in Death Valley and Silver Peak. It is a matter of some doubt whether these 

 brines can be worked. The investigation of the Carson Sink, Raili'oad Valley, 

 and Columbus Marsh is inconclusive." 



A plea for the increased use of lime, J. Hendrick (Trans. Highland, and 

 Agr. 8oc. 8cot., 5. ser., 26 {1914), pp. 218-232). — This article discusses the ex- 

 tent to which liming is practiced at the present time in Scotland, as compared 

 with its use in former times. It is shown that there has been a marked decline 

 in the use of lime, and the reasons why lime should be more freely used are 

 briefly stated. 



It is estimated that the average loss per acre per annum in the drainage 

 water throughout England and Wales is not less than 500 lbs. of calcium car- 

 bonate, the loss probably being much higher than this on manured soils. Ref- 

 erence is made to the fact that large quantities of carbonate of lime of excel- 

 lent quality for agricultural purposes are annually produced in Scotland as a 

 TDy-product from the causticizing plant of paper works, as previously noted (E. 

 S. E., 30, p. 127). 



Comparative field tests of this by-product and ordinary lime shells and gas 

 lime are reported. The results show that the yields of turnips were largely 

 increased by the use of each form of lime, the waste product being especially 

 effective in this respect. It also apparently reduced the amount of finger-and- 

 toe disease. 



Agricultural lime analyses (Md. Agr. Col. Quart. No. 64 (1914), PP- 8). — 

 Chemical analyses of samples of agricultural lime examined from June, 1913, 

 to May, 1914, inclusive, are reported with brief notes on the use of lime. 

 Mechanical analyses are also given of ground limestones and ground oyster 

 shells. 



Sulphur fertilizer for alfalfa, F. C. Reimer {Pacific Rural Press, 87 (1914), 

 No. 26, p. 717). — Experiments in which flowers of sulphur, iron sulphate, super- 

 phosphate, and ground rock phosphate were applied to alfalfa at the rate of 300 

 lbs. per acre are reported. Largely increased yields where sulphur and sulphur 

 compounds wei'e used are reported. 



The world's production and consumption of chemical fertilizers (Produc- 

 tion et Consommation des Engrais Chimiques dans le Monde. Rome: Inst. 

 Internat. Agr., 1914, 2. ed., pp. XI +162, pis. 2).— The first edition of this report 

 lias already been noted (E. S. R., 30, p. 223). This edition brings the statistics 

 ^p to the end of 1912. 



It is stated that the world's consumption of different classes of fertilizers for 

 1912 was as follows : Natural phosphates. 6,500,000 metric tons ; superphos- 

 phates, 11,000,000 ; Thomas slag, 3,500,000 ; Peruvian guano, 83,000 ; potash salts, 

 ■4,520,959 (equivalent to pure potash, 904,000); sodium nitrate, 2,530,645; am- 

 monium sulphate, 1,200,000, and synthetic nitrogenous fertilizers, 150,000 metric 

 tons. 



State fertilizer tonnage (Amer. Pert., 40 (1914), No. 13, p. 96).— A table is 

 given which shows the consumption of fertilizers in the United States for the 

 years 1909-1913, inclusive, " compiled from the most reliable statistics that are 

 obtainable." 



The figures for each State and Territory for 1913 are as follows: Alabama, 

 474,730 tons; Alaska, 45; Arizona, 600; Arkansas, 52,000; California. 36,000 

 Colorado, 3,500; Connecticut, 50,000; Delaware, 50,000; Florida, 213,728; Geor 

 gia, 1,120,693; Hawaii, 67,000; Idaho, 2,000; Illinois 90,000; Indiana, 193,899 

 Iowa, 3,500; Kansas, 7,380; Kentucky, 75,000; Louisiana 98,778; Maine, 160,000 

 Maryland, 169,000; Massachusetts, 125,000; Michigan, 57,985; Minnesota, 3,500 

 Mississippi, 128,050; Missouri, 60,000; Montana, 800; Nebraska, 1,000; Nevada, 

 800; New Hampshire, 25,000; New Jersey, 156,661; New Mexico, 1,000; New
