SOILS — FERTILIZERS. 431 



$2,074,121 in value. The average price per ton in 1907 — $4.70 — was 58 cents 

 greater than in 1900, an increase of 14 per cent." The production from Florida 

 was greater than in any previous year of the history of the phosphate industry. 

 There was also a large increase in the production from South Carolina and 

 Tennessee. 



Potash, in granitic soils, J. del Campo {Prog. Ayr. ij Pecuario, 1'/ (1908), 

 No. Jl'-i, pp. 197-200, figs. 2). — In this article data are presented to show that 

 although granitic soils contain considerable percentages of potash they are 

 often benefited by applications of potash fertilizers, thus indicating that the 

 potash of feldspar, the characteristic potassic constituent of granite, is rendered 

 available in the soil very slowly. 



On the utilization of leucite. C. Manuelli (Ga::. Chim. Itah, 3S (1908), I, 

 No. 2, pp. U3-152; abs. in Chcm. Zcntbl., 1908, I, No. 22, p. i9.^o ) .—Compara- 

 tive tests of various technical pi'ocesses for obtaining potash salts from leucite 

 are reported. Heating a mixture of the leucite with powdered charcoal and 

 alum to a dull red glow for one-half hour and extracting with boiling water and 

 steam gave good results in the author's experiments. 



The industrial treatment of leucite and leucitic materials, G. Gallo (Rend. 

 Soc. Chim. Roitia, 6 (1908), No. 1, pp. 29, 30).— A process of treating the mate- 

 rials for the recovery of the potash in an electric furnace with dry chlorin gas 

 is briefly described. 



The potash industry (Saateii, Diingcr u. Futtermarkt, 1908, No. 2Jf, pp. 

 651-658). — The present status of this industry is reviewed. 



[Fertilizers in connection with the beet-sugar industry] (Sugar Beet, 29 

 (1908), No. 1, pp. 23-26). — Brief notes are given on the utilization of the nitro- 

 gen of distillers" wash, the transformation in the soil of lime nitrogen, filter 

 press scums as fertilizers, the increased yield of beets due to stimulants such 

 as potassium iodid and sodium fluorid, and the fertilizer consumption of mother 

 beets. 



Fertilizer experiments with sulphur water, H. E. Muller and K. Stormeb 

 (Deut. La lid w. Presse, 35 (1908), No. 34, p. 36.9).— This material, which is an 

 ammoniacal liquor obtained as a by-product in the manufacture of paraffin by 

 the destructive distillation of coal, and is very similar in composition and gen- 

 eral character to ordinary gashouse liquor, was used with good results on sandy 

 and sandy loam soils. On cultivated soil it should be applied about 14 days 

 before planting. As a top-dressing it should be applied not earlier than 4 weeks 

 after the plants begin growth. On well-drained meadows it may be applied at 

 frequent intervals to an aggregate amount of 160 gal. per acre annually. 



Fertilizer analyses, A. J. Patten, S. L. Jodidi, and C. B. Collingwood (Michi- 

 gan 8ta. Bui. 252, pp. 3-32). — This is a report in the usual form of the results 

 of the inspection of 275 samples of fertilizers collected during the months of 

 April, May, and June, 1908. 



Analyses of fertilizers — fall season, 1907, B. W. Kilgore (Bui. N. C. Dcpt. 

 Agr., 29 (1908), No. 3, pp. 51). — The analyses here reported are of samples col- 

 lected by the fertilizer inspectors of the State department of agriculture during 

 the fall of 1907. A list is given of brands of fertilizers registered for sale in 

 1908. 



Analyses of fertilizers — spring season, 1908, B. W. Kilgore (BuJ. N. C. 

 Dept. Agr., 29 (1908), No. //, pp. 50). — The analyses here reported are of sam- 

 ples collected by the fertilizer inspectors of the State department of agriculture 

 during the spring of 1908. A list is given of brands of fertilizers registered for 

 sale in 1908. 



Analyses of commercial fertilizers, W. Frear (Penn, Dcpt. Agr. BuJ. 163, 

 pp. 51). — This is a report of inspection of fertilizers in the State from August 1
