The average data show that the Hard Federation exceeds Early 
Baart, Pacific Bluestem, Marquis, and Kharkof in practically all of 
the important milling and baking factors. In weight per bushel it 
is exceeded by Kharkof, in crude protein of the wheat by Pacific 
Bluestem, and in volume of loaf by Marquis. In all other compari- 
sons Hard Federation ranks highest. The two years' data therefore 
indicate that Hard Federation is a better milling and bread-making 
wheat than Early Baart, Pacific Bluestem, or White Australian, 
is better than Kharkof when grown in these two sections of the 
Pacific coast area, and better than Marquis when grown in California. 
The results obtained by the grain company and the flour company 
referred to from samples of wheat grown in 1919, at Moro, Oreg., 
and Chico, Calif., respectively, are in close agreement with our own 
experiments. 
AUSTRALIAN WHEATS SUSCEPTIBLE TO DISEASE. 
Experiments have shown that Federation, Hard Federation, and 
White Federation, as well as most other Australian varieties of wheat, 
are susceptible to black stem rust (Puccinia graminis) , to the yellow 
stripe rust (Puccinia glumarum), and to the leaf rust {Puccinia 
triticina). They are also susceptible to bunt or stinking smut 
{Tilletia foetens and Tilletia tritici). In Australia they are also very 
susceptible to flag smut (Urocystis tritici) and to take-all (OpMo- 
bolus graminis). 
In the drier portions of the Pacific coast area black stem rust 
rarely occurs and, therefore, is not a factor in wheat production, as 
it is east of the Rocky Mountains. The yellow stripe rust, however, 
frequently occurs, but heavy infections have been noted without par- 
ticular reduction of yields. There has never been a serious epidemic 
of stripe rust in the United States, although it is frequently very 
destructive in Europe. Some leaf rust generally occurs in the 
Pacific coast area, but it also is not destructive.
