PROCEEDINGS OF THE SUMMER MEETING. 137 



A. Almost all kinds of tree. So far as I know, there isn't a 

 thing it does not attack. I should fear almost any tree I had — certainly 

 all fruit trees, and all plants except the strawberry. 



Mr. Graham: What means should we employ to protect ourselves 

 from these scales and from the aphis? We have already had the aphis 

 shipped in here. A carload was distributed throughout Kent county. 

 You can not see that with the naked eye. They were discovered merely 

 b}^ accident. The man who bought them thought he discovered an odor 

 of fcarbolic acid on the trees, and he investigated. 



Prof. Taft: In that case you could not do very much, if you did not 

 know it was there; but with all the danger we have, I think we should 

 have a quarantine law, compelling all trees to be examined and passed 

 upon by competent authority. It seems to me, too, our spraying laws 

 should cover this class of insects, from the fact that they are far more 

 likely to do harm than those we have been spraying for in the past. 



Mr. Smith: One of my neighbors has a plum tree which was full of 

 blossoms this year. Instead of there being plums on it, it was a kind of 

 sad: which sometimes had an insect in it and sometimes not. There 

 wasn't any seed. 



Prof. Taft: I spoke of that this morning, the plum-bladder or plum- 

 pockets. It is caused by something like the same fungus which causes 

 leaf curl of the peach. It is almost the same fungus. Where a tree 

 is badly infested you wouldn't be able to save all your fruit next year, 

 probably, but by all means pick off and burn all those which develop, and 

 spray the trees to destroy the spores. The next spring, give them the 

 ordinary spraying that you would for that or anything else — spray in the 

 spring before growth starts, and again as soon as the blossoms have 

 fallen, and after a year you should be entirely free from it. 



Mr. Judson: Is the spraying law enforced? A. I am sure that the 

 agitation over that law has led to increased spraying. So far as I know, 

 however, no cases have been brought under the law. 



Mr. Graham: In Kent county the law has been enforced in a small 

 way. 



Mr. Sherwood: Could this trouble mentioned this afternoon be 

 avoided by dipping the trees? A. I would certainly always do that. 



Mr. Graham: The trouble is, they are not observed by the ordinary 

 man, neither the aphis nor the San Jose scale. We do not examine them, 

 and nothing calls our attention to them. Now, it seems to me there 

 should be some quarantine or something of that kind to prevent the 

 introduction of these pests into the state. Other states have such laws, 

 and it seems to me if anyone should take action in that matter it is the 

 State society; it should push the matter and have some action taken, 

 either by resolution or some other w^ay, to prevent the introduction of 

 these pests into the state. 



Mr. Morrill: When we get oranges in this market from California, 

 which have live scale insects on them, isn't there a strong possibility of 

 our introducing scale in that manner? 



Mr. Graham: Certainly, there is great danger of it. Many of our 

 plants are different from those in California, but unquestionably some of 

 our plants would be troubled by the scales that come from there. I am
