In consequence of a letter received by us the subscribers, members of the secret committee, from the Committee of Safety, dated the day of November instant, when we were at Fort Montgomery fixing the chain across the river, enclosing an extract from a letter of Gen. Schuyler, requesting the Convention to have the river sounded in different places in the Highlands, we have sounded the river, beginning between Verplanck's and Stoney Point, thence northward through the Highlands to Pollapel's island, and find no part of the river in that distance less than eighty feet deep in the main channel, till within a short distance of the island.

From the island to the western shore, found by measurement, the distance to be fifty-three chains; the channel near the middle of the river at that place is about eight chains broad, and fifty feet deep; from the channel the water shoals gradually on both sides to the flats, which are about eight or ten chains broad, reckoning both sides.

This above described place is the only one in our opinion, that it is possible for an obstruction to be made by docking, efectually to impede the navigation of Hudson's river, at any place above the south part of the Highlands.
