6 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 195 3 
Invented and patented for public use 12 years ago by Bureau scien- 
tists, the aerosol, or mist-spray, dispenser lias become practically the 
basis of a $95 million industry in this country 7 . It is now being used 
for dispensing deodorants, shaving cream, whipped cream, and numer- 
ous other materials. 
Expansion of insecticide-manufacturing facilities in 1951 and 1952 
resulted in plent iful supplies of the new synthetic organic insecticides 
during the 1952 crop season. Drought over much of the country in 
1952 resulted in a lower consumption of insecticides than in previous 
years. Consequently there was a large carryover of many of the im- 
portant insecticides, which should assure an ample supply for use 
throughout 1953. It has been estimated by a national trade associa- 
tion that pesticide manufacturers are now producing more than 1 
billion pounds of finished insecticides per year with a value of more 
than $250 million. 
Nineteen entomologists were engaged in the Point IV technical- 
assistance program at the end of the fiscal year. These men were sta- 
tioned in 12 countries in the Eastern and Western Hemispheres. The 
major Point IV activity in which this Bureau collaborated was the 
Regional Locust Control Program, conducted in cooperation with the 
Foreign Agricultural Service of the United States Department of 
Agriculture and the Foreign Operations Administration in Iran, Pak- 
istan, India, Iraq, Jordan, and Ethiopia. xVssistance was rendered in 
these countries through demonstration of aerial spraying techniques 
and training of pilots, mechanics, and locust-control personnel. Bu- 
reau services provided to Point IV entomologists included insect iden- 
tification, program planning, general advice, and guidance on ento- 
mological problems in foreign countries. 
Numerous phases of the Bureau's activities were reviewed by Bureau 
specialists with 827 foreign visitors who were in the United States 
during 1952 under the sponsorship of the Department's Foreign Agri- 
cultural Service. An Agricultural Research Administration consult- 
ant on international programs accompanied these visitors and assisted 
them in making the appropriate contacts.

and Ralph A. Sheals, assistant chief in charge of administration, left
