The possibilities of sugar beet culture in Washington, I. D. Cardiff ( Wash- 

 ington Sta. Popular Bui. 105 (1916), pp. 3-8).— This bulletin is a brief discus- 

 sion of the sugar beet in Washing:ton, based on studies previously reported 

 (E. S. R., 6, p. 543 ; 7, p. 762 ; 9, p. 240 ; 10, p. 545). Experiments in the Yakima 

 Valley are cited showing that beets can be produced in Washington which test 

 from 15.5 to 17.6 per cent of sugar in the juice and 16.7 per cent in the beet, 

 with an average purity of 85.2 per cent. The value of the sugar beet as a soil 

 cleansing crop is pointed out, together with its adaptability to alkali condi- 

 tions. 



Experiments with Marquis wheat, C. R. Ball and J. A. Olaek {U. S. Dept. 

 Agr. Bui. 40O {1916), pp. 40, figs. iO).— This bulletin gives a brief history and 

 description of Marquis wheat, and reports the results of experiments in 13 

 different States, representing a wide range in soil and climatic conditions, and 

 grouped as follows: (1) The northern Prairie States, or subhumid section; 

 (2) the northern Great Plains States, or semiarid section; (3) the Basin and 

 Coast, or arid areas; and (4) the irrigated districts of the northern Rocky 

 Mountain region and Great Basin areas. The experiments in each section are 

 discussed in detail and the comparative yields tabulated and discussed. 



In the northern Prairie States the facts were brought out that where hard 

 red winter wheats of the Crimean group can be grown they outyield any spring 

 wheat varieties, but that Marquis wheat outyields all other spring wheat varie- 

 ties in that section. The results in the northern Great Plains area show that 

 where winter wheat can be grown it outyields any spring wheat. Among the 

 spring wheats tested the durums outyielded all other groups, although Marquis 

 was superior to all the common .spring wheats. In the Basin and Coast areas 

 Marquis wheat did not prove a high yielder, and can not be recommended for 

 any district west of the Rocky Mountains. Under irrigation Marquis has not 

 proved to be a good yielder except in limited experiments east of the Rockies. 

 It is reported as being a first-class milling wheat.
