The next morning they made an early start, and following up the Firehole, turned up a branch coming in from the east, only a short distance beyond Old Faithful. They purposed to go over to Shoshone Lake, and camp there, and to do this they must pass over the Continental Divide, for the Firehole finds its way through the Madison River, and the Missouri, to the Atlantic Ocean, while the waters of the Shoshone Lake fall into Snake River, then into the Columbia, and so at last reach the Pacific.
The way was pleasant, through park-like openings and green timber, and the distance not great. There was no trail, but they followed up a narrow grassy valley, whose slopes on either side were clothed with pines.
At last, when Hugh thought they must be near the Divide, they found down timber, and began to wind about among the logs. Little by little, however, matters grew worse, and presently a stick was encountered over which old Baldy could not step, but on which he caught his foot and almost fell. Here all hands dismounted, and getting an ax out of a pack, Hugh and the boys went ahead, and by lifting some of the larger sticks, and breaking smaller ones, and a little chopping, a way was soon made by which the horses could pass along.
Beyond this timber was an open and almost level country, which Hugh declared was the Divide, and passing along a little further, they began to go down a gentle hill. Here there were park-like meadows and low wooded hills on either side. There were a few little gullies, but no water; and in the dry stream-beds and water-holes were many tracks of elk, all made in the spring when the ground was soft. From the summit of this Divide, when snows are melting in the early summer, little trickles of water pour down the opposite sides of the mountains, some to the north, to find their way into the Firehole; others south toward Snake River. Hugh followed the general direction of one of these water-courses, which constantly grew larger, and presently turned into one still wider, whose sandy bottom was dotted with great blocks of black lava. Hugh pointed out these to the boys, and said to them, "That's the stuff that in old times many of the Indians used to make their arrow points from. It must have been a great article of trade, for away up north of the boundary line I have seen little piles of chips of that black glass lying on the prairie, where men have been making arrow-heads, and I know that there wasn't any of the rock within 400 miles."
All along the valley of this dry stream was a beautiful park of gently rolling country, with timbered knolls and open grassy intervales. Some of the trees were very large—two or three feet in diameter.
It was early in the afternoon when they reached Shoshone Lake, and riding along its smooth, firm beach, camped in a little point of spruces. The lake was large, and looked as if it should have a fish in it. Jack got out his rod and put it together, and standing it against a tree, went back into the open meadow where the horses were feeding, to catch grasshoppers. He caught half a dozen, and then, returning, fished faithfully for quite a long distance along the shore, but without success. Neither could he see anywhere that fish were rising, and he wondered whether it could be possible that this beautiful lake, which seemed an ideal home for trout, should have none in it. Joe, on the other hand, as soon as camp had been made, had taken his rifle and started out on foot, working along the edge of the lake and looking for game. He found many old elk tracks and a very few made by deer, but went quite a long distance without seeing anything. Then, turning away from the shore of the lake, and taking the hillside at some distance from it, he began to work back to the camp. Here there were more deer tracks, but none that seemed worth while for him to follow, and he began to feel discouraged. When he had come almost opposite the camp he crossed a wide dry water-course, going now rather carelessly, though still making no noise, yet not trying to keep out of sight. As he climbed the gentle slope, after crossing the little valley, and had almost reached the top, he stopped, and turned about and looked backward, and there to his astonishment saw, projecting above a patch of low willows and weeds, the heads of two fawns. They were staring at him most innocently, but the camp needed meat, and bringing his rifle to his shoulder he fired at the neck of one of them, and the little deer disappeared, while the other turned about and raced away through the brush.
Going to the place Joe found the fawn quite a small one, though it had already lost its spotted coat. He dressed it, and then throwing it on his shoulders walked quickly to the camp. As he came in front of the lodge, Hugh said to him, "Hello, Joe, what have you got there, a jack rabbit?"
"Well," said Joe, "it is not much bigger, but it's the only thing I have seen except another of the same size, and that I could not shoot at."
That night as the sun went down the wind began to blow a fresh dry wholesome breeze from the west. The wind raised quite a sea on the lake, and big waves tumbled up on the beach one after another, so fast that it was not an easy matter to get a bucket of water without at the same time getting a wet foot. Jack and Joe walked along the beach a little way.
"Do you know, Joe," said Jack, "this looks to me just like the seashore; the wind blows in the same way, and the waves have the same white-caps, and the surf roars as it pounds on the beach; and there is the moon on the water. Why it seems to me just like some nights I have walked on the beach, back east on the Long Island shore."
