the products Of the same kind or naEle secondly. whether any of them liable to be reduced in value by the addition of cheats. substances.
 We have found that in some eases there is a tendency to mix rasidues of one grain with another and sell them under trade name. to add low-grade by-Produets to those with which the farmer is familiar. as. for example oat huils to wheat bran. It is evident that the purchasers cannot form correct idea of the composition value of feed from the hsrne given it. and that steps should be taken to have these concentrated feeds sold in such manner that the per csntage composition. rather than name. will be the guide to their value. Laws have been passed making it compulsory for the seller of mill by products to print on the bag the guaranteed maximum percentage of protein and fat and the mininum percentage of crude fiber. and also the grains from which the feed twas made. In this way the farmer knows exactly what he is buying. and if he is fla miliar with the composition of his own feed stuffs and the requirements of the animals he is feeding. he can purchase his supply of concentrates intelligentiy and with every ss- surance that he is getting full value for his money. It will pay the farmer fin good hard cash to make thorough study of the whole subject of cattle feeding and to make him. self familiar with the nature of the various feedstuffs now in the market. in order that he may not only feed more economically. but that he may intelligently assist in the pro- curing of laws which make it possible for him to purchase feeds with a guaranty as to the amount they contain of the essential food constituents
