In the meantime Powell and Limber were riding down the caÑon, immersed in deep thought until Limber said, "Thar was fresh lion tracks leadin' into that cave."

Powell jerked about, "Good Lord!" he ejaculated, realizing what it would have meant had the brute been there when the woman and child sought the place of refuge.

"I told Glendon and Juan, and they're layin' for it, and Juan'll tell Mrs. Glendon to keep away from the cave. He won't forget it."

"Well," Powell commented, "I'm glad you told the Mexican. That fellow Glendon thinks of no one but himself. I was watching the child when his father came on the porch, and I'd hate to have any child or animal look at me with such abject fear. It made me sick with fury. How can that woman stand such a life!"

"Glen really does think a heap of her, in his own way," Limber replied slowly, "But when he gets the smell of the cork of a whiskey bottle, he goes plum loco. That's what made the row between him and his folks back East. His father has heaps of money, but won't have nothin' to do with Glen. Leastways, that's what Glen tole me hisself, onct. He said today that he's goin' to pull up stakes as soon as he kin fix it to move, and take his fambly where the Apaches can't run 'em like they done today."

"I'll give him credit for some decent instincts when he moves them to a half-civilized place; but I wouldn't take his word for anything. He's a natural liar, I think. I'm sorry for that wife of his, and for the child."

"She's one of the finest women that ever drawed breath," answered Limber. "She's stood a lot, and she'll stand a heap more."

Conversation ceased until the cowboy pointed to a high peak.

"See that peak up yonder? An ol' fellow lived thar fifteen years prospectin' for gold. Stayed all alone. He was always cocksure he was goin' to find a big mine someday. Some one called him Monty Cristy, and the name stuck to him like a cockle-burr in a horse's mane. One day I was deer-huntin' and run into his camp. He had a dugout in the side of the mountain and a tunnel whar he'd been prospectin'. I went into the tunnel to look at the ore, and found him sittin' thar against the side wall. His pick was across his knees and a piece of ore in his hand, but he had been dead over a week. I buried him up thar."

"Was the mine ever developed?"

"Twarn't nothin' to develope. The bit of rock in his hand was like all the stuff on the dump outside the tunnel. Plum worthless. Chock full of iron pyrites—not worth a damn. 'Fools' Gold' is what the miners calls it."

The cowboy leaned over and petted his pony's neck gently, then straightened up in the saddle and went on; "I've often wondered whether ol' Monty knowed at the last that it was only 'Fools' Gold.' Thar's a heap of people besides ol' Monty that keeps on diggin', hopin' for a strike and gettin' nothin' but 'Fools' Gold.' Tain't no use talkin' to them. It's the lucky ones what don't find out the truth, after they've put in the best of their lives workin' on a false lead."

Powell's thoughts went back to the woman at the Circle Cross, and he answered soberly, "You are right, Limber."

A number of buzzards circled in the caÑon a short distance ahead of them, but not directly on the trail. Limber called the doctor's attention to them, and added, "We'd better go over and see what it is that interests them. Maybe only a dead cow; but when the Indians is out, you never know what you're running into. You learn not to pass anythin' by when you find buzzards."

They left the trail, worked through the dense underbrush that was matted with dead grass and other debris from past heavy floods. Buzzards flew up thickly at their approach. Then they sat looking down at a grey horse huddled in the rocks. Saddle and bridle were gone. A few feet away was the body of an old man, his white hair clotted with blood from a bullet wound in the left temple; his sightless grey eyes upturned to the blue skies, as though in mute questioning.

"God!" ejaculated Limber, as he leaped from his horse. "It's ol' Doctor King! Damn them Apaches!"

Powell's shock was not less than the cowboy's, and he knelt beside the body of the man whom he had hoped to work with at the Springs. He did not think of the annihilation of his own plans, but the things he had heard of the kindly old man. Death had been instantaneous. The bullet had entered the left temple, ranged downward and out behind the right ear. The two men looked at each other, then Powell's eyes went up to the broken side of the caÑon. From back of one of those rocks had sped the messenger of death, with no warning to the old doctor who was on his errand of mercy to a little Mexican baby.

"Why didn't the Indians take the horse?" was Powell's question.

"Because it's grey. They ain't got no use for a grey or white horse, specially when they're out for trouble."

Limber studied the ground about the horse and its dead owner.

"Too rocky to show any trail," he commented at last.

"He's been dead over night," Powell asserted as he finished examining the body.

"The Apaches have been hangin' about for several nights in the Graham range. Thar's two bunches. I seen 'em signalling three nights ago right back of Fort Grant where the soldiers couldn't catch sight of their fires. They keep lookouts on the high peaks and hold a blanket in front of the fire. Beats a telegraph office. Thar ain't nothin' smarter 'n an Apache, unless it's two Apaches. You can't trust one unless he's dead. Chances is that the two bunches figure to come together at Point of Mountains, seven miles north of Willcox. Then when it's dark they'll jump across the valley to Cochise Stronghold and work into Mexico."

"But, the soldiers could head them off," Powell interposed.

Limber snorted. "Sounds that way all right. But, if you jest look at these mountains and caÑons, you'll pretty soon see that the soldiers has jest as much chanct against them Apaches as an elephant would have if you set him in a hayfield to kill a flea by trompin' on it. When they're tired of killin' people and want a vacation and no hard work, they come in and give themselves up and go home to the Reservation."

