Luiidir., 37 {190S). pp. 763-17 'i ; alis. in Clicin. Zrnthl., lUOD, /, A'o. .'/, p. 7X5).— 

 Oil rich soils salt iucreasetl both the yield and the sutiar content of the beets 

 and no injurious effect was observed. 



Fertilizing with liquid manure, C. Ortmann (Dcut. Landw. Prcsse, 36 

 (lf)0!)), No. 29, pp. 320-322). — The experience of various investisators with this 

 fertilizing material is summarized. 



Sabak, O. Loucheux {Xaturc [Paris]. 36 (1908), Xo. 1S.',1, Sup., p. 109; abs. 

 in CJirm. Ztg., 33 (1909), No. 35, Repot., p. 167).— Thin material, which consists 

 mainly of refuse from abandoned village sites, is described. A number of 

 analyses are reported which show on the average 1.3 per cent of potash, 3.12 

 per cent of lime, 0.86 per cent of phosphoric acid, and 0.54 per cent of total 

 nitrogen, of which 0.22 per cent is nitric nitrogen and 0.32 per cent organic 

 nitrogen. 



The manurial earth of the Kistna Delta, W. H. Harrison (Agr. Jour. India, 

 Ij (1909), Xo. 1, pp. 56-61). — The material referred to is soil obtained from 

 yards of houses or from sites formerly occupied by houses or cattle sheds. An 

 average sample was found to contain lime 2.G per cent, potash 1.39 per cent, 

 phosphoric acid 0.69 per cent, and nitrogen 0.09 per cent. At the rate at which 

 this material is ordinarily used it supplies about 13 lbs. of nitrogen, 194 lbs. 

 of potash, and 96 lbs. of phosphoric acid per acre annually and as so used is 

 an effective fertilizer, but it is becoming scarce and expensive. 



The valuation of peat litter on the basis of its water capacity, L. Wilk 

 (Ztsclir. MoorkuUur u. Torfverwert., If (1908), pp. 328-3.'i9 ; abs. in Ztschr. 

 Anffcw. CJicm., 22 (1909), Xo. 16, p. 7',0; Chem. Zciitbl., 1909, I, Xo. 11, p. 938; 

 Vlicm. Ztg., 33 (1909), Xo. 37, Rcprrt., p. 173). — This is a plea for reliable meth- 

 ods of determining the absorptive capacity of peat litter for water and thus 

 furnishing a basis for the commercial valuation of such material. 



The fertilizer industry, F. B. Carpenter (Amer. Fert., 30 (1009), Xo. //, 

 pp. 5-9, fig. 1). — This is a brief historical sketch of the development of this 

 industry with some reference to i)resent theories regarding soil fertility. Inci- 

 dentally it is shown that the first legislation in this country providing for the 

 inspection of fertilizers was enacted in ^Massachusetts in 1ST3. 



The use of commercial fertilizers. C. G. Hopkins {Illinois Bta. Circ. 129, 

 pp. 2-'i, fig. 1). — This is an address read before the Illinois State farmers' insti- 

 tute at Rockford in February, 1009, and contains a discussion of this subject, 

 particularly from the standpoint of the grain grower of the Middle West. 



The fertilizer question in China, P. Krische (Erniihr. Pflanzen, 5 (1909), 

 p. 17; abs. in Ztschr. Angrir. (Uirm., 22 (1909). Xo. 15, p. 687). — Commercial 

 fertilizers are to some extent replacing the fecal matter heretofore generally 

 used. 



The wholesale trade in commercial fertilizers (Chen}. Ztschr., 8 (1909), 

 Xo. 8, pp. 86-88). — This is a review of the present status of the fertilizer mar- 

 ket with special reference to German trade. 



[Trade in commercial fertilizers] (llanibiirgs Handel, 1908, pp. 111-117). — 

 Statistics of trade in nitrate of soda, bone meal, bone ash, guano, phosphate, 

 and sulphate of ammonia are summarized. 



The failure of fertilizers used in Gernaany to come up to guaranty, Asmis 

 (///».s-. Landw. Ztg., 29 (1909), Xos. J,, pp. 23, 2.',; 6, pp. 1,3. .'/'/).— The extent of 

 loss from this source by failure of purchasers to insist upon couii)liaiice with 

 guaranty is pointed out. 



Commercial fertilizers, M. A. Scovell, H. E. Curtis, and (J. Kohkkts (Ken- 

 tucky Sta. Bills. 136, pp. 3.'i3-li27; 138, pp. //53-//8«).— Results of examinations 

 of 406 brands of fertilizers registered during 1908 are reported,
