gipsy moth office at Somerville, N. J. Mr. Ames works under the general 
supervision of Mr. H. L. McIntyre, chief of the U. S. field service 
against the gipsy moth. 
As the work has gone forward definite methods of record keeping 
have been developed and it has been deemed wise to make up the tabular 
statement in accordance therewith.

The preceding tables bring out the fact that while the amount of 
money being used is large the infestation is being rapidly reduced, both 
as regards number of colonies and number of egg masses. The data for 
1922 is, of course, still very incomplete. The fact that with only about 
% of the territory scouted 404 egg masses have been found, might lead 
one to conclude that more eggs will be found this year than last. One 
must, however, take into consideration the fact that much of the scout¬ 
ing in the general area this year has been done along the river banks 
Ttems of funds, machinery, banding, number of trees sprayed and lead arsenate 
used include the isolated areas as well.
