Garbage should be removed daily from all places where it accumulatesin large quantities, and two or three times a week from privateresidences. All garbage awaiting removal should be kept in closedcans. Garbage must not bc dumped within the city limits unless it isdumped on in_cinerators where fires will soon consume it.

Tin cans, bottles, and receptacles which will hold water, mustnot be allowed to accumulate in back yards, alleys or vacant lots, normay they be dumped within the city limits or near residential sectionsin the suburbs, because they furnish excellent breeding quarters formosquitoes.7.

Especial attention should be given to the prevention of insectbreeding on such premises.INDUSTRIAL SANITATIONMany industries have important entomological sanitary problems inthe preservE4tion of their products from insect contamination and in thel'Worts to conform to sanitary regulations. There are many times whenthey \vould be able to use the services of a consulting sCJ.nitary entomologistto advantage.The keynote of industry today is the prevention or utilization ofwaste. Insect depredations On food products cause waste because thepublicdoes not want polluted food, and because sanitary inspectors arebecoming more and more alive to the menace to health from insect pollutedfoods.It is not generally understood that the presence of weevils and wormsin cereal foods may do more than destroy the food.
