to guess at these qualities of the rider, for they were such things as a child feels more readily than a grown man; but it needed no expert to admire the horse he bestrode. It was a statue in black marble, a steed fit for a Shah of Persia! The stallion stood barely fifteen hands, but to see him was to forget his size. His flanks shimmered like satin in the sun. What promise of power in the smooth, broad hips! Only an Arab poet could run his hand over that shoulder and then speak properly of the matchless curve. Only an Arab could appreciate legs like thin and carefully drawn steel below the knees; or that flow of tail and windy mane; that generous breast with promise of the mighty heart within; that arched neck; that proud head with the pricking ears, wide forehead, and muzzle, as the Sheik said, which might drink from a pint-pot.
A rustling like dried leaves came from among the rocks and the hair rose bristling around the neck of the wolflike dog. With outstretched head he approached the rocks, sniffing, then stopped and turned shining eyes upon his master, who nodded and swung from the saddle. It was a little uncanny, this silent interchange of glances between the beast and the man. The cause of the dog's anxiety was a long rattler which now slid out from beneath a boulder, and giving its harsh warning, coiled, ready to strike. The dog backed away, but instead of growling he looked to the man.
Cowboys frequently practise with their revolvers at snakes, but one of the peculiarities of this rider was that he carried no gun, neither six-shooter nor rifle. He drew out a short knife which might be used to skin a beef or carve meat, though certainly no human being had ever used such a weapon against a five-foot rattler. He stooped and rested both hands on his thighs. His feet were not two paces from the poised head of the snake. As if marvelling at this temerity, the big rattler tucked back his head and sounded the alarm again. In response the cowboy flashed his knife in the sun. Instantly the snake struck but the deadly fangs fell a few inches short of the riding boots. At the same second the man moved. No eye could follow the leap of his hand as it darted down and fastened around the snake just behind the head. The long brown body writhed about his wrist, with rattles clashing. He severed the head deftly and tossed the twisting mass back on the rocks.
Then, as if he had performed the most ordinary act, he rubbed his gloves in the sand, cleansed his knife in a similar manner, and stepped back to his horse. Contrary to the rules of horse-nature, the stallion had not flinched at sight of the snake, but actually advanced a high-headed pace or two with his short ears laid flat on his neck, and a sudden red fury in his eyes. He seemed to watch for an opportunity to help his master. As the man approached after killing the snake the stallion let his ears go forward again and touched his nose against his master's shoulder. When the latter swung into the saddle, the wolf-dog came to his side, reared, and resting his forefeet on the stirrup stared up into the rider's face. The man nodded to him, whereat, as if he understood a spoken word, the dog dropped back and trotted ahead. The rider touched the reins and galloped down the easy slope. The little episode had given the effect of a three-cornered conversation. Yet the man had been as silent as the animals.
In a moment he was lost among the hills, but still his whistling came back, fainter and fainter, until it was merely a thrilling whisper that dwelt in the air but came from no certain direction.
His course lay towards a road which looped whitely across the hills. The road twisted over a low ridge where a house stood among a grove of cottonwoods dense enough and tall enough to break the main force of any wind. On the same road, a thousand yards closer to the rider of the black stallion, was Morgan's place.
2. THE PANTHER
In the ranch house old Joseph Cumberland frowned on the floor as he heard his daughter say: "It isn't right, Dad. I never noticed it before I went away to school, but since I've come back I begin to feel that it's shameful to treat Dan in this way."
Her eyes brightened and she shook her golden head for emphasis. Her father watched her with a faintly quizzical smile and made no reply. The dignity of ownership of many thousand cattle kept the old rancher's shoulders square, and there was an antique gentility about his thin face with its white goatee. He was more like a quaint figure of the seventeenth century than a successful cattleman of the twentieth.
"It is shameful, Dad," she went on, encouraged by his silence, "or you could tell me some reason."
"Some reason for not letting him have a gun?" asked the rancher, still with the quizzical smile.
"Yes, yes!" she said eagerly, "and some reason for treating him in a thousand ways as if he were an irresponsible boy."
"Why, Kate, gal, you have tears in your eyes!"
He drew her onto a stool beside him, holding both her hands, and searched her face with eyes as blue and almost as bright as her own. "How does it come that you're so interested in Dan?"
"Why, Dad, dear," and she avoided his gaze, "I've always been interested in him. Haven't we grown up together?"
"Part ways you have."
"And haven't we been always just like brother and sister?"
"You're talkin' a little more'n sisterly, Kate."
"What do you mean?"
"Ay, ay! What do I mean! And now you're all red. Kate, I got an idea it's nigh onto time to let Dan start on his way."
He could not have found a surer way to drive the crimson from her face and turn it white to the lips.
"Dad!"
"Well, Kate?"
"You wouldn't send Dan away!"
Before he could answer she dropped her head against his shoulder and broke into great sobs. He stroked her head with his calloused, sunburned hand and his eyes filmed with a distant gaze.
"I might have knowed it!" he said over and over again; "I might have knowed it! Hush, my silly gal."
Her sobbing ceased with magic suddenness.
"Then you won't send him away?"
"Listen to me while I talk to you straight," said Joe Cumberland, "and accordin' to the way you take it will depend whether Dan goes or stays. Will you listen?"
"Dear Dad, with all my heart!"
"Humph!" he grunted, "that's just what I don't want. This what I'm goin' to tell you is a queer thing—a mighty lot like a fairy tale, maybe. I've kept it back from you years an' years thinkin' you'd find out the truth about Dan for yourself. But bein' so close to him has made you sort of blind, maybe! No man will criticize his own hoss."
"Go on, tell me what you mean. I won't interrupt."
He was silent for a moment, frowning to gather his thoughts.
"Have you ever seen a mule, Kate?"
"Of course!"
"Maybe you've noticed that a mule is just as strong as a horse— "
"Yes."
"—but their muscles ain't a third as big?"
"Yes, but what on earth—"
"Well, Kate, Dan is built light an' yet
