SIXTEENTH ANNUAL MEETING. 151 



this trouble. I think where we have failed so many times is 

 in not using a powerful enough spray to reach to the tops of 

 the trees. When we fail to cover the trees thoroughly with 

 the mixture then we fail to get satisfactory results from our 

 spraying. I think we should get pumps powerful enough to 

 thoroughly cover our trees and try to exterminate this scale, 

 not only on trees of this age and size but all other trees, 

 whether young or old, large or small. 



A Member : My own experience has been somewhat 

 limited along this line, but I believe that old orchards can be 

 sprayed profitably and successfully ; we find the expense of 

 spra3'ing is not great, and believe thoroughly in it. 



Mr. Roberts of New^ Jersey : One of our fruit growers 

 thinks he has solved the problem; he has made a success in 

 spra}'ing large trees by the use of crude oil and it would be a 

 very difficult thing to induce him to use anything else. He 

 says there are tw^o or three things to remember, and those are, 

 plenty of powder, warm oil and not to put on too much. I 

 think the big apple trees take care of themselves better than we 

 think, and that a great many of the orchards will get along 

 without spraying at all. 



Question No. 6, "Along what lines are likely to be new 

 developments in apple growing, as a result of San Jose Scale?" 

 w-as answered by Mr. N. S. Piatt in the following brief but 

 excellent paper : 



Mr. N. S. Pj.att : The Ijackyard apple tree in city and coun- 

 try is beginning to die out on account of scale. Our soil and our 

 climate has favored a*lid would now favor the longest life and 

 largest growth for an apple tree that it attains anywhere. It is 

 through no weakness of tree that it is going out, but through 

 the very robustness of tlie new enemy. The treatment that, 

 according to our best knowledge, is necessary to preserve the 

 trees, either cannot or will not be given and these trees will 

 from present appearances continue rapidly to die out. 



And on the farm the little orchard back of the barn is likely 

 to go soon also. It is often made up of large trees that cannot 

 well be treated. In fact, any trees that cannot be sprayed or 

 that it will not pay t(j spray are likely to succumb tf) the scale. 

 The scale is now not only widely spread as to area but also so
