Fresh horses were saddled, and Lennon was tied on as before. His last hope of escape went glimmering. He realized that he had missed his one chance when the party first reached the main trail, coming out of Dead Hole.

To have attacked even then would have been a desperate undertaking—one man against five. But he would have had at least a fighting chance. Now he was unarmed and bound, unable even to shift in the saddle.

Slade set a hot pace that fast ate up the hard miles of the return trail. But no pony could carry his massive weight as had the horse. Before the main caÑon was reached, his mount began to flag. Only the most merciless of rowelling could goad the jaded beast out of a jog except for short spurts. In the descent to the caÑon the pony began to stumble badly. But Slade held him up with an iron grip on the jaw-breaking Spanish ring-bit.

The smooth caÑon bed was only a few yards below when, at the last sharp twist in the descent, the still air vibrated with a sibilant rattle. Slade's pony snorted and jumped sideways, leaving Lennon a clear view of the big diamond-back rattlesnake that lay coiled in the middle of the trail. The gaping jaws of the angry snake and the peculiar billowing of its body so fixed Lennon's gaze that he only half glimpsed the final stumble of Slade's pony.

Unable to keep his footing among the loose stones of the side slope, the exhausted animal plunged headlong. Slade managed to fling himself clear, but fell prone on the sharp-edged stones. His nose was skinned and one cheek gashed. He bounded up, fairly beside himself with rage, and began to kick the head of the fallen pony.

The luckless beast struggled to rise, got half to his feet, screamed, and fell over. Something about his hindquarters had been wrenched or torn or broken. Slade swore furiously and jerked out his revolver to fire repeatedly into the body of the struggling beast. The fourth shot was through the head.

At the sudden stilling of his victim's struggles, the trader's half insane rage cooled from its mad heat without losing any of its virulence. One of the Navahos had dismounted and run forward to stone the rattlesnake. Slade uttered a guttural hissing command. Instead of crushing the snake, the Indian teased it with the butt of his leather quirt.

The reptile lashed out in a vicious stroke. An instant later the Navaho straightened up with his hand gripped about the snake's neck close behind the deadly triangular head. He gave no heed to its five-foot body writhing and coiling about his bare arm.

Slade swung up into the path and looked from the new prisoner to Lennon with a glint in his pale eyes as malignant as the cold glare of the snake.

"You're one of these here science sharps," he jeered. "We'll have you test out if a Gila monster bite fixes a man against rattler poison."

"Rather a costly experiment for you if I prove not to be immune," rallied Lennon. "You must have a keen interest in science so to risk your ten thousand."

"Mebbe. It ain't much of a gamble, though. I stand to rake in twenty thousand if I win, and you ain't liable to let it go as far as the bite."

"Twenty thousand?" questioned Lennon. "If you take Cochise in on this blackmailing scheme, you will have to divide the proceeds with him. Why not keep your bargain and earn your half of the bonus without this risk of losing all?"

The trader's eyes narrowed in crafty calculation. He looked about at the snake and then down at the slaughtered horse. A sudden grin twisted his coarse mouth.

"You're right, son," he chuckled. "Why split the twenty with a dam' Apache? Ain't time now to make the Hole 'fore dark, anyhow—and here's our rawhide. We'll try out that science experiment right here."

He signed for the man with the snake to go on down into the caÑon bed. The other Indians were already unsaddling the dead burro. Slade muttered a command to them in the thick indistinct intonations of their language. They at once started to flay the pony.

Slade led Lennon's mount down where the snake holder had halted beside a sangre de dragon tree. One of the Indians followed and began to cut stakes from the tree. The sap of the tree was as red as blood and so astringent that when Slade dabbed a little on his cheek the wound at once ceased to bleed.

The flayers soon came with the limp rawhide. Slade turned along the caÑon to a spot where the rays of the low western sun still slanted down between the cliffs. He spoke again in the Navaho tongue. The Indians drove a stake firmly into the sand and tied the rattlesnake to it with a three-foot thong cut from the pony skin.

