Mysterious little golden rock! What secrets are there, down beyond the vanishing point in the realm of the infinitely small! Our human longings go to Alan and to Glora.

But sometimes we are swept by the greater viewpoint. Awed by the mysteries of nature, we realize how very small and unimportant we are in the vast scheme of things. We envisage the infinite reaches of astronomical s.p.a.ce overhead. Realms of largeness unfathomable. And at our feet, everywhere, are myriad entrances into the infinitely small.

With ourselves in between--with our fatuous human consciousness that we are of some importance to it all!

Truly there are more things in Heaven and Earth than are dreamed of in our philosophy!

INVISIBLE EYES

An invisible eye that can see in the dark and detect the light of a ship two miles away on a black foggy night was introduced to newspaper men recently by its inventor, John Baird of television fame. He calls the invention "Noctovisor."

It looks like a large camera and can be mounted on a ship or airplane.

It was announced that it would soon be tried on trans-Atlantic liners.

For the demonstration it was mounted in the garden of Baird's cottage, overlooking the twinkling lights of Dorking. In the dark beyond those lights an automobile headlight three miles away pointed toward the cottage.

At a signal from the inventor a sheet of ebonite, as a subst.i.tute for a supposed fog, two miles thick, was placed in front of the headlight.

Not a glimmer was then visible to the human eye, but it appeared on the noctovisor screen as a bright red disc. It was supposed to have particular value in permitting a navigator in a fog to tell the exact direction of a beacon and to estimate roughly its distance.

The device is a combination of camera lens, television transmitter and television receiver. The lens throws a distant image on the exploring disc of the transmitter, through which it acts on a photo-electric cell sensitive to invisible infra-red rays. The receiver amplifies it for the observer.

MOON ROCKETS

Seventeen years of experimenting on a rocket designed by Prof. Albert H. G.o.ddard of Clark University, to shriek its way from the earth to the moon, came to a glorious climax recently in an isolated and closely guarded section of Worcester when the rocket tore its flaming way through the air for a quarter-mile with a roar heard for a distance of two miles.

Prof. G.o.ddard said the rocket was shot out of its cradle, careened through the air a ma.s.s of flame, and landed about where it was directed to land, beyond the Auburn town line. Test of a new propellant was the object of his demonstration, Prof. G.o.ddard said.

Two or three times a week a small rocket goes up into the air a short distance, not enough to attract great attention. But the latest was a nine-foot rocket, shot out of a forty-foot tower. Near the tower is a safety post built of stone, with slits for peepholes. The experimental party stepped into the safety zone when the rocket was started.

The forty-foot tower is built much like an oil well derrick. Inside it are two steel rails to fill grooves in the rocket. These guide the rocket much as rifling in a gun barrel guides a bullet. Prof. G.o.ddard, when teaching at Princeton in 1912, evolved the idea of shooting a rocket to the moon by means of successive charges of explosive much as the new German rocket motor racers are powered. In this most recent experiment he used a new powder mixture.

Prof. G.o.ddard issued a statement after the demonstration, which said:

"My test was one of a series of experiments with rockets using an entirely new propellant. There was no attempt to reach the moon or anything of such a spectacular nature. The rocket is normally noisy, possibly enough to attract considerable attention. The test was thoroughly satisfactory, nothing exploded in the air, and there was no damage except possibly that incidental to landing."

Terrors Unseen

_By Harl Vincent_

[Ill.u.s.tration: _"Eddie!" Lisa screamed suddenly. "Look out!"_]

[Sidenote: One after another the invisible robots escape Shelton's control--and their trail leads straight to the gangster chief Cadorna.]

Something about the lonely figure of the girl caused Edward Vail to bring his car to a sudden stop at the side of the road. When first he had glimpsed her off there on that narrow strip of rock-bound coast he was mildly surprised, for it was a desolate spot and seldom frequented by bathers so late in the season. Now he was aroused to startled attention by the unnatural posture of the slender body that had just been erect and outlined sharply against the graying September sky. He switched off the ignition and sprang to the ground.

Bent backward and twisted into the att.i.tude of a contortionist, the little figure in the crimson bathing suit was a thing at which to marvel. No human being could maintain that position without falling, yet the girl did not fall to the jagged stones that lay beneath her.

