418-430. 1919. — The 43rd report of the fertilizer experiments with the continuous growth of 

 wheat and barley is made. The application of ammonium sulphate year after year has pro- 

 duced an acid condition which prevents a good growth. Largest yield was secured with 

 stable manure. Manure from animals fed linseed and cotton cake was practically the same as 

 that from corn fed animals. Leather as a source of nitrogen was ineffective. Ground lime- 

 stone produced larger yields than did chalk. — J. J. Skinner.

 tural Society of England. Pot-culture experiments, 1919. Jour. Royal Agric. Soc. England, 

 80: 430-438. 3 pi. 1919. — It is shown that insoluble forms of arsenic, as arsenious acid, up 

 to 0.1 per cent can be used without injury to wheat. The more soluble forms as arsenic acid 

 or the soda salts of either arsenious or arsenic acid cause a decrease when used in amounts 

 of 0.02 per cent and kill at 0.05 per cent. As a top dressing sodium nitrate proved more valu- 

 able than did ammonium sulphate, ammonium nitrate or calcium nitrate. — J. J. Skinner.

1385. Anonymous. Potash and bromine in Texas lakes. Amer. Fertilizer 52 8 : 72-73. 

 1920. — Brines that contain potash and bromine have been discovered in alkali lakes in Gaines, 

 Lynn and Tern r Counties, Texas, on the plain south of the Panhandle region. The lakes range 

 in area from 35 to 7000 acres, lie in flat valleys and have no surface outlet. Analysis of brines 

 from two of the lakes is given. The salts of these brines contain a smaller percentage of pot- 

 ash than that yielded by the potash material of Germany, Alsace, Nebraska, and Searles Lake, 

 but they contain a relatively high percentage of bromine. — J. J. Skinner.

 Garelli reported in La Nature for Nov. 29, 1919, on extracting nitrate of ammonia from surplus 

 stock of explosives. — O. A. Stevens.

 in mixed fertilizers in 1918. — J. J. Skinner.

 instrument is a double disc made of card board and is unique in many particulars. With a 

 given crop in mind the disc is turned, one upon the other, according to directions and a desir- 

 able fertilizer combination is given for any soil type. — /. /. Skinner.
