Text from William Wade

On the right hand, five miles from the City Hall, and on York Island, is the scattered village of Bloomingdale, presenting to the curious eye a pleasant aspect in the Orphan Asylum, with its green lawn extending to the water's edge, and surrounded by a grove. Three miles further up the island-eight miles from the City Hall-is the Lunatic Asylum, a stately pile, standing on elevated ground. Half a mile north of the Asylum, is the village of Manhattanville, having a convenient landing and wharf, and containing about eighty houses, with five hundred inhabitants. A mile and a half east of this is the village of Harlem.
The next object of notice after passing Manhattanville, and the highest point on New York Island is Fort Washington, two hundred and thirty-eight feet above the river.
