VOL. XLV.-NO. II. Steilacoom harbor,.. In passing from New-York to an eastern port, the first great change in the tides and tidal currents is between the East River and Long Island Sound; the difference between Governor's Island and Negro Point on Ward's Island, at the eastern entrance to Hell Gate, is two hours and forty-five minutes. Between this point and Throg's Point the change is small. The mariner is now in the full tide of the Sound, and between Throg's Point and Fisher's Island there is a difference of time of but two hours and twenty minutes, the greatest part of which is at the head of the Sound and at its entrance—that is, near Throg's Point and Fisher's Island. From off New-London to off Sand's Point the difference is but one hour and forty minutes; so that if the mariner, instead of remaining at Throg's Point, passes onward to Fisher's Island, he would lose but half a tide in the whole passage. 1 The depth in channel way varies between 6 and 8% fathoms. Two bars, each a quarter of a mile, have a less depth than 18 feet. A small shoal, with 12 feet, lies in the middle of the kill, opposite the wharf at Blazing Star; and another, with 10 feet, a quarter of a mile to the northward; but deeper water is found on east side of both. A shoal, of 4 feet, obstructs the eastern channel, half way between Chelsea and its junction with the main channel. 5 Channel very narrow in the vicinity of Black Beacon. • From Bergen Point light, half way to Newark Bay lighthouse, 17 feet may be carried. In a straight line. A shoal of 21.5 feet occurs about a mile below Sing Sing. • Soundings varying between 10 and 15 fathoms. 12 SHIP-BUILDING AND TONNAGE OF NEW-YORK.
