ar edduced points toward the impossibility of human control so far as these or- 
anisms are concerned, and 4 repetition of the errors made in connection with the 
yhinch bug and grasshopper fungoid parasites is extremely undesirable,

‘ Control Measures:- Information included here should all be of 3 positive 
character; that is to say, it is undesirable to include statements regarding mea- 
sures which have been found to be of little or no practical use, 
Summary of Control Measures:- This should consist of a very brief- 
epitome of the subject, arranged preferably by numbered paragraphs. Sometimes, 
however, 4s in the case of the shorter Farmers' Bulletins, the summary of control 
measures may be included in the statement for the back of the title page.
