Presently they came to a broad opening, and saw before them the lake. At the outlet the grass grew thick and rank, and in the marshes, pond-holes and sloughs here, they saw many flocks of wild ducks and geese; and sand-pipers and beach birds fed along the shore. Some swans were seen, and a few great white pelicans.
Their fresh meat was now exhausted, and for a day or two they had been living on trout, of which great numbers were caught in the streams that they had crossed, for fish are abundant everywhere in the mountains. When they made camp that night, Jack got out his line, and cutting a pole, went down to the shore to catch some fish, while Hugh and Joe made the fire.
Jack had hardly thrown his hook in the water when it was seized, and he dragged a large fish to shore. As he was taking it off the hook however, he noticed a bunch on its side, and after examining it for a moment, cut into this bunch with his knife, and drew from it a long white worm. He got a dozen trout, but all of them seemed to be afflicted with this parasite, and finally putting up his line he carried them to the fire, and showed them to Hugh. Both Hugh and Jack agreed that these fish were not fit to eat, and that night they supped on dried meat and back-fat.
As they had made camp that night they had noticed, just beyond them, two white tents, and had seen some horses feeding near the lake shore. Shortly after their supper, a man walked into the camp, and after saluting them, sat down by the fire. A little talk showed that he was a member of the geological survey that worked in the Park, and he had been attracted to their camp by the fact that they had an Indian lodge. He was a pleasant man, and seemed quite willing to talk, and to answer all their questions, and very much interested in his work. After he and Hugh had talked together for a while, Jack ventured to ask some questions about the Park, and especially about the place where they now were. "Won't you tell me, sir," he said, "what you can about this big lake that we are on. It looks to me awful big to be up here high in the mountains. Of course I know it isn't anything like the Great Lakes; still it's the largest lake I ever saw."
"It is a large lake," said their visitor, "for it contains about 150 square miles of water, and there is probably no lake in North America of equal size at so great an elevation. You see, we are about 7700 feet above the level of the sea. Roughly speaking, the shape of the lake is like that of an open hand which lacks the first and middle finger; the wrist is the northern end of the lake, the west arm answers to the outstretched thumb, and the south and southeast arms to the ring and little finger. If you are going to travel around it, you will feel that it is a lovely sheet of water. It is very picturesque, and in fair weather it lies here like a great sapphire beneath the unclouded sky. But when the storms come up, and the wind rolls down along the mountain sides, the lake can get up a great sea, and one would not care to be out on it. But in fair weather it is very beautiful—to me the loveliest spot in all the park. And what is more, I never get tired of it; the more I see it, and the more familiar I become with its scenery, the lovelier it is. From every promontory and every bay, and from every hillside above it, one has always a different view, and each view has a charm that is all its own."
The geologist sat there long with them that night, talking to them in a most interesting way about the Park and the geysers and the cañons. He told them that all this country was volcanic in origin, and that for some reason or other, which he did not know, the heat still remained close to the surface of the earth; and that this was the reason that there were so many hot springs and geysers here.
"It's one of the most interesting regions in the world," he said, "and one of the most beautiful. As yet, people do not appreciate it. Many people do not even know that it exists; but the time will come when thousands will gather here each summer, from all quarters of the world, to see its beauties. Geologically, it is most interesting, and already geologists from all over the world are coming to see it, or are making plans to come. I predict that the time is coming when the Yellowstone Park will be acknowledged to be the most wonderful place in the world."
As the visitor rose to go, he looked about the lodge and said, "So this is an Indian lodge, is it? I've often read about them, but this is the first one I've ever seen. They seem warm and comfortable, but are they not rather smoky?"
"No," said Hugh, "they're not smoky; but you must remember they're not made to stand up in; people in the lodge are expected to sit down, or to lie down. If there's a fire burning, and no wind blowing, or if the air is damp and heavy, smoke often gathers in the top of the lodge, and a man standing in it finds about his head more than he likes. Stoop down a little bit and you will see that the smoke no longer troubles you." The geologist did as Hugh advised, and seemed to be greatly interested by the discovery that it was as he had said; and then bidding them good night, he left the lodge.
