Morris, Gouverneur; De Witt, Simeon; and Rutherford, John [sic] (March 1811) "Remarks of the Commissioners for Laying Out Streets and Roads in the City of New York, Under the Act of April 3, 1807", Cornell University Library. Accessed June 27, 2016. "These are one hundred feet wide, and such of them as can be extended as far north as the village of Harlem are numbered (beginning with the most eastern, which passes from the west of Bellevue Hospital to the east of Harlem Church) 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. This last runs from the wharf at Manhattanville nearly along the shore of the Hudson river, in which it is finally lost, as appears by the map. The avenues to the eastward of number one are marked A, B, C, and D."
