stocks, and the same cards fur the j^early records and the summaries 

 are used as described above (see fig. 14). 



At the end of the fourth 5"ear, when three annual centgener trials are 

 averaged, all but the best stocks are eliminated. The seeds of those 

 which have distinguished themselves are increased during the fifth 

 year, and they are x^lanted in uniform field-test plots in the sixth, 

 seventh, and eighth years. The yields per acre, the grades, etc., are 

 now averaged, and those which here distinguish themselves for yield, 

 grade, etc., are given duplicated milling, baking (Pis. I and V), and 

 chemical tests to thoroughly determine their real value to the miller 

 and to the consumer as well as to the farmer. Some which prove sec- 

 ond best, as well as those which prove worthy of immediate dissemina- 

 tion to the farmers, are sent to the substations within the State and to 

 experiment stations in adjoining States in j)ayment for similar favors 

 from them, since it has been found that a wheat which is best in one

locality is often not best in another locality. Once a new wheat has 

 won its place as having yielded more value per acre at any expei-iment 

 farm than the commonly grown varieties, its quantity is rapidlj" 

 increased, and it is distributed to the farmers of the State or district, 

 at current i)rices for seed wheat. Eacli farmer who receives this 

 wlieat is given a certificate of its genuineness as being the stock 

 which made certain yields in comparison with the other wlieats on 

 trial at the experiincmt station. Tlie farmer is re<iuested to make 

 reports of the yield and other qualities as compared with tlie wheat 

 he is commonly growing on his farm, and lie is expected to sell his first 

 (n'ops at I'ciiuuvei-ative pi'ices to his neighl)ors for seed. In this way 

 the final and most crucial test is given to a new sti'ain or variety of 

 wheat in each county in the State. The amount sent to each farmer 

 is limited to a few bushels, and an effort is made to distribute each 

 new kind to several farmei's in each county in wliicli it is likely to do
