 The stream rapidly descends through the narrow defiles into Warren County, where it receives from the east the outlet of Schroon Lake, and the Sacandaga River from the west.Below the mouth of the latter the river turns eastward, and breaks through the barrier of the Luzerne Mountains in a series of rapids and falls.At Fort Edward it again turns south and flows with a rapid current, frequently interrupted by falls, to Troy, from the ocean.
