were uiuily/ed at ditiViviit times. From Oetoher 19 to NovtMiihtT 1 

 the suiifar ('oiiteiit of the beets averati-cHl 14.74 per cent, thi^ purity 

 82.28, iind from November 4 to 23, 13.89 and 81.03 per cent, respec- 

 tively. It is thought that this decrease in sugar content and purity 

 was more than made up by the increased growth of the Ixn^ts. On 

 muck soil this increase in growth from October 20 to November 23 

 amounted to 2,893 lbs. per acre. The analyses of about 4(50 samples 

 of sugar beets between October 15 and Decem])er 1 showed a similar 

 decrease in sugar content and purity as the season advanced. 



Seven varieties of sugar beets were grown in 1898 and again in 1899. 

 In 1898 Zehringer, Kleinwanzlebener, Vilmorin Improved, Vilmorin 

 Blanche, and Schreiber Elite were the best varieties grown, while in 

 1899 Zehringer, Russian, Rolker EE, and Rolker ZZ gave the most sat- 

 isfactory results. 



The relation of the size of the beet to its sugar content was studied, 

 and some figures are given on the subject. In general the smallest 

 beets were richest in sugar and the largest poorest in this constituent. 



In the cooperative experiments beets were grown on sandy soil, 

 sandy loam, and clay loam, and various fertilizers applied alone and in 

 combinations. Data regarding the yield, sugar content, and purity 

 of beets grown on each plat are tabulated. No particular!}^ significant 

 yields were obtained on any of the plats. The best results followed 

 the application of 480 lbs. per acre of a mixture of 120 lbs. of nitrate 

 of soda, 240 lbs. of phosphatic rock, and 120 lbs. of muriate of 

 potash. Relative to the use of nitrate of soda the author states that 

 when used alone it "generally produced beets of a low percentage of 

 sugar, but when used in connection with sufficient amounts of the 

 other 2 elements normal beets are produced." 



The yields of beets obtained on clay loam, sandy loam, sand, clay, 

 and muck in the cooperative experiments with farmers in 1897 and 

 1898 are summarized. The results indicate that "a mixture of equal 

 parts of sand and clay, or var3"ing 10 per cent from equal parts, is a 

 superior sugar-beet soil." Fairly good results were obtained in these 

 experiments on muck soil, a result which it is thought will prove of 

 considerable economic importance to the State because of the abun- 

 dance of these soils. 



Results secured with sugar beets at other stations are noted and 

 illustrations given of diseased roots and roots grown under unfavor- 

 able cultural and soil conditions. 



Sugar beets in 1898, R. H. McDowell and N. E. Wilson {Nevada 

 Sta. Bid. 1^3^ pp. SO, map l,pls. 5,figf<. 2). — Cultural experiments with 

 sugar beets are reported in continuation of previous work (E. S. R., 

 10, p. 631). As a rule 8 irrigations are given sugar beets in Nevada. 

 Eight varieties were grown in 1898. The sugar content of the juice 

 of 25 samples grown at the station and over the State averaged 17.67
