c Severity of infection is indicated by numbers, as follows: 1= scattered, usually i or 2 lesions per leal; 

 2= general, averaging 2 to s per square inch of leaf surface; 3=general, averaging 6 to '5 Per square inch ol 

 leaf surface; 4= general, averaging 16 to 50 (estimated) per square inch of leaf surface; and 5= general, aver- 

 aging more than 50 (estimated) per square inch of leaf surface. In cases where the infection on a given 

 plant was not uniform, only the more severely affected leaves were considered (PI. ss)- The negative 

 results of series in which the maximum infection is represented by a number less than 3 are pnnted 

 in bold-face type, and are not included in the summary (Table IX). All other results, unless otherwise 

 noted, are printed in italic type and are included in the summary.
