THE WHITE TERRACES, SEEN FROM ABOVE.

"The White Terraces are on this side of the little lake, and the Pink Terraces on the other. Imagine, if you can, a series of irregular steps of silver or alabaster, or polished marble, about three hundred feet from side to side, and rising about two hundred feet from the shore of the lake. These steps or terraces have been formed by the crystallization of the silica contained in the hot water in the boiling lake above; the hot water holds it in solution, and as its temperature falls the silica is released and deposited.

"In the sunlight the terraces glistened and sparkled like a collection of all the precious stones in the world, and the picture was fascinating in the extreme. We ascended from the base to the edge of the boiling lake, where the terraces begin. Our guides cautioned us that we must expect to walk continually in the water which flowed over the terraces, but as the surface is soft and smooth we doffed our boots and encased our feet in moccasins, or shoes of untanned skin. The water at the bottom of the terraces is tepid; but each successive stage finds it hotter, and at last it is too much so for comfort. On one terrace after the other you find delightful tubs suitable for bathing; we should have bathed in them, but had been told to wait for the Pink Terraces, on the other side of the lake, where the baths are finer. There is just enough softness to the surface formed by the silica to make it pleasant to the touch and entirely safe to walk on without danger of slipping.

"Not only are the terraces beautiful, but the ornamentation which has been made by the hand of Nature, busily working here through many centuries, is beautiful in the extreme. The hanging ornaments and cornices at the outer edges of the terraces and on the rims of the baths surpass the work of the most gifted designer or the most vivid imagination. Description by words is out of the question, and I must fall back on the picture which I send with this.

"The boiling lake at the top of the White Terraces is a pool perhaps a hundred feet in diameter, and varying in height from time to time. Curiously enough, it changes with the wind, though why the wind should affect it I am unable to guess. It is boiling, boiling, boiling all the while, though more furiously at some times than at others. The water is a beautiful turquoise blue, and so intense is the blue that it reflects upon the cloud of steam that rises from the lake. In fact, nearly all the hot springs in this region are blue, and the color is perceptible at very slight depths.

"We wanted to spend a whole day here; but time pressed, and we descended to the lake again and crossed to the Pink Terraces. The lake is a tiny one, only a mile in length by half a mile in width.

THE PINK TERRACES, SEEN FROM BELOW.

"The Pink Terraces are smaller and lower than the White Terraces, and the spaces between the pools, or bathing-tubs, are not so finely wrought. The Pink Terraces are really not pink at all, but salmon-colored; the White Terraces have a tint of salmon, but it is less pronounced than in the other. The formation is the same in both, and having described one, it is hardly necessary that I should describe the other. We were eager for the promised bath, and were not long in getting at it. And such a bath!
