Above, the lake gradually broadens, and at the widest part are seen, on opposite sides, the village of Port Kent with its furnaces, and the flourishing Vermont city of Burlington. The great Adirondack ridge of Trembleau runs abruptly into the water as a sort of guardian to Port Kent, and just above, Ausable River flows out through its sandy lowlands into the lake. Vermont, which makes the entire eastern shore of Champlain, is a region of rural pastoral joys with many herds and marble ledges, a land of fat cattle and rich butter-firkins, overlooked by mountains of gentle slope and softened outline. Southward from Lake Champlain is Bennington, in a mountain-enclosed valley, near which was fought in August, 1777, the famous battle in which Colonel John Stark's Green Mountain boys cut off and signally defeated Baum's detachment of Burgoyne's army. It is now a flourishing manufacturing town. East of the head of Lake Champlain is Rutland, the centre of the Vermont marble-quarrying industry and the site of the great Howe Scale Works, a city of twelve thousand people. Three-fourths of the marble produced in the United States comes from this district of Vermont, and the Sutherland Falls Quarry at Proctor, near Rutland, is said to be probably the largest quarry in the world. These quarries are in the flanks of the Green Mountains which stretch northward, making the watershed between the upper Connecticut River and Lake Champlain. The Killington Peak, forty-two hundred and forty feet high, is not far from Rutland.
