there had been any one to observe this solitary traveler, he would have said that the man gave no heed to the beauty of the day. Since he had broken camp his impassive gaze had been fixed for the most part on the ground in front of him. Occasionally he swung his long leg across the rump of the horse and dismounted to stoop down for a closer examination of the hoofprints he was following. They were not recent tracks. He happened to know that they were about three days old. Plain as a printed book was the story they told him.
The horses that had made these tracks had been ridden by men in a desperate hurry. They had walked little and galloped much. Not once had they fallen into the easy Spanish jog-trot used so much in the casual travel of the South-west. The spur of some compelling motive had driven this party at top speed.
Since Dingwell knew the reason for such haste he rode warily. His alert caution suggested the panther. The eye of the man pounced surely upon every bit of cactus or greasewood behind which a possible foe might be hidden. His lean, sun-tanned face was an open letter of recommendation as to his ability to take care of himself in a world that had often glared at him wolfishly. A man in a temper to pick a quarrel would have looked twice at Dave Dingwell before choosing him as the object of it—and then would have passed on to a less competent citizen.
The trail grew stiffer. It circled into a draw down which tumbled a jocund little stream. Trout, it might be safely guessed, lurked here in the riffles and behind the big stones. An ideal camping-ground this, but the rider rejected it apparently without consideration. He passed into the cañon beyond, and so by a long uphill climb came to the higher reaches of the hills.
He rode patiently, without any hurry, without any hesitation. Here again a reader of character might have found something significant in the steadiness of the man. Once on the trail, it would not be easy to shake him off.
By the count of years Dingwell might be in the early forties. Many little wrinkles radiated fanlike from the corners of his eyes. But whatever his age time had not tamed him. In the cock of those same steel-blue eyes was something jaunty, something almost debonair, that carried one back to a youth of care-free rioting in a land of sunshine. Not that Mr. Dingwell was given to futile dissipations. He had the reputation of a responsible ranchman. But it is not to be denied that little devils of mischief at times danced in those orbs.
Into the hills the trail wound across gulches and along the shoulders of elephant humps. It brought him into a country of stunted pines and red sandstone, and so to the summit of a ridge which formed part of the rim of a saucer-shaped basin. He looked down into an open park hedged in on the far side by mountains. Scrubby pines straggled up the slopes from arroyos that cleft the hills. By divers unknown paths these led into the range beyond.
A clump of quaking aspens was the chief landmark in the bed of the park. Though this was the immediate destination of Mr. Dingwell, since the hoofprints he was following plunged straight down toward the grove, yet he took certain precautions before venturing nearer. He made sure that the 45-70 Winchester that lay across the saddle was in working order. Also he kept along the rim of the saucer-shaped park till he came to a break where a creek tumbled down in a white foam through a ravine.
"It's a heap better to be safe than to be sorry," he explained to himself cheerfully. "They call this Lonesome Park, and maybe so it deserves its name to-day. But you never can tell, Dave. We'll make haste slowly if you don't mind."
Along the bank of the creek he descended, letting his sure-footed cowpony pick its own way while he gave strict attention to the scenery. At a bend of the stream he struck again the trail of the riders he had been following and came from there directly to the edge of the aspen clump.
Apparently his precautions were unnecessary. He was alone. There could be no doubt of that. Only the tracks of feet and the ashes of a dead fire showed that within a few days a party had camped here.
Dingwell threw his bridle to the ground and with his rifle tucked under his arm examined the tracks carefully. Sometimes he was down on hands and knees peering at the faint marks of which he was reading the story. Foot by foot he quartered over the sand, entirely circling the grove before he returned to the ashes of the dead fire. Certain facts he had discovered. One was that the party which had camped here had split up and taken to the hills by different trails instead of as a unit. Still another was that so far as he could see there had been no digging in or near the grove.
It was raining more definitely now, so that the distant peaks were hidden in a mist. In the lee of the aspens it was still dry. Dingwell stood there frowning at the ashes of the dead campfire. He had had a theory, and it was not working out quite as he had hoped. For the moment he was at a mental impasse. Part of what had happened he could guess almost as well as if he had been present to see it. Sweeney's posse had given the fugitives a scare at Dry Gap and driven them back into the desert. In the early morning they had tried the hills again and had reached Lonesome Park. But they could not be sure that Sweeney or some one of the posses sent out by the railroad was not close at hand. Somewhere in the range back of them the pursuers were combing the hills, and into those very hills the bandits had to go to disappear in their mountain haunts.
Even before reaching the park Dingwell had guessed the robbers would separate here and strike each for individual safety. But what had they done with the loot? That was the thing that puzzled him.
They had divided the gold here. Or one of them had taken it with him to an appointed rendezvous in the hills. Or they had cached it, One of these three plans had been followed. But which?
Dingwell rubbed the open fingers of one hand slowly through his sunburnt thatch of hair. "Doggone my hide, if it don't look like they took it with them," he murmured. "But that ain't reasonable, Dave. The man in charge of this hold-up knew his business. It was smooth work all the way through. If it hadn't been for bad luck he would have got away with the whole thing fine. They still had the loot with them when they got here. No doubt about that. Well, then! He wouldn't divvy up here, because, if they separated, and any one of them got caught with the gold on him, it would be a give-away. But if they didn't have the dough on them, it would not matter if some of the boys were caught. You can't do anything with a man riding peaceable through the hills looking for strays, no matter how loaded to the guards with suspicions you may be. So they would cache the loot. Wouldn't they? Sure they would if they had any sense. But tell me where, Dave."
His thoughtful eyes had for some moments been resting on something that held them. He stooped and picked up a little chip of sealing-wax. Instantly he knew how it had come here. The gold sacks had been sealed by the express company with wax. At least one of the sacks had been opened here by the robbers.
Did this mean they had divided their treasure here? It might mean that. Or it might mean that before they cached it they had opened one sack to see how much it held. Dingwell clung to the opinion that the latter was the truth, partly because this marched with his hopes and partly because it seemed to him more likely. There would be a big risk in taking their haul with them farther. There was none at all in caching it.
It was odd how that little heap of ashes in the center of the camp-fire drew his eye. Ashes did not arrange themselves that way naturally. Some one had raked these into a pile. Why? And who?
He could not answer those questions offhand. But he had a large bump of curiosity about some things. Otherwise he would not have been where he was that afternoon. With his boot he swept the ashes aside. The ground beneath them was a little higher than it was in the immediate neighborhood. Why should the bandits have built their fire on a small hillock when there was level ground adjacent? There might be a reason underneath that little rise of ground or there might not. Mr. Dingwell got out his long hunting-knife, fell on his knees, and began to dig at the center of the spot where the campfire had been.
The dirt flew. With his left hand he scooped
