970 EXPERIMENT STATION RECORD. 



pyridin bases, ■5\liich are considered to be not only of little fertilizing value, but 

 positively poisonous to plants. It is recommended, therefore, that the valuation of 

 soot can be based on its animoniacal nitrogen and not on its total nitrogen. 



Analyses of commercial fertilizers, M. A. Scovkll, A. M. Petek, and 11. E. 

 Curtis {Kentucky Sfa. Bui. 65, pp. 99-108).— Analyses and valuations of 52 samples of 

 fertilizing materials are tabulated. 



Inspection of fertilizers, C. D. Woods, J. M. Bartlett, and L. H. Merrill 

 {Maine Sla. lUiL .T>, pp. 33). — Notes on valuation and tabulated analyses of 142 sam- 

 ples of fertilizers. 



Analyses of commercial fertilizers, W. L. Hutchinson {State Chemist Missis- 

 sipjii liul. 13, 2)p- I--). — Analyses of 39 samples of fertilizers are reported, and a state- 

 ment of guaranties of manufacturers during the season of 1896-'97 is given. 



Report on the enforcement of the fertilizer control law, H. J. Waters {Mis- 

 souri Sta. Bui. 34, pp. 1-9). — A detailed statement of receipts and expenditures by 

 the fertilizer control of the station, with notes on valuation and on the extent of 

 the fertilizer trade in Missouri. According to what are considered conservative esti- 

 mates, "the total consumption of commercial fertilizers in the State in 1896 was 

 2,000 tons/' representing, at an average cost of $25 per ton, a total investment by 

 the farmers of Missouri of $50,000. These fertilizers were used almost entirely "in 

 the two tiers of counties on the eastern border of the State and in a few counties in 

 southwest Missouri." 



Fertilizer analyses, H. B. Battle {North Carolina Sta. Special Buls. 40, pp. 3-12; 

 41, pp. 17-29; 42, pp. 33-50; 43, pp. 55-75; 44, pp. 79-103; 45, pp. 107-134).— These 

 bulletins include abstracts of the State fertilizer law, explanations of terms used in 

 stating analyses, notes on valuation, freight rates, and tabulated analyses of 715 

 samples of fertilizing materials. Commencing with Bulletin 40 a new plan of stat- 

 ing analyses is inaugurated. " It consists in omitting theexact figures of the analysis 

 of the fertilizer when they are up to or above the guaranty made by the manufac- 

 turer. If the jiercentages, as found by analysis, are lower than those guarantied by 

 the manufacturer, then the exact figures are given. " 



Commercial fertilizers, ,T. L. Hills and B. O. White {Vermont Sta. Rpt. 1S95, 

 l)p. 17-34).— An abstract of Bulletins 45, 46, and 47 of the station (E. S. R., 6, p. 980; 

 7, pp. 112, 196). 



Analyses of fertilizers, .1. L. Hills and B. O. White {Vermont Sta. Bpt. 1S95, 

 pp. 37-40). — Analyses and valuations of 54 samples of fertilizing materials, iucluding 

 mixed fertilizers, ashes, and muck are reported. 



FIELD CROPS. 



Miscellaneous fodder crops, J. L. Hills ( Vermont Sta. Rpt. 1895, 

 pp. 194-302). — A record is given of the growth, yield, and composition 

 of the following crops grown on experimental plats : Japanese millet, 

 Hnngarian millet, cowpea, soja bean, flat pea, vetch and oats, Bokhara 

 clover, crimson clover, alsike clover, white clover, wild vetch, and oats 

 and peas. The yield of nntrients is calculated for each crop. 



"The [cow] ])eas were planted in early .Tune (to avoid the possibilities of early 

 frosts), and harvested (Jctober 1, the tops being just barely touched by frost. Seed 

 was well formed but not ripened on the Extra Early and Calico varieties. These 

 two varieties also made the best growth and richest fodder. Judging from but a 

 single year's experience, the cowpeas presented no advantage over soja beans except 

 that of growing, in two cases, slightly richer fodder. 



"The yield of dry matter was at best less than half, and the yield of i)rotein less 

 than two-thirds those given on the soja-bean plats. The latter crop grew with
