8. What is the future of the disease? Will it run its course 

 and disappear? Will it become less virulent? Will resistant 

 varieties appear? Can such varieties be made by selection, hy- 

 bridization, etc.? Can chestnuts be grown with safety beyond 

 the Mississippi river? How long after death of all our trees, 

 may chestnuts be again planted with safety? 



9. Can we expect natural enemies to arise? If it were an 

 insect disease, this might be looked for with more hope. 



10. Can a method of control be discovered by further scien- 

 tific research? Most remedies suggested by unscientific persons 

 are known at once to be valueless and need not be tried. One 

 tiling is certain, the more one knows about a disease, the more 

 liable one is to discover a remedy. If none is possible, the 

 sooner this fact is known, the better for all concerned.

 their attention, and you will get many good points for this Com- 

 mission to act on which you would not get otherwise. 



If you will allow me one minute, I will tell you something 

 which I observed myself. It may be interesting to some of 

 you. I stopped off at a corner of a lane to wait for a car and 

 while I was waiting, I looked on the ground and there saw gypsy 

 moths. I never saw them as large in my life. They were yel- 

 low and blue with big horns, worse than the Massachusetts kind. 

 They were about two inches long and about a quarter of an inch 

 thick. They walked along the track, and I looked at them and 

 followed them. My car came along, and I went down town and
