    cases of malaria are occurring close by. Stables and servants’ go-downs are very favourite haunts for adult Anopheles. Now in order to kill mosquitoes wholesale, it is necessary only to destroy their larvae. This is generally a very easy matter, especially in regard to Culex. We have only to go round the premises at least once a week and to empty out oil pots and vessels containing stagnant water, and also to brush out with a broom all puddles containing larva. As the larvae take about a week to mature, this procedure will generally be enough to keep the insects away; but, at the same time, it is necessary to prevent water collecting anywhere near the house. These duties should be attended to by reliable persons, and should not be left to native servants. If mosquitoes are numerous in a house, they will generally be found to be breeding just outside the windows. Hence people can generally keep their houses comparatively free of these pests simply by attending to their own premises. It often happens in towns, however, where houses are crowded together, that a neighbour is so obliging as to breed thousands of mosquitoes daily for the supply of the adjacent dwellings. In such cases a copy of this pamphlet may be sent him, with any remarks which may be considered suitable ; and if he does not attend to these, the local municipality may be referred to.

Prominent citizens should lay the matter strongly before municipalities; and all municipalities should employ at least one special agent for the destruction and prevention of mosquitoes.
