This pest, which makes for itself a nest out of the leaves of the tree it feeds on, and has these nests hanging on the branches like brown curl-papers over a lady's head, is so easily kept down by hand-picking before they get large enough to be very destructive, that there is not the slightest excuse for having valuable evergreens destroyed by them in our public squares and city parks, as we may so often see them.

When trees die from this cause city gardeners, or superintendents of public squares, should be promptly dismissed.
