that the foremost sergeant, swinging his lantern aloft, sung out to his follower, "Watch out! It's blood!" and blood it proved to be--there and thereafter, down the opposite bank. Yet not a drop was seen on the sands where Willett fell. Then his assailants had not escaped unscathed. Unarmed as he was, the officer had made a desperate fight for life. "Now's the time to nab him!" said Turner, as he carried the report to Archer. "'Tonio has managed to elude Malloy's party, probably by leading them off on a false scent, but now we have blood to follow. Let me send out a platoon, mounted, and we may nail the gang before sunrise." It was then short of two o'clock, and while busy trailers followed on with their lanterns down the eastward bank, and were presently seen flitting like fireflies far south among the willows, Turner himself, with a score of his men, hastened back to quarters. There was saddling in hot haste, yet with the precision of long practice. By half past two all sight or sound of the trailers and the pursuing horsemen was lost in the distance, and a corporal, trotting back from the Sanchez place, reported that Munoz and some of his fellows had joined in the search, and already with important result. Captain Turner sent him back with his compliments to the commanding officer. In the presence of Bonner, Bucketts and Strong, the general took the package, something heavy, bundled in the red silk handkerchief Turner had torn from his own brawny throat. A scrap of paper went fluttering to the ground, which the adjutant quickly recovered and handed to his chief, who read aloud in the dim candle light the words: "It might be well to keep this from Harris, at least to-night." Looking a trifle dazed, Archer unrolled the silken folds, and laid on the office table the handsome, silver-mounted Colt revolver of the old calibre 44 model Willett had lost that Sunday night of his perilous adventure up the valley. There it was, inscription and all, every visible chamber still loaded, its murderous leaden bullet showing in the candle light. Archer slowly drew back the hammer. The cylinder slowly revolved. The barrel-chamber swung as slowly into view, black, powder-stained, and--empty. One shot, then, had been fired and very recently. Who could have had it all this time but 'Tonio? Who else could have fired it? CHAPTER XXII.
