February, '22] presidential address: discussion 59 



ical agencies. The collaboration of our investigators during the past 

 year with the plant pathologists and agronomists in the "take-all" 

 disease investigations in relation to Hessian fly injury, is a case in point. 

 Referring to the "greenbug" situation, mentioned by Professor Dean, 

 it is true that honest differences of opinion exist as to the true origin of 

 the great outbreaks; but such differences do not necessarily constitute 

 obstacles to progress, indeed they are often the very life of scientific 

 research. The Bureau recently has taken steps (by placing an observer 

 in northern Texas) to settle this matter, once for all, if this should 

 prove to be humanly possible. 



I congratulate Professor Dean upon his extremely able and interesting 

 presentation of this most important subject. 



Mr. E. p. Felt: It seems to me that Professor Dean in his discussion 

 has struck a keynote which we can all take to heart. That is, a better 

 and closer cooperation, and even in cases where there is an honest 

 difference of opinion, sometimes by consultation, at least a form of 

 statement can be agreed upon which will not result in presenting appar- 

 ently diametrically opposite views. I feel the liberty of disagreeing 

 with my associates at times, and I expect they are going to disagree 

 with me, but I like, if possible, to keep that out of public print. We 

 ought to present, so far as possible, a united front in urging remedial or 

 control work along any line whatsoever. 



There is one thing I would like to mention in connection with Pro- 

 fessor Dean's address, and it is also cooperation. I refer to the coopera- 

 tion that the men in the States should render the Insect Pest Survey 

 work begun last year. That was started, as you gentlemen may re- 

 member, partly at least through action taken by this association. There 

 has been some excellent cooperation. There is an opportunity for a 

 great deal more, and it seems to me that this venture — ^we can hardly 

 call it less than that — is in the experimental stage. It is sonething 

 which should demonstrate its utility. To my mind it has considerable, 

 if not great possibilities. We ought not to be content until those 

 possibilities have been developed to every reasonable degree. We do 

 not think it is going to solve all questions; it cannot. But we ought 

 to have eventually an Insect Pest Survey which will picture accurately 

 and promptly entomological conditions throughout the entire country, 

 so that those cooperating both in Washington and throughout the 

 country would have a better and fuller knowledge of what is going on 

 in insect life, and therefore be in a position to render better service to 

 their clientage. 



Mr. S. J. Hunter: I want to express my hearty appreciation of the 

 matter presented this morning by Professor Dean, but more especially 

 to testify that he not only preaches, but he practices what he preaches.
