DISCUSSIONS AT GRAND HAVEN. 367 



Mr. E. M. Potter said that the miller, which was transformed from the moth 

 in the first apple, deposited eggs in the remaiuiug apples. They should be 

 caught by wrapping tli'^ bodies of the trees with bands of cloth or paper — 

 cloth was the best, — and the bands removed and the moths caught once in a 

 week or ten days. 



Mr. A. Fitch put bands of cloth four inches wide just below the branches. 

 He found the strings a bother, and used a tack where the ends of the bands 

 lapped. He don't fail to find all by turning the cloth up and down without 

 taking off the band. Thinks the bands ought to be examined as often as once 

 a week, as in that time he finds the millers beginning to eat out of the cocoons, 

 and if deferred longer some have gone. Found only one curculio on the apple 

 trees. 



Mr. D. B. Williams said he had less than two weeks' experience in catching 

 the codling moth, and in that time had learned and accomplished a great deal. 

 Found that paper or cotton cloth bands were not perfectly reliable, A thick 

 woolen cloth was the thing, wrapped around the trees and the ends tucked un- 

 der, fastening it quickly without string or tack. Kext to woolen cloth a band 

 of June grass was good, these being put in a pile and burned when taken off. 

 In two or three days these would be fairly stuck to the bark by the web of the 

 moths. He let chickens pick off the worms, but they would not touch the 

 cocoons. He caught thirty or forty on a tree in three days after putting the 

 bands on. He laid an old woolen glove in the crotch of a tree and found 

 fifteen moths on it, besides several under scales of bark under it. Notices that 

 where two apples touch each other a moth has entered. 



Mr. H. Chatfield said two weeks ago he put bands about his trees, and to-day 

 on examining them, found from ten to sixty on a tree, in all stages of develop- 

 ment, from the worm to the empty cocoon. Some seemed to have gone down, 

 and some up, from fallen apples on the ground. Think there were fully as 

 many above as below the string. Where he found moths under the scales of 

 the bark a web was attached to the cloth. Did not find many on bands of fac- 

 tory cloth, but most on dark thick woolen cloth. 



Mr. A. S. Dyckman had caught a great many, both under paper bands and 

 cloth. He put them on in June, but did not catch many until in July, and 

 most of them recently. Looked for them once a week. 



Mr. S. Gr. Antisdel, of Benton Harbor, said he saw a strip of paper which 

 was taken the third time from a tree at that place in ten days, and it was com- 

 pletely covered with the web and cocoons of the moth. 



Mr. D. T. Pierce said the red-headed woodpeckers were eating his apples. 



Mr. A. J. Pierce put bands of cloth and paper around his trees two weeks 

 ago. He don't find many, though the apples are wormy and falling off. 



Mr. D. C. Loveday said paper bands he put around his trees were perforated 

 with holes, as though peppered with shot, and under the paper, close to each 

 hole, he found an empty cocoon. He supposed the millers had eaten out. 



Mr. J. Williams said the only way to exterminate these moths was for every 

 man to be interested in the work. It was of little use for a man to destroy 

 them when his neighbor was propagating them. His observation convinced 

 him that the best way was to trap them as we did the curculio, with the chip 

 trap ; then scrape the rough bark off and place bands just below the branches. 

 They could not all be caught under the bands when there was grass and rub- 

 bish under the trees. He caught on one tree, in eleven days, sevent3'-two worms. 

 It was necessary that we should co-operate to destroy them.
