(1*1. IJut such a serions disease of chestnuts has never lu'en 

 known before in any other eonntry. However, insects and weeds 

 and fnngi also, that have been comparatively inconspicnons in 

 their native ct)nntries, when iiiiiddiiced into a new country, 

 sometimes develo]) into serions pests because of their new and 

 nnusually favorable surroundings. 



(3). The Japanese species of chestnut has api)areiitly shown 

 c<Misi(h'rable immunity to the chestnut disease, more so than any 

 other. It may therefore be su])posed that the fnniius is an in- 

 conspicnoits native of Japan, and was brouiiht into this country 

 on seedlings from there. It spread to onr native chestnuts, and

 prevented the spread of the disease in that region, and based (ui 

 this, the much more extensive work in Pennsylvania is now being 

 carried on. and similar work is advocated in other States to 

 prevent its fui-ther spread through the south and west. 



Now, if the ])receding points are true, Pennsylvania has pos- 

 sibly taken a Avise step in trying to control the disease. That it 

 can ever be eradicated, the writer does not believe for one in- 

 stant, and he has serions doubts about the coutrol being effective 

 or financially profitable, since it means a continuous fight, mucli
