These springs surpass in extent, variety and beauty any which we have heretofore seen. They extend for the distance of nearly a mile along the shore of the lake, and back from the beach about one hundred yards. They number between ninety and one hundred springs, of all imaginable varieties. Farthest from the beach are the springs of boiling mud, in some of which the mud is very thin, in others of such a consistency that it is heaped up as it boils over, gradually spreading under its own weight until it covers quite a large surface. The mud or clay is of different colors. That in some of the springs is nearly as white as white marble; in others it is of a lavender color; in others it is of a rich pink, of different shades. I have taken specimens of each, which I will have analyzed on my return home.[V] In close proximity to these are springs discharging water nearly clear and apparently odorless, the bottoms and sides of which, as well as of the channels of the streams running from them, are covered with soft deposits of some substance they contain in solution. These deposits and the hard incrustations around the edges of the springs are of various colors, in some cases being dark red, in others scarlet, in others yellow, and in still others green. Along the shore of the lake are several boiling springs situated in the top of incrusted craters, but which do not boil over, the sediment which has been deposited around them forming a wall or embankment, holding back the water. But the most remarkable of all the springs at this point are six or seven of a character differing from any of the rest. The water in them is of a dark blue or ultra-marine hue, but it is wonderfully clear and transparent. Two of these springs are quite large; the remaining five are smaller, their diameters ranging from eight to fifteen feet. The water in one of these latter is thrown up to the height of two feet. The largest two of these springs are irregular in their general outline of nearly an oval shape, the larger of the two being about twenty-five feet wide by forty long, and the smaller about twenty by thirty feet. The discharge from each of them is about one gallon per minute. The sides of the springs are funnel-shaped, and converge until at the depth of thirty feet, the opening is about eight feet in diameter. From the surface or rim down to the lowest point of convergence where the opening enlarges, the sides of the funnel (which are corrugated and very uneven and irregular) are covered with a white deposit or incrustation which contrasts vividly with the dark opening at its base, which is distinctly visible at the depth of forty feet. These two springs are distant from each other about twenty yards, and there is a difference of about four feet in the elevation or level of the water. One peculiar feature of all these springs is that they seem to have no connection with each other beneath the surface. We find springs situated five or six feet apart, of
