He got off his horse, slipped the loop of the bridle-rein over his left arm, slung the carbine across his right shoulder, and cautiously walked on. There was, of course, no trail or path at the base of the bluffs along which he was travelling, so he stopped at the mouth of every ravine he came to, hoping to find a pool of water, or to discover some hidden spring whose source was high up among the great rocks that towered above his head. Presently he arrived at a depression in the earth in the bottom of a gully, evidently made by the claws of some animal, for beside those marks were the imprint of foot-tracks. Joe intuitively guessed they were those of a panther, as he had been told by the old trapper, Tucker, that that animal knows by instinct when the water is near the surface, and scratches with his claws until he reaches it. Joe knew, too, that the panther was not a very large one; his footprints were too small; so he did not feel at all alarmed at their sight. On the contrary, boy-like, he was delighted at the idea of a possible tussle with one of the dreadful creatures, and he thought that if he could succeed in killing it he would add another feather to his cap by taking its hide home. Joe felt himself equal to a possible struggle. He knew that he was fully armed, and at once examined his carbine, took out the knife which he always carried in his belt for skinning, and finding everything in perfect order, he was really anxious to find the animal that had been digging for water only a little while before his arrival at the spot. A few rods further on, in the same ravine, he saw a little pool of water, evidently clear and cool, and after looking cautiously all around him, dipped the rim of his hat into the pool before him and indulged in a long drink of the delicious fluid. Then after having satisfied his thirst, he stood still for a few moments undecided as to what course he should pursue. [Illustration: "With one vigorous thrust of his knife he struck the animal's heart."] He concluded that if he was to remain and fight the panther if the animal made his appearance, it would be best to tie his horse to a sapling a short distance from the pool. After doing this he placed a fresh cartridge in his carbine and walked slowly on, following the beast's tracks, which had grown plainly visible a few paces from the edge of the water, and which soon led him into a rocky cañon. Joe came in sight of the panther much sooner than he expected. As he was turning the sharp projecting corner of a mass of rocks which formed the walls of a ravine, there was the panther sitting on a shelf of sandstone, not forty feet away from him. He was busy licking his paws cat-fashion, his ears cocked as if listening, and his small green eyes turned toward the intruder, but evidently not much concerned at the sight of his greatest enemy, man.
