THE CHAIIIMAN: On accouut of llie pai'ticiikiily interest- 

 ing address that we beard from Professor Davis to-niglit, tlie 

 Cliair tlionght that there would be some questions directed to 

 bim, but it seems tbat tbe discussion bas gone abjng on somewbat 

 different lines. Tbere is one (|uestion however, which Professor 

 Davis has not ansAvered, with reference to gathering the crop 

 while it is still green, if I remember the ([uestion. ^^"ill Pro- 

 fessor Davis kindly answer tbat question? 



PROFESSOlt DAVIS: In September, when tlie burrs are 

 green, you can shake tliem from the trees as you can ii[)p]es, 

 and the entires croj) has been harvested without frost. \Viien 

 th(^y are shaken off, they are allowed to dry a little whib;. ^V^len 

 you shake them oil" in September thay color up brown and the 

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



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

 "Will you please ask Dr. Spalding, of tbe United States Bureau , 

 of Plant Industr}^, what has been done in the vicinity of Wash- 

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

 ease?'' Of course, it will be impossible now to go into tbat 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, 

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

 ciated. 



1)11. SPAULDING : I am not very familiar with the work tbat 

 bas been done in the vicinity, becaut^ie I have been working ou 

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

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

 had been practiced wherever diseased trees have been found and, 

 as far as I- know, that has been fairl}^ successful. There are cases 

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

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

 I)recautions were taken to remove the diseased chips, or even to 

 remove tbe bark from tbe stump, so tbat 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 bad best do one of two things: either take a recess 

 until to-morrow morning at shar]) nine o'clock, or decide Jo si>eiid
