amounts in the aggregate to 2,787 up to November 1, 1890 aL 
the aggregate cost of their rations amounts to $299.21, 
If now we assume that the proportionate value of the nitro, 
compounds recovered in the manure from these steers was eqt 
to aa sae secured in the experiments with the cows alres 
of an actual 5412 pounds, as shown by analysis, thus leaving 
overplus of 4883.5 pounds to be accounted for, and as four-twent; 
fifths of this is nitrogen, we have 781.4 pounds, which, at ninet 
cents per pound, the valuation we have placed upon it througheae 
amounts to $148.46, which very closely agrees with the amou 
estimated from our ete with the cows already reporte 
most of which were received as calves, are of value. The jee a 
have been tabulated for each animal from the time it was receivec 
at the Station up to the time of dropping a calf, and in the ot Ne 
cases up to September 1, 1890. The record includes four heifers — | 
each of Holsteins and Ayrshires, two each of Guernseys : : 
American Holderness and three J erseys. .
