It was a terrible risk. Did he dare take it? He thought of the forest, of the raw night, of what was threatened in the morning.... Yes!

Silently, the manikin clasped the nearest table leg, shinnied up and hauled himself over the top. As he got there his heart leaped. A sharp thumping had come from behind. He dropped to his knees and glanced round; but he immediately rose again, rea.s.sured. It was only the rabbits in their cage, disturbed by the strange figure on the table.

He thanked G.o.d that they--and his tarantulas and other insects--could make no alarming noises.

Garth found a long strand of wire. The panel's control lever, swung to the left, controlled increase; to the right, decrease. Garth's plan was to wind the middle of the wire around it, relay each end around the two supporting posts of the switchboard, and thus have both ends of the wire in his hands when he stood inside the chamber. One end of the wire would enable him to pull the lever over for increase, and the other to pull it back to neutral when the increase was completed, or when Hagendorff arose.

Quickly he started to arrange the wire. Then suddenly his hands dropped and he stared dismayed at the control panel.

The power switch had been removed!

It was Hagendorff's work, of course. He had guarded every angle.

Without that switch, the mechanism was lifeless and literally powerless. It worked on a delicately adjusted and enclosed rheostat; there was nothing that could be subst.i.tuted for it. It would take hours to improvise one in the heart of the apparatus.

The switch, Garth reflected bitterly, was probably concealed somewhere about the giant's body.

He considered the possibility of tying him. He knew where there was a coil of light, pliable wire on the floor; he might be able to loop it over the giant's hands and legs while he slept, tie him securely, and then go through his pockets for the switch. Another hazard! But there was nothing else to do.

Garth lowered himself over the table's edge and slid quietly down the leg. He glanced at the sleeping man, then over across the room to where, beneath another table, the wire was--and his nerves jumped at what he saw there.

From the darkness under the table two spots of greenish fire, close to the floor, held steadily on him.

As he stared, they vanished, to reappear more to the right. With the movement, he glimpsed the outline of a lithe, crouching animal, and knew it to be the cat he and Hagendorff had experimented on earlier that night. It was stalking him in the deliberate manner of its kind!

It came edging around, so as to leap on him from the side. He knew that he represented fair prey to it; that if he tried to run, it would pounce on him from behind. Wearily he tensed his miniature body, standing poised on the b.a.l.l.s of his feet and never dropping his eyes for a moment. He could not repress a grim smile at the ludicrousness of being attacked by an ordinary house-cat, even though it was tiger-sized to him. Though his victory over the weasel, a far deadlier fighter, made him confident he could dispatch it, there was another aspect to the approaching struggle. It would have to be fought in silence. Not four feet away, Hagendorff slept. There lay the overwhelming danger.

Even as these things flashed through his brain, the cat steadily inched nearer on its padded paws. Ghostly starlight framed it now; Garth could see the eager, quivering muscles, the long tail, flat behind, twitching slightly, the rigid, unstirring head and the slowly contracting paws. The terrible suspense of its stalking sc.r.a.ped his nerves. There would be a long pause, then an almost imperceptible hunching forward, with the tail ever twitching; then the same thing again, and over again. It became unbearable. Garth deliberately invited the attack.

He pretended to turn and run, his back towards it. At once he sensed its tensing body, its bunching muscles--then knew that it had sprung.

Whirling, he had a fleeting impression of a supple body in midair, of bristling claws and bared, needlepoint fangs. But he was ready. The weasel had taught him his best weapon, the great weight of his body.

He streaked in beneath the wide-spread paws, shot his hands into the fur of the throat and threw himself against the shock of the animal's suddenly arrested leap.

There was no standing his weight. Over the cat went, its back thudding into the floor, its claws held powerless by the hundred and eighty pounds of hard flesh that straddled it.

The fall had made little noise; but, as Garth tightened the grip of his fingers and bored inward, a dull, steady thumping began to sound.

It was the cat's tail, pounding on the floor!

Desperately he tried to hook a leg over it, but could not reach far enough. It beat like a tom-tom. From above, there came the sound of a huge frame stirring, and the rumble of a sleepy grunt.

In a moment, the t.i.tan would be thoroughly awake.

By the drumming tail alone, Garth realized, his chance of regaining full size was sent glimmering. There was nothing but retreat, now, and a hasty one, if he valued life. Another noise came from the waking Hagendorff. He was sitting up, staring around. Garth jumped to his feet, threw the cat's twitching body beneath the table, and dodged at full speed for the hole whereby he had entered.

Like a mouse he wriggled through, leaped to the ground, scrambled up and made for the forest. He ran with all the speed at his command, and was almost surprised when he reached the black fringe of the forest in safety. In the protecting gloom, he dared to pause and look back.

Hagendorff was not pursuing him. From the sound, he was merely boarding shut the drain hole, to prevent another entrance in that way; then, afterwards, the windows.

Garth was puzzled. "I don't understand it," he said aloud. "Why is he so sure he can get me in the morning? Isn't he afraid I'll leave the island? Why I've _got_ to try to get away, now. It would be death to be here after the dawn!"

