To these Berkshire hills the visitors go to see the brilliant autumnal tints of the American forests in their greatest perfection. When copious autumn rains have made the foliage luxuriant, much will remain vigorous after parts have been turned by frosts. This puts green into the Berkshire panorama to enhance the olives of the birch, the grayish pinks of the ash, the scarlets of the maple, the deep reds of the oak and the bright yellows of the poplar. When in such a combination, these make a magnificent contrast of brilliant leaf-coloring, and while it lasts, the mantle of purple and gold, of bright flame and resplendent green, with the almost dazzling yellows that cover the autumnal mountain slopes, give one of the richest feasts of color ever seen. This magnificence of the Berkshire autumn coloring inspired Beecher to write, "Have the evening clouds, suffused with sunset, dropped down and become fixed into solid forms? Have the rainbows that followed autumn storms faded upon the mountains and left their mantles there? What a mighty chorus of colors do the trees roll down the valleys, up the hillsides, and over the mountains!" From Williamstown to Salisbury the region stretches, the Taghkanic range bounding it on the west, and the Hoosac Mountain on the east. The northern guardian is double-peaked Old Graylock, the monarch of the Berkshire hills, in the Taghkanic range, the scarred surfaces, exposed in huge bare places far up their sides, showing the white marble formation of these hills.
