somewhat on the surface before going to the apples. Oc- 

 casionally you can find evidence where the larvae has fed 

 considerably on the foliage. We do not think that this 

 is common in orchards. It is possible in a year when 

 there are no apples in the orchard the larvae might sur- 

 vive by feeding on the foliage, but it is worth}- of note 

 as showing that the larvae can feed upon the sprout. When 

 the larvae has fed a little on the foliage, then they travel 

 to the apple. They may travel quite a little ways. The 

 eggs are laid upon all parts of the tree, whether there are 

 apples on the limbs or not. We found that the average 

 distance of the egg from the apple, however, was about 

 nine inches, so that they have to travel, in some instances, 

 quite a little ways. Now when they get up to about that 

 growth, as you see in the diagram, about two-thirds of 

 them enter the blossom end of the apple. Here we see 

 one of the little caterpillars feeding around in there, be- 

 fore mining into the fruit itself. Now the fact of their 

 entering the blossom is the basis of our spraying opera- 

 tion. They work their way into the core a little at the 

 side, and then go out through the side of the apple, leaving 

 the ordinary worm-hole which we often see. The cater- 

 pillar spends practically a month in the apple feeding and 

 then they come out and spin their coccoons, and same as 

 in the winter, on the bark of the tree. 



Xow in Xew Hampshire we have very few which hi- 

 bernate over winter and transform. They make, however, 

 in the fall, in latitudes where the conditions are favorable, 

 a second brood. Only about two or three per cent trans- 

 form in the way that you see in the picture. They lay 

 eggs on the trees, and the caterpillars hatch, and these feed 

 on the apples, but their habits are quite different from the 

 first brood. They feed more on the surface around the 

 blossom end, and do much damage, as you can cee. Now 

 I am not informed as to what proportion of the -econd 

 brood you have here, but doubtless there are verv much
