Following the curving Hudson River bank around to the westward, another series of rapids and cascades is ascended to the thriving manufacturing town of Glen's Falls. This magnificent cataract pours through a wild ravine having over seventy feet descent, the water flowing upon rough masses of black marble composing the rocky terraces the stream has broken down. The Mohicans had significant names for this famous cataract. One was Kayandorossa, meaning the "long deep hole," applied to the ravine; and another, Che-pon-tuc, or "hard climbing; a difficult place to get around." Along the north side of the ravine, upon a beautiful plain, is the manufacturing settlement of about ten thousand people, who use the admirable water-power and get the black marble out of adjacent quarries. Vast numbers of logs coming down the Hudson are gathered in a boom above the town, and sawmills cut them into lumber. Paper-mills cluster about the falls, and marble-saws work up the black rocks. In the centre of the ravine, above the falls, a cavern is hewn where a rocky islet makes a rude abutment for a bridge pier. Father Jogues, who came over from Lake George in 1645, was the first white man who saw this attractive region, and he wrote that the Indians then called the Hudson "Oi-o-gue" or "the beautiful river," while the Hollanders, settled on it farther down, had named it the "river Van Maurice." When the Dutch made their first explorations they found that the lower Mohawk and the upper valley of the Hudson, with the country northward extending into the Adirondacks, was the home of the Mohicans, an Algonquin tribe, and always at war with the Mohawks, their western neighbors higher up that valley. It was thought probable that with a view of securing assistance in this inveterate feud, the Mohicans received the Dutch settlers so amicably and gave them lands.
