Among the many beautiful formations made by these Hot Springs, the most elaborate and ornamental are the Pulpit Terraces. These are a succession of magnificent terraces, fifty feet high, with beautifully colored columnar supports. There is a large pulpit, and in front, on a lower level, the font, with the water running over its edges. The pulpit, having been formed by a spring that has ceased action, is white, while the font is streaked in red and brown. Finely carved vases filled with water stand below, and alongside the pulpit there is an inclined surface, whitened and spread in wrinkles like the drifted snow, which requires very little imagination to picture as a magnificent curtain. Beyond is a blackened border like a second curtain, the coloring being made by a spring impregnated with arsenic. In front of this gorgeous display the surface is hot and cracked into fissures, with bubbling streams of steaming water running through it, and great pools fuming into new basins with turned-up edges, over which the hot water runs. Upon one of these pools seems to be a deposit of transparent gelatine, looking like the albumen of an egg, streaked into fantastic shapes by elongated bubbles. Everywhere are surfaces, over which the water runs, that are covered with regular formations like fish scales. It is impossible to adequately describe this extraordinary place, combining the supposed peculiarities and terrors of the infernal regions with the most beautiful forms and colors in decoration. The great hill made by these Hot Springs was, from its prevailing color, named the White Mountain by Hayden. The springs extend all the way down to the river bank, and there are some even in the river bed. It is a common experiment of the angler to hook a small fish in the cold water of the river, and then, without changing position, to swing him on the hook over into the basin of one of these hot springs to cook him. The formation of the terraces is wedge-shaped, and runs up into a gulch between the higher mountains, which have pines scattered over them, and also grow some grass in sheltered nooks. It is said that the volume of the springs is gradually diminishing. THE NORRIS GEYSER BASIN.
