Caption:
Depicted in this historic image was a public health technician, who was standing before a group of fellow public health workers, as he instructed the men, in the proper use of a mosquito control insecticide dispersal machine, which dispensed a cloud in insecticidal chemicals into a mosquito populated environment. The unit was self-contained, producing its own air jet, by way of a motorized air pump that was strapped to the speaker’s back.
