ohs. ill. Chcm. CenibL, 1901, II, No. 12, p. 7o5).— Figures are given wliicli hIiow the 

 total amount of these materials annually wasted in France, as well as the amounts of 

 fertilizing constituents which they contain, and suggestions regarding the saving and 

 utilization of the various by-products of the wine industry (including the ashes of 

 the prunings and leaves) for fertilizing purposes are made. 



Froduction of soluble potash salts from potassium feldspar ( orthoclase ) , 

 J. G. A. RiioDiN {Jour. Hoc Chem. Ind., 20 {lOOi), No. 6, pp. 439, 440).— T\w author 

 claims that by heating 100 parts of finely powdered feldspar with 53 parts of slaked 

 lime and 40 parts of common salt to a temperature of 900° C. for an hour from 80 to 

 90 per cent (jf the potassium of the feldspar is converted into potassium chlorid. 



rorniation of oceanic salt deposits, particularly of the Stassfurt beds. 

 XXII. Gypsum and anhydrite. II. The soluble anhydrite (CaS04), J. H. 

 van't Hoff, W. Hinrichsen, and F. Weigert {Sitzbcr. Kgl. Prcuss. Akad. Wiss. 

 Berlin, 1901, pp. 570-578; abs. in Jour. Chem. Soc. \_London], SO {1901), No. 466, II, 

 p. 500). — Investigations are reported which indicate that gypsum is transformed into 

 anhydrite at 98° C. 



Commercial fertilizers, H. A. Huston and W. J. Jones {Purdue Unir. Spec. Bui. , 

 July, 1901, pi>. SO). — "This bulletin contains the new fertilizer law of Indiana, the 

 detailed report and summary of inspections made in 1900 under the old law, the 

 analysis of manufacturers' samples made between July, 1900, and March, 1901, under 

 the old law, and the manufacturers' guarantees made since March, 1901, under the 

 new law." 



Analysis of commercial fertilizers sold in Maryland, H. B. McDonnell et 

 AL. {Maryland Agr. Col. Quart., 1901, No. 13, pp. 1-60). — A report of the results of 

 inspection of fertilizers March to June, 1901. 



Complete fertilizer analyses, spring season, 1901, B. W. Kilgore et al. 

 {Bui. North ('arolina State Bd. Ayr., 23 {1901), No. 5, pj>. ,?--?6).— This includes expla- 

 nations of terms and of the valuation of fertilizers, freight rates, a discussion of the 

 composition of fertilizers for special crops, recent changes in the State fertilizer law, 

 and tal)ulated analyses and valuations of 581 samples of fertilizers. 



Analysis of commercial fertilizers {SoutJi Carolina Sta. Bui. 64, pp. 10). — This 

 bulletin is .supplementary to Bulletin 60 of the station (E. S. R., 13, p. 332) and 

 reports the results of analyses and valuations of 149 samples of fertilizing materials 

 examined during the season of 1900-1901. 



Report of chemist, M. B. Hardin {South Carolina. Sta. i?p/. 1900, pp. 9-1,5). — A 

 brief account of the work of the year in the chemical department of the station, 

 including summaries f)f the general analytical work and of the results of fertilizer 

 inspection, the latter of which have been reported in detail in previous bulletins 

 (E. 8. R., 12, p. 626). During the year ended June 30, 1900, 330 samples of fertil- 

 izers were analyzed. Of these 6 were deficient under the State law, their commercial 

 value, based upon analysis, falling 3 per cent or more below the commercial value 

 based upon guarantee. "Besides these there were 56 samples which fell below guar- 

 antee in one or more*constituents, but whose money value was made up of an excess 

 of other constituents." The average composition of the fertilizers examined is given. 



Commercial fertilizers, 1901, J. H. Stewart and B. H. Hite ( Me.vi Virginia 

 Sta. Bui. 76, p]). 181-195). — This bulletin summarizes the provisions of the amended 

 fertilizer law of West Virginia which took effect May 2, 1901, and reports analyses 

 and valuations of 144 samples of fertilizers examined during 1900. Under the 

 amended law manufacturers are not required to furnish certified sami)les of their fer- 

 tilizers to the inspector, but to submit an affidavit stating not only the amount or 

 percentage of nitrogen, potash, phosphoric acid, etc., but also the materials from 

 which these constituents are derived and the form in which they exist in the fertil- 

 izers. The analysis fee required by the old law is replaced by a nominal registration 

 fee of $1 per brand, the necessary revenue for carrying the new law into effect being
