found there wasn't much difference between the Bordeaux 

 and the commercial lime-sulphurs as to their value in prevent- 

 ing this trouble. But, as I have said, on the whole, in our ex • 

 periments, Bordeaux showed more fungicidal value than the 

 lime-sulphur sprays, but we didn't have such severe attacks 

 of fungous troubles to test out this matter in such shape, as 

 has been the case elsewhere. 



A TvIember: I would like to ask if you would use the 

 same strength of lime-sulphur for plum rot as we do for 

 peach rot, and if we should use them at the same time and 

 the same number of applications ? 



Dr. Clinton : You use it the same number of times 

 and the same number of applications. Prof. Scott recom- 

 mended less sulphur, that is, six pounds of sulphur instead of 

 eight pounds of sulphur. We only sprayed one or two plum 

 trees this year, and I did not see the plums at the time of 

 picking. We only sprayed them twice, and it did not prevent 

 the rot entirely. At least three sprayings would be neces- 

 sary, and you could use Scott's mixture. 



President Rogers : I wish you would call on Mr. 

 Barnes of Yalesville to give us a little bit of his experience 

 in spraying, ^^'e have his apples before us, they are very 

 fine, and he must know something about spraying. 



Mr. Barnes : We did not practice summer spraying at 

 all this year. I think I could not add anything to what has 

 already been said. Our spraying was done in the spring, 

 that is, nothing later than the spraying with arsenate of lead, 

 we have done nothing later than that. 



Prof. Whetzel: You might be interested in the results 

 and observations we have gotten on this question of russeting 

 of fruit. I have here a copy of a recent bulletin of Mr. 

 Wallace and he tested out this question, comparing Bordeaux 

 and lime-sulphurs on several varieties. 



That is to say, in all of our experiments, without excep- 

 tion, all those sprayed with lime-sulphur and arsenate of lead 

 have shown less russeted fruit than those sprayed with Bor- 

 deaux, and less than those that were not sprayed. And I can
