it will dry and be consumed in the next fire. . . . While the amount of 

 potash in the wastes themselves is relatively very small, the percentage of 

 potash in their aslie.s is in some cases surprisingly large." 



Recent analyses at the station show the following percentages of potash and 

 phosphoric acid in the ashes of certain common vegetable wastes : 



Potash and phosphoric acid in the crude ashes of common vegetaile tcastes. 



The fertilizing value of some household wastes, P. E. Beowninq (Jour. 

 Indus, and Eng. Chem., 9 (1911), No. 11, p. 10-^3; abs. in Internat. Inst. Agr. 

 [Rome], Internat. Rev. Sci. and Pract. Agr., 9 (1918), No. 1, p. .^2). — Ash 

 analyses, made in cooperation with J. P. Street of the Connecticut State Experi- 

 ment Station, are reported. These include those noted in the preceding ab- 

 stract, except the analysis of red banana stalks and corncobs, as well as the 

 following additional analyses : 



Potash and phosphoric acid in the crude ashes of some household loastes. 



Nitrogen determinations are reported in the case of the dried coffee grounds 

 (1.99 per cent), and lime determinations in the case of the lamb chop bone (32.2 

 per cent) and egg shells (52.12 per cent). 



Inspection of commercial fertilizers, H. D. Haskins, L. S. Walkek, W. A. 

 AxLEN, and R. S. Scuix (Massachusetts Sta. Control Ser. Bui. 8 (1911), pp. 

 6Jt). — This reports the results of actual and guarantied analyses of 626 official 

 samples of commercial fertilizers and fertilizer materials, representing 418 

 distinct brands offered for sale in the State and inspected during 1917. The 

 chemical character of the raw materials, mixed fertilizers, and acid phosphates 

 is discussed, and the quality of the nitrogen, phosphoric acid, and potash 

 contained in the fertilizer mixtures indicated. 



Tertilizing materials, F. T. Shutt (Canada Expt. Farms Rpts. 1916, pp. 

 125-139). — This reports analyses of limestones and marls from various parts 

 of Canada and of miscellaneous materials, Including fertilime, limekiln refuse, 

 calcareous deposits from rivers and lakes, tanbark ashes, stone meal, pond
