there were about twice as many larvae in as near tlie lesions. It 

 would seem that these usually follow rather than precede the in- 

 fection. 



Woodi>ecker AAork Avas noted in a])Out one-i<nitli of the oldest 

 lesions, and not at all in the youngest lesions, — much less fre- 

 quently than beetle work. Ants Avere seldom found actually in 

 the lesions. 



It is expected that careful observations of this same tract next 

 year and later, Avill add much to the value of the present very 

 complete records, Avhich it has been possible to summarize only 

 briefly in this account. 



A good deal is kuoAvn about this parasite; very much remains 

 to be learned. As far as our present knoAvledge goes, the prompt 

 stamping out of advance spots of infection, and tlie general cut- 

 ting off of hopelessly infected tracts, seem to be the only practi- 

 cable means of control. No one perhaps realizes more keenly 

 than the speaker the difiiculties of finding infection and thor- 

 oughly removing it in sparsely settled tracts of large extent and 

 of little value for timber. I have had occasion this last summer 

 to be on the outskirts of the line of spread of this disease through 

 the State, and I have seen numbers of these advance spots. It 

 seems that if Ave can find these spots and remove the timber, Ave 

 Avill be doing much to check the adA'ance of this disease. In this 

 State the fight is on, and it is the part of all good citizens to co- 

 operate in the Avork that is being done. (Applause). 



THE CHAIRMAN : Dr. Caroline Rumbold, Avho is in charge 

 of important research work at the laboratory of the University 

 of Pennsylvania, will present a paper in relation to medicinal 

 remedies for the chestnut tree bark disease.
