"Ascending the Saranac River, we struck out into the broad Saranac Lake, some six miles in length, and though the winds and the waves buffeted us, the canvas sides of the boat responding elastically to each beat of the waves, we got safely along till near the Sister Islands, when, the wind blowing very fresh, the white-capped rollers began to pitch into the boat. The exertions of the guides brought us under the lee shore, and at evening we disembarked at Martin's." Geographies, guide-books, and historical works frequently give the length of Lake Champlain as one hundred and fifty, or at the least one hundred and forty miles. These distances are not correct. The lake proper begins at a point near Ticonderoga and ends not far from the boundary line of the United States and Canada. Champlain is not less than one hundred nor more than one hundred and twelve miles long. The Champlain Canal, which connects the river that flows from Whitehall into the lake with the Hudson River, is sixty-four miles long, ending at the Erie Canal at Junction Lock, near Troy. From Junction Lock to Albany, along the Erie Canal, it is six miles; or seventy miles from Whitehall to Albany by canal route. This distance has frequently been given as fifty-one miles. From the United States boundary line south-ward it is a distance of seven miles to Isle la Motte, which island is five and a half miles long by one and three quarters wide, with a lighthouse upon its northwest point. From the New York shore of Monti Bay, across the end of Isle la Motte to St. Albans, Vermont, is a distance of thirteen and a half miles. Two miles south of the island, on the west shore, is Point au Roche light; and two miles and three quarters south of it is Rocky Point, the terminus of Long Point. Next comes Treadwell Bay, three miles across; then two miles further on is Cumberland Head and its light-house. West from Cumberland, three miles across a large bay, is Plattsburgh, at the mouth of the Saranac River, a town of five thousand inhabitants. In this vicinity Commodore Macdonough fought the British fleet in 1814. These are historic waters, which have witnessed the scene of many a bloody struggle between French, English, and Indian adversaries. Off Cumberland Head, and dividing the lake, is Grand Isle, twelve miles in length and from three to four in width. The village of Port Kent is near the mouth of the Ausable River, which flows out of the northern Adirondack country. A few miles from the lake is the natural wonder, the Ausable Chasm, which is nearly two miles in length. The river has worn a channel in the Potsdam sandstone formation to a depth, in places, of two hundred feet. Between high walls of rock the river is compressed in one place to ten feet in breadth, and dashes wildly over falls and rapids on its way to Lake Champlain. It is said to rival the famous Swiss Gorge du Triant.
