Soon Staten Island is passed, and we see the white lighthouse standing out in the water, which marks the entrance to the Kill Van Kull, or Staten Island Sound; and, far to the westward, we can faintly discern the shipping at Elizabethport. We are now fairly in the harbor of New York, with the great city directly in front of us, Brooklyn on our right, and Jersey City on our left. To the northward, the line of the Hudson melts away in the distant blue sky, and to the right the East River is lost in the shipping and houses of the two cities it separates. The scene is gay and brilliant. The breeze is fresh and delightful; the sky as clear and blue as that of Italy, and the bay as bright and beautiful as that of Naples, and even more majestic. As far as the eye can reach on either side of the Hudson extend the long lines of shipping, while the East River is a perfect forest of masts. Here are steamboats and steamships, sailing vessels, barges, and canal boats--every sort of craft known to navigation. The harbor is gay with the flags of all nations. Dozens of ferry boats are crossing and recrossing from New York to the opposite shores. Ships are constantly entering and leaving port, and the whole scene bears the impress of the energy and activity that have made New York the metropolis of America. At night the scene is indescribably beautiful. The myriad stars in the sky above are reflected in the dark bosom of the harbor. The dim outlines of the shores are made more distinct by the countless rows of lights that line them, and the many colored lamps of the ferry-boats, as they dart back and forth over the waters, give to the scene a sort of gala appearance. There are several islands in the harbor, which have been entirely given up to the United States Government for military purposes. The largest of these is Governor's Island, formerly the property of the redoubtable Wouter Van Twiller, and still called after him. It lies midway between New York and Brooklyn, at the mouth of the East River. It embraces an area of seventy-two acres, and is one of the principal military posts in the harbor. Fort Columbus, in the centre of the island, is the principal work. Castle William, on the west end, is a semi-circular work, with three tiers of guns. Two strong batteries defend the passage known as Buttermilk Channel, between the island and Brooklyn. In the early days of the Dutch colony, this passage could be forded by cattle; now it is passable by ships of war. These works are armed with upwards of 200 heavy guns. Ellis Island, 2050 yards southwest from the Battery Light-House, contains Fort Gibson, mounting about twenty guns. Bedloe's Island, 2950 yards southwest of the Battery Light-House, contains Fort Wood, which is armed with eighty guns. The best point from which to view the Inner Bay is the Battery Park, from the sea-wall of which an uninterrupted view of the bay and both rivers may be obtained. III. THE CITY GOVERNMENT.
