The mosquito breeds in water, and the so-called wigglers found instagnant pools are the young form or larva1. While aquatic in theirmode of life, these larvae are air-breathing, and have to come to thesurface for a supply of air. For this reason they frequently come tothe top, stick out their breathing apparatus, which is a sort of tail-liketuft, and after absorbing the supply of air, disappear in the depths oftheir breeding-pool again. It is for the reason that the larvae are com-pelled to come to the surface to breathe that pouring coal oil over stag-nant pools will keep them down and is the most effective remedy forthis evil. The family Chir-onomidae are the t
