 experiment in wliicli tliliereiit fertili/crs were conipared Avitli ii(» niaiimc 

 on seventeen plats wliere early ]»()tat(K's were ])lant('<l by the trcncli 

 niethod. The highest yield was with ;i eondnnation of aeid phosphate, 

 kainit, and dried blood. 



Grasses and foracje plants (p. 10). — A tabulated record of the condi- 

 tion Decembers, 181)0, of 2() species of gTasses and forage plants sown on 

 thin, sandy soil at the station in the spring of the same year. Japan 

 clover is the only kind reported in good condition. 



Sugar-beet experiments (pp. 11, 12). — A brief tabulated record of the 

 yields of 13 varieties of sugar beets, and of American Imperial sugar 

 beet on sixteen x)lats where different amounts of cotton-seed meal, acid 

 phosphate, and kainit, singly and two by two, were compared with no 

 manure. The highest yield, 13,280 pounds ]>er acre, was with 50 pounds 

 of acid phosi)hate. 



liEroKT OF Chemist, G. L. Teller, B. S. (pp. 1.3-28). — The autlior 

 entered ui)on the duties of his ofiice September 20, 1800, siu'cceding (J. 

 B. (Jollingwood, B. S. The report includes notes and taluilated data on 

 analyses of sorghum, sugar beets, and fertilizers. 



Sorf/hnm analyses. — The work on sorghum during 1800 comprised a 

 conii»lete analysis of 352 samples of juice, besides a partial analysis of 

 225 other samples, made in connection with (1) an experiment to study 

 the effect of fertilizers on the yield of sugar, (2) a test of varieties, and 

 (3) an examination of juice as an index to the selection of seed. 



Effect of fertUizers on yield of sugar. — Kainit, acid ])hosi)hate, and 

 cotton-seed meal in different amounts and combinations were comi)ared 

 with no manure on 40 fiftieth-acre plats planted with Early Orange 

 sorghum. The highest i)er (;ent of vsucrose was obtained when the three 

 fertilizers were combined, and in general the application of kainit seems 

 to have had "a beneficial influence upon the amount of sugar in the 

 canes and juice." This is in agreement with the results of a similar 

 exi>eriment reported in the Annual Report of the station for 1880 (see 

 Experiment Station Record, v(J. ii, p. 317). 



Test of varieties.^ A tal)ulated record of analyses of 18 varieties. 

 "In nearly every case tlie degree Brix of the juices analyzed here is 

 lower than in that of the cane from which the seed was selected. All 

 of the varieties polarized on an average more than 14 per cent of sugar. 

 Of the 6 varieties the juices of which showed more than 15 per cent of 

 sugar, all but one (Link Hybrid) were said to be crosses. The same 

 varieties show: a relatively high i)urity coetticient." 



Sugar-beet experiments. — Tabulated analyses are given of sam])les of 

 beets grown in the experiment referred to above. In only one case 

 (AAHiite Imperial 11.8 per cent) was the per cent of sucrose in the juice 

 above 9 jier cent. 



Fertilizer analyses. — Analyses of 6 samples of commercial fertilizers.
