Mosquito Crusaders Explain Method of Stalking and, Stifling Mosquitoes on Pane or Wall by Gas Attack

Three months ago the Bureau of Public Health of the Department of the Interior sent out an appeal from Washington for bedbugs, to be used for experimental purposes, and offered a remuneration of five cents per specimen to any citizen who should send one or more of the insects to the department's laboratories.

A similar appeal for sample mosquitoes has been sent out recently by the Anti-Mosquito Association of, Massachusetts, Inc., whose president is Professor George C. Whipple, professor of sanitary engineering at the Harvard engineering school.

The association's appeal begins by declaring that "the several common kinds of annoying mosquitoes have different habits and each may be most effectively dealt with by some particular method." It then offers the services of the association's sanitary experts in identifying the various types for anyone who forwards specimen mosquitoes to their laboratory.

In explaining how these specimens may best be caught, the bulletin declares, "The audit winged biting mosquitoes, may be collected most, conveniently when they have some to rest upon the surface of a window pane or wall. Take a widemouthed bottle and place in it a tuft of cotton saturated with a small amount of "Carbona" cleaning fluid. Place the bottle quickly over the mosquito which will be soon overcome by the fumes. Then transfer it to a small pill box-between two layers of cotton." A pill box with several specimens may then be sent by mail without fear of injury to the mosquitoes.

All specimens of local mosquitoes will be received by Professor Whipple in his office at Pierce Hall.
