The people of the State have a vital interest in the public health of our city. Connected as it is by means of rapid inter-communication with all parts of the country, there is every facility offered for the wide diffusion of the seeds of contagion. It is estimated by accurate statisticians that no less than 250,000 persons pass in and out of New York daily over the ferries and railroads. It could not fail to happen that if any contagious disease prevailed in this city, it would be carried into the country and widely disseminated. And such is now a matter of daily occurrence. There is no doubt that nearly all the epidemics of smallpox in country towns, and much of the typhus and similar diseases, have their origin in New York. I have in my hand letters from all parts of the State confirming this statement. They strikingly illustrate the want of a good sanitary police in New York, and the power of a great commercial centre to scatter disease broadcast over the country. A few of these cases will abundantly illustrate the point: Dr. J. S. Sprague, of Cooperstown, Otsego County, reports the occurrence of twenty-six cases of smallpox in that town, communicated by one person in October, 1860, who took the disease at a hotel in our city, in which a person with the disease had recently died. He was a merchant, and came to the city on business. Dr. C. C. F. Gay, of Buffalo, reports the case of a female, who arrived from New York in November, 1860, and was removed from the cars of the Erie Railroad to the State Line Road, and proceeded westward. As was afterward ascertained, she had smallpox, and communicated the disease at Columbus, Ohio, where there were three deaths produced by it. Four deaths were directly traceable to this exposure, viz.: three milkmen and one baggage man, all of whom came in contact with the sick woman. W. T. Babbitt mentions the case of a young man who took the disease in this city at a hotel where it was prevailing, at which he stopped while on a visit here, in whom the disease appeared after his return to Olean, in Cattaraugus County. Dr. M. Jarvis, of Canestota, Madison County, relates the case of a man who visited this city with horses for sale, and was attacked with symptoms of smallpox some ten days after his return to Smithfield, in that county, who communicated the disease to his family, from whom it spread to others in that and, also, in a neighboring town.
