rUOFF.SSUK DAVIS: in Seplemher, when lli<- hnrrs are 

 green, you can shake (hem from (he (i-<'es as you can ajjples, 

 and the en(ire ci-o|i has been hai-vesled without frost. When 

 they are shaken oil", I hey are allowed (o {\i-\ a lillle while. When 

 you shake them oil' iu September they cohtr n|i brown and the 

 frost, I think, has nothini;' to do with it. 



THE CIIAIK.AIAN: This note has been sent to the Chair: 

 ''>Viil yon jdease ask Dr. Spalding, of the United States lUireau 

 of l*lant Industr}', what has 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 impossibhi now to go into (hat sub- 

 jec( at length, bu( if Dr. Spaulding will tell us, in a miniUe or 

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

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

 ciated. 



DK. SPAULD1N(J : 1 am no( very familiar wilh (lie work (hat 

 has been done in (he vicini(y, because 1 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 

 ha<l been i)racticed wherever diseased trees have been found and, 

 as far as 1 knoAv, 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 were taken to remove the diseased chips, or even to 

 remove the bark from the stumj), s() (hat certain cases might very 

 well be expec(ed (o have (he fniigus at this time. 



THE CirAIPtAlAX: l( seems m.w, (he (ime being half past 

 ten, (hat we ha<l bes( do <uie of (wo (liings: eidier (ake a recess 

 un(il (o-morrow morning at slmrj) nin<' o'clock, or decide to s])end
