in the station bulletins or for prosecution of the case if it appear that the law has 

 been violated. 



"Under the new law the estimated value per ton is not given on the tag. It was 

 thought best to leave it off for two reasons — first, because the ingredients of which 

 fertilizers are made vary in price from time to time luring the year, and as the tags 

 are good for a year, or until used, the estimated value might not represent anywhere 

 near the true valuation during a portion of the year, at least ; and. second, because 

 it is much more important that the farmer should buy on the percentage of phos- 

 phoric acid, nitrogen, and potash in the fertilizer than on the estimated value."

 Emj., 26, pp. 5S0-59S; abs. in Tech. Quart., 11 (1S9S), No. 2, Rev. Chem., p. 51).— A 

 detailed account of unworked deposits. Analyses of the phosphatic nodules show 

 from 22.62 to 33.86 per cent of phosphoric acid. 



Fertilizer inspection, C. D. Woods, J. M. Bartlett, et al. (Maine Sta. Hid. J.:, 

 pp. S). — This bulletin contains the analyses of 125 manufacturers' samples of ferti- 

 lizers licensed before February 25, 1898, with a brief summary of the chief provi- 

 sions of the State fertilizer law. 



The cost of plant food in Connecticut, spring months of 1898 ( Connecticut State 

 Sta. Bui. 127, p\>. 10). — This bulletin contains a schedule of trade values of fertiliz- 

 ing ingredients for 1898; notes on the purchase of fertilizers and on the cost of 

 nitrogen in nitrate of soda, sulphate of ammonia, dried blood, cotton-seed meal, and 

 castor pomace; phosphoric acid in dissolved boneblack and acid phosphate, and 

 potash in high-grade sulphate, double sulphate of potash and magnesia, muri- 

 ate of potash, carbonate of potash, and cotton-hull ashes; and analyses of 7 samples 

 of fertilizing materials, including mixed fertilizers, bat guano, rape-seed meal, and 

 street sweepings. Determinations of the solubility of the organic nitrogen of 5 of 

 the fertilizers in pepsin solution are also reported. 



Analyses of commercial fertilizers, T. J. Edge and W. Freak {Pennsylvania 

 Dept. Ayr. Bui. 37, pp. 40). — This bulletin gives the text of the State fertilizer law, 

 notes on valuation, and tabulated analyses and valuations of 591 samples of fer- 

 tilizing materials inspected during the period from January 1 to August 1, 1898. 



Analyses of commercial fertilizers, M. A. Scovell, A. M. Peter, and H. E. 

 Curtis (Kentucky Sta. Bui. 71, pp. 115-123). — This bulletin gives the trade values of 

 the essential fertilizing ingredients for 1898, which are the same as those for 1897, 

 and tabulated analyses and valuations of 34 samples of fertilizers examined since 

 the publication of Bulletin 68 of the station (E. S. E., 9, p. 338). 



FIELD CROPS. 



Experiments with different kinds of fertilizers in 1896 on the 

 Kazan Experimental Farm (tielsk. Khoz. i Lyesov., 185 (1897), May, 

 pp. 263-282). — Experiments were made with rye, oats, potatoes, arid 

 clover with timothy for hay. 



Rye. — Three series of experiments were made with rye. The object 

 of the first series was to study the influence on the yield of rye of the 

 following fertilizers: (1) Barnyard manure 35,600 lbs. per acre, (2) 

 barnyard manure with 416 lbs. of superphosphate, (3) green manure, 

 (4) green manure with 416 pounds of phosphate, (5) green manure with 

 416 lbs. of potash, (6) green manure with 356 lbs. of Berliner's bone 

 meal A (4.5 per cent of nitrogen and 24 per cent of phosphoric acid), 

 and (7) green manure with 178 lbs. of Berliner's bone meal B (0.6 per 

 cent of nitrogen and 31 per cent of phosphoric acid). The plats, 0.45 

 acres each, were sown in 1890 under clover with timothy. The tabu-
