1. Preserve or procure open spaces, sufficient to form recreation grounds for your communities--say an acre for every thousand inhabitants. Regard this to be quite as imperative a necessity as the acquisition of further land to add to the cemeteries in which you inter the bodies of those who have "gone over to the majority." Let the quick share your care and attention on equal terms with the dead in the matter of requisite space and accommodation. 2. Cause your common lodging-houses and your still worse haunts to be under the most vigilant supervision; and that _constantly_, and not fitfully and spasmodically. The more severe and restrictive your regulations are with reference to these matters the better it will be for all decent, quiet citizens. 3. Provide every householder within your jurisdiction with a _filter_, to insure to him and his the opportunity of enjoying water free from organic and other impurities. 4. Furnish him also with two boxes, varying in size according to the dimensions of his domicile: one to form a receptacle for dust, cinders, old rags, broken bottles, and what is generically known as "dry dirt;" and the other for decayed vegetables, the entrails of fish, and that kind of refuse that we rather uneuphoniously call "muck." Such boxes to be taken away once a week and empty ones left in their stead. As a corollary to this, forbid him, under penalties, to continue his present practice of pitching derelicts into the street, as the readiest means of being quit of them; and make him responsible for the cleanliness of his doorsteps and the pavement in front of his dwelling. 5. Send round carts of chloride of lime, at short intervals during warm or "muggy" weather, and direct a bucketful to be delivered to every housewife, to remove stenches from sinks, water-closets, &c. 6. Erect a furnace in some convenient locality, to serve the same purpose as that known as the "Queen's tobacco-pipe" at the London Docks does or did--_i.e._, to reduce to ashes all infected or condemned articles. The foregoing list of recommendations might be extended indefinitely; but perhaps the above will be sufficient to begin with.