She was rigid, straining. Then suddenly her arm waved wildly and she screamed, a wild gasping cry that died in her throat on a note of despairing terror. It seemed that she struggled furiously with an unseen power for one horrible instant. Then the tortured body lurched violently and collapsed in a pitiful quivering heap among the stones.

Eddie Vail was running now, miraculously picking his way over the treacherous footing. The girl had fainted, no doubt of that, and something was seriously wrong with her.

A mysterious mechanical something whizzed past; something that buzzed like a thousand hornets and slithered over the rocks in a series of metallic clanks. Then it was gone--or so it seemed in the confusion of Eddie's mind; but he had seen nothing. Probably a fantasy of his overworked brain, or only the surf breaking against the sea wall. He turned his attention to the girl.

She was moaning and tossing her head, returning painfully to consciousness. He straightened her limbs and placed his folded coat under the restless head, noting with alarm that vicious red welts marred the whiteness of her arms and shoulders. It was as if she had been beaten cruelly; those marks could never have resulted from her fall. Poor kid. Subject to fits of some sort, he presumed. She was a good looker, too, and no mistake. He smoothed back the rumpled ma.s.s of golden hair and studied her features. They were vaguely familiar.

Then she opened her eyes. Stark terror looked out from their ultra-marine depths, and her lips quivered as if she were about to cry. He raised her to a more comfortable position and supported her with an encircling arm. She did cry a little, like a frightened child.

Then, with startling abruptness, she sprang to her feet.

"Where is it?" she demanded.

"Where's what?" Eddie was on his feet, peering in all directions. He remembered the queer sounds he had heard or imagined.

"I--I don't know." The girl pa.s.sed a trembling hand before her eyes as if to wipe away some horrifying vision. "Perhaps it's my imagination, but I felt--it was just as real--one of father's iron monsters.

Beating me; bending me. I'd have snapped in a moment. But nothing was there. I--I'm afraid...."

Eddie caught her as she swayed on her feet. "There now," he said soothingly, "you're all right, Miss Shelton. It's gone now, whatever it was." Iron monsters! In a flash it had come to him that this girl he held in his arms was Lina Shelton, daughter of the robot wizard. No wonder she was afflicted with hallucinations! But those bruises were real, as was the forcible twisting of her lithe young body. And he _had_ heard something.

"You know me?" The girl was calmer now and faced him with a surprised look.

"Yes, Miss Shelton. At least I recognize you from the pictures.

Society page, you know. And I'm Edward Vail--Eddie for short--on vacation and at your service."

The girl smiled wanly. "You know of father's break with Universal Electric? Of his private experiments?"

"I heard of the sc.r.a.p and of how he walked out on the outfit, but nothing further." Eddie thought grimly of how nearly he had come to losing his own job when David Shelton broke relations with his employers. He had been too enthusiastic in support of some of the older man's claims.

"It's been terrible," the girl whispered. She clung nervously to his arm as he picked the way back to the road. "The loneliness, and all.

No servants will stay out here now, and father spends all of his time in the laboratory. Then--this fear of the mechanical men--they haunt me. I--I guess they've got me a little goofy."

Eddie laughed rea.s.suringly. "Perhaps," he suggested, "you will let me help you. Your father, I believe, will remember me, and I'll be very glad to--"

"No, no!" The girl seemed frightened at the thought. "I'm sure he wouldn't welcome you. He's changed greatly of late and is suspicious of everyone, even keeping things from me. But it's awfully nice of you to offer your a.s.sistance, and you've been a perfect peach to take care of me this way. I--I'd better go now."

They had reached the road and Eddie looked uncertainly at his roadster. He hated to think of leaving the girl in this lonely spot.

She was obviously in a state of extreme nervous tension and, to him, seemed pathetically helpless, and afraid.

"That the house?" he asked, pointing in the direction of the gloomy old mansion whose dilapidated gables were barely visible over the tree tops.

"Yes." The girl shivered and drew closer to him.

The ensuing silence was broken by the slam of a door. His car! Eddie looked toward it in amazement; he was hearing things again. The springs sagged on the driver's side as under the weight of a very heavy occupant, but the seat was empty. Then came the whine of the starter and the motor purred into life. The gears clashed sickeningly and the car was jerked into the road with a violence that should have stripped the differential. He pulled the girl aside just as it roared past and disappeared around the bend in a cloud of dust. The sound of the exhaust died away rapidly and left them staring into each other's eyes in awed silence.
