Accidents are common in every large port, but the peculiar construction of the New York ferry houses renders the number of cases of drowning doubly great. In order to guard against this, and to afford timely assistance to persons in danger of drowning, "rescue stations" have been established along the water front of the city. There is one at each ferry house, and the others are located at the points where accidents are most likely to occur. These stations are each provided with a ladder of sufficient length to reach from the pier to the water at low tide, with hooks at one end, by means of which it is attached firmly to the pier; a boat hook fastened to a long pole; a life preserver or float, and a coil of rope. These are merely deposited in a conspicuous place. In case of accident any one may use them for the purpose of rescuing a person in danger of drowning, but at other times it is punishable by law to interfere with them, or to remove them. The station is in charge of the policeman attached to the "beat" in which it is located, and he has the exclusive right in the absence of one of his superior officers to direct all proceedings. At the same time he is required to comply strictly with the law regulating such service on his part, and to render every assistance in his power. The law for the government of those using the "rescue apparatus" is posted conspicuously by the side of the implements, as are also concise and simple directions as to the best method of attempting to resuscitate drowned persons. These stations have been of the greatest service since their establishment, and reflect the highest credit on those who originated and introduced them. CHAPTER LVII. QUACK DOCTORS. Many years ago a sharp-witted scamp appeared in one of the European countries, and offered for sale a pill, which he declared to be a sure protection _against earthquakes_. Absurd as was the assertion, he sold large quantities of his nostrum, and grew rich on the proceeds. The credulity which enriched this man, is still a marked characteristic of the human race, and often strikingly exhibits itself in this country. The quack doctors, or medical impostors, to whom we shall devote this chapter, live upon it and do all in their power to encourage it.
