 sense of extreme physical nausea overcame him. He reeled, then managed to steady himself. He, too, was invisible to his own eyes. Involuntarily he cried out. No sound came from his lips. He stood there, invisible in an invisible, soundless void.

For what seemed an unending period he occupied himself with endeavoring to obtain the sense of balance. Then, with a great effort, he managed to loosen the cords that bound his right arm to his side. A mighty wrench, and he had slipped them up above his elbow. His right lower arm was free.[64]

He extended it cautiously, and his hand encountered a railing. Instantly he felt more at ease. He began moving slowly around in a widening circle, and discovered that the platform was enclosed. The further side was, however, open, and he began sliding forward, foot by foot, to locate himself. Once his foot slipped over the edge, and he drew back hastily. He felt on the other side, and discovered that he was upon what seemed a plank walk, perhaps a hundred and fifty feet above the ground, with no rail on either side, and some six feet wide.

Very cautiously he shuffled his way along it. It was solid enough, although invisible, but more than once Dick walked perilously close to one edge or the other. At length he went down on his hands and knees, and proceeded, crawling, until his movements were arrested by what was unmistakably a door.

The plank bridge, then, connected the top stories of two buildings, but what the second was, there was no means of knowing. The door was barred on the other side, and did not yield an iota to Dick's cautious pressure. Dick felt the frame. Beyond was glass, reinforced with iron on the outside, the latter metal forming a sort of lattice work. Cautiously Dick began to crawl up the rounded dome.

oot by foot he made his way, clinging to the iron bars, until he felt that he had reached the point of the dome's maximum convexity. He wedged his feet against a bar and rested. Only now was it brought home to him that it would be impossible for him to find his way back to the plank.

A long time must have passed, for, looking out to sea, he could see the squadron now, minute points on the horizon, exuding smudges of smoke. The dirigible was still invisible. The airplanes had either left the tarmac or had been wrapped in the gas-impregnated cloth, for both they and the aviators had vanished.

Suddenly Dick had an odd sensation that the iron was growing warm.

In another moment or two he had no doubt of it. The iron bar he clutched was distinctly warm; it was growing hot. He shifted his grasp to the adjacent bar and even in that moment the heat had increased perceptibly.

Suddenly there came a vibration, a sense of movement. Dick was being swung outward. The whole dome seemed to be dropping into space. He dug his feet and fingers under the hot rods, and felt himself sliding over on his back.

Back—back, till he was lying horizontally in space, and clutching desperately at the iron bar, which was growing hotter every moment.

The sliding movement ceased. It was as if the whole upper section of the glass dome had opened outward. But the heat of the bars was becoming unbearable, and gusts of hot air seemed to be proceeding from within.

Hot or not, Dick's only alternative was to work his way back to the stable portion of the dome, or to frizzle until he dropped through space.

Clinging desperately to the bars, he began working back, reaching from bar to bar with his right hand and dragging his feet, with the clanking chain attached, from bar to bar also.

ow he gained the base of the dome he was never able afterward to understand. The heat had grown intolerable; his hands were blistering. Somehow he reached it. He rested a moment despite the heat. But to find the plank walk was clearly impossible. In another minute he must drop. Better that than to fry there like St. Lawrence on his griddle.

And then, just when he had resigned himself to that last drop, there came an unexpected diversion. Almost beside him a window was hung back. A man looked out. Dick saw one of the workmen in the blue blouses, and, behind him, within the dome, what seemed like an empty room.[65]

Dick was slightly above the man. As his head and shoulders appeared, he let himself go, landing squarely across his back. He slid down his shoulders through the open window into the interior of the dome.

The man, flung against the frame of the window by the shock, uttered a piercing cry. Before he could recover his stand, or take in what had happened to him, Dick had gained his feet and leaped upon him. His right hand closed upon his throat. He bore him to the floor and choked him into insensibility.

CHAPTER XI In the Laboratory

ot until the man's struggles had ceased, and he lay unconscious, panting, and blue in the face, did Dick release him. Then he looked about him.

Save for the workman, he was alone in a rotunda, open to the sky, and, as he had supposed, the whole upper portion of the dome had been flung back, leaving an immense aperture into which the sun was shining, flecking the interior with shafts of light. The temperature, despite the opening of the dome, must have been in excess of a hundred and twenty-five degrees.

