The valuation of ground fish (Ah-s. in tSaatcii, Diinycr ii. Fuftcninnkt, 1007. 

 No. l-'i, pp. J/OS, -f/O'i). — The food aud fertilizer value of this material, as based 

 upon its content of fat, protein, and ash, is discussed. 



Utilization of refuse liquid from beet sirup, L. Klein (Pure Products, 3 

 (1907), Xo. 6, pp. 268-271, fif). 1). — The process of drying this material and using 

 it as fuel, with subsequent utilization as a fertilizer of the ashes obtained, are 

 briefly described. 



Analyses are reported which show that the original liquid contains about 2.8 

 per cent of ash, 0.3 per cent of nitrogen, l.-t per cent of potash, and 0.03 per cent 

 of phosphoric acid. The ash obtained from the material is reported to contain 

 potassium carbonate about 42 per cent, sodium carbonate 12 per cent, potas- 

 sium chlorid 12 per cent, potassium sulphate 8 per cent, potassium sulphite 2.8 

 per cent, and potassium phosphate 0.60 per cent. On storage the ashes decom- 

 pose more thoroughly and the sulphite passes into other forms. 



Report of the chemist — division of fertilizers and fertilizing materials, 

 C. A. GoESSMANN (Massachusetts Sta. Rpt. 1906, pp. 6.5-iS'i). — This includes 

 reports on official inspection of commercial fertilizers and on general work in 

 the chemical laboratory. 



The results of examinations of 533 samples representing 354 brands are sum- 

 marized. Tables show the average composition of the different classes of all 

 fertilizer analyses, and the maximum, minimum, and average composition of 

 special crop fertilizers. A schedule of trade values of fertilizing constituents 

 and a list of licensed manufacturers and dealers are giveii. 



Brief notes are also given on the examination of wood ashes and lime ashes. 



Analyses of fertilizers, spring season 1907, B. W. Kilgore (Bui. X. C. Bd. 

 Agr.. 28 (1907). \o. -). pp. -i-T). — The results of the sjtring inspection and regis- 

 tration of fertilizers in North Carolina are reported, with brief explanatory 

 notes. 



Fertilizer analyses; fall season, 1906, and spring season, 1907, B. W. 

 KiLGORE (Bul. X. C. BO. Agr., 28 (1907), Xo. 7, pp. 77?).— The. names and guar- 

 anteed composition of fertilizers registered for 1907, and analyses and valua- 

 tions of about 700 samples of commercial fertilizers and 105 samples of cotton- 

 seed meal, examined during the fall of 190G and spring of 1907, are reported, 

 with oxi)lanations regarding terms used in fertilizer analyses, freight rates, 

 valuation, etc. 



Analyses of commercial fertilizers, M, B, Hakdin et al. (South Varolina 

 Sta. Bitl. 126, pp. J/O). — This bulletin reiwrts results of analyses of 744 samples 

 of commercial fertilizers inspected under the State law during the season of 

 190G-7. The analyses are accompanied by notes on valuation, the composition 

 of fertilizers and of the materials from which they are made, and the regula- 

 tions controlling fertilizer inspection in the State. 



The legal regulation of the fertilizer trade in Austria (0.s-^r;v. Forst u. 

 Jagd Ztg., 2'> (1907). No. 5, pp. 33, 3J,). — The laws and regulations controlling 

 this industry in Austria are briefly summarized. 



AGRICULTURAL BOTANY. 



Injury to vegetation and animal life by smelter fumes, J. K. Haywood 

 (Jour. Amer. Chem. Soc, 29 (1907), No. 7, pp. 998-1009).— The author gives a 

 summary of results of investigations carried on to determine the injury to vege- 

 tation by sulphur dioxid fumes near Redding, Cal., and around Ducktown, 

 Tenn., and investigations to determine the injury to vegetation and animals by 

 smelter wastes" in the vicinity of Anaconda, Mont. 



The investigations at Bedding have already been noted (E. S. K., 10, p. 953).
