The State of Massachusetts attempted to exterminate the gipsy moth 
and failed and yet this insect has been eradicated in other sections of 
the county where there was considerable infested territory of a some¬ 
what difficult nature. We are inclined to believe that the effort in 
Massachusetts was possible though not practicable. It might have 
been entirely feasible for the general government. Attempts are now 
being made to exterminate or greatly restrict the spread of free flying 
insects. These efforts have not progressed to the point where success 
is a foregone conclusion. It is characteristic of the times that pro¬ 
positions of this nature are being received with an optimism unknown in 
the earlier days. There are a number of cases where extermination, 
even were most drastic measures necessary, would have been cheaper 
than the cost of subsequent control. Should extermination be suc¬ 
cessful, the possibility of reestablishment in a similar manner must not 
be overlooked. It is an excellent time to forecast probabilities and 
determine the most promising lines of effort. 
Obituary 
STUART C. VINAL 
Mr. Stuart C. Yinal, assistant entomologist of the Massachusetts 
Experiment Station, died at Arlington, Mass., September 26, as the 
result of typhoid pneumonia following influenza. Mr. Vinal gradu¬ 
ated at the Massachusetts Agricultural College in 1915 and continued 
his entomological work there for an advanced degree, receiving his 
M. S. in 1917. In September of that year he was appointed assistant 
entomologist at the Massachusetts Experiment Station, after which 
his time was mainly devoted to investigations on market garden insects. 
He was a young man of unusual ability and the work he accomplished 
was excellent in its quality. His three published papers are “Notes 
on the Life-History of Marmara elotella Busck,” Journ. Econ. Ent., 
10: 388; “The Greenhouse Red Spider Attacking Cucumbers and 
Methods for its Control, ” Bulletin No. 179, Mass. Exp. Sta., and 
“The European Corn Borer, Pyrausta nubilalis Hiibner,” Bulletin No. 
178, Mass. Exp. Sta. Another paper, “A Morphological Study on the 
Respiratory System of the Carolina Locust” is awaiting publication. 
All of his time during the past year has been devoted to an investiga¬ 
tion of the life-history of the European corn borer, and he had collected 
material on this for another bulletin to be published this fall. The 
material thus obtained will probably be combined with that collected 
by workers in the Bureau of Entomology, with whom he was cooperat¬ 
ing at the time of his death.
