1126 EXPERIMENT STATION RECORD. 



substitute for imports from Germany. He found in the water of tlie Gulf of 

 Porto Farrajo 0.7 gm. of potassium clilorid and in the motlier liquors of salt 

 works of that region 44 gm. of potassium chlorid per liter. The author recom- 

 mends the establishment of such an industry in Sicily, where no monopoly 

 exists. 



Phosphate mining' in Tennessee, H. D. Ruhm (Engiii. and Min. Joui:, 85 

 {1908), No. 3, pp. 153, 154, fld^- 4)- — Progress in the installation of new works 

 and In the mining of phospates during 1907 is reviewed. It is stated that in 

 spite of the fact that prices were high the total production of the Tennessee 

 field was not more than 400,000 tons. As high as $6.75 per ton was obtained 

 for 75 per cent ]»hosphate for domestic use and $S per ton for 78 per cent phos- 

 phate for export during the year. 



Limestones available for fertilizers, F. B. Van Horn {III. Geol. Survey Bui. 

 Jf, pp. 177-183, pg. 1 ) . — Analyses of 10 samples from southern Illinois are re- 

 ported, 7 of which were of sufficient purity probably to warrant their exploita- 

 tion for fertilizing purposes. 



Tomato refuse, R. Harcourt {Ann. Rpf. Ontario Agr. Col. and E.ritf. Farm, 

 33 {1907), pp. 69, 70). — An analysis of the dried refuse from tomato canneries 

 is reported, showing 2.54 per cent of nitrogen, :i:2S per cent of phosphoric acid, 

 and 0.64 per cent of potash. Assuming 75 per cent of moisture for the materi;il 

 as it leaves the factory, the amounts would be, nitrogen 0.64 per cent, phos- 

 phoric acid 0.82 per cent, and potash 0.16 per cent, a composition comi)aring 

 favorably with that of barnyard manure. 



On the composition of different kinds of sug'ar factory clarification refuse, 

 W. Gabel {Zffichr. Vcr. Deut. Zuclccrindus., 1907, No. 622, II, pp. 989-993; aha. 

 in CJieni. Ztg., 31 {1907), No. 96, Rcpcrt. No. 88, p. 5.95 ) .—Methods of analyzing 

 this material ai'e briefly described and iinalyses of 4 different samples are re- 

 l)orted. In these tlie water varied from about 21 to 50 per cent, the iiitrogen 

 from 0.2 to 0.25 per cent, the phosphoric acid from 0.85 to 0.05 per cent, and the 

 potasli from 0.02 to 0.08 ])er cent. It was found that fermentation of the refuse 

 with wash water from the cossettes did not result in any loss of fertilizing 

 material. In fact there seemed to be a slight gain due to the assimilation of 

 the nitrogen of the wash water by micro-organisms and precipitation of the 

 compounds thus formed by lime. 



Ash constituents of [sugar beets and] beet pulp, W. 1'. (4amblk {Ann. Rpt. 

 Ontario Agr. Col. and Expt. Farm, 33 {1907, pp. 81-8-'/). — Analyses are re- 

 ported which show that the dry matter of the crown portion of a representative 

 sample of sugar beets contained 6.02 per cent of ash, the factory portion 5.(58 

 per cent. The factory portion of the beets contained 1.87 per cent of nitrogen 

 in dry matter. The average of 2 analyses of sugar-beet pulp showed 4.28 per 

 cent of ash and 1.62 per cent of nitrogen in dry matter. From these data the 

 conclusion is drawn that there is " little difference between the ash content of 

 the ci'own and the factory portion " of sugar l)eets. and that "the sale of sugar 

 beets without returning the beet pulp is very exhausting on the soil." 



Dried meat, P. Marsais {Rev. Vit., 28 {1907), No. 725, pp. 52'i-526; ahft. in 

 Rev. Sci. [Paris], 5. ser., 9 {1908), No. 1, p. 19). — The value of this material as 

 a fertilizer, especially for vineyards, is discussed, and the " tanking " and com- 

 posting (with lime and earth) of dead animals and other refuse animal matter 

 are briefly described. The high value of meat fertilizers, especially as carriers 

 of readily available organic nitrogen, is recognized and their more extended 

 use in France is predicted and recommended. 



The utilization of abattoir by-products at Isling'ton {Meat Trades' Jour., 

 27 {1908), No. 1028, p. '19, fiO- !)■ — The ])rocess of tanking condemned meat 

 employed at this place is briefly described.
