The common white ant, Termes flavipes, destroys dead wood, stumps of trees and timber, just as does its nearest relative, T. lucifugus, in Europe. Of the latter species some cases are reported where living pines and oaks have been destroyed in the South of France. For T. flavipes, only one case is known, in which living grape vines in a hot house in Salem were injured. (S. H. Scudder. Proc. Boston, N. H. S., vol. 7, p. 287). Now the earth in the hot houses here in Cambridge is largely infested by white ants, but as far as I know, no destruction of plants has been observed. I was very much interested by the information from Mr. F. W. Putnam that in a garden in Irwing street living maples were largely infested by white ants. The evidence of the truth of this information was apparent by the first glance at the trees.
