of him?"
"He came here a while ago an' tried to make a deal with me."
"An' made it!" said Silent ominously.
No gun pointed at him this time, but Hardy jerked his hands once more above his head and cowered against the wall.
"So help me God he didn't, Jim."
"Get your hands down."
He lowered his hands slowly.
"I told him I didn't know nothin' about you."
"What about that train? What about that shipment?"
"It's jest the way I told you, except that it's on the eighteenth instead of the nineteenth."
"I'm goin' to believe you. If you double cross me I'll have your hide. Maybe they'll get me, but there'll be enough of my boys left to get you. You can lay to that. How much did they offer you, Lee? How much am I worth to the little old U.S.A.?"
"I—I—it wasn't the money. I was afraid to stick with my game any longer."
The long rider had already turned towards the door, making no effort to keep his face to the agent. The latter, flushing again, moved his hand towards his hip, but stopped the movement. The last threat of Silent carried a deep conviction with it. He knew that the faith of long riders to each other was an inviolable bond. Accordingly he followed at the heels of the other man into the outside room.
"So long, old timer," he called, slapping Silent on the shoulder, "I'll be seein' you ag'in before long."
Calder's men looked up with curious eyes. Hardy watched Silent swing onto his horse and gallop down the street. Then he went hurriedly back to his office. Once inside he dropped into the big swivel-chair, buried his face in his arms, and wept like a child.
12. PARTNERS
Dust powdered his hat and clothes as Tex Calder trotted his horse north across the hills. His face was a sickly grey, and his black hair might have been an eighteenth century wig, so thoroughly was it disguised. It had been a long ride. Many a long mile wound back behind him, and still the cattle pony, with hanging head, stuck to its task. Now he was drawing out on a highland, and below him stretched the light yellow-green of the willows of the bottom land. He halted his pony and swung a leg over the horn of his saddle. Then he rolled a cigarette, and while he inhaled it in long puffs he scanned the trees narrowly. Miles across, and stretching east and west farther than his eye could reach, extended the willows. Somewhere in that wilderness was the gang of Jim Silent. An army corps might have been easily concealed there.
If he was not utterly discouraged in the beginning of his search, it was merely because the rangers of the hills and plains are taught patience almost as soon as they learn to ride a horse. He surveyed the yellow-green forest calmly. In the west the low hanging sun turned crimson and bulged at the sides into a clumsy ellipse. He started down the slope at the same dog-trot which the pony had kept up all day. Just before he reached the skirts of the trees he brought his horse to a sudden halt and threw back his head. It seemed to him that he heard a faint whistling.
He could not be sure. It was so far off and unlike any whistling he had ever heard before, that he half guessed it to be the movement of a breeze through the willows, but the wind was hardly strong enough to make this sound. For a full five minutes he listened without moving his horse. Then came the thing for which he waited, a phrase of melody undoubtedly from human lips.
What puzzled him most was the nature of the music. As he rode closer to the trees it grew clearer. It was unlike any song he had ever heard. It was a strange improvisation with a touch of both melancholy and savage exultation running through it. Calder found himself nodding in sympathy with the irregular rhythm.
It grew so clear at last that he marked with some accuracy the direction from which it came. If this was Silent's camp, it must be strongly guarded, and he should approach the place more cautiously than he could possibly do on a horse. Accordingly he dismounted, threw the reins over the pony's head, and started on through the willows. The whistling became louder and louder. He moved stealthily from tree to tree, for he had not the least idea when he would run across a guard. The whistling ceased, but the marshal was now so near that he could follow the original direction without much trouble. In a few moments he might distinguish the sound of voices. If there were two or three men in the camp he might be able to surprise them and make his arrest. If the outlaws were many, at least he could lie low near the camp and perhaps learn the plans of the gang. He worked his way forward more and more carefully. At one place he thought a shadowy figure slipped through the brush a short distance away. He poised his gun, but lowered it again after a moment's thought. It must have been a stir of shadows. No human being could move so swiftly or so noiselessly.
Nevertheless the sight gave him such a start that he proceeded with even greater caution. He was crouched close to the ground. Every inch of it he scanned carefully before he set down a foot, fearful of the cracking of a fallen twig. Like most men when they hunt, he began to feel that something followed him. He tried to argue the thought out of his brain, but it persisted, and grew stronger. Half a dozen times he whirled suddenly with his revolver poised. At last he heard a stamp which could come from nothing but the hoof of a horse. The sound dispelled his fears. In another moment he would be in sight of the camp.
"Do you figger you'll find it?" asked a quiet voice behind him.
He turned and looked into the steady muzzle of a Colt. Behind that revolver was a thin, handsome face with a lock of jet black hair falling over the forehead. Calder knew men, and now he felt a strange absence of any desire to attempt a gun-play.
"I was just taking a stroll through the willows," he said, with a mighty attempt at carelessness.
"Oh," said the other. "It appeared to me you was sort of huntin' for something. You was headed straight for my hoss."
Calder strove to find some way out. He could not. There was no waver in the hand that held that black gun. The brown eyes were decidedly discouraging to any attempt at a surprise. He felt helpless for the first time in his career.
"Go over to him, Bart," said the gentle voice of the stranger. "Stand fast!"
The last two words, directed to Calder, came with a metallic hardness, for the marshal started as a great black dog slipped from behind a tree and slunk towards him. This was the shadow which moved more swiftly and noiselessly than a human being.
"Keep back that damned wolf," he said desperately.
"He ain't goin' to hurt you," said the calm voice. "Jest toss your gun to the ground."
There was nothing else for it. Calder dropped his weapon with the butt towards Whistling Dan.
"Bring it here, Bart," said the latter.
The big animal lowered his head, still keeping his green eyes upon Calder, took up the revolver in his white fangs, and glided back to his master.
"Jest turn your back to me, an' keep your hands clear of your body," said Dan.
Calder obeyed, sweating with shame. He felt a hand pat his pockets lightly in search for a hidden weapon, and then, with his head slightly
