Mr. William Doogue has made a report to the Committee on Public Grounds, of the city of Boston, which has been officially published. He says that the city owns 22,254 trees. Some have proposed a heavy appropriation from the taxes to clear these trees of cocoons and the eggs of insects. He shows that with the vast number of unclean-ed private trees, and forests, the money would in a great measure be thrown away. Also by facts ranging from 1848, to the present time, that insects appear and disappear in these large quantities periodically, probably because their enemies follow and prey on them. He thinks horses, bad pruning, and other injuries, wholly within human control, are far more destructive to street trees than the insects; and it is because trees are so thinned out by these neglects, that the insects crowd to the trees that are left. He believes that if more attention were given to these matters, the trees so far as insects are concerned, might be safely left to the birds and other natural causes.
It is a very sensible document, and the Committee have shown good sense by adopting it.
