Dr. Charles H. Hadley Heads Pennsylvania Bureau of Plant Industry 
Charles II. Hadley, recently named by Secretary of 
Agriculture Frank P. Willits as the new director of the 
Pennsylvania Bureau of Plant Industry, took immedi¬ 
ate charge of the work of the bureau on the day of his 
appointment, July 23, 1923. 
Director Hadley is probably most widely known to ag¬ 
riculturists in Pennsylvania and in other parts of the 
country through his endeavors during the past three 
years as the Federal Entomologist in charge of all field 
operations of the joint Japanese beetle project in south¬ 
eastern Pennsylvania and in New Jersey. Entering the 
Federal service in April, 1919, as a plant quarantine in¬ 
spector at Riverton, N. J., laboratory, later put in charge 
of the control work with 25 to 30 men under his direction 
and in October, 1920, placed in complete charge of the 
project, his record of achievement in entomological work 
has been notable. 
By training and extensive experience with insect con¬ 
trol problems in New York, New Hampshire, New Jersey 
and Pennsylvania, Professor Hadley is ideally fitted to 
head the State corps of experts whose duty it is to pro¬ 
tect Keystone State farming against plant disease and in¬ 
sect invasions. His knowledge of Pennsylvania agricul¬ 
tural conditions gained in three years spent in the agri¬ 
cultural extension service at the Pennsylvania State Col¬ 
lege will also stand him in good stead in his new posi¬ 
tion. 
His early education was obtained in the Manual Train¬ 
ing High School and the Polytechnic Preparatory School 
in Brooklyn, N. Y. In the fall of 1908, he entered Yale 
University and two years later transferred to the New 
Hampshire College of Agriculture and Mechanic Arts, 
receiving the degree of bachelor of science in 1912. 
While a student at the New Hampshire State College 
he assisted in the insectary and laboratory and also en¬ 
gaged in experimental work in the field. For three years 
after graduation he held an assistantship in entomology 
in the college experiment station and in 1915 he went to 
Cornell University to pursue a year of study in advanced 
entomological subjects. 
At Cornell, as a part-time member of the experiment 
station stall', he investigated outbreaks of grasshoppers 
and other insects and devoted much of his time to insects 
affecting clover and alfalfa. 
From 1916 to 1919, Professor Hadley availed himself 
of an opportunity to become thoroughly acquainted with 
conditions in Pennsylvania farming. It was during this 
period that he engaged in agricultural extension work 
as the only trained entomologist at that time in the em¬ 
ploy of the Pennsylvania State College. In the last of 
the three years and just prior to his entrance into Federal 
activities, he was placed at the head of entomological re¬ 
search work at State College and in this capacity he es¬ 
tablished and directed three field stations, at Bustleton, 
Erie and Arendtsville, for the purpose of studying insects 
injurious to Pennsylvania crops and devising methods 
for their control. 
He is a member of the American Association for the 
Advancement of Science and has been a member of the 
American Association of Economic Entomologists since 
1912. Other affiliations include Alpha Zeta, honorary ag¬ 
ricultural society, and Sigma Xi, honorary scientific so¬ 
ciety. Among his most recent publications are: “The 
Japanese Beetle” (New Jersey Station circular), and 
“The Clover Leaf Weevil” (Cornell Experiment Station 
bulletin). Other scientific contributions include: “The 
Lesser Migratory Locust (Cornell), “Potato Insects” 
(Pennsylvania), “Arsenical Besidues” (New Hamp¬ 
shire), “The Rhododendron Lace Bug,” “The 17-Year Lo¬ 
cust in New York,” and “The Japanese Beetle Quaran¬ 
tine,” in various issues of the Journal of Economic En¬ 
tomology. 
In the four years that he has spent in the Japanese 
beetle area, Professor Hadley has adequately displayed 
his ability to conduct a fight against a dangerous insect 
foe. The Japanese beetle is admittedly one of the worst 
insect pests that has ever invaded this country. No con¬ 
trol measures or exterminating agencies commonly used 
with success against other insects have been of any 
avail. The beetle has safely withstood all of the most 
common, practical and economical means of control at 
present known to the scientist. The fact that progress 
is gradually being made in the government’s investiga¬ 
tions, however, casts a ray of hope on the situation. 
It is therefore encouraging to those interested in the 
successful culmination of the Jap beetle light that an 
agreement has been made between the Pennsylvania and 
the United States governments whereby Director Hadley 
will continue to oversee the general operations of the co¬ 
operative project during the next few months, while also 
giving his attention to the new duties in Pennsylvania. 
Part of his time will be given to the Federal work in 
which he has been engaged and part to the duties of the 
Pennsylvania directorship. In his absence on Federal 
duty, general supervision of the State work will be vest¬ 
ed in Deputy Director Walter A. McCubbin. 
Under this agreement all of the major activities of the 
Pennsylvania Bureau of Plant Industry will be conduct-
