was received from Middleton, Canyon County, Idabo, and, tlirough Mr. 

 James Fletcher, from British Columbia. 



The New Jersey investigation of the insect the Department of Agri- 

 culture has not touched. It is in the safe hands of Dr. Smith, who has 

 promised a paper upon the subject for this meeting. He has also 

 visited the locality at Atgien, Pa., and found that in an orchard of over 

 7,000 trees all of certain varieties and a few of others were infested by 

 the scale. As a result of his recommendations, kerosene emulsion has 

 been applied three times to most of the trees, at intervals of ten days, 

 up to the first week in June. The treatment has been absolutely suc- 

 cessful. 



The other Pennsylvania occurrence was at Lewisburg, Union County. 

 Dr. G. G. Groft', of the board of health, in 1890 bought one dozen Buf- 

 fum pear trees from a Xew Jersey nurseryman. One after another 

 died, until but one remained. Six months later he bought one dozen 

 Lawsons from the same firm. Several of these were infested and after- 

 wards died. The insects hatched prior to the time of writing spread 

 slowly among the trees. The remedial measure adopted prior to writing 

 to the Division was the dampening of a cloth with kerosene and wiping 

 all the affected parts of the tree by hand. The orchard in this case 

 was small, and the owner was able to destroy the majority of the insects 

 by hand-rubbing. We advised him to spray with kerosene emulsion 

 during June, but have not learned whether he considered it necessary 

 to adopt this course. He seemed fully alive to the importance of ^>be 

 matter, and on account of his intelligence and scientific ability we have 

 no doubt that he has exterminated the insect on his trees. 



The Indiana occurrence was, as above stated, at Bartle, Washington 

 County. Two young apple trees were found affected by the scale, and 

 the owner burned them, previously cutting off" twigs, which he sent me 

 May 8. On the 2Cth of June he wrote that he had made a most careful 

 examination and could find no more of the insects. These trees were 

 bought and planted in the spring of 1891, and were purchased from a 

 firm of New Jersey nurserymen. 



The occurrence at Neavitt, Talbot County, Md., is in an equally sat- 

 isfactory condition. The orchard is located on one of the inlets of the 

 Chesapeake Bay, and contains about 14 acres. Specimens were first 

 received May 19, and full directions as to remedies were sent. As a 

 result the trees most badly infested were destroyed, and spraying opera- 

 tions were begun. During July we sent Mr. Coquillett to visit the 

 orchard. He found that 10 acres were set out to peach trees eight 

 years ago, that nearly all these trees are now affected by the San Jose 

 scale and are in a languishing condition. At the time of setting out 

 about two dozen were left over, and these were disposed of to a neighbor, 

 who planted them in one corner of his orchard a short distance away. 

 The remaining 4 acres of the first orchard are set out to ])each, apple, 

 plum, cherry, and x)ear, and range in age from 1 to 6 years. Almost
