Defiance. Spring wheats : Haynes Blue Stem, Saskatche- 

 wan Fife. 



"The following varieties seem to be resistant, but have not 

 yet been well established as such : Theiss, Oregon Club, 

 Senora, Diehl Mediterranean, Fulcaster, Arnolds Hybrid, 

 California Spring. 



"Some of the hardy prolific sorts not yet well known in this 

 country, but likely to be more or less rust-resistant after 

 thorough acchmation and selection, are — Winter wheats : 

 Prolifero, Banatka, Red Winter, Nashi, Tangarotto, Bearded 

 Winter, Winter Ghirka, Budapest, Crimean, Yx, Bellevue, 

 Talavera. Spring wheats: Alsace, Spring Ghirka. 



" Two varieties which are quite susceptible to rust, but 

 which usually ripen early enough to escape the worst effects 

 of it, are : Early May and Zimmerman. 



" Some others not quite so well known, but probably 

 worthy of trial as rust-escaping sorts, are • — Early Baart, 

 Allora Spring, Kathia, Roseworthy, Japanese No. 2, Yemide, 

 Canning Downs. 



" These last varieties are not likely to withstand very 

 severe winters, and are therefore best adapted to southern 

 districts, where they may perhaps in time become accli- 

 mated. Yemide and Kathia are probably the most hardy 

 of the six. Canning Downs winterkilled in one trial, even 

 in Mississippi." 



Stinking smut {Tilletia foetans (B. & C.) Trek, Tilletia 

 Tritici (Bjerk.) Wint.). — This smut (for practical pur- 

 poses the two may be considered as one) is readily distin- 

 guished from the loose smut by the fact that it attacks only 

 the grain, not the inclosing chaff. The head therefore re- 

 mains of much more nearly normal appearance, and it is
