"Now, whereabouts did the son of a gun leave it?" asked Backus of himself; "and how far back was it that I got a squint of his track last?" He pulled out a cold lunch, that he had brought along in his pocket, put on his overcoat, and sat down to take a rest and think things over. If Stephens had simply turned off and camped near the trail, he might have missed him by very little. Perhaps Felipe had been able to keep him in sight, and had stuck to him.
He started to take the back track, keeping a sharp watch out for likely places for a rider to turn out on one side or other of the trail. There were plenty of them, but he found no sign in any of those that he examined. And he had the exasperating sense, that trying to hit off a lost trail by moonlight was as futile a job as a man ever undertook. By daylight a master of woodcraft may assure himself that he has not walked over a hoofprint for which he is searching without seeing it, but the best trailer that ever stepped can miss a thing by moonlight that by day would be as plain to him as a printed book.
"A fool's errand," he said to himself, "that's what I'm on. Here I might be comfortably at home and snug in bed, and instead of that I'm lost up here in the sierra away along after midnight, and nary chance of finding what I come out after." He was thoroughly out of temper by this time, and his language was according. "Mine! d----n the mine! I believe the whole thing is a holy fraud, and if anyone ever again catches me out in the dark, on top of a rugged range of hills hunting for a mine that never existed, I'll give him leave to cut me into slices and fry me like so much bacon." He sat down to rest a moment before deciding finally whether to make any further effort, or just chuck and make the best of his way home.
At this moment, faint but distinct, came the sound of a shot fired somewhere in the mountain off to the south. Backus sprang to his feet instantly, shaking himself free from his despondency like a cloak.
"By the jumping Jemini!" he ejaculated, "there they are, I'll wager. Felipe must have managed to stick to the trail. Good for him! I wonder if he's managed to plug him? I'll just take a scout round that way and see if I can spot anything."
