332 EXPERIMENT STATION RECORD. 



and nitrate of soda applied in different ways (all in one application or fractionally). 

 In general it was found that winter grain was less benefited by the fertilizers than 

 summer, the former producing a better crop without fertilizers than the latter. Both 

 for winter and summer fertilizing it is best to use a combination of sulphate of 

 ammonia and nitrate of soda. The results obtained in the use of fertilizers on one 

 grain are not considered applicable to another. 



The uses and abuses of fertilizer formulas, 8. ]M. Tracy {Proc. Soc. Prom. 

 Agr. Sci, 1900, pp. 164-1H8). — The unreliability of the fertilizer formujas commonly 

 recommended and of the need of care in ]ire])aring formulas for fertilizers for special 

 purposes are pointed out. 



The manurial value of ashes, mucks, seaweed, and bone, C D. AVoods 

 [Maine Sta. Bui. 74, pp. Go-St"^). — A popular discussion of the fertilizing value of these 

 materials, accompanied by compilations of analyses of wood ashes, mucks, and 

 seaweeds. 



Seaweed as a fertilizer, F. W. Moore (New Hampshire Sta. Bui. 79, p. 9). — 

 Analyses of 1 sample each of kelp and mixed seawee<I fron^i the coast of New Hamp- 

 shire are reported. 



The composition of the sew^age of the town of Odessa, T. Seliw.\noff, Chonia, 

 MoTSCHAU, and Boudarew (LoikJu: Ver.<<. Stat., 55 {1901), Xo. 6, pp. 463-474) -—The 

 results reported show great daily, and even hourly, variation in the composition of 

 the sewage, especially in the insi>luble matter. The sewage of this town Avas appar- 

 ently more concentrated than that of other large cities of the world. 



Report on official inspection of commercial fertilizers and agricultural 

 chemicals during the season of 1900, C. A. Goessmann et al. {ifassadmsetts Sta. 

 apt. 1900, pp. 55-63). — This report includes a comparison of the quality of the fertili- 

 zers examined during 1899 and 1900; the trade values of the fertilizing ingredients 

 in fertilizing materials during the same years, with an explanation of the use of these 

 data in calculating the approximate value of a fertilizer; a table showing the average 

 composition of fertilizers examined during 1900; and a list of brands of fertilizers 

 licensed by manufacturers and dealers under the provisions of the State law during 

 the year. P^xcept in case of fertilizers containing only 2 essential constituents the 

 goods examined during 1900 were decidedly superior to those inspected during the 

 previous year. 



Report on general work in the chemical laboratory, C. A. Goessmaxx {Mas- 

 sachusetts Sta. Rpt. 1900, pp. 64-70). — This includes a list of miscellaneous materials 

 sent to the station and examined during the year; notes on wood ashes, comparing 

 the quality of samples examined during 1899 and 1900; a brief discussion of the 

 agricultural value of sewage sludge, with analyses of 8 samples of the material; and 

 notes on phosphatic slag as a source of phosphoric acid for manurial purposes, 

 accompanied by analyses of 9 sam}>les of slag examined at the station. 



Analyses of commercial fertilizers, ]\I. B. Hardix {SoiitJi Carolina Sta. Bui. 

 GO, pp. ^4)- — This bulletin contains the analyses of 186 samples of fei'tilizers ••ollected 

 during the season of 1900-1901, with a discussion of the composition and valuation 

 of fertilizers and the laws and regulations governing the sale of commercial fertili- 

 zers in South Carolina. 



The world's production of phosphates, Maizieres {L'Engrais, 16 {1901), 

 No. 28, pp. 662-664). 



FIELD CROPS. 



Report of the agriculturist, "W. P. Brooks and H. M. Thomson {MassacMisetts 

 Sl'i. Rpt. 1900, pp. 91-123). — The experiments here reported include fertilizer, soil, and 

 variety tests with different field and garden crops, and are in continuation of work 

 previously reported (E. S. R., 12, p. 226).
