This destructive maple borer continues'its operations in the beautiful shade trees ornamenting the village streets in the State. It appears to be particularly destructive in the central western part, and our attention has re- cently been called to severe injuries which were observed by us some seven years earlier. The maples in the village of Le- roy, N. Y., appear to have been excep- tionally unfortunate so far as attacks by this species are concerned. A consider- able number of trees are infested by the borer and not a few have been severely injured. Earlier observations and work have shown the practicability of freeing infested maples very largely from this pest. Inhabited galleries should be care- fully investigated and exposed until the borer is found and destroyed, either with a hooked wire or with a knife. Such wounds should be carefully dressed with a protective material, one of the best of which is a thick, pasty mixture of fresh air-slacked lime and cow dung. A covering of tar or a cheap paint is also very effective in protecting the exposed wood from fungus infection and further insect operations. An exceptionally interesting observation on the work of this insect was made in connection with a recent trip to Leroy. Seven years before, namely, in September 1899, ^^^ photographed a tree in that village which had been badly injured by thi
