from 80 to 99.9 per cent. In one colony, where in 1897 

 41,843 egg-clusters were killed, in the fall of 1898 only 

 43 were found. In another colony 58,390 egg-clusters of 

 1897 were killed, while in the fall of 1898 only 18 were 

 found. 



Notwithstanding the great improvement in the condi- 

 tion of these woods, caterpillars will probably be found 

 scattered through them in the spring of 1899. Nearly all 

 the Medford woods, therefore, will have to be burlapped. 

 In anticipation of this, the undergrowth has been already 

 removed from most of this infested woodland and the dead 

 and dying trees have been cut. There is still an area of 

 several hundred acres partly grown up to brush which 

 should be cleared before spring opens. When this has 

 been done, it will be necessary to keep down the under- 

 growth for two or three years, and each year to burlap and 

 inspect thoroughly all these woods. To do this will require 

 for the next three or four years nearly as large a force of 

 men each year as was used there in 1898. 



Everett. 

 Owing to the delay of the appropriation, it was impos- 

 sible to inspect Everett thoroughly and destroy the eggs of 

 the gypsy moth before they hatched, therefore the cater- 

 pillars were widely scattered through the city in 1898. The 

 trees on every street were burlapped, and the number of 

 egg-clusters in Everett at the present time is much less than 

 the number left in the spring of 1898. When the burlaps 

 were taken off, the trees were looked over and all the eggs 

 seen were destroyed ; but the whole city should have a 

 thorough and careful inspection before the eggs hatch next 

 spring. This will be possible if an early and adequate 

 appropriation is made. The land in Everett being cleared 

 and the trees being mainly shade and fruit, there should be 

 no difficulty in exterminating the moths, provided the 

 requisite means are promptly given to do all the work 

 necessary each year in the city, as well as exterminate the 

 moths from the adjoining cities of Maiden and Medford.
