probably not be able to distiuguish one kind of apple from another 

 when they are both immature ; but the mother Codling moth, as it ap- 

 pears, distinguishes them with ease. And yet almost any mechanic 

 would tell you, that one of these despised 'l^ugs" is as much a mere 

 unthinking machine, as the awl or the needle or the anvil that he 

 himself works with ! 



Almost universally, there is but a single larva in a single apple 

 at one and the same time. But on August 15th, I found a windfall 

 which contained two larvse, one of which had evidently entered at the 

 calyx or blossom end, and the other at the foot stalk. I have noticed 

 a few specimens where the egg had been attached to the cheek of the 

 apple, and the young larva that hatched out from it had made its 

 entry there. And I have also observed that, where two apples hang 

 so as to touch one another, the larva bred in one of them will some- 

 time? be depraved enough, in the mere wantonness of power, to bore 

 out of it into the adjoining fruit, though there is an abundance of 

 food remaining for it in its original home. Probably, on careful 

 search, similar cases of wanton destructiveness might be met with in 

 the human species. 



Others as well as myself — Dr. James Weed, for example, of Mus- 

 catine, Iowa — have observed that the larva of this insect often leaves 

 the apple, before that apple falls to the ground. Consequently the 

 gathering up and destroying windfalls, either by man-power or hog- 

 power, though an excellent prescription so far as it goes, is not an 

 infallible panacea. 



After all, the best and most reliable remedy, so far as my limited 

 experience goes, when we have palliated the evil by destroying the 

 wormy windfalls day after day, is Dr. Trimble's hay-band system; 

 which should be commenced about July 15th and continued till about 

 September 15th, looking under the hay-bands every day or two for the 

 cocoons. The cocoons themselves may be readily recognized by their 

 being composed of a gossamer-like, filmy, white silk, inside which the 

 larva or pupa will be found. On this important subject, I append 

 the following passage, which I find in the Western Rural of Nov. 9, 

 1867. 



'•'A correspondent of the Country Gentleman states that, in the 

 orchard of Dr. Trimble, of New Jersey^ he had an opportunity of wit- 

 nessing the efficacy of what he ca-lls 'Dr. Trimble's remedy for the 

 apple-worm.' Hay-ropes had been wound around the trunks of the 

 trees, and large numbers of insects had been caught, some of which 

 had attained the pupa state, while others having only just reached 

 their hiding-place were still larvae. The whole number of insects
