pounds of digestible protein, 42.9 pounds of digestible carbo- 

 hydrates, and 1.3 pounds of digestible fat. We will count the 

 fat in the usual way, although it does not amount to much. 

 Converting that into carbohydrates by multiplying by 2^ gives 

 us 2.9, and then if we add it to the 42.9 pounds carbohydrates 

 we have 45.8 pounds equivalent carbohydrate material. We 

 will assume that the digestible protein in hay is just as valuable 

 as the protein in cottonseed meal or in corn meal, and call it 

 worth 2.7 cents per pound. The 4.7 pounds in one hundred 

 would then be worth about 12.7 cents. 



• It is rather difficult to make a guess at the price of hay. Good 

 hay is worth $18 perhaps in the markets, and you may call it 

 $12 at the bams. Let us call it $15. In fact few men if any 

 ought to sell any hay. Suppose a man sells $500 worth of hay, 

 and promises that he will buy back $500 worth of fertility; he 

 does not do it. I know a man who loves to play solitaire. I 

 have watched him play, and I never saw him play a game with- 

 out cheating himself. The most of us when we go to selling 

 hay and buying fertilizer are like my friend. 



We will assume that the hay is worth $15 a ton or 75 cents 

 a hundred. The protein in it is worth 12.7 cents, according to 

 our figures above, which leaves the cost of the carbohydrates 

 in the hay as 62.3 cents per 100 pounds of hay, and that will 

 make it about i 1-3 cents per pound. That is, the carbohydrates 

 which we buy in com cost 1.8 cents per pound, and those which 

 we produce in hay are worth about i 1-3 cents per pound. That 

 is pretty nearly the difference in value, but the cow has more 

 work to get them from the hay than from the more easily 

 digested concentrates. 



We may then settle ourselves down to three prices: Digest- 

 ible protein, 2.7 cents per pound ; carbohydrates in concentrates 

 such as corn meal, etc., 1.8 cents, and in hay i 1-3 cents per 

 pound. 



THE COMPARATIVE MONEY VALUES OF DIFFERENT KINDS 



OF HAY. 



If you have followed me and accepted my argument thus far, 

 you will agree that we have here a means whereby we can go 

 into the market and look over the feeding stuffs and see whether 

 we get our money's worth or not, and where we can spend
