Eemedies. — 1^0 insect is more readily kept in sub- 

 jection than this. Cut off and burn the egg-clusters 

 during winter, and examine the trees carefully in the 

 spring for the nests from such clusters as may have 

 eluded the winter search. The eggs are best seen in a dull 

 day in winter when they show distinctly against the sky. 

 Though to kill the caterpillars numerous methods have 

 been resorted to, such as burning, and swabbing with oil, 

 soap suds, lye, etc., they are all unnecessary, for the nests 

 should not be allowed to get large, and if taken when 

 small are most easily and effectually destroyed by going 

 over the orchard with the fruit-ladder, and by the use of 

 gloved bands. As the caterpillars feed twice a day, once 

 in the forenoon and once in the afternoon, and as they 

 are almost always in their nests till after nine A. M., and 

 late in the evening, the early and late hours of the day 

 are the best in which to perform the operation. As a 

 means of facilitating their destruction, it would be a good 

 plan, as Dr. Fitch has suggested, to place a few Wild 

 Cherry trees in the vicinity of the orchard, and as the 

 moths will mostly be attracted to such trees to deposit 

 their eggs, and as a hundred clusters on a single tree are 

 destroyed more easily than if they were scattered over a 

 hundred trees, these trees will repay the trouble wherever 

 the Tent-caterpillar is known to be a grievous pest. 



THE TENT-CATERPILLAR OF THE FOREST. 



(Clisiocampa sylvatica, Harr.) 



The egg-mass from which the Tent-caterpillar of th: 

 Forest hatches (fig. 102, a, showing it after the young larv83 

 have escaped) may at once be distinguished from that of 

 the common Tent-caterpillar by its being of a uniform 

 diameter, and docked off squarely at each end. It is usu- 

 ally composed of about four hundred eggs, (the number
