G {lUO.!), X(i. .7, pp. r)S7-f>54). — Till' iiiiiicnil cniistitiicnts at live (liffcivnt stages of 

 growtli of leavt'S of ])otatoeH grown witliout fcrtilizi'rs aii<l with a])plifations of 

 kainit, superphospliate, and a mixture of kainit and .superphosphate are reported in 

 detail. The result.s show that fertilizing with kainit in connection with superphos- 

 phate often caused, in some cases a <lirect and in otlier cases an in<lirect increase of 

 the lime and magnesium content of the leaves. The maximum content of the potash 

 and ])hosi)horic acid was observed about the first of July, and also about the time of 

 blooming. In the case of other ccmstituents the maximum content wa.s always 

 observed at a later period. The ratio of jihosphorii; acid to i)otash was on the aver- 

 age about l:.3-4. The proportion of magnesium oxid to calcium oxid was on the 

 averagt' of 1 :2.()-2.;). This relation vai'icd very sliglilly with different systems of fer- 

 tilizing and periods of growtli. 



Modern rice culture, \V. .T. Boudreau [PhiUppine Bureau A<jr., J'^nrnicrx' Jiuf. S, 

 pp- '/'!, Ji(js. Jil). — This is a popular bulletin discussing methods of rice culture as 

 adai)ted to the Philippine Islands. The subject matter is presented in English and 

 in Spanish. The topics di.scussed are the soil and its preparation, together with the 

 construction of ditches and levees, the planting of rice, the treatment of the crop, its 

 drainage and irrigation, and the methods of harvesting and thrashing. The ajiplica- 

 tion of fertilizers is briefly explained and short notes on varieties of rice are given. 



The influence of soil and climate upon the composition of the sugar beet, 

 1901, H. AV. Wiley {U. S. Dept. Agr., Bureau <>f Cheuiistrij Bui. 74, pp- 42, 

 cJiarts :l). — The experiments here reported have been previously described and the 

 data obtained in 1900 have been given in a former bulletin (E. S. R., 13, p. 736). 

 The results here shown were derived in the same manner as those of the previous 

 year. In addition to these data the analyses of the soils upon w'hich the experi- 

 ments are in progress are given. The average results for the season are summarized 

 in the following table:
