much less in this State than in the cities in New Hampshire noted 
in Table VI, which is due largely to the fact that the region is out of 
the line of natural spread and reinfestation by the wind. 
The common trees growing in Rhode Island are as much if not 
more favored for food than those in the cities mentioned.

The record of infestation — that is, the record showing the number 
of egg clusters found while scouting various towns from year to 
year — is interesting, as it gives in a way the rate of increase, although 
it should be understood that all egg clusters which are found are 
treated with creosote, and in most cases the infested areas are 
attended to during the caterpillar season and all the larvae found are 
destroyed. Only roadsides, orchards, and private estates are ex- 
amined and treated. In most cases the towns have large woodland 
areas which it is impossible to examine owing to the expense involved. 
The record of the infestation is given for several towns, which shows 
that dispersion must be due to causes other than vehicles. 
The data for the town of Easton were furnished by Mr. L. W. 
Hodgkins, an agent of the State forester of Massachusetts, who had 
charge of a section of southeastern Massachusetts for several years. 
The town has been examined and the infestations treated each year, 
the number of egg clusters showing a slow but continuous increase 
since 1906, the year when the first infestation was found. During
