Mr. John N. Summers, who has been traveling in Europe for several. 
ths studying gipsy moth and trown-tail moth conditicns reached New 
On September 12. Mr. Summers’ return to Melrose Highlands, Mass., 
‘Omewhat delayed on account of the chaotic condition existing in Eu- 
pe caused by the war. . 
Mr. Leonard S. McLaine, Assistant to Dr. C. Gordon Hewitt, Dominion 
Mtomologist of Canada, nas recently returned to Canada. Mr. Mclaine has 
Bn Stationea at the Gypsy Moth Laboratory, Melrose Highlands, Mass., 
Mi has been engaged in collecting parasites of the gipsy moth and the 
Own-tail moth for shipment to New Brunswick and Nova Scotia where an 
ttempt wiil be made to colonize these species. 
Mr. J. C. Nellis, Forest Examiner, Forest Service, Washington, D. C., 
f August 17 and 18 made a preliminary investigation into the possibili- 
les of the utilization of the products of sylvicultural thinnings in the 
Swn of Winchendon, Mass. The problem of disposing of the large amount 
f low-grade meterial resulting from the removal of trees susceptible to 
ipsy moth attack is a serious one, and one that must be fully considered 
2 connection with the problem of converting stands of species susceptible 
psy moth attack into stands of less susceptible species, a problem 
lon whicn the Bureau of Entomology and the Forest Service have been work— . 
ig together for some time. , 
‘A report has been received from Mr. N. E. Shaw, Chief Inspector, De- 
irtment of Agriculture, Columbus, Ohio, that several gipsy moth ege-clus— 
Brs have been found on a shipment of stone received in Ohio from Massa-— 
stts. This occurrence emphasizes the necessity of action being taken 
®) event the distribution of egg-clusters into uninfested territory on 
lipments not subject to inspection by the Federal Horticultural Board. 
In connection with the work on the wilt disease of the gipsy moth,,. 
lich is being carried on by Messrs. R. W. Glaser and J. W. Chapman, at 
ie Bussey Institution, a number of quite similar polyhedral diseases have 
sen found in native caterpillars. In case caterpillars are found which 
ve apparently died from any bacterial disease in any part of the coun- 
‘y, or at any of the field stations of the Bureau, a small number of 
pecimens are very much desired for study. These can be shipped in a dary 
mdition, but it will facilitate the work very much if a note accompanies 
le seniing stating where the caterpillars were found and giving any other 
formation about the species concerned.
