VISITS FROM ENTOMOLOGISTS. 69 



The short time remaining before egg-hatching time was util- 

 ized in destroying eggs in the worst- infested towns, and 

 searchino; for them in the outer and less-infested towns. 

 The trees in infested localities were banded with burlaps. 

 During the summer the burlaps in the outer towns were 

 visited daily, and the trees were occasionally examined, 

 both by the regular men and by special inspectors. By 

 this means the moth was almost completely eradicated 

 from such towns, and in some of these towns no eggs were 

 found during the autumn. Owing to the insufficiency of the 

 appropriation and the consequent lack of men, the burlaps 

 in the central towns were not as often visited. As the effec- 

 tiveness of this method depends on daily visits to the bands, 

 the results here were not as satisfactory as in the outer towns, 

 but the moths were held in check and somewhat reduced in 

 numbers. 



During the summer an experiment in trapping the male 

 moths was tried, with a view of determining whether the 

 number of fertile eggs would be decreased thereby. Experi- 

 ments with insecticides during the season proved the useful- 

 ness of a new insecticide, — arsenate of lead. Raupenleim 

 was used to a considerable extent in 1893, as it was during 

 1892, but was not found so effective, perhaps by reason of 

 its inferior quality. 



In May the committee voted to request Professor Fernald 

 to invite six of the most prominent entomologists in the ad- 

 joining States to visit the infested region and critically 

 examine the field and office work, and report the results of 

 their observations. Prof. Clarence M. Weed, D.Sc, of the 

 New Hampshire State College, Dr. A. S. Packard of Brown 

 University, Dr. J. A. Lintner, State entomologist of New 

 York, Professor John B. Smith of Rutgers College, State 

 entomologist of New Jersey, and Dr. H. T. Fernald, profes- 

 sor of zoology at the Pennsylvania State College, visited the 

 territory in the summer, examined and criticised the work, 

 and reported upon it. Their reports will be found in A[)- 

 pendix D. The recommendations of these entomologists 

 were carefully considered by Professor Fernald and the 

 director, who reported to the committee that the suggestions 

 made should be carried out as far as practicable.
