with sulphate of potash second. Soy beans produced better with barnyard 

 manure, superphosphate, and potassium chlorid, being closely followed by 

 those with potassium chlorid and barnyard manure. Barnyard manure alone 

 apparently gave better results than either chemical alone, or barnyard manure 

 and superi^hosphate.

Annual report upon the agricultural department, W. H. Johnson (Ann. 

 Rpt. Agr. Dept. SoutJi. Nigeria, 1911, pp. 19). — This report gives results of field 

 tests of maize, cassava, cowpeas, guinea corn, ere beans, and cotton, in which

 W. W. Smart (Ann. Rpt. Dept. Agr. Bombay, 1911-12, pp. 78). — In this report 

 are given some results of experiments with rice, cotton, sugar cane, peanuts, 

 clover, and alfalfa, in which an imiwned variety of cotton. Cambodia (102 E), 

 produced better than the local varieties, yielding 410.5 lbs. seed cotton per acre 

 and giving about 38 per cent lint, or 3 per cent more than the local varieties. 



Annual report of the Cuttack Agricultural Station, 1911—12, G. Shkbbard

 tions in the content of protein, fat, ash. sugar, crude fiber, and starch in the 

 kernel were observed which the authors ascribe to segregation. 



Corn culture, W. G. Bearing (Louisville, Ky., 1913, pp. 105).— This book pur- 

 ports to be a conversation between a farmer and his trader friend, In which
