1920] SOILS — FERTILIZERS. 631 



was in Florida, where the average price per ton rose from $5.74 in 1917 to 

 ^V.).')S in 191S. Die average price per ton in Wyoming was $18.75, tlie highest 

 price in any Stale. 



Twelve per cent of tlio total quantity of lime sold in 1918 was used for 

 agriculture. This amounted to :?01,047 tons, valued at $2,698,848, a decrease 

 of 20 per cent in quantity cnniitared with the output of 1917, but an increase 

 of 9 per cent In value. Ajrricultural lime was produced in 27 States and in 

 Porto Kico in 1918. Pennsylvania led with a production of 200,073 tons, about 

 25 per cent of the total output of the State. The other leading States in 

 order of production were Maryland, Ohio, Virginia, and West Virginia. New 

 Jersey's very small production was all used for agricultural purposes, and 

 of Maryland's production 64 per cent was used in agriculture. The average 

 price per ton of lime used in agriculture ($G.90) increased $1.83 over the 

 price for 1917. AgricuUunil lime included 3,304 tons of lime, valued at 

 $.30,328, reiK)rted as sold for use in prepared fertilizer, and 1.989 tons, valued 

 at $0,750, sold combined with wood ashes. 



Of the total marl produced, 57,821 short tons, valued at $148,873, or $2.57 

 per ton, was fresh-water marl, consisting mainly of small shells of fresh-water 

 animals. 



The value of late glacial drift from the Province of Bolius as liming 

 material for peat soils poor in lime, H. voN Feilitzen and E. Nystkom 

 iSvennka Mosskulturfor. Tidskr., 34 (1920), No. 2, pp. 115-124, figs. 5).— Ex- 

 periments on peat soils poor in lime growing red clover to compare coj^rse 

 and finely ground glacial drift with ground limestone as sources of lime are 

 reiwrted. These materials were added in amounts efiui\alent to 1,000, 2,000, 

 and 4,000 kg. of calcium oxid per hectare (890, 1,780, and 3,5G0 lbs. per acre). 



The finely ground glacial drift gave results comparable to those given by the 

 ground limestone, and in some cases gave* better results. The finely ground 

 drift gave much better results than the coarse drift, and in the smallest 

 applications was better than the largest applications of the coarse material. 

 Comparisons of the solubilities of the glacial drift and of ground limestone 

 in water saturated with carbon di<)xid made by H. Christensen showed that 

 the coarse drift material was slowly soluble as compared to the fine drift, and 

 that the fine drift was in all cases equal in solubility to the ground limestone. 



It is concluded that this glacial drift is equal to high-grade limestone as a 

 carrier of lime, but that it must be finely ground. 



Analyses of fertilizer by the department of agriculture for 1919 (To. 

 Dept. Agr. and Immigr. Bui. 149 (1920), pp. S-11). — Analyses of 60 samples of 

 fertilizers and fertilizer materials, collected for inspection in Virginia during 

 the fall of 1919 and found to be deficient in one or more constituents, are 

 reported. 



[Fertilizer inspection work for the spring of 1920] (Va. Dept. Agr. and 

 Immigr. Jiul. 153 (1920), pp. 14-27). — Actual and guarantied analyses of 71 

 samples of fertilizers and fertilizer materials offered for sale in Virginia during 

 the spring of 1920 are reportetl, all of which were deficient in some respect. 

 In addition, a list is given of 235 samples of fei'tilizers which met the 

 gmiranty. Analyses of 7 samples of burnt lime, 13 samples of unburnt lime, 

 and 3 .samples of lime and potash are also reported. 



Tfie fertilizer control law and how to comply with it, E. G. Proulx (7h- 

 diana Stu. Circ. 96 (1920), pp. 8, fig. 1). — The purpose of this circular is to 

 furni.sh information concerning the law regulating the sale and inspection of 

 commercial fertilizers in Indiana, as pas.sed by the legislature in 1881 and 

 amended in 1889 and 1901. The full text of the law is given, together with a 

 description of the method of administering it.
