54 THE DISPERSION OF THE GIPSY MOTH. 
In 1911-12 14 woodland infestations of 59 egg clusters and 22 
orchard and roadside infestations of 202 clusters were found east 
of the railroad. The woodland infestations were in the territory 
between the Milton railroad station and, the south end of the town. 
In the part of the town west of the railroad only the roadsides and 
orchards were examined, and 6,602 egg clusters were found in 57 
localities. 
The results of scouting in this town show that the infestation is 
increasing rapidly in both woodland and orchards. The figures for 
the two years are significant, for in the western part of the town 
the infested localities in one year more than doubled, and the number 
of egg clusters was more than 40 times greater than the previous 
year. 
RECORD OF SCOUTING IN TILTON, N. H. 
Examination of Tilton, X. H., was begun Xovember 1, 1911, by 
Mr. C. E. Boardman and a crew of experienced scouts. The area 
of the town is about 10 square miles, less than one-third of this 
being wooded. According to Mr. Boardman's estimates the tree 
growth is as follows : 
Per cent. 
Conifers 30 
Oak 13 
Maple 35 
Ash 2 
In 1910-11 the roadsides and orchards in the town were scouted, 
and four infestations containing 889 clusters were found. In one 
of these over 800 clusters were treated, and during the following 
summer over 4,800 caterpillars and pupa? were destroyed under 
burlap. As a result of the present scout only 11 egg clusters were 
found in three orchard and two woodland infestations, one of the 
latter being near the bad infestation of the previous year. This 
shows that good work was clone in controlling and reducing the 
infestations found and that reinfestation by natural or artificial 
spread in this area has been slow. 
Tilton is located 20 miles north of Concord, X. H., and most of 
the badly infested area lies to the southeast; some, however, is near 
Concord and extends to the south. 
RECORD OF SCOUTING IN BENNINGTON, N. H. 
Bennington is located about 25 miles west of Manchester, N. .H. 
The land in the eastern part of the town forms a part of the 
watershed of the Merrimac and Contocook Eivers. Almost one-half 
of the area is wooded. An examination of this town was begun 
Per cpnt.
