the equipment. Extreme care should be exercised to keep all joints of such 
apparatus tight and replace any defective parts to prevent accident. The 
operator should avoid getting any liquid methyl bromide on his clothing or his

(2) Carbon disulphide. 
(i) The vapor of carbon disulphide is inflammable and explosive. At a 
temperature of 297° F. it may take fire spontaneously and in the presence of 
certain metals, particularly copper, it may ignite at considerably lower tempera- 
tures. It must be kept away from fire, and from hot objects such as electric 
light bulbs, unprotected brush-type motors, steam pipes, etc. Lighted cigars, 
cigarettes, or pipes must never be brought near carbon disulphide. 
(ii) Carbon disulphide is a blood poison, but poisoning by this chemical is 
rare. Exposure to the vapor may cause giddiness and headache. When these 
symptoms develop, the individual should get into the open air.

MISCELLANEOUS ITEMS 
WAKELAND TO HEAD DIVISION OF GRASSHOPPER CONTROL 
[Press notice] 
February 4, 1942. 
The Department of Agriculture today announced creation of the Division of 
Grasshopper Control within the Bureau of Entomology and Plant Quarantine 
to supervise cooperative programs with the States in control of grasshoppers, 
Mormon crickets, and chinch bugs. Leader of the new division is Dr. Claude 
Wakeland, said Dr. P. N. Annand, Chief of the Bureau. 
While programs of control for chinch bugs, Mormon crickets, and grasshoppers 
have been in operation for a number of years, this is the first time that the work 
has been unified under one division. Headquarters for this division will remain 
in Denver, Colo., where they have been since 1940. Doctor Wakeland, who has 
had field direction of the cooperative programs of grasshopper and Mormon 
cricket control since 1939, was born August 2, 1888, at LaJara, Colo. He at- 
tended public school in Denver, graduated from Colorado State College with a 
B. S. degree in 1914, received an M. S. from the same institution in 1924, and 
in 1934 received a Ph. D. from Ohio State University. 
He started active work in entomology with the Colorado Agricultural Experi- 
ment Station. In 1920 he was appointed extension entomologist for the Uni- 
versity of Idaho, and 1928 was made head of the Department of Entomology at 
that University. 
In 1938 he was appointed to the Bureau of Entomology and Plant Quarantine 
as project leader on Mormon cricket control with headquarters in Salt Lake 
City, and the following year was made field director of the combined grasshopper 
rind Mormon cricket control programs.
