and got one, called the spray motor, manufactured in London, Ontario. 

 This was arranged altogether differently from the one we tried before. 

 Instead of mixing it, the petroleum was put in one tank and the water in 

 another. It was drawn by a separate hose and is mixed as it goes through 

 the nozzle. It is the best machine I have struck, by all means the best; 

 it sprays more accurately, and it is the easiest pump to work we have 

 had anything to do with, and so far as I can see it is the best thing we 

 have yet invented for the use of crude petroleum mixtures, and if we do 

 anything with the crude petroleum we generaly do it with the spray motor 

 pumps. I think they will manufacture them on this side before a great 

 while so we will not have to pay duty on them. The price depends upon 

 the size. The price of the one I got is $35, and if you can get them to 

 throw off the duty that is all it will cost you. I was in a hurry and I 

 did not care about the duty. 



I shall say a little more about the other spraying, because I know 

 there are some here greatly interested in it. We have never been able 

 to manage the codling moth satisfactory. We have been puzzled to know 

 what was the matter, whether it was defective spraying or why it was 

 that we could get the apples up until about this time, and then they 

 would drop off in spite of all that we could do. 



Last year, in a small way, we thought we would see if there was any- 

 thing we could do to indicate where the trouble was. So I went up near 

 the lake shore, just east of Toledo, and went into an orchard the day after 

 the spraying was finished. They had sprayed with Bordeaux mixture,, 

 with paris green added, three times. The next day after the spraying 

 we covered a tree with this material you use to cover your pea(jh baskets; 

 with, that makes the peaches have a nice color. Well, we took that ma- 

 terial and we covered the entire tree with it. Of course, you know you' 

 can not get two trees just alike in an orchai'd, but we took another as a 

 check as nearly like it as we could get, and I will tell you what we did: 

 We removed all the fallen apples from under both trees August 9; they 

 were sprayed the last time the 23d of 'June, and covered the 23d. On the 

 14th of September, which you will remember was immediately after a ter- 

 rible wind storm which spoiled acres in Ohio and Indiana, there were 

 removed from under the tree that was covered 229 apples; 59 per cent, 

 of these were sound. From under the uncovered tree there were removed 

 1,052 apples, not over 10 per cent, of which were sound. The cloth was 

 drawn over the tree and fastened at the trunk underneath. We took the 

 apples out from under the cover and then replaced it. October 22 there 

 were picked fi'om under the covered tree 372 sound apples, 8 wormy. Of 

 the windfalls, 18 were wormy. From the checked tree, the one that had 

 not been covered, we picked 253 sound apples, 41 wormy. Of the wind- 

 falls, 104 were wormy and 94 were sound. 



Recapitulation: The covered tree, after the fruit was removed from 

 beneath, on August 29, carried 622 apples. Of these 372 were gathered
