S. W. Simmons, of the Washington Office, has devised a food which alone 
will effectively retard growth of maggots while they are in the mails. 
It is very simple and inexpensive, consisting of equal parts of whole 
sweet milk and water with the addition of 13 “percent SCO", .cnis 2Ooe 
permits long-distance shipments of maggots without any ill effects. 
W. G. Bruce of the Ames, Iowa, field laboratory, in cooperation 
with the Department of Veterinary Medicine at Iowa State Collere, is 
making, some preliminary trials of the use of maggots in fistulas and 
other wounds in horses 
Grapping of screw worm flies.--E. W. Laake, Dallas, Texas, states 
that the population ef ail species of flies in the tranped areas has 
been reduced by about 63 percent, as compared with tle pepulation in 
nontrapped sections. From March 1 to October 28 a total of 30,930 
quarts of flies were taken from 673 traps. 
A pene i Civil Works project for pest mosquito control in 36 
States and employing about 25,000 men-was be;un tue latter part of No- 
vember. The most extensive rie will be done along the Atlantic and 
Gulf coasts end will include the draining of considerebie areas of 
salt marshlauds in which mosquitoes breed in enormous numbers. In 
most of the states the State entomologists are acting as Federal agents. 
A Federal Civil Works project for the control of the American dog tick 
(Dermacentor variabilis Say), which transmits Rocky Mountain spotted 
fever, has also been instituted. This provides for work in the States 
Of Virginia, Maryland, Delaware, and the District of Columoia. The 
plan includes the cleaning up of woodlands and the eradication of mice 
@ua Other rodents that are hosts of ticks. The Division of Insects 
Affecting Man and Animals is responsible for the senerai direction and 
Supervision ef these projects. 

HOUSSHOLD AND STORED FRODUCT INSECTS 
W. D. Reed, of the cured tobacco insect laboratory at Richnond, 
Va., who last summer made a study of insect pests of tobacco at var- 
ious tobacco manipulation and storage points in, the Bastera Mediter-— 
ranean area, particularly in Greece and Turkey, aud in the warehouses 
of London, returned to Washington late in November anc is preparing 
a report of his observations. It is hoped Sab contacts established 
through the courtesy of His Excellency Ali Rana Bey, Minister of Cus- 
toms and Monopolies, Turkey, and Hon. Gean G. Theotoki, Minister of 
Greece, will result in fewer insects in tobacco imported into this 
country, a source of loss to American tobecco manufacturers. It is 
eidevod that the conferences held in London with officials of the In- 
perial Collere of Science and Technology and of the Port. of London 
Authority, as well as with various tobacco establishments, will result 
in increased facilities at London for handling American tobacco show- 
ing infestations by common tobacco pests.
