Maine ; its further appearance within our borders is doubtless 

 only a question of time. It behooves the residents of south- 

 eastern New Hampshire to be constantly on guard against this 

 pest. Any time in fall, winter, or spring when one can find 

 upon a tree a curled leaf containing a host of tiny caterpillars, 

 the significance of the fact should be fully realized. For it is 

 probably a colony of these pestiferous insects ; the leaf securely 

 packed in a tight tin box, without air holes, should be sent to 

 the station with a full statement regarding the finding of it. 

 All others of the nests should be promptly burned. 



The Gypsy Moth, also, we must always be on the watch 

 for. It seems as yet not to have gotten a foothold in the state, 

 but it is so abundant near us and there are so many possibili- 

 ties of its introduction that constant vigilance against it is also 

 necessary. 



No further injury from the Elf-leaf Beetle 1 has been re- 

 ported, although it is probable that the insect is still present 

 where it first appeared at Conway Center. This is an insect 

 which owners of elm trees should be always watching for, as 

 it is important that measures for its eradication be taken when 

 it first appears in a community. 



Canker-worms continued to be locally destructive in many 

 parts of the state. Our observations showed that the Spring 

 Canker-worm 2 was much more abundant in Durham than the 

 Fall Canker-worm. We made many observations upon the 

 life-history of this insect which will be reported at an early 

 date. 



The small apple crop of 1901 and the large one of 1902 ap- 

 parently combined to render the damage done by the Cod- 

 ling Moth 8 comparatively small. The wet weather helped 

 to make the attack of the apple scab fungus unusually severe, 

 but the fruit on the whole was surprisingly free from apple 

 worms. The recent investigations of several entomologists 

 have shown that the benefit of spraying with poisons against 

 this insect depends very largely upon getting the particles of 

 poison into the blossom end of the young apples when the