There was nothing except an immense central shaft, up which ran a hollow pole of glass, cut off by the invisible paint at the summit of the dome. The inside of this glass pole was glowing with colored fires, and it was from this that the intolerable heat came, though its function Dick could not imagine.

One thing was clear: It was growing hotter each moment. To remain in that rotunda meant death within a brief period of time.

And there was no way out! Dick glared around him, searching the glass walls in vain. No semblance of a stairway or ladder, even. Yet the workman must have entered by some ingress—if only Dick could discover it!

He began running round the interior of the dome in the brilliant sunshine, searching frantically for that ingress. And it was growing hotter! The sweat was pouring down his face beneath the invisible garment.

Dick was vaguely aware that the silence switch had been thrown in the room, for his feet made no sound, but the knowledge was latent in his mind. Two or three times he circumnavigated the interior of the dome, like a rat in a trap.

Then suddenly he saw a section of the flooring rise in a corner, and a workman in a blue blouse appear out of the trap door.

e stood there, his face muscles working as he shouted for his companion, but no sound came from his lips. He looked about him, and saw the unconscious man beside the window. He started in his direction.

With a shout, Dick hurled himself toward him. And he checked himself even as he was about to leap. For he realized that the second workman neither saw nor heard him.

Yet some subconscious impression of danger must have reached his mind, for the workman stopped too, instinctively assuming an attitude of defense. Dick gathered a dozen links of his wrist-chain in his right hand, leaped and struck.

The workman crumpled to the floor, a little thread of blood creeping from his right temple.

It was the thing upon which Dick looked back afterward with less satisfaction than any other, leaving the two unconscious men in that room of death. Yet there was nothing else he could have done. He ran to the trap, and saw a ladder leading down. In a moment he had swung himself through and closed the trap behind him.

The material that lined the walls below must have had almost perfect insulating qualities, for the temperature here was no hotter than in the Bahamas on a hot summer day. Dick[66] scrambled down the ladder and found himself in a machine-shop. Nobody was there, and tools of all sorts were lying about, as well as machinery whose purpose he did not understand. A pair of heavy pliers and a vise were sufficient to rid Dick of his wrist and ankle chains in a minute or two. With a knife he slashed the cords of invisible stuff that bound him. He stood up, cramped, but free.

He picked up an iron bar that was lying loose on a table beside a machine, and advanced to the staircase in one corner of the shop. As he approached it, another workman came running up.

ick stood aside in an embrasure in the wall partly occupied by a machine. The man passed within two feet of him and never saw him. Only then did Dick quite realize that he was actually invisible.

The moment the man had passed him, Dick ran to the staircase. He descended one flight; he was half way down another when a yell of pain and imprecation came to his ears. He knew that voice: it was Luke Evans's!

With three bounds Dick reached the bottom of the stairs. He saw a large room in front of him. No mistaking the nature of this room; it was an ordinary laboratory, fitted out with the greatest elaboration, and divided into two parts by paneling. And sight and sound were on.

In the part nearer Dick three men were grouped about a large dynamo, which was sending out a high, musical note as it spun. Levers and dials were all about it, and above it was the base of the glass tube that Dick had seen above. In the other part were five or six men. Three of them were testing some substance at a table; three more were gathered about old Luke Evans, whose silver chains had been removed and replaced by ropes, which bound his limbs, and also bound him to a heavy chair, which seemed to be affixed to the ground. One of the three had a piece of metal in a pair of long-handled pliers. It was white hot, and a white electric spark that shot to and fro between two terminals close by, showed where it had been heated.

Dick started; he recognized one of the three men as Von Kettler. He moved slowly forward, very softly, his feet making no sound on the fiber matting that covered the floor.

id that feel good, American swine?" asked Von Kettler softly, and Dick saw, with horror, a red weal on the old man's forehead. "Now you are perhaps in a more gracious mood, Professor? The unknown isotope in that black gas of yours—you are disposed to give us the chemical formula?"

"I'll see you in hell first," raved old Luke Evans, writhing in his chair.

Von Kettler turned to the man holding the white-hot metal, and nodded. But at that moment a door behind Evans's chair opened, and Fredegonde Valmy appeared in the entrance. Von Kettler turned hastily, snatched the pliers from the man's hand, and laid the metal in a receptacle.

But the girl had seen the
