Chapter 9: A Subterranean World

The metal plate that had sealed him in this tomb fell open with a crash. Beyond it the passageway was alive with crowding red figures. Above their heads the nozzles of a score of flame-throwers spat jets of green fire. Rawson drew back in sudden uncontrollable horror as they came crowding into the room.

The familiar feel of the bailer’s cold metal had given him a momentary sense of oneness with his own world. Now this inrush of hideous, demoniac figures beneath the flare of green flames was like a fevered vision of the infernal regions come suddenly to actuality.

Rawson retreated to the shattered, rocky wall and prepared for one last fight, until he realized that the evil black eyes in their ghastly circles of white skin were fixed upon him more in curiosity than in active hatred.

They formed a semicircle about him--a wall of red bodies, whose pointed heads were craned forward, while an excited chatter in their broken, whistling speech filled the room with shrill clamor. Then one of them pointed above toward the open shaft that Rawson had drilled, the shaft up which the bailer had gone. And again their voices rose in weird discord, while their long arms waved, and red, lean-fingered hands pointed.

Only a moment of this, then one of them gave an order. Two of the red figures came toward Rawson where he was waiting. They were unarmed. They motioned that he was to go with them. And Dean, with a helpless shrug of his shoulders, allowed them, one on each side, to take him by the arms and hurry him through the open door. Two others went ahead, the green jets of flame from their weapons lighting the passage.

The system of communicating tunnels seemed at first only the vents and blow-holes from some previous volcanic activity. And yet, at times they gave place to more regular arrangement that plainly was artificial. The air in them was pure, though odorous with a pungent tang which Dean could not identify. Through some of the passages it blew gently with uncomfortable warmth.

The guard of wild red figures hurried him along through a vast world of caverns and winding passages which seemed one great mine. The richness of it was amazing. Dean Rawson was a man, a human being, facing death in some form which he could not yet know, and, so fast had his wild experiences crowded in upon him, he seemed numbed to all normal emotions; yet through it all the mind of the engineer was at work, and Dean’s eyes were flashing from side to side, trying to see and understand the ever-changing panorama of a subterranean world.

Mole-men, both red and yellow, were everywhere. But it was apparent at a glance that the yellow giants were a race of toilers--slaves, driven by the reds.

Their great bodies glowed orange-colored with the reflected heat of the blasts of flame used to melt the metals from their ores. Gold and silver, other metals that Rawson could not distinguish in the half light--the glow of the molten stuff came from every distant cave that the passages opened up.

The sheer marvel of it overwhelmed him. His own danger, even the death that waited for him, were forgotten.

A world within a world--and who knew how far it extended? Mole-men, by scores and hundreds, the denizens of a great subterranean world, of which his own world had been in ignorance. Here was civilization of a sort, and now the barriers that had separated this world from the world above had been broken down; the two were united. Suddenly there came to Rawson’s mind a flashing comprehension of a menace wild and terrible that had come with the breaking of those barriers.

They were passing through a wider hall when the whistling chatter of Dean’s escort ceased. They were looking to one side where a cloud of smoke had rolled from a slope beyond. One of the red figures staggered, choking, from the cloud. Two yellow mole-men followed closely after.
