 were constantly employed during the month of May in collect- 

 ing and destroying the larvae taken out of the limbs that had 

 broken off as the result of their burrowings. After every high 

 wind, wagon-loads of branches were gathered from the ground 

 and burned. It was being combatted by every possible 

 means, not only by burning the fallen limbs, but by removing 

 from the trees those that by their changing color or withering 

 gave indications of infestation, and also, in the case of the 

 rarer trees, searching for an opening to the burrows and jn-

 abundant evidence of its presence. It had also spread,

 Jamaica, New Lots and Flatbush, on Long Island. The

Already many of the larger elms in Central Park have had 

 their symmetry and natural beauty greatly impaired through this 



but such a result might follow should the insect become suffi- 

 ciently numerous to invade the entire tree. We do not know 

 that any better methods can be used to arrest this increase 

 than those that are employed at present at Central Park, 

 unless some means may be devised for destroying the eggs of 

 the moth before the hatching of the larvae and their entrance
