CEREAL RUSTS OF THE UNITED STATES. 



high breeding and careful selection and some proved to be quite rust 

 resistant, but as most of them were unfixed crossbreds their rust resist- 

 ance could be fairly determined only by several years' trial and careful 

 elimination of the most rust liable and less hardy j)lants. As shown 

 by the table, it was found that almost invariably selections from the 

 sporting i)rogeuy of unfixed crosses of bald and bearded varieties pro- 

 duced in the following years plants which showed that the bearded 

 sorts are much more resistant to rust than the bald. 



In addition to the experiments made by the writer, several were made 

 in cooperation with the Department by i^ersons in different States, the 

 object being to test a few of the same varieties in different localities to 

 determine their rust resistance and adaptability to such regions. Owing 

 to various causes, chiefly lateness of seeding and drought, many of the 

 experiments were entire failures, and in some cases the occurrence of 

 rust Was not carefully recorded. Only four were reported upon, these 

 having been carried, on by Prof. li. 0. Kedzie, at the Michigan Agri- 

 cultural College in 181>G; Mr. B. F. Snyder, at Liberty, Indiana, in 1896; 

 Mr. J. E. Payne, superintendent of the Rainbelt E.xijeriment Station, 

 at Cheyenne Wells, Colorado, in 1897; and by Mr. S. 1. Wilkin, at Bow 

 Creek, Kansas, in 1897. The following table gives a summary of the 

 four reports :

Although this table gives but little information, still it is of some 

 interest in connection with Table 3.
