season. The present season it is safe to say that all the upper region 
of the town is tree from the insect. A few scattered larvae seem to have 
been brought in from the Saugus woods, but all of the old colonies are 
practically extiuct. 
W ALT 1 1 A.M. 
All of the old colonies in this town were practically exterminated 
previous to 1895. In 189G one colony was found in the woods, which 
was carefully watched, burlaped, and treated in such a way as to 
promise extermination. Examination of this colony in 1897 shows that 
this work was effective. A single white-oak tree at the border of the 
colony, however, probably harbored a single egg cluster, as a few cater- 
pillars were captured. Probably no more work will be required in this 
town, although the locality just mentioned will be carefully watched 
another season, and eventually another tree to tree inspection will be 
made. As Waltham is one of the border towns, this result is most 
encouraging. 
WATERTOWN. 
Although this town contained numerous colonies, all but two had 
been exterminated by the close of 1890. The 1897 inspection showed 
that in one of these the insect had been exterminated. The other is an 
extension of Mount Auburn Cemetery, in Cambridge, which has already 
been mentioned under the head of Cambridge. Very few caterpillars 
were found there this summer. 
WINCHESTER. 
The Winchester woodland contained a part of one of the badly 
infested wooded localities reported upon in 1895. Careful work was 
done in 1896 in the western Winchester woods. It was followed up by 
careful winter work. Considerable tracts were cut over and burned 
over, then inspected and -burned again. The numbers of the insect 
were very greatly reduced and very few individuals can now be found 
there. In one of the worst colonies 33 acres of woodland was cut 
over by the owners and the brush burned off by the committee and 
the ground and sprouts burned over. No evidence of the insect has 
since been found in this tract of land, except at two points on the out- 
skirts, where the wood was not cut and where a few caterpillars have 
been trapped this summer. In another colony the committee cut off 
the wood from about 19 acres and this wood was marketed by the 
owner of the land. In the southeastern borders i){' the town is a tract 
of tanning land where there have been strips oi' badly infested wood- 
land. Much of this was cut and cleared up in the spring of L897 and 
vast numbers of eggs destroyed by tire. This work and this summer's 
burlaping has so greatly reduced the insect as not only to prevent its 
spread, but to promise practical extermination almost in a single sea- 
Son. In the residential portion of the town the condition is excellent 
and only occasional caterpillars are found.
