At Glens Falls there is a fall of about 50 ft. Below the mouth of the Sacondaga the Hudson turns sharply and flows eastward for about 12 m., passing through the mountains, and leaping over several falls of great height and beauty. In this part of its course the Hudson has many falls and rapids, and receives a number of mountain streams as tributaries, the largest being Indian river, Schroon river and Sacondaga river. per mile in the upper 52 miles, then, from the mouth of North Creek to the mouth of the Sacondaga, at the rate of nearly 14 ft.

This small mountain stream flows irregularly southward with a fall of 64 ft. There are a number of small mountain streams which contribute to the headwater supply, any one of which might be considered the main stream but assuming the highest collected and permanent body of water to be the true head, the source of the Hudson is Lake Tear-of-the-Clouds, which lies near Mount Marcy at an elevation of about 4322 ft. The sources of the river are in the wildest part of the Adirondack Mountains, in Essex county, north-eastern New York. The Hudson lies entirely in the state of New York, which it crosses in a nearly north-and-south direction near the eastern boundary of the state. It is not a river in the truest sense of the word, but a river valley into which the ocean water has been admitted by subsidence of the land, transforming a large part of the valley into an inlet, and thus opening it up to navigation.

HUDSON RIVER, the principal river of New York state, and one of the most important highways of commerce in the United States of America.
