GIPSY MOTH WORK IX NKW ENGLAND. 29 
BROWN-TAIL MOTH SCOUTING. 
The spread of the brown-tail moth is not easily controlled by arti- 
ficial means unless the insect can be reduced to minimum numbers. 
Owing to the large territory over which tin 4 insect has spread, it is 
not possible to carry on extensive scouting or control w r ork by the 
use of hand-suppressive measures. During the year a considerable 
area, however, has been examined in Maine, New Hampshire, Ver- 
mont, Massachusetts, Connecticut, and New York, and areas have 
been found infested where the insect was not known previously to 
exist. The work of the commissioner of agriculture of Vermont and 
his assistants has been very effective in reducing the infestation in 
that State. The principal new- infestations were found in Connec- 
ticut, and a greater part of these were located by the assistants of 
the State entomologist. Several webs have also been found on 
Fishers Island and Long Island, N. Y., so that, in all, four towns on 
these islands are known to be infested. The New York infestations 
were discovered by the inspectors employed by the State department 
of agriculture, and several scouts from this office were sent late in 
the spring to check up the work and cover a part of the area 
concerned. 
QUARANTINE WORK. 
The quarantine work is supervised by Mr. D. M. Hogers, who is 
assisted by Mr. Harry W. Vinton, and the operations are confined 
to the territory in New England and New York which is infested 
by the gipsy moth and the brown-tail moth. As a result of the 
provision of the Federal plant quarantine act, which was passed 
by Congress August 20, 1912, a domestic quarantine 1 has been 
declared by the Federal Horticultural Board, covering the territory 
infested by each of these insects. While the legal authority for 
declaring quarantine is vested in the board, the cost of adminis- 
tering the work is defrayed by the appropriation for the Bureau 
of Entomology for " Preventing the spread of moths." The object 
of this work is to prevent egg clusters or larva? of the gipsy moth, 
or winter webs of the brown-tail moth, from being carried out of 
the infested areas on shipments of trees or forest products. The 
regulations for enforcing this quarantine provide that all material of 
this character before being accepted for shipment to points outside 
the infested district must be inspected and must be accompanied 
with an official certificate of the Federal Horticultural Board stating 
that an examination has been made and that the material is free 
from infestation. Shipment of Christmas trees and similar material 
to points outside the quarantined area is prohibited. In order to 
facilitate the work, the infested territory has been divided into 22 
sections and a competent inspector has been placed in charge of
