The men of Cleric were surrounding Jaska now, protecting her with their lives against the tentacles of that lone Aircar splashed with crimson--and all were flying a losing race with the Earth, which was still being forced outward from the Moon!

From An Amber Block

_By Tom Curry_

"These should prove especially valuable and interesting without a doubt, Marable," said the tall, slightly stooped man. He waved a long hand toward the ma.s.ses of yellow brown which filled the floor of the s.p.a.cious workrooms, towering almost to the skylights, high above their heads.

[Sidenote: A giant amber block at last gives up its living, ravenous prey.]

"Is that coal in the biggest one with the dark center?" asked an attractive young woman who stood beside the elder of the men.

"I am inclined to believe it will prove to be some sort of black liquid," said Marable, a big man of thirty-five.

There were other people about the immense rooms, the laboratories of the famous Museum of Natural History. Light streamed in from the skylights and windows; fossils of all kinds, some immense in size, were distributed about. Skilled specialists were chipping away at matrices other artists were reconstructing, doing a thousand things necessary to the work.

A hum of low talking, accompanied by the irregular tapping of chisels on stone, came to their ears, though they took no heed of this, since they worked here day after day, and it was but the usual sound of the paleontologists' laboratory.

Marable threw back his blond head. He glanced again toward the dark haired, blue eyed young woman, but when he caught her eye, he looked away and spoke to her father, Professor Young.

"I think that big one will turn out to be the largest single piece of amber ever mined," he said. "There were many difficulties in getting it out, for the workmen seemed afraid of it, did not want to handle it for some silly reason or other."

Professor Young, curator, was an expert in his line, but young Marable had charge of these particular fossil blocks, the amber being pure because it was mixed with lignite. The particular block which held the interest of the three was a huge yellow brown ma.s.s of irregular shape.

Vaguely, through the outer sh.e.l.l of impure amber, could be seen the heart of ink. The chunk weighed many tons, and its crate had just been removed by some workmen and was being taken away, piece by piece.

The three gazed at the immense ma.s.s, which filled the greater part of one end of the laboratory and towered almost to the skylights. It was a small mountain, compared to the size of the room, and in this case the mountain had come to man.

"Miss Betty, I think we had better begin by drawing a rough sketch of the block," said Marable.

Betty Young, daughter of the curator, nodded. She was working as a.s.sistant and secretary to Marable.

"Well--what do you think of them?"

The voice behind them caused them to turn, and they looked into the face of Andrew Leffler, the millionaire paleontologist, whose wealth and interest in the museum had made it possible for the inst.i.tution to acquire the amber.

Leffler, a keen, quick moving little man, whose chin was decorated with a white Van d.y.k.e beard, was very proud of the new acquisition.

"Everybody is talking about the big one," he continued, putting his hand on Marable's shoulder. "Orling is coming to see, and many others. As I told you, the workmen who handled it feared the big one. There were rumors about some unknown devil which lay hidden in the inklike substance, caught there like the proverbial fly in the amber. Well, let us hope there is something good in there, something that will make worth while all our effort."

Leffler wandered away, to speak to others who inspected the amber blocks.

"Superst.i.tion is curious, isn't it?" said Marable. "How can anyone think that a fossil creature, penned in such a cell for thousands and thousands of years, could do any harm?"

Professor Young shrugged. "It is just as you say. Superst.i.tion is not reasonable. These amber blocks were mined in the Manchurian lignite deposits by Chinese coolies under j.a.panese masters. They believe anything, the coolies. I remember working once with a crew of them that thought--"

The professor stopped suddenly, for his daughter had uttered a little cry of alarm. He felt her hand upon his arm, and turned toward her.

"What is it, dear?" he asked.

She was pointing toward the biggest amber block, and her eyes were wide open and showed she had seen something, or imagined that she had seen something, that frightened her.

Professor Young followed the direction of her finger. He saw that she was staring at the black heart of the amber block; but when he looked he could see nothing but the vague, irregular outline of the inky substance.
