 sample was sent to Kansas and one to California 'for the 1907 seeding. 

 Likewise the 1906 Kansas crop was planted again in Kansas and was 

 silso sent to South Dakota and California for 1907 .seeding. The 

 same course" was followed with the California seed. For the 1908 

 crop, the seed used was that wilich had been obtained from the con- 

 tinuously grown plot at each station. In exactly the same way a 

 -ample of Crimean w^as grown in Texas, Kansas, and California, the 

 original seed having been grown in Kansas in 1905. Samples of each 

 crop were collected and analyzed for water, ash, phosphoric acid, total 

 nitrogen, alcohol-soluble nitrogen, salt-soluble nitrogen, fat, fiber, 

 pentosans, invert sugar, and cane sugar. In addition to this, the 

 weights per bushel and per 1,000 grains were taken and the character, 

 including the flinty or starchy condition of the grain, observed. The 

 results obtained on the Crimean and Kubanka wheat during the 

 successive years are given in the following table:
