Commercial valuation of the food and fertilizing con- 

 stituents OF feeding materials, p. Collier, Ph. I), (pp. 4.S1- 

 497). — An extended popular discussion of the commercial value of the 

 food and fertilizing^ ingredients of dilferent feeding stuffs as estimated 

 on dilferent bases of valuation, and the relation of these values to the 

 ordinary selling i)rice, together with tabulated average analyses of ieed- 

 ing stuffs, and a statement of the average amounts of food and fertiliz- 

 ing ingredients in dairy products per ton.

Fertilizers, P. Collier, Ph. D. (pp. 499-551).— This bulletin 

 is in continuation of the series of popular fertilizer bulletins issued 

 by the station " for the benefit of the farmers of New York State." 

 The i)resent number treats of the different materials used in making 

 commercial fertilizers ; the fertilizing materials produced on farms ; the 

 fermentation, losses, and care of stable manure; and the influence of 

 kind and age of animals, and of food, on the manure. The bulletin 

 also contains tabulated analyses of 46 samples of commercial fertilizers 

 collected in the State during the fall of 1S90; and an extensive compi- 

 lation of analyses of fertilizing materials and the fertilizing ingredients 

 of farm products, taken from various sources. '

The production and care of farm manures, J. P. Koberts, 

 M. Agr. (pp. 29-42, plate 1, figs. 4). — This work is in continuation 

 of i)revious investigations as to the loss of fertilizing materials from 

 barnyard manure, published in Bulletin No. 13 of the station (see 

 Experiment Station Record, vol. i, p. 279). The conclusions arrived 

 at in these earlier experiments were as follows : 



Tli« results of one season's trial soeni to show that horse manure thrown in a loose 

 pile and sulijocted to the action of the olenionts, will lose nearly one half of its valu- 

 able fertiliziii}jf constituents in the course of G months; that mixed horse and cow 

 manure in a compact mass and so placed that .all water falling upon it quickly runs 

 through .and off, is subjected to a considerable, though not so great .a loss; and that no 

 appreciable loss takes place when manure simply dries. 



The two experiments here reported were on a larger scale than the 

 previous ones. (1) Two tons of loosely piled horse manure (3,819 poumls 

 excrement and G81 pounds wheat straw) were exposed in a well-drained 

 field from Ai)ril 25 to September 22, when it was scraped up, weighed, 

 and sampled for analysis. The season was very wet, the rainfall from 

 April to September amounting to 27.60 inches. The total weight 

 and the composition of the horse manure before and after exposure are 

 tabulated. From these analyses the total amounts of the fertilizing 

 ingredients in the fresh and exposed manure are calculated as follows :
