(Original.) infested sections have afforded a large amount of relief from the injury which this insect causes. Each year more or less territory has been found infested by the gipsy moth where the pest was not previously known to exist, so that the territory now known to be infested covers in the aggregate about 7,900 square miles. (See PI. XIII.) At a conservative estimate three-fourths of this area consists of wooded land, while the balance is made up of residential sections, orchards, and farm lands. While the States in the infested section and the United States Government have done much work in the residential sections and along some of the principal roadways, it has been impossible to inspect the large forest area so as to determine the present state of infestation. So long as some of these areas remain badly infested it is difficult to prevent further dissemination of the gipsy moth. The methods adopted of keeping roadways clear has undoubtedly been a factor in preventing.
