38 BOARD OF AGRICULTURE, 



the (liflV'iviice in feeding for diffovont purposes. Let us determine 

 through the conipiuison of these figures upon the chart, the differ- 

 ence that will occur between the selling of the I'aw products, in a 

 serix'S of years, and the selling of the resulting products. A ton of 

 fat beef, live weight, contains fifty pounds of nitrogen. Suppose 

 you are realizing the money for your crops through the making and 

 selling of fat beef. If you sell a ton of English ha}' you sell thirty- 

 one pounds of nitrogen. If you sell a ton of fat beef, live weight, 

 you sell only fifty pounds of nitrogen ; only about fifty per cent, 

 more in a ton of live weight of i;it beef than there is in a 

 single ton of P'nglish hay ; and yet tiiat represents the amount of 

 fertilizing material that j'ou remove when that ton of live beef goes 

 from the farm. A ton of fat mutton shows still better; only fort}-- 

 four pounds of nitrogen is removed with a ton of fat mutton, twentj'- 

 two pounds of phosphoric acid, and two pounds of potash. A ton 

 of fat swine removed from the farm carries away only thirty-four 

 pounds of nitrogen, just about the amount that is removed b}- selling 

 one ton of English hay ; yet the ton of English hay is sold for 

 twelve dollars, and the ton of fat swine for one hundred and sixty. 

 There is sold only about the same amount of fertilizing raateiial 

 with this one hundred and sixty dollars worth of fat swine that goes 

 with a single ton of English hay. With butter, it Is seen, the 

 showing is still better. 



Let us understand the philosophy of that. AVhy is it that so little 

 of fertilizing material goes with the fiit hogs when sold from the 

 farm ? Look at the philosophy of it and you will see at once. There 

 is but little bone structure compared to the full weight of the fat 

 hog, and consequently there has been but little phosphate of lime 

 used in making up this growth. There is but little of lean meat, 

 and consequently there has been but little of nitrogenous material 

 stored up there. Far the greater part of it is fat, and this fat comes 

 from the atmosphere, and you have nothing to do with it. Hence 

 you see but very little fertilizing material goes from the farm when 

 your pig is taken away. 



With butter practically speaking there is nothing of a 'fertilizing 

 nature that goes with it when it is sold from the farm. The butter 

 itself like all of this fatty material, comes from the atmosphere, and 

 when sold from the ftarm it carries only that material with it. In 

 carrying on a butter dairy practically all the fertilizing material is
