He was rather ahead of me, and on overtaking him I found him standing by the side of a circular basin whose diameter we calculated to be fully twenty feet. The contents consisted of what greatly resembled hasty pudding, or, as Manley said, "a huge caldron of thick mash." The whole surface was bubbling up every instant, and giving off a thud like the noise produced by the escape of the gas below.

Curious as these sights were, we were still more astonished by the appearance of the side of the mountain, the base of which we passed. All up the slope was seen, as it were, one above another, a succession of large basins or reservoirs. The margins were beautifully scalloped and adorned with natural bead-work of exquisite beauty. In spite of our hurry, we could not resist the temptation of making our way up to them. One of the largest springs we calculated to be fully thirty feet in diameter; and so perfectly transparent was the water, that, as we looked down into it, we could see to the very bottom. Its sides were ornamented with coral-like forms of various shades, from pure white to bright cream-yellow, while the blue sky overhead gave an azure tint to the whole surface which no art could imitate. Over several parts of the rim the water was flowing down into other basins. I climbed up and looked over into one of the pools, which was literally hanging on to the one above it like a bird's nest to a wall; while beautiful stalactites were suspended below it, caused by the water which flowed over the sides. The temperature of the water when it came out of the side of the mountain was high, but in the course of its passage from pool to pool it became gradually cooler.

"I cannot resist the temptation of taking a bath in one of these beautiful basins," exclaimed Manley.

Selecting one, I followed his example; and the sergeant was soon sitting in a third, with his head just above the water. Nothing could be more refreshing and invigorating, and when we got out we all agreed that we felt better able to continue our journey.

CURIOUS HOT-WATER "BATHS."

We found that the clear atmosphere of this region greatly deceived us as to distances, and it was not until the following day that we arrived on the shores of the lake. It was nearly evening when, after having penetrated a thick pine forest, we at length stood on its borders. Few lake-scenes could be more beautiful than that now spread out before us. The southern shore was indented with long narrow inlets, while pine-crowned promontories stretched from the base of the hills on every side. Islands of emerald hue dotted its surface, and round the margin was a sparkling belt of yellow sand. The surface, unruffled by a breath of air, was of a bright green near the shore, shading into a dark ultramarine towards the centre. Whether there were fish, we had yet to discover; but we had no fear of starving, for the whole surface of the lake swarmed with birds—swans, gulls, pelicans, geese, herons, brants, sand-hill cranes, and many varieties of ducks. An island in view was literally white with the numbers of pelicans which had taken up their abode upon it. We had also seen many other birds during the day—eagles, hawks, ravens, ospreys, prairie-chickens, grouse, mocking-birds, and woodpeckers; while we caught sight of several kinds of deer, elk, and mountain sheep. Even buffalo had made their way into the valley. Grizzly bears and panthers, too, we had good reason to fear, abounded, and were likely to be troublesome to us.

We formed our camp on the shore of the lake, where there was fuel in abundance; and taking my gun, in the course of a quarter of an hour I shot geese and ducks enough to give us an ample supper, and breakfast next morning. Manley, who was a good angler, had, in the meantime, been fitting up a rod and line—for he had brought hooks with him; and I found, when I got back, that he and the sergeant had caught a dozen salmon-trout, between a pound and a pound and a half in weight. Their colour was of a light gray above, and a pale yellow below. The dorsal and caudal fins were dark gray, and the others mostly of a brilliant orange or bright yellow.

We calculated that the lake was fully twenty miles long, and not less than fifteen broad in its widest part; and had we not been in a hurry to proceed on our journey, we agreed that we would have willingly spent some days in this enchanting spot. However, this was not to be thought of.
