C. H. HADLEY APPOINTED TO TAKE CHARGE OF THE JAPANESE-BEETLE LABORATORY 
The research work on the Japanese beetle and Asiatic beetle, 
with headquarters at Moorestown, N. J., has been put in charge of Charles 
H. Hadley, who succeeds Loren B. Smith, resigned. Mr. Hadley's appoint-— 
ment was made effective December 16, 1930. 
In 1919, soon after the Japanese beetle was discovered in the 
United States, Mr. Hadley was put in charge of both the research on 
this insect and the quarantine operations against it, and continued 
in this capacity until 1923. In the latter year he resigned to be- 
come Director of the Bureau of Plant Industry of the State Department 
of Agriculture of Pennsylvania, his native State, and there had charge 
of its interest in the cooperative work with the Japanese beetle. In 
1927 he relinquished that position to become an agent of the Bureau 
of Entomology, with duties relating to the emergency campaign against 
the European corn borer. In 1928, after the reorganization of the plant— 
quarantine work of the Department of Agriculture, he was transferred 
to the Plant Quarantine and Control Administration and placed in charge 
of the quarantine work against the Japanese beetle, and served contin- 
uously in that capacity until his present appointment. He has therefore 
been in immediate contact with the campaign against the Japanese beetle 
‘almost continuously since that insect became prominent as a pest, and 
brings to his present duties a very unusual background of experience.
