S. Dak., St. Paul, Minn., and to some extent at Moccasin, Mont., and 
Williston, N. Dak. (see Table I). In all cases special attention was 
given to the virulence of the disease on the different varieties of barley 
upon which it occurred. The differences noted are indicated in the 
table as follows: “0” is reserved for absence of the disease; “ -f ” 
indicates very meager occurrence, yet definitely observed; a figure in 
the numerical range from 1 to 10 is used to represent the degree of 
infection in any particular plot as compared to that in other plots. 
As standards “ 1 ” is used to represent the condition where infection was 
very slight—that is, no special search being necessary to find the 
disease; it being present in small amounts on a considerable number 
of plants in whatever part of plot noted; “10” is reserved to represent 
a very abundant infection, where every leaf on every plant was very 
severely attacked. The intervening numbers between 1 and 10 are 
used to represent the respective intervening conditions.
