Sinking back against a rock, and grinding his teeth with pain, he strove to concentrate his attention upon the problem that confronted him. Was he to die of thirst and hunger on this high solitude before he could recover sufficiently to climb down? The thought stirred all his dogged determination. He _would_ keep alive, and that was all there was about it. He _would_ get well, and then the climbing down would be no great matter. This point settled, he dismissed it from his consideration and turned his thoughts to ways and means. After all, there was that little thread of a spring trickling from the rock! He would have enough to drink. And as for food--how much worse it would have been had the ledge been a bare piece of rock! Here he had some grass, and the roots of the herbs and bushes. A man could keep himself alive on such things if he had will enough. And, as a last resource, there was the young eagle! This idea, however, was anything but attractive to him; and it was with eyes of good-will rather than of appetite that he glanced at his fellow-prisoner sitting motionless at the other extremity of the ledge. "It'ld be hard lines, pardner, ef I should hev to eat you, after all!" he muttered, with a twisted kind of grin. "We're both of us in a hole, sure enough, an' I'll play fair as long as I kin!" As he mused, a great shadow passed over his head, and looking up, he saw one of the eagles hovering low above the ledge. It was the male, his old acquaintance, staring down at him from under that strange, black brow. He carried a large fish in his talons, and was plainly anxious to feed his captive young, but not quite ready to approach this mysterious man-creature who had been able to invade his eyrie as if with wings. Horner lay as still as a stone, watching through half-closed lids. The young eagle, seeing food so near, opened its beak wide and croaked eagerly; while the mother bird, larger but wilder and less resolute than her mate, circled aloof with sharp cries of warning. At last, unable any longer to resist the appeals of his hungry youngster, the great bird swooped down over him, dropped the fish fairly into his clutches, and slanted away with a hurried flapping which betrayed his nervousness. As the youngster fell ravenously upon his meal, tearing it and gulping the fragments, Horner drew a deep breath. "There's where I come in, pardner," he explained. "When I kin git up an appetite for that sort of vittles, I'll go shares with you, ef y'ain't got no objection!" Having conceived this idea, Horner was seized with a fear that the captive might presently gain the power of flight and get away. This was a thought under which he could not lie still. In his pocket he always carried a bunch of stout salmon-twine and a bit of copper rabbit-wire, apt to be needed in a hundred forest emergencies. He resolved to catch the young eagle and tether it securely to a bush.
