$1.25 a ton. This does not include the cost of hauling it to the field. 

 Manure was credited to cattle on each farm at this rate. The credit was 

 then apportioned to cows, to heifers, and to herd bulls, according to the 

 average inventory of cattle units. No attempt was made to calculate

the value of manure on the basis of rations fed, for the reason that other 

 factors have an equal, if not greater, influence. Neither was it considered 

 practical to vary the credit to different classes of stock on the basis of 

 the composition of the rations. The value of manure was $9.66 per cattle 

 unit. This was u.i per cent of the total returns from cattle. 

 The data for manure recovered are given in table 22.

Miscellaneous returns 



Two farms received $157 for hauling neighbors' milk, three farms 

 received $52 for boarding cattle, and fifteen farms received $142 for the 

 use of herd bulls. These receipts were included under miscellaneous 

 returns and represented 0.2 per cent of the total returns from the enter- 

 prise. The figures for miscellaneous returns are given in table 23 :