Lennon was now pulled from his pony and stretched out, face down, just beyond reach of the snake. Regardless of the bandage on his hand, his arms were jerked out sideways and fastened with yard-long thongs to stakes driven at right angles to a point a foot or so in front of his head. From stakes set on the opposite side of the snake several lines cut from the raw pony hide were flung across past the snake and bound to Lennon's arms at the shoulder.

By hauling on the lines from ahead, the Indians dragged Lennon an inch at a time toward the snake. He heard the sharp ominous rattle, and twisted his head up out of the sand to face the danger. The snake had coiled in front of the first stake. Though its venomous head was drawn back, the long curved fangs of the gaping jaws were less than three feet before Lennon's eyes.

Even as he looked up, the reptile shot forward straight at his face. He involuntarily blinked. In the same instant a drop of fluid spattered against his closed eyelid and he heard a soft thud in the sand close before his chin. A puff of dust whiffed up into his nostrils. It clotted the dew-like drop of liquid on his eyelid.

He opened his eyes in a wide stare. The head of the big rattlesnake lay flat on the sand, less than eight inches before his face. It had lashed out to the full length of the thong. Had the thong broken, or even had its loop about the reptile's neck slipped, the poison-dripping fangs must have lashed Lennon's face.

Intense as were the heat and dryness of the caÑon bed, Lennon suddenly felt his skin bathed in clammy sweat. For the first time in his life he knew terror. He glared into the cold, malignant eyes of the snake and saw death, certain and horrible. Panic seized him. He writhed and dug his fingers and boot toes into the sand in a frantic attempt to work himself back away from the hideous forward-straining reptile.

The desperate struggle was utterly futile. The lines ahead had been stretched taut and knotted fast to their stakes. With his arms outstretched he could get very little purchase for thrusting himself back against the elastic pull of the rawhide ropes.

But he was no coward. Realization of his helplessness brought him the resignation of despair. With resignation came a stilling of his wild panic. Frantic terror gave way to reasoning thought.

Had his torturer been Cochise, there might have been no room for hope. But Slade was a white man. He might prefer gold to the lust of torture. The death of his victim would mean the loss of the ransom money. Lennon's tense nerves and rigid muscles relaxed. He allowed his upward—and backward-strained head to sink down until one cheek rested upon the hot sand. The change of position brought the top of his head very close to the snake. But he trusted to Slade's avarice to see that he escaped the fangs.

Slade and the Indians had been gloating upon the struggles and terror of their victim. At Lennon's quieting down the trader burst into a derisive laugh.

"Sort of wilted a'ready, huh?" he jeered. "Well, you're wise to take a rest while you still got time. Rawhide shrinks a whole lot when it gits to drying. Only question is how much slower the rattler's whang strap'll shorten up than your lines."

For the first time a clear perception of the real devilishness of the torture flashed into Lennon's abnormally active mind. He was to lie outstretched through the long hours, without food or water, while the shrinking rawhide dragged him with frightful slowness closer and closer to those fangs of death.

The thong of the snake also would be contracting. But it was much the shorter, and therefore would shrink less. The uncertainty of how fast and how much the different fastenings would contract doubled the torturing knowledge that the shrinking must inevitably pull him within reach of the snake.

Physical agony would then soon be added to the mental anguish of dread. For, once the snake's horny snout grazed the top of his head, he would be forced to keep his head raised, on penalty of being pierced by the fangs if he should seek to rest.

Then was when Slade no doubt felt certain that the overstrained nerves of his victim would give way. Lennon foresaw that if worse came to worst, he must agree to terms. After holding up his head as long as his strength lasted, he would be forced to yield. Why not yield at once and save all the torture?

As he asked himself the question, a grateful shadow swept down the caÑon. The sun was setting. Lennon reconsidered his half-formed decision. During the night the rawhide might continue to shrink a little in the dry air, but the darkness and chill would quiet the snake. It would lie still until sunrise. Time enough to yield when yielding should become inevitable!

