The influence of environment upon the composition of the sugar beet, 

 1902, 11. W. Wiley (T. <S'. Dcpl. A(jr., Bureau of Chemiiiry Bui. 7S, pp.50, drjms. 5). — 

 This season the work was discontinued at the Iowa Station, and at the Indiana 

 Station the crop was a complete failure. In addition to the stations reporting results 

 in 1901 (E. S. R., 15, p. .'54) data were furnished in 1902 by the.Colorado and California 

 station.s. In California the work was conducted at the Pomona Substation and on 

 alkali soil at Chino. The results obtained in the humid and the irrigated regions are 

 discussed separately. The average data of the season are given in the following