He stood there making his plans. They had a rowboat below, powered with an outboard motor. Even in his present size, he might possibly run it, if he could get it started. He would strike down-river for Detroit, and when the gas gave out, the current would carry him on.

Some river boat might pick him up and carry him to friends in the city. His grotesquely dwarfed body would prove his story, and they would bring him back and end Hagendorff's mad dream of fame, and help him to regain his normal size. He could superintend the construction of another machine if the present one was wrecked.

When he started down the trail to the river, he seemed to be walking through a haze. He felt curiously light-headed, and his body was completely numb. The long exposure was telling on him, and there was much more of it to come. He wondered if he could hold out until he reached the mainland.

But his mind cleared of the daze the cold and near-exhaustion had brought it to when at last he came to the beach and realized that again Hagendorff had antic.i.p.ated him. The rowboat was gone! No wonder the giant could afford to wait until daylight.

Garth floundered down to the beach and ran to where the craft usually lay. There was only a groove in the rough, pebbly surface, a groove left by the boat's keel. He followed it up the bank, and twenty yards in found the dinghy chained and locked firmly to a large tree.

The midget's face grew suddenly very haggard as he stood there, staring at what looked like his death sentence. He should have known Hagendorff would secure the boat, he told himself bitterly. It was a cruel blow, and sheer misery of mind and body gripped him as he turned and peered through the darkness of wind-whipped water and sky toward a horizon that was already lightening. Down-river lay Detroit, a friendly, everyday world. It was not far in miles, but it seemed lost to him forever....

Garth took his eyes from that prospect with a wry twist to his mouth.

It chanced that they fell on the painter of the rowboat.

It was a stout Manila cord, some twenty feet in length, and tied tightly to a ring in the bow of the boat. He looked at it dully for a full minute before the idea came to him. Then suddenly the lethargy bred of hopelessness left him. Garth remembered a pocket knife he had left in the boat the day before. He climbed over the side and began to fumble about in the darkness. First he came upon a torn handkerchief which he hastily tied about his loins. Further probing disclosed the knife wedged under a seat in the boat. When he had finally extricated it, he threw the knife over the side and climbed out.

After some minutes of frantic cutting and hacking he severed the rope, and, quickly taking up one of the ends, ran with it further along the bank.

There was still a way of getting off the island. A cold and risky way, but better than waiting miserably for capture. On the bank was a pile of sawn logs, intended for firewood; and a strong rope was in his hands. Much indeed could be done now.

The making of his raft proved a herculean task, a racking and almost impossible one for a man limited by doll-sized hands and a foot-high body. First the logs had to be rolled to the water's edge, six of them. Each was as thick as he was tall, and this first part of his task took him a precious half hour, every minute of which brought nearer the dawn. Ripples like ordinary waves washed up the struggling manikin and left him gasping as he stood braced in the cold water and tugged one log after another out and wound the rope under and over it.

The raft had to be built in water; he would never have been able to drag the whole thing off the beach.

When at last he wearily tied the rope end to the last log, and stuck his knife handy in it, the clouds on the horizon were flushed by the coming sun. But his means of escape was completed; and hanging on the end, he shoved the raft out into the river. Right then he almost lost his life. For when his feet left the sloping bottom, his great weight, out of all proportion to the size of his body, pulled him under, and it was only by virtue of a desperate clutch on the raft that he escaped drowning. Thrashing furiously, he struggled up from the water, and lay, totally blown, on the logs. It was then he first realized that his chance of life was no stronger than the rope which held them together. For swimming was out of the question, and one or two logs would never support his hundred and eighty pounds.

The end which he lay on was well under water, and the waves splashed up between the bobbing logs. The current he was headed for swept down fifty yards offsh.o.r.e, which was a sixth of a mile to the little legs now thrust out behind and making a rhythmic flutter.

He was off the island! Freedom and life were near! Though his teeth were chattering, his fingers crushed by the jarring logs, and his body utterly wretched, he grinned with joy as the stretch between him and the gloomy ma.s.s of the island slowly widened.

Then came the sun. The skies faded from gray into a delicate, cloud-flecked blue; slowly the air warmed, and the surface of the water seemed to calm under it. Though the sun was good on his body, Garth realized night was more friendly to him, for in the growing light his craft was all too conspicuous to the giant who would presently be following his tracks down to the beach. He chided himself for not having thought of camouflaging the raft with leafy branches.

Doggedly, he forced it out.

When at last he felt the pull of the current, he ceased his weary kicking and glanced up into the swiftly advancing dawn. There was a bird soaring through the keen air up there, gliding in easy circles with almost motionless wings. Garth gazed at it somewhat wistfully, envying its freedom and power of flight. And then he shut his eyes. He was very tired....

He must have dozed off for a moment, for he awoke to find himself slipping off. With a sudden jerk he regained his position--and that was what saved his life at that moment. For without warning, while he was nodding, plumed death struck from the skies.

It dropped like a plummet, as was its manner. It had been circling above and judging its swoop, and by rights its curved talons should have arched deep into the unguarded back of the naked figure on the raft. But at the last second the figure moved aside--too late for the hawk to alter its swoop.
