Jack noticed that the dippers seemed to dive into the upper part of the pool, and to be carried down by the swift current close to a little point of rocks, and slowly walking out there, and standing perfectly still, he soon saw one of the birds drop down from a large stone near him, and disappear under the water. He could see a sort of a flying shadow under the surface, and in a moment the bird came up a little below him, and flew off to the other side of the stream. As it grew darker, the dippers disappeared, having probably gone to their roost; and as the two returned to camp, Hugh said to Jack, "Son, did you ever see one of the nests made by these birds?"

"No, Hugh, I never did," said Jack.

"Well, we must be on the lookout for that. They're mighty queer little nests. On the outside they seem to be made of green moss, so that the nests look just like a bunch of moss growing on a rock. Often they build them close under some little water-fall, and I expect maybe it's the mist from the fall that keeps the moss wet and growing; but if the outside is damp and wet, the inside is just as dry as can be, and the young birds have a good warm place, and a good roof over their heads. It's kind of fun to watch one of these nests and see how hard the old birds have to work to keep the young birds quiet. They come with an insect, and give it to some one of the young ones, and then dart off, and are not gone more than a few minutes, and then come back again, so both the old birds keep travelling back and forth; and all the time the young ones are making all the noise they can, only you can't hear'em for the sound of the water—they're a hungry lot, I tell you. Of course, the breeding season is past a long time now, and maybe if we keep our eyes open we'll be able to see a nest and get it for you to take home with you, though often they're in a place where it's mighty hard to get at them."

The little circular meadow in which they had camped was not large enough to give good feeding for their horses, even if the ground had not been covered with snow; but Hugh felt certain that the horses would not try to follow the back trail up the hill again, nor did he think that they would venture away down the stream into country unknown to them. However, he picketed two horses and hobbled most of the others, and when morning came they were most of them in sight, though one or two had strayed away into the timber. The snow on the ground made it an easy matter to follow them, and soon after sunrise the train had started on again.

The travelling was better than had been expected. Although sometimes the walls of the valley drew so close together that there was hardly room for the stream to flow, they managed to get along without very much climbing, and were all the time going down hill. The next night when they camped, the snow had almost entirely disappeared from the valley, only patches lying in some of the most shady spots. There was abundant sign of game here, but they saw none, nor did they look for it. The next afternoon however, Hugh stopped as they were crossing a meadow, and, calling Jack to him, pointed out some tracks in the soft ground, which Jack at first supposed were elk tracks, but on more careful examination found to be quite different; and after thinking for a moment, he asked Hugh if they could be moose tracks.

"Yes," said Hugh, "that's just what they are. This was a good bull, and he crossed here early this morning. Follow his tracks a little way and see if you can make out anything special about them, and then come on after us and tell me what you saw."

Jack followed slowly along on the tracks until they entered the timber. Then he returned to take his position in the pack train. By this time the way was so open that it was not necessary to travel in single file, and Jack, riding up to Hugh said, "Well, Hugh, those tracks are about twice as long as an elk's track, and only a little bit wider; that makes them look long and narrow. Then, besides that, I noticed that whenever the animal went over a soft spot, and his foot sank in a little, there seemed to be two marks behind the main track, and I suppose those are the dew claws sinking in. Is that so?"

"That's it," said Hugh, "I'm glad you took notice so carefully. Maybe we'll get a chance to kill a moose before we get down out of these mountains. We don't really want one now; but you've never seen a moose, and I expect if one should show up, why maybe you'd want to shoot at it."

"Well, Hugh, I guess I would," said Jack; "but I suppose as long as we're travelling here with the pack train, and making so much noise, there isn't much chance of our seeing one."

"No, not much," said Hugh.
