The most common and poorest is burning the nests, but many 

 usually escape the effects of this operation, and the tree is 

 likely to be injured. If the nests are taken at the outset 

 this method would be tolerably successful, but where the 

 whole twig can be cut oif it had better be done and l)urned. 

 If the fruit grower is careful these nests will not appear, for 

 he will go over the trees when the leaves are off and hunt 

 up the egg clusters and remove and burn them. Strong 

 soap suds, kerosene, or other such applications, in the nests 

 would destroy most of the worms, but if the nest is the point 

 of attack they must be assailed at the time when the worms 

 are in them, that is duting the night, or early in the morn- 

 ing. A few wild cherry trees near an orchard would be a 

 great protection, as the moths lay their eggs on these in pref- 

 erence to apple trees, and they can be attacked on these 

 trees and the apple trees go uninjured. 



Another and similar species of tent caterpillar is exten- 

 sively found in forests, and this sometimes visits orchards. 

 There is a small, dark colored moth known as tlie bud moth 

 which sometimes does much damage to the apple trees. 

 This moth, Penthina oculana, Ilar.^ is about one-half inch 

 across the expanded wings, its head and thorax- are dark ash 

 color, as are the ends of the wings, but the middle of the 

 wings is grayish, and there are two small eye-spots on each 

 wing. The hind wings are dusky brown. The larvse are 

 pale brown, warty and somewhat downy, the head and upper 

 side of the first wino- beino; of a shining brown. Thev are 

 found in May and June on the buds and young leaves of the 

 apple trees devouring the leaves, or fastening tliem together. 

 About the middle of June, or a little later, they become
