posed and made over into plant food than those of the solid 

 .excrements, therefore are more valuable. Now, while not over 50 

 per cent, of the nitrogenous substances contained in straw would be 

 digested, as much as 85 per cent, of the same compounds in corn meal 

 would pass through the process of digestion. A larger per centage of 

 the nitrogen of the latter would therefore be found in the urine, conse- 

 quentlj ten pounds of that element as existing in manure produced 

 by corn would be more valuable than the same quantity in manure 

 made from ha3\ In general, it can be said that the valuable con- 

 stituents of the excrements from concentrated cattle foods have a 

 higher value, pound for pound, than do those from coarse fodder. 

 However, in calculating the money value of manure made in 

 the various waj'S these differences cannot easil}' be taken into 

 'account. "We will take the above-mentioned price of the nitro- 

 gen of fish as a basis for calculation. Soluble phosphoric acid is 

 worth 12| cents per pound. Only a portion of that even in 

 well rotted manure is soluble, so that 9 cents may be assumed as a 

 fair price for the phosphoric acid of stable manure. The alkalies 

 are to quite an extent soluble, as they go out largely in the urine, and 

 can probably be considered as worth 4 cents in the total excrement. 

 The mone}- values given in the following table ai-e calculated on 

 the basis given above, viz : 80 per cent, of the nitrogen, and 95 

 per cent, of the phosphoric acid and potash of the food are consid- 

 ered as passing into the manure, these three ingredients being 

 estimated as worth 20, 9, and 4 cents per pound, respectively. 

 From the values thus obtained 20 per cent, is deducted on account 

 of gi-eater bulk and larger dilution of farm compared with com- 

 mercial manures. The greater bulk causes more expense in 

 handling, and the dilution causes slower action, the returns from 

 invested capital not being so immediate as is the case with concen- 

 trated fertilizers.
