Astounding Stories of Super-Science, June, 1930

Maget swallowed. "I've seen 'em two feet long," he said. "But never like that."

Durkin, however, when he realized that the loathsome creature could not see them and was creeping blindly towards them with its ugly, fat body creasing and elongating, picked up rocks and began to destroy the monstrous worm. He cursed as he worked.

Dull red blood spattered them, and a fetid odor from the gashes caused them to retch, but they finally cut the thing in two, and then they moved away from there.

The dull rumblings beneath them frightened Maget, and Durkin too, though the latter tried to brazen it out.

"Come on, it's gettin' dark. We can take a look in their mine now."

Maget, whimpering, followed. The booming sounds were increasing.

But Durkin slipped down the hillside, and Maget followed into the valley. They crept past the stone shack, which they noticed was padlocked heavily.

Durkin stopped suddenly, and cursed. "I've cut my foot," he said. "These damn shoes are gone, all right, from that march. But come on, never mind."

They crept to the mouth of the cavern and peered in. "Ugh," said Maget.

He drew back with a shudder. The floor of the mine was covered with a grey slush, in which were seething white masses of slugs weaving in the slime. A powerful, rotten odor breathed in their faces, as though they stood in the mouth of a great giant.

"Ah!" yelled Durkin, throwing his arms across his face.

The greenish, ghostly light which emanated from the slime was weaker than moonlight, just enough to see by; a vast shadow hovered above their heads, as though a gigantic bat flew there. The sweep and beat of great wings drove them back, and they fled in terror from such awful corruption.

But the flying monster, with a wing spread of eight feet, dashed past them, and silhouetted against the rising moon like a goblin. Then came another, and finally a flock of the big birds.

Durkin and Maget ran away, passing the stone house which stood near the cavern's mouth. The booming sounds from the bowels of the earth filled their ears now, and it was not thunder; no, it issued from the depths of the mine.

"We – we got to get somethin' to eat," said Durkin, as they paused near one of the shacks, in which shone a light.

Sounds of voices came from the interior. They crept closer, and listened outside the window. Inside, they could see Espinosa, Gurlone senior, and the big youth with the golden beard, Gurlone junior.

"Yes, father," the young man was saying. "I believe we had better leave, at once. It's getting dangerous. I've reached the five million mark now, with the new process, and it is ready to work with or sell, just as we wish."

"Hear that?" whispered Durkin triumphantly. "Five million!"

"It's all ready, in the stone house," said young Gurlone.

"Why should we leave now?" said old Gurlone, his livid face working. "Now, when we are just at the point of success in our great experiments? So far, while we have struck many creatures of abnormal growth, still, we have overcome them."

"Well, father, there is something in the mine now which makes it too dangerous to work. That is, until they are put out of the way. You can hear them now."

The three inside the shack listened, and so did Durkin and Maget. The booming sounds swelled louder and the earth of the valley shook.

"I t'ink we better go," said Espinosa gruffly. "I agree with your son, Professor."

"No, no. We can conquer this, what ever it is."

"You see, father, while you were away, we broke through into a natural cavern, an underground river. It was then that the trouble started. You know the effect of the stuff on the insects and birds. It enlarged a cricket one hundred times. You saw that yourself. Six of the peons have disappeared – they didn't run away, either. They went down the shaft and never came back."

"Oh, they probably fell into the water and drowned," said old Gurlone impatiently. "Even if they did not, we can kill anything with these large bore rifles."

"We'd better pull out and let it alone for a while," said young Gurlone gravely. "The peons have been trying to bolt for several days. They'd be gone now if I hadn't penned them in and electrified the fence."

Maget put his hand on his friend's shoulder. "I'm starving," he whispered.

Durkin nodded, and they turned away, toward what they had marked as a supply shack. They heard a low murmur from the peons' pen, as they began to break off the hasps of the lock which held the door of the storehouse.

They got inside with little trouble, and began to feel about in the dark for food. They located biscuits and canned goods which they split open, and these they wolfed hungrily, listening carefully for sounds from outside.

"Here they come," said Maget, gripping Durkin's arm.

They looked out the window of the supply shack, and saw old Gurlone issue from the building outside which the two tramps had been listening. In one hand, the old Professor, brave as a lion, carried an old fashioned double-barreled elephant gun, and the rays from a powerful electric torch shone across the barrel.

At least, they thought the bizarre figure was old Gurlone, from the size. For the man was clad in a black, shiny suit, and over his head was a flapping hood of the same material in which were large eyeholes of green glass. Behind this strange form came a larger one, armed also with a big bore rifle and with another powerful flashlight.

The blind Portuguese was armed, too, but he was not clad in the black suit. He took his stand beside the mouth of the cavern, and waited while the two Gurlones entered the mine.

"My foot hurts," said Durkin suddenly, breaking the silence.

"I'm going out and see what happens," said Maget.

Durkin limped after Maget, who now took the lead. They crept close as possible to the mine opening, and saw the big Portuguese standing there in silence, listening carefully. Any sounds the two might have made were drowned in the great bellowing from within the cavern.

These noises, so like the croak of bullfrogs but magnified a thousand times, were terrifying to the heart.

The sweep of wings sounded on the night air, and Espinosa drew back and squatted close to the ground, as immense green creatures, flying on dusty wings, issued from the mine.

"God, those are moths," breathed Maget.

Yes, unmistakably, they were moths, as large as condors. The green ones, but for their size, were lunar moths, familiar enough to the two tramps. More bats came, disturbed by the entrance of the two Gurlones.

Durkin broke, then. "I'm – I'm – I guess you're right, Maget," he whispered, in a terrified voice. "We should have never come. If my foot wasn't hurt, I'd start for the river now. Curse it, what a place!"

The booming, vast croaks filled the whole valley, reverberating through the hills. Wails sounded from the peon camp.

The big Portuguese was shouting to the Gurlones. "Come out, come out!"

Maget gripped his own rifle, and stood up, bravely. His fear, though it was great, seemed to have brought out the better side of the man, while Durkin, so brave at first, had cracked under the strain.

"Look out, they'll see you," whimpered Durkin.

Maget strode forward. A blast of fetid, stinking air struck his face, and he choked. The noises were now ear-splitting, but above the bellows came the sounds of the big rifles, the echoes booming through the recesses of the cavern.

Then the two Gurlones, running madly, burst from the mine entrance.

"Run," they screamed. "Run for your life, Espinosa!"

"I'll help you," cried Maget, and Durkin could detain him no longer.