"There's nothing to be done here now, except to notify the proper authorities at Willcox, I suppose," Powell resumed. "We found him—but it's a different ending from the way we thought."

Limber unstrapped a Navajo blanket from the back of his saddle, and together they wrapped the stiffened form of the old doctor.

"Thar's heaps of people goin' to miss him," the cowpuncher said slowly, as they stood looking down. "Nobody ever called him that he didn't go, rain or shine. He never took one cent for what he done. Jest tol' 'em to feed him an' his ol' grey horse and that was all the pay he wanted. He was sure a good man;" both heads were uncovered in silent homage.

"I'll stay here," continued Limber, "if you'll ride back to Glendon's and get his spring wagon, so we kin take the body to Willcox. It'll be hard gettin' the wagon in the caÑon, but I guess we kin make it. We'll lead our ponies behind the wagon."

Powell was already mounting his horse, as Limber added, "'Twon't take a Coroner's jury long to bring in a verdict. I'm doggone glad, though, we ain't a packin' Mrs. Glendon and Donnie along with Doctor King. They sure had a close call this mornin'. If Geronimo hadn't been in a hurry to get across to that other bunch, they'd sure trailed Mrs. Glendon to that cave."

"It is no place for any woman to live," Powell's voice vibrated with indignation. "I can't understand how any man could bring a woman like her to such surroundings. I'm glad he intends to move his family away. Any place would be better than this, for her."

Limber watched his companion ride off, then busied himself with a second examination of the ground in the vicinity of the dead man and horse. Satisfied at last that he had overlooked no trace, he dropped on a boulder and rolled a cigarette, but as he shook the tobacco from the sack into the brown paper, a portion of it fell to the ground unnoticed. Limber was staring into space, an expression of doubt lurking in his grey eyes.

"Derned if I kin understand why they took so much trouble hidin' their trail, Peanut," he spoke to the little pinto pony at his side. "The main bunch must of rid higher up and one of 'em come down for the bridle and saddle after King was shot; but, thar ain't a moccasin or any other track nowhars. It beats me."

When Powell returned he was accompanied by Glendon, who climbed into the driver's seat and picked up the reins after they placed King's body in the wagon. Limber, leading Powell's pony, followed the wagon, mounted on Peanut. The vehicle bumped and jerked over large rocks of a trail that never before had been traversed by wagon wheels.

Powell was not inclined to talk, but Glendon forced conversation, though it savoured of a monologue.

"King told us he had no one belonging to him," Glendon's voice broke the silence of the caÑon, while the team headed for the Circle Cross. "Katherine said you expected to form a partnership with him and establish a sanitarium at the Springs. I suppose his death will alter your plans. All this part of the country, you know, is unsurveyed ground and title held by possession only. I'd have bought the Springs myself if there had been a regular title. Hesitated at it because I only could acquire Squatter's Rights, you know. However, I took the matter up recently with my father, and am now waiting his reply. I don't understand why King didn't let you know I was figuring on it. Did he give you any option?"

"No;" answered the Doctor, wondering at the statement which conflicted with what Limber had just said regarding Glendon's plans to leave the caÑon. Then he recalled that Traynor had asserted King would not sell to any one except a physician who would co-operate with him in his plans. He knew the man beside him was lying for some reason, but what that reason was, Powell could not decide. "I have not even broached the matter to Doctor King. I came over today to look at the place and if it suited me, to make a proposition to him. I never met him and I don't believe he ever heard of me."

"Of course," Glendon went on, as Powell stopped abruptly wondering if Glendon had no sense of decency to keep talking while the dead man lay in the wagon they were driving, "I had no written agreement with King. Out here, a verbal contract is all we ask of a man. So I ought to have prior right because of our understanding. I don't suppose he made any will, as he had no heirs, and could not will the Springs, anyway, without a legal title to it himself. In that case, the estate would revert to the Territory. A Government Patent would have made less complication."

He glanced furtively at Powell, who made no reply, as they had reached the corral of the Circle Cross. Katherine Glendon stood on the porch, her eyes blinded with tears, her lips quivering.

Glendon climbed heavily from the driver's seat, and Powell saw that his steps were uncertain. Limber tied his pony, Peanut, and the doctor's horse to the back axle of the wagon. A few quiet words were spoken by the two men to Mrs. Glendon, then they went on their way with their tragic burden, and each man was busy with his own thoughts.

It was past sunset when they reached Willcox. After reporting the tragedy and turning the body over to the authorities, there was nothing more they could do, and Powell went to the Willcox Hotel where he obtained a room. Limber parted from him at the door.

"I guess I'd better hunt up the boys and see how things is goin' along with the cattle."

Though neither spoke of it, the uppermost thoughts in the minds of the two men was the woman at the Circle Cross, alone with a man whose indifference to her danger had almost cost her life and that of her boy's.

Back in the lonely caÑon a coyote skulked past the empty house at the Hot Springs. Further down the road a woman stood at the door of her home staring into the darkness.

When she had made her final visit to see if Donnie were all right for the night, and leaned over to press a kiss on the child's cheek, something slipped from his relaxed hand. Wondering which of his toys he had smuggled to bed with him, she stooped and saw the pen-knife that old Doctor King had treasured through his long, lonely years. A wave of realization overwhelmed her. There would be no more visits from this loyal old friend, now. The future loomed ahead of her as black as the night that wrapped the caÑon.
