This had been made along the bank of the deep, still stream which supplied the camp with ice-water from the Sierra Madre. Nobody ever heard of any fellow taking a swim in such cold water as that was. It was cold enough to chill the bones of a mountain trout. Of course no one did undertake to swim in it, but, at about midnight, a log came floating down. There was a large knot on one side of the log. The current or something carried it against the bank, right in the middle of the corral, and either there were two logs, or that log divided, for one log floated off down stream, while the other log crept out on shore, stood erect, and walked stealthily around among the horses. The knot was carried on the upper end of this log, and the other went off without any.

Very quickly were four of the best horses fixed with four of the best saddles and bridles from among the long rows at the edge of the corral. The log did it, and added holsters with revolvers in them and two bundles of fine lances and some good American carbines, and two full straddle packs of cartridges. The sentries of the corral were all stationed away outside of the place where that peculiar log was at work. All but two of them were asleep, as the guardians of so strong and warlike a camp had a right to be.

Now the log crept around until it found a path leading out southerly, past a sentry who was sleeping very soundly indeed. Then it went back into the corral and led out the four saddled and bridled horses, with four others following that wore only halters, but carried securely strapped burdens, selected and fitted by the log.

There was a brilliant moonlight, so that there was no danger whatever to the camp from Indians, and the log led the horses on until it became wise to go ahead and see if there had been any picket posted at the place and distance at which one might have been expected.

"Ugh!" exclaimed the log, as it went back for the horses. "Mexican! No blue-coat!"

That was a compliment to such men as Captain Moore, but then the log was doing what no kind of fellow would have undertaken with "blue-coats." It now mounted one of the horses and led on up the stream, to a place it seemed to know about, where the water was wide and shallow and could be easily forded. On crossing it the log was still at no great distance from the camp, but upon higher ground. Looking down, it could have a good view of the smouldering camp-fires and the sleeping Mexicans, for tents there were not.

"Kah-go-mish is a great chief!" exclaimed the knot at the top of the log, exultingly. "Ugh! Got heap hoss, heap saddle, heap gun, heap all plunder. Ugh! Mexican shoot at him on rock. Wonder how feel now, pretty soon. Ugh!"

An irrepressible whoop of triumph burst from him.

"Ugh! Bad medicine," he said. "Great chief let mouth go off like boy."

He had not lost his wits, however, and he followed that whoop with a dozen more, a whole series of fierce, ear-splitting screeches, while he rapidly emptied the nine chambers of the captured carbine and the six of a revolver. He aimed at the camp-fires and with tip-top success, testified to by sudden showers of sparks and brands which flew around among the startled sleepers.
