On the top of nearly every house in the section where _artesian_ water is used, there is a _tank_ to receive water for various purposes about each dwelling; much of this is employed for drinking and culinary uses. Without any attempt at a sensation, we pronounce this box or _tank_ a _death trap!_ There is not a clean one in this whole great city, that has an outside exposure, and 9 out of every 10 are reeking with filth. Having had occasion to investigate several I am convinced that they average alike. If so, there are at least 500 tons of concentrated filth playing the part of filters in the tanks of this city alone at this writing! And there is every reason to believe that this city is as clean as the average. Provided this is so, there is enough of such refuse in the United States to dam the Mississippi River many times and build a levee across Lake Erie. Health officers may keep their own tanks clean in the future, but if individuals desire health and abolition of the need of Health Boards, let them keep their own tanks, back yards, streets, and pavements neat. Municipal corporations should prevent by _law_ the throwing of any kind of rubbish into the streets, and make it a misdemeanor for the proprietors allowing any of their mercantile houses, work-shops, or residences to be found filthy, and there are thousands of them in this city. To avoid accidents, every man, woman, and child should be compelled to pass to their right on the street. Every person in every city not having a legitimate vocation in the eyes of the law, nor an income from property or money in the bank, should, if criminally inclined, be sent to the House of Correction. If poor and willing to work, they ought to be put to work in the public streets and in the parks, to beautify them, for the benefit of the frugal classes. No begging should be allowed, under penalty of imprisonment. That a city may escape being overrun by country tramps, their entrance should be quarantined.
