AFTEKNOON SESSION. 



Wednesday, Febriiarj 21, 1012, 1.45 P. M. 



THE CHAIKMAN: The meeting will please be in order. 

 We are to have first this afternoon, a paper by Dr. A. D. Hopkins, 

 who is in charge of forest insect investigations. Bureau of Ento- 

 mology, U. S. Department of Agriculture. 



DE. HOPKINS: Mr. Chairman: I regret exceedingly that 

 the insects are interfering in this trouble, and making more of 

 it. Heaven knows tliey are making enough trouble of their own 

 all over the country. Tlmy are killing the merchantable sized 

 pine in the Rocky Mountains and on the Pacific Coast at a 

 greater rate than that by fire alone. They are killing the pine 

 in the South. They are killing the hickory, they are killing tl; .' 

 oak and the hemlock, and now they are interfering in this dis- 

 ease. They are also killing chestnut on their own account. 



Mr. Chairman, 1 have two papers here, both about the same 

 thing. One is an abstract which will take about ten minutes; 

 the other is the whole paper, which will take about half an hour. 

 I presume you would like to have the abstract, which Avill take 

 less time. 



THE CHAIRMAN: I presume it would be better to give us 

 the abstract, and then, if there is more time available, let it 

 be spent in general discussion. AVill that meet with your ap- 

 proval? 



DR. HOPKINS: Yes; that is what I intended to do. 



Dr. Hopkins read the following paper: 



While the historj^ of the discovery of the chestnut blight dis- 

 ease and its spread from a local to an interstate problem is well 

 known and much interest is manifested in the subject, the history 

 of extensive dying of chestnut from various otlua- causes is not 

 so well known. 



When we review tlie history of extensive dying of chestnut 

 during the past half century in Mississippi, Tennessee, Georgia, 

 South Carolina, North Carolina and Virginia, it is surprising
