THE CHAIRMAN : On account of the particularly interest- 

 ing address that we heard from Professor Davis to-night, the 

 Chair thought that there would be some questions directed to 

 him, but it seems that the discussion has gone along on somewhat 

 different lines. There is one question however, which Professor 

 Davis has not answered, with reference to gathering the crop 

 while it is still green, if I remember the question. Will Pro- 

 fessor Davis kindly answer that question? 



PROFESSOR DAVIS: In September, when the burrs are 

 green, you can shake them from the trees as yon can apples, 

 and the entire crop lias been harvested without frost. When 

 they are shaken off, they are allowed to dry a little while. When 

 you shake them off in September they color up brown and the 

 frost, I think, has nothing to do with it. 



THE CHAIRMAN: This note has been sent to the Chair: 

 "\Vill yon please ask Dr. Spalding, of the United States Bureau 

 of Plant Industry, what lias been done in the vicinity of Wash- 

 ington, D. C., to prevent the spread of the chestnut bark dis- 

 ease?" Of course, it will be impossible now to go into that sub- 

 ject at length, but if Dr. Spaulding will tell us, in a minute or 

 two, something of what has been accomplished, and in a word, 

 the main features of the method, I feel sure it will be appre- 

 ciated. 



DR. SPAULDING : I am not very familiar with the work that 

 has been done in the vicinity, because I have been working on 

 other problems most of the time during the last few years. I 

 simply know, in a rough way, that the method of cutting out 

 had been practiced wherever diseased trees have been found and, 

 as far as I know, that has been fairly successful. There are cases 

 where spores have been found on the stump of an old tree. In 

 many cases, I am sure from Dr. Metcalf s statement, no special 

 precautions w T ere taken to remove the diseased chips, or even to 

 remove the bark from the stump, so that certain cases might very 

 well be expected to have the fungus at this time. 



THE CHAIRMAN : It seems now, the time being half past 

 ten, that we had best do one of two things : either take a recess 

 until to-morrow morning at sharp nine o'clock, or decide to spend
