As we have said, the greater number of the emigrants arriving here have money when they come. Others, who have been able to raise only enough to reach this, to them, "land of promise," or who have been swindled out of their funds by sharpers in European ports, arrive here in the most destitute condition. These are a burden to the city and, State at first, and are at once sent to the Emigrant Refuge and Hospital. EMIGRANT REFUGE AND HOSPITAL. This establishment is located on Ward's Island, in the Harlem River, and consists of several large buildings for hospitals, nurseries, and other purposes. It has a farm of one hundred and six acres attached to it. The destitute emigrants are sent to this establishment, as soon as their condition is ascertained, and cared for until they either obtain employment, or are provided for by their friends in this country, or are sent to their original destinations in the West at the expense of the Commissioners. Medical attendance is provided at the Landing Depot, and is free to all needing it. Serious cases are sent to the hospital on Ward's Island, where good medical skill and attendance are furnished. The number of emigrants at the Refuge sometimes amounts to several hundred of all nationalities. The Irish and German elements predominate, and these being bitterly hostile to each other, the authorities are frequently compelled to adopt severe measures to prevent an open collision between them. In the winter of 1867-68, the Irish and German residents on the island came to blows, and a bloody riot immediately began between them, which was only quelled by the prompt arrival of a strong force of the City Police. PERILS OF EMIGRANTS. The Commissioners adopt every means in their power to prevent the inmates of the Landing Depot from falling into the hands of sharpers. Each emigrant in passing out of the enclosure for any purpose is required to apply for a permit, without which he cannot return, and no one is allowed, by the policeman on duty at the gate, to enter without permission from the proper authorities. In this way sharpers and swindlers are kept out of the enclosure, inside of which the emigrant is perfectly safe; and when he ventures out he is warned of the dangers he will have to encounter the moment he passes the gateway. The majority of the emigrants are unable to speak our language, and all are ignorant of the country, its laws, and customs. This makes them an easy prey to the villains who throng the Battery in wait for them.
