"Oh, don't give up so soon," returned Dave. "Remember we have the whole day before us." Presently Ben and Luke, who had turned southward on the cliff, let out a shout. "Here is something of a trail," announced Ben, when the others came hurrying in that direction, and he pointed to footprints which led through some soft soil between a number of low bushes. A little further on they could see where somebody's shoes or boots had carried some of the mud up on to the rocks beyond. "That certainly does look like a trail," declared Dave. "Let us follow it up a bit, and see where it leads to." This was considered good advice, and soon, led by our hero, the whole party was moving through the brushwood and over the rocks. Then they came once again to the woods, and here discovered a well-defined trail running southwestward. "This may be an animal trail for all we know," remarked Shadow. "For my part, I can't tell one kind of trail from another." "It's quite likely that a fellow like that wild man would use any trail he came across, and so would anybody else trying to move around in a wilderness like this," answered Dave. "I don't think it will do any harm to follow it for some distance." "Better keep your eyes open, Dave," cautioned Phil. "It may lead us into danger." "I've got my eyes wide open, and I've got the rifle handy, too," answered our hero, as he once more led the march forward. The trail was very narrow in places, so that they had to walk in single file. It made a long curve through the forest, and then came out in a little clearing, backed up by a series of jagged rocks. Here there was a small stream, and behind it a spring of pure, cold water. "It looks to me as if the animals used this trail when they wanted a drink," was Luke's comment. "That water looks pretty good to me," and bending down, he took a deep draught. "It's fine," he went on; "try it!" The others did as requested, and agreed with Luke that the water was as good as any they had ever tasted. Then began more searching, and before long they found another trail, this time veering to the westward. The boys pushed forward once again, Dave still in the lead; and thus a half mile more was covered. Then they found themselves between a number of rocks where, presently, the trail seemed to lose itself. "Say, Dave, we don't seem to be getting anywhere," announced Phil, as having climbed over several very rough rocks, he stopped to regain his breath. "That's right!" broke in Luke. "And say, we had better go slow unless somebody wants to sprain an ankle. This is the roughest ground I ever tried to get over." "It is easier walking just ahead," announced Dave, who now stood on the top of one of the rocks, gazing forward. "Come on! I think I see the trail too," and he made a leap from one rock to another and was soon some distance in advance.
