ings and sheds, which were filthy and in some cases not sewered, the appliances used being inadequate and primitive, and the meth- ods, especially from their publicity, indecent and demoralizing ; that cattle were driven through the public streets in populous quarters with great danger to life ; that the plumbing and drain- age of dwellings, private as well as tenement houses, were ex- tremely defective, allowing sewer-gas to freely escape into the apartments ; that offensive odors from gas, fat-melting, and other manufacturing establishments were not uncommon ; that stables were generally without proper drainage and very offensive ; and that stable manure was allowed to accumulate, was removed irregularly and in an offensive manner, and was stored for sale in the vicinity of dwellings ; and that the removal and disposal of offal, dead animals, and night-soil were conducted in a primitive manner disgraceful to a civilized city. It was also reported that there was no proper supervision and care by public authority of contagious diseases or to prevent their spread ; that there was no public inspection of the food-supply of the city, and especially of milk, meat, and fish ; that there were no regulations or inspec- tions for the purpose of insuring to new buildings proper light, ventilation, and drainage, or to secure the correction of defects and the proper cleanliness of buildings already occupied as human habitations ; in short, that the public health received no intelli- gent consideration from the municipal government, and that the demoralization incident to filthy streets and dwellings and to other unsanitary conditions threatened the material prosperity and the moral and social welfare of the city.

The action of the sanitary authori- ties of New York has been conservative and conciliatory, but firmly and steadily progressive. By persuasion and explanation important sanitary changes and improvements have been inaugu- rated, and, when approved by the common sense of the more intel- ligent and public - spirited, have been completed by legal com- pulsion ; sanitary rules and regulations have been constantly enforced by an expert and vigilant corps of educated inspectors ; and thus by a faithful and persistent public service, and without excitement or startling innovations, New York has been gradually relieved of the nuisances which afflicted its people and threatened its prosperity a quarter of a century since. For several years the Croton water supply, so important and essential to the health
