Of measures mdirectly affecting the prevalence of Anopheles, the most important are " drainage " and " agriculture." The dramage of marshes, lakes, etc. has long been known to have a favou...rable effect upon malaria. Agricultural operation, by which waste lands are reduced to the condition of tilled fields, is another general measure having a very definite influence upon malaria. Both these measures, though they do not aim directly at mosquito reduction, bring about this result indirectly by lowering the level of the subsoil water, lessening humidity and so forth.
