According to custom with these mountaineers, a portion of territory was given to them for their occupancy by consent of the tribe; for individual right to territory is not claimed, nor would it be tolerated. Ten-ie-ya staid with the Monos until late in the summer or early autumn of 1853, when he and his people suddenly left the locality that had been assigned to them, and returned to their haunts in the Yosemite valley, with the intention of remaining there unless again driven out by the whites. Permanent wigwams were constructed by the squaws, near the head of the valley, among the rocks, not readily discernable to visitors. Not long after Ten-ie-ya had re-established himself in his old home, a party of his young men left on a secret foraging expedition for the camp of the Monos, which was then established at or near Mono Lake. According to the statement made to me, there had just been a successful raid and capture of horses by the Monos and Pai-Utes from some of the Southern California ranchos, and Ten-ie-ya’s men concluded, rather than risk a raid on the white men, to steal from the Mono’s, trusting to their cunning to escape detection. Ten-ie-ya’s party succeeded in _recapturing_ a few of the stolen horses, and after a circuitous and baffling route through the pass at the head of the San Joaquin, finally reached the valley with their spoils. After a few days’ delay, and thinking themselves secure, they killed one or more of the horses, and were in the enjoyment of a grand feast in honor of their return, when the Mono’s pounced down upon them. Their gluttony seemed to have rendered them oblivious of all danger to themselves, and of the ingratitude by which the feast had been supplied. Like sloths, they appear to have been asleep after having surfeited their appetites. They were surprised in their wig-wams by the wronged and vengeful Monos and before they could rally for the fight, the treacherous old chief was struck down by the hand of a powerful young Mono chief. Ten-ie-ya had been the principal object of attack at the commencement of the assault, but he had held the others at bay until discovered by the young chief, who having exhausted his supply of arrows, seized a fragment of rock and hurled it with such force as to crush the skull of “the old grizzly.” As Ten-ie-ya fell, other stones were cast upon him by the attacking party, after the Pai-ute custom, until he was literally stoned to death. All but eight of Ten-ie-ya’s young braves were killed; these escaped down the valley, and through the cañon below.