"If you'll pardon me, Slade," he said, "I believe I'll take a nap. Good night. Pleasant dreams."

Slade started to curse but ended in a derisive laugh.

"Think you'll four-flush, huh? Well, we'll see after sun-up."

He turned his back on the prisoner and walked over to where the old Navaho was starting a fire for the inevitable flapjacks, bacon, and coffee. The thought of food nauseated Lennon. But he would have given a thousand dollars for one of the canteens of water. Regardless of a hiss from the half-strangled snake, he laid his other cheek over on the cooling sand.

After a time Slade came with a blazing stick for torch to wish him a mocking good night. Lennon smiled back at him with a show of confidence. The trader cursed but soon went off to roll in his blankets. This proved Lennon's surmise that the real test would not come before morning.

He lay for a long time wide-eyed, forcing himself to consider in detail every aspect of the situation and to calculate his chances. Beyond question, Slade intended to murder him. But there was first the ransom money to be secured. Would he wait for it, as in the case of the cowman whom Elsie had told about? Or might he not fall into a rage and destroy his victim as he had killed the pony?

If he could keep his temper, the probabilities were that he would prolong the torture until he had gained his end. After that might come a short respite for the victim.

Lennon next recalled all he knew about snakes and their poison glands. After that he closed his eyes and relaxed both mentally and physically. The cool of nightfall had somewhat eased his thirst and the ache from the strain of the rawhide lines on his shoulders. He dozed off to sleep.

He was so far spent and his last thought so calm that he slept soundly all night. But the chill damp of dewfall roused him at the first graying of dawn. To the shivering of his cramped body from the cold was soon added a shudder of fear and loathing. Against his head, just above the forehead, was pressed a cold hard object—the snout of the rattlesnake.

But the reptile was too torpid from the cold to strike. After a time the slight moistening of the rawhide by the dew enabled Lennon to force himself back nearly an inch. This was at sunrise. Slade came to gloat at his struggle.

"Go it," he mocked. "Wiggle while you can. Both them lines and the rattler'll git busy soon's the sun hets up a bit. Excuse me while I feed. I'll git back in time for the fun."

The breakfast fire was beside a patch of thorn scrub several yards away. Lennon watched until his enemy had sat down on the sand opposite the Navahos. He then lifted his head.

The first rays of the sun had begun to warm the snake. At Lennon's movement it stirred sluggishly. The dull eyes began to brighten with the glare of returning life and anger. Lennon dropped his head forward.

Enraged by the feigned attack, the snake struck. The long fangs came so near their mark that Lennon felt them or the snout pass through his hair. Spurts of venom from the overcharged poison glands sprayed in against his scalp.

For the second time since being pegged out Lennon felt his skin go clammy with cold sweat. His flesh crept with horror. Death had grazed him by a fraction of an inch. Another stroke might break or loosen the snake's bond. Yet he nerved himself again and shook his head from side to side.

The movement roused the snake to fury. It lashed out in stroke after stroke. But the very excess of the reptile's anger quickly exhausted its strength. The hideous head flattened down on the sand.

A sideward glance told Lennon that his deadly play had not been heeded by Slade and the Navahos. But he knew he had no time to spare. He filled his parched mouth with sand and raised his head. The snake did not move.

Lennon blew sand into the glaring eyes of the rattler. The jaws gaped angrily. He blew all the remaining sand in between the high-curved fangs. The snake struck viciously and sank down, inert. A film closed over the sand-filled eyes.

By pulling himself forward, Lennon gained a little relaxing of the thongs that held his arms outstretched. He drew up his knees and flung his body up and forward. From a height of several inches his breast came down squarely upon the head of the snake, with all the weight of his body in the blow.

When Slade rushed cursing from the fire, Lennon lay in what appeared to be a swoon, with the body of the rattlesnake writhing about his head. At the angry bellow of the trader the Indians came running to slash Lennon's bonds and jerk him away from the snake.

Slade ripped out an astounded oath.

"He's beaten the game!" he cried.

The head of the reptile had been crushed.
