The point of infestation referred to outside of the region about 
Boston is in the city of Providence, R. I. This infestation has been 
made the subject of a special report by the Rhode Island State board 
of agriculture, namely, Bulletin No. 13, published September, 1901, 
by the late James M. Southwick, curator of the Roger Willams Park 
Museum. The discovery of the presence of this insect in Providence 
was made in July, 1901, and was investigated thoroughly at the time 
by Mr. Southwick, with the assistance of Prof. A. H. Kirkland, who 
was called down from Boston. When discovered the gypsy moth was 
confined to the west side of Providence, where it was established in a 
half dozen or more distinct colonies. The occurrence of these distinct 
centers of infestation, all of apparently the same age, in the heart of 
the city, leads to the suspicion that the insect may have been malici- 
ously colonized at these separate points. It is impossible to believe 
that these distinct colonies should have been accidentally started in 
Providence at the same time, especially in view of the difficulties in 
the way of the transportation of the gypsy moth and its very slow 
spread about Boston, as indicated by its history during the last thirty- 
six vears. The infestation in Providence illustrates one of the great 
dangers from the gypsy moth. It is readily spread by carrying egg 
masses, and maliciously-inclined individuals can thus easily start new 
colonies at any distance from the present infested area. In view of 
this, as emphasized by the Providence infestation, it is highly desir- 
able that heavy penalties be provided for any malicious colonization 
of the gypsy moth. The important points of infestation in Provi- 
dence are indicated on the accompanying map (fig. 2). The writer 
was assisted in locating their exact position by Messrs. Joseph D. 
Fitts, supervisor of parks, Providence, and C. A. Davis, present 
curator of the Roger Williams Park Museum. At the present time 
these colonies are still in existence, in spite of local work done in the 
way of control. Notable stripping has not occurred this year, but the 
larvee and pupz were easily discovered at the points of infestation, 
and there is, therefore, opportunity for much increase in the future 
and a repetition of the experience about Boston. 
MEANS OF CONTROL. 
The work of the gvpsy moth committee of the State of Massachu- 
setts developed a number of means of controlling the moth of the 
highest practical value and efficiency, and nothing can now be sug- 
gested in the way of improvement on these methods. The general 
adoption and enforcement of these will undoubtedly keep the gvpsv 
moth in substantial control, so that no material damage to woodlands 
or to shade trees in residential districts need be feared. In the case 
of small properties, or where but a few trees are to be protected, these
