No. 4.] THE GYPSY MOTH. 465 



although in some cases they make an attempt to rcfoliate. 

 Where the moth is not numerous enough to destroy the 

 greater part of the foliage, or in cases where it has been 

 checked by the men before it has finished its work, some of 

 the trees revive, while others linger, perhaps, for a year, 

 sicken and slowly die. 



The scene in the Lexington woods, of which two views 

 are given, one taken in 1895, the other in 1898, well illus- 

 trates a case of this kind (Plates VII, VIII). The photo- 

 graph from which the first plate was made was taken in 

 L895, just after the caterpillars had been destroyed by the 

 workmen of the gypsy moth force. The leaves were 

 stripped from a considerable area here, and several pines 

 were partially defoliated, one or two wholly so. The large, 

 vigorous pine in the foreground, which, as may be seen, 

 had not been wholly stripped when the men checked the 

 progress of the moth, threw out some new foliage and 

 appeared to revive for a short time, but before the end of 

 the season it seemed to be dying, and in 1897 was unde- 

 niably dead. The picture taken in 1898 shows the remains 

 of this pine, with other trees in the background, the pine 

 dead and much eaten by wood-borers, the bark now falling 

 off, and many of the oaks in the same condition. 



In 1897 a number of large pines and hemlocks were killed 

 by the gypsy moth in the Saugus woods, in the face of all 

 that could be done by the agents of this Board to prevent it. 

 They were situated in different localities, the pines being 

 about a mile from the hemlocks. The hemlocks, some five 

 or six large trees, were completely stripped, and never 

 showed a sign of life afterwards. All but two of these trees 

 were cut down. These two are yet standing. The pines, 

 two very large trees at some little distance from each other, 

 were nearly stripped. They failed immediately, and were 

 evidently dead by the summer of 1898. 



In 1896 there was a badly infested spot in the woods on 

 Meeting-House Brook, adjoining and to some extent within 

 the border of the Middlesex Fells reservation in Medford. 

 The colony had spread into the reservation from the woods 

 outside, where the ground was thoroughly burned over with 

 oil in the spring to destroy any scattered moth-eggs. This
