hills, following up the retreating line of the melting snows, in springtime and, later on, decorating the mountains with its fine feathery seed-heads. Here, too, the Wild Heliotrope (Valeriana sitchensis) grows in profusion, the pink Swamp Laurel (Kalmia glauca) and the White Mountain Rhododendron; Heaths and Heathers, red, rose, and white, carpet the earth beneath the Lyalls Larches, and are among the last vegetation seen at "tree-line"; the Globe Flower (Trollius laxus), a great white bloom with a heart of gold, pushes its way up through the icy coverlet of winter, and the Romanzoffia, with its petals of pure velvet, nestles in the crevices of the rocks at an elevation of 8000 feet.
