SOILS FERTILIZERS. 719 



cusses the fertilizing value of tobacco stalks and ash, tanyard refuse, and burnt 

 sheep manure. 



The more important fertilizing constituents in the tobacco ash were potash 

 24.0S per cent, phosphoric acid 5.o3 per cent, lime 22.44 per cent, and magnesia 

 11.16 per cent ; in the unburut tobacco stalks nitrogen 2.5 per cent, i)h<)sphoric 

 acid 1.13 per cent, potash 5.1 per cent, and lime 4.75 per cent. The ashes of 

 sheep manure contained phosphoric acid 0.83 per cent, potash 7.94 per cent, and 

 lime 6.4 per cent. The original manure from which the ashes were obtained 

 contained nitrogen 0.7 per cent, ixjtash 1 per cent, and phosphoric acid 0.5 

 per cent.

 29). — See the article noted above. 



Hummock soil as fertilizer, A. Mayer (Dent. Landw. Prcs-sc, 37 {1910). No. 5, 

 pp. .'i9. 50)'. — The fertilizing value of the soil of mounds in certain parts of 

 Holland, which were formerly occupied by dwellings, or by cattle during floods, 

 is discussed. 



The question of household g-arbag-e, E. Burelle {Attn. Soc. Agr. »SVj. et 

 Indus. LiioH. 1908. pp. 119-139. flys. '/) .—Methods of collection, transportation, 

 and utilization (including use as fertilizer) or destruction of garbage in 

 various European cities are discussed and a short bibliography of the subject 

 is given. 



The whale factory, E. J. Koch {Amcr. Fert., 32 {1910). No. .',. pp. 10. 11, 

 fif/s. (i). — The process of converting whale meat into fertilizer at a factory In 

 Labradoi" Is briefly described. 



Peat fertilizer filler {Jour. Amer. Peat Soc, 2 {1910), No. J,, pp. 1 50-152). — 

 Jt is stated in this article that " Ihe largest industry based on peat in the 

 United States is the manufacure of filler for artificial fertilizers.^" The methods 

 employed in this industry are briefly described. 



The loss of potash in the burning of molasses, H. Pellet {BuL A-^soc. 

 Chim. Sucr. et Di-stiU., 27 {1909), No. 3, pp. 215-217; ffft.s. in Rev. G6n. Chim., 

 13 {1910), No. 1, Repert., p. 32). — ^The author concludes from analyses of de- 

 posits in furnaces used for the burning of molasses that the loss of potash in 

 the process is due not only to volatilization of potassium sulphid, as suggested 

 by Bauer, but also to the volatilization of other potash salts. 



Analyses of fertilizers, B. E. Curry {Neic Hampshire St a. Bill. l.'iG. pp. 157- 

 16-'/). — The results of inspection of 138 samples of fertilizers sold in the State 

 during 1909 are reported, with brief notes on valuation and on the quality of 

 the fertilizers. A large percentage of the samples did not come up to guaranty 

 with respect to available phosphoric acid, but on the whole there was no great 

 deviation from guaranty. 



[The fertilizer market] (0(7, Paint, and Drug Reporter. 77 {1910), No. 8, 

 pt. 2, pp. 60-62). — Reviews are given of the fertilizer market in New York, Chi- 

 cago, Baltimore. Charleston, and Philadelphia. 



It is shown that the demand for fertilizers in the South was greater in 1909 

 than ever before. The price of nitrate declined as a result of the failure of the 

 nitrate combination and of sulphate of ammonia as a result of the removal of 

 the tariff. The price of potash remained practically unchanged. As a result of 

 a large catch of fish the price of fish scrap was lower. The price of phosphoric 

 acid declined during the year while that of blood and tankage was well main- 

 tained. The price of sheep manure in the Chicago market rose rapidly to $9 

 per ton toward the end of the year. The prices in the markets in other cities 

 were to a large extent controlled by those of New York and Chicago.
