Malaria Control Health Worker (1920s)
This 1920s photograph showed a malaria control health worker gripping a hand-held augur, and next to him, atop a tree stump were a number of sticks of dynamite and detonator. Stumps such as the one to his right, were removed using these explosives in order to make way for the creation of drainage ditches that would subsequently act as routes for the drainage of standing water.
The procedure is to drill a hole in a tree stump with the hand-held augur, then place a number of sticks of dynamite in the hole. The dynamite is then detonated, thereby, destroying the stump. Once the stumps are cleared, the drainage ditch can be dug. Drainage ditches assist in the removal of standing water in which the larvae of malaria vectors such as Anopheles mosquitos may reside.
