The Halve Maen remains at anchor somewhere near the modern site of the Port of Albany. Captain's Hudson's first mate sets out with four crewmen in the ship's small boat, or sloep, to continue exploring another six miles upriver. At dusk, they return and report that the river continues to grow more shallow and narrow.
On September 20th, 1609:
The twentieth, in the morning was faire weather. Our Masters Mate with foure men more went vp with our Boat to sound the Riuer, and found two leagues aboue vs but two fathomes water, and the channell very narrow; and aboue that place seuen or eight fathomes. Toward night they returned: and we rode still all night.
