It has not usually been found on the apple. Possibly it 

 has been due to the dry weather. The last two seasons 

 have been particularly dry, and that may account for it. 

 We have had it on the pear for years, but never before on 

 the apple. It is rather interesting to note that this did se- 

 rious damage in New York state for a couple of years. It 

 seems that New York sets the style in insects as well as 

 everything else, and if there is any new pest comes along, 

 why, New York people have the credit of introducing it, 

 and then we all follow in their wake. This mite, I would 

 say, can be controlled by winter spraying with lime and 

 sulphur, or with ordinary kerosene emulsion. Practically 

 the same treatment as that given for the San Jose Scale 

 will control it. The little mites hibernate in the bark of 

 the trees. They are microscopic, but the mites hibernate 

 in the bark and can be treated the same as for the San 

 Jose scale. This slide shows one of the worst insects that 

 we have had to deal with. As you know, it hibernates 

 over winter in the egg stage, which you see here clustered 

 around the butt, — you can see it in the little shiny black 

 eggs. Here we have .it on the leaf, just as the buds are 

 expanding, and you can see little eggs around it. They 

 are enormously prolific. One of these gives birth to prob- 

 ably fifty or seventy-five young in the course of a week or 

 ten days. These give birth to living young, but the in- 

 crease of the pest is exceedingly rapid. They crawl up 

 upon the foliage, are very voracious, and unless something 

 is done to stop the attack, they are very destructive. Here 

 we have a sample of what they can do on this twig (in- 

 dicating). Of course, we can see where many myriads of 

 these little mites are clustered upon a tree or upon the 

 foliage, sucking the juice from it, it very soon seriously 

 affects the trees, causing a loss of foliage, and a general 

 dropping of the vitality of the tree. One danger of this 

 as an insect pest comes from the rapidity with which 

 it reaches maturity. Some great stories are told about
