For the first application, which should be made as soon as the 

 buds beg-in to swell, London ptirple need not be added to the Bor- 

 deaux mixture, but for the second, third and fourth application it 

 should be included. The second application is to be made just be- 

 fore the bloom opens, the third when the petals are nearly all shed, 

 the fourth when the fruit is about the size of peas and the fifth about 

 two weeks later. 



The profitableness of spraying apples, so far as the control of the 

 scab is concerned, will depend upon the susceptibility of the variety 

 and the likelihood of the appearance of the disease without treat- 

 ment. Trees affected as little as either the Early Harvest or the 

 Wine Sap would hardly pay the cost of spraying, so far as this one 

 disease goes. 



But upon general principles we firmly believe that it will pay to 

 spray all apple trees with a combined fungicide and insecticide, 

 inasmuch as there are other foes than the scab fungus to be com- 

 batted by the treatment. Of these we have the various fruit rots, 

 leaf blight and that very formidable enemy, the codling moth. 



Furthermore, there is reason to believe that the general health 

 of the tree will be so greatly improved that this alone will make the 

 spraying of apple orchards a profitable expenditure. 



RUST VS. FROST ON STRAWBERRIES. 



President Underwood: I will say that Mr. West has received 

 a sample of his strawberry vines he spoke about on Tuesday 

 as being afflicted with rust. I asked him more particularly as 

 to the condition of the vines . I see nothing like rust on those 

 vines. It is not what I call rust at our place. He says it did 

 not appear until after the first heavy frost came, and then they 

 began to turn brown. I think they were in good condition 

 when the first heavy frost came, and the alternate freezing and 

 thawing produced the appearance he calls rust. 



Mr. C. F. Gardner, (Iowa): I would like to say that my 

 vines after some of those severe freezes looked as though 

 they were struck with rust, and I made a close examination of 

 them, but I could not find a particle of rust. It was caused 

 altogether by the frost. There was no rust on those vines, 

 and I know there was not on ours. Still a little ways off it looks 

 just like rust. 



Mr. G. J. Kellogg, (Wisconsin): I should say there was no 

 rust on those plants. It maybe a little hard to distinguish 

 except on close examination, but I think the appearance of 

 those vines was caused entirely by frost. 



Mr. C. L. Smith: That again corroborates what I said the 

 other day, that it is beneficial to give your strawberries a light 

 covering early in the fall before they are subjected to any severe 

 frosts.
