Winter Meeting. 311 



'i 



it was necessary to hold the buds dormant, and said they simply 

 whitened the trees by spraying with a thick chalk solution, which re- 

 mained frozen on all winter and kept the buds dormant all the lime, so 

 that for two winters they had brought them through safe when uncov- 

 ered trees failed. He said Prof. Muller of the University suggested 

 the work to them and that it not only held the buds dormant on warm 

 days but that it prevented leaf curl, which is a universal scourge here. 

 He also remarked that he had heard that this method was being 

 adopted in America for the same purposes with good results. He 

 knew much more than I did about the practical results of it being so 

 widespread, so I simply listened attentively to what he had to say of 

 its practical utility and didn't tell I had ever heard of it before. He 

 also added one thing I was greatly interested in, and that was the 

 statement that they had found all of their lighter twigged sorts came 

 safely through the winters oftener, while the purple ones v/ere tender- 

 est of all; that they did not understand this till the principle resulting 

 in the whitening was discovered by them." Prof. Whitten remarked 

 that the work done on whitening here was before they began its 

 use there, so that I have no doubt but what they got the idea Trom his 

 bulletin on the subject. Very truly yours,

Discussion. 



A Question : I would like to inquire what is the latest peach 

 that we have? 



Sec, Goodman : I think that I can answer that question. Billue's 

 Late October or Henrietta. 



Mr. Hopkins : The Bonanza was later with me this year. 



A Question : Does the peach yellow ever show itself in the year 

 old trees, or in the nursery, or is it not a disease that requires age to 

 produce? 



Prof. Johnson : No, sir; usually shows in trees after they become 

 of some size. 



A Question : I want to know whether it pays to spray for this 

 rot? 



Prof. Howard : Since I have been connected with the Station we 

 have not conducted any experiments in spraying peach trees, that is 

 scientific experiments, but we have no doubt that those rots can be 

 largely controlled by judicious use of Bordeaux mixture. The am- 

 moniacal of carbonate solution is best for fruit trees because it does 

 not injure the foliage.
