The Seamen's Retreat is also on Staten Island, a mile below the quarantine ground, built upon a natural terrace, about one hundred feet above the water, and fronting the Narrows. The location is one of exceeding beauty, being surrounded by sylvan scenery of unsurpassed loveliness, and commanding a prospect of great extent, which embraces the city, the shore of New Jersey, the Palisades, Long Island, and the highlands of Neversink and Sandy Hook. The Hospital is a noble building, constructed of rough granite, three stories high, and surrounded by piazzas, upon which the patients may inhale the pure air, and beguile their confinement by watching the ever-changing panorama presented by the bay, with its countless ships and steamers. The Retreat is intended solely for sick but not disabled seamen. It is supported by a fund derived from a state capitation tax, levied upon all seamen sailing from this port, and is the only establishment of the kind in the United States, or, we believe, in the world. Seamen are the only class who are compelled by the law of the state to contribute to a fund to form a provision for them in case of sickness. The income for the support of the Retreat is ample, and the most liberal provision is allowed for all whose necessities compel them to seek admission. On the grounds are houses for the residence of the physician and keeper. [Illustration: SAILOR'S SNUG HARBOR.] This noble Charity is situated on the north side of Staten Island, about three miles from the Quarantine, and commands a magnificent view, with the city in the distance. It is surrounded with elegant villas, pretty cottages, and well cultivated farms, and is in the midst of the loveliest rural scenery that the neighborhood of New-York can boast of. The grounds belonging to the institution comprise about one hundred and sixty acres of land, which is inclosed by a handsome iron fence that cost, a few years since, thirty-five thousand dollars. The principal building is constructed of brick and faced with white marble, with a marble portico. The corner-stone was laid in 1831, and the institution opened for the reception of its inmates in 1833. The centre building is sixty-five by one hundred feet, with two wings fifty-one by one hundred feet, connected with the main building by corridors. There are two handsome houses for the residences of the governor of the institution, and the physician, and numerous offices and outhouses.
