The mountain called by this name is a remarkable precipice in Great Barrington, overlooking the rich and picturesque valley of the Housatonic, in the western part of Massachusetts. At the southern extremity is, or was a few years since, a conical pile of small stones, erected, according to the tradition of the surrounding country, by the Indians, in memory of a woman of the Stockbridge tribe who killed herself by leaping from the edge of the precipice. Until within a few years past, small parties of that tribe used to arrive from their settlement in the western part of the State of New York, on visits to Stockbridge, the place of their nativity and former residence. A young woman belonging to one of these parties related, to a friend of the author, the story on which the poem of Monument Mountain' is founded. An Indian girl had formed an attachment for her cousin, which, according to the customs of the tribe, was unlawful. She was, in consequence, seized with a deep melancholy, and resolved to destroy herself. In company with a female friend, she repaired to the mountain, decked out for the occasion in all her ornaments, and, after passing the day on the summit in singing with her companion the traditional songs of her nation, she threw herself headlong from the rock; and was killed.
