This was cheering news to the photographing Teuton, who could hardly eat any breakfast so impatient was he to be off. Cal was to stay and guard the camp with Ding-dong for a companion. The searching party was to consist of Nat, in command, with Joe and Herr Muller as assistants.
All, of course, carried weapons, and it was agreed that the signal in case of accident or attack, would be two shots in quick succession, followed by a third. Two shots alone would announce that the horse was found; while one would signify failure and an order to turn homeward.
These details being arranged, and Herr Muller thoroughly drilled in them, the searchers set forth. The little meadow was soon traversed, and at the edge of the woods, which clothed the slope at this side of the valley, they separated. Nat took the centre, striking straight ahead on Bismark's trail, while the other two converged at different radii.
The hill-side was not steep, and walking under the piñons and madrones not difficult. Occasionally a clump of dense chaparral intervened, so thick that it had to be walked around. It would have been waste of time to attempt to penetrate it.
All three of the searchers, as may be imagined, kept a sharp look-out, not only for trace of Bismark but also for any sign of danger. But they tramped on, while the sun rose higher, without anything alarming making itself manifest.
But of Bismark not a trace was to be found. He had, apparently, vanished completely. The ground was dry and rocky, too, which was bad, so far as trailing was concerned. Nat, although he now and then tumbled on a hoof mark or found a spot where Bismark had stopped to graze, saw nothing further of the horse.
At last he looked at his watch. He gave an exclamation of astonishment as he did so. It was almost noon.
"Got to be starting back," he thought, and drawing his revolver, he fired one shot, the signal agreed upon for the return.
This done, he set off walking at a brisk pace toward what he believed was the valley. But Nat, like many a more experienced mountaineer, had become hopelessly turned around during his wanderings. While it seemed to him he was striking in an easterly direction, he was, as a matter of fact, proceeding almost the opposite way.
