The Great Dome On Mercury

Two white spots showed on either side of Darl’s nostrils. His mouth was a thin white slit, his eyes gray marbles. Standing against the wall beside him was a space suit, mirror-surfaced and double-walled against the planet’s heat. In a few moments he was encased within it, had snatched a pocket ray-gun from the long rack, and was through the door to the auxiliary air-lock. The air soughed out in response to his swift thrust at a lever, a second door opened, and he was on the outside, reeling from the blast of that inferno of light and heat.
For a moment the Earthman was dazzled, despite the smoked quartz eye-pieces in his helmet. Then, as his eyes grew used to the glare, he saw, far below, the erect figure of the stranger. The man was standing still, waiting. His immobility, the calm confidence with which he stood there, was insolently challenging. Darl’s rage flared higher at the sight.

Scorning the ladder that curved along the Dome to the ground, he threw himself at the polished round side of the great hemisphere. With increasing speed he slid downward, the gleaming surface breaking only slightly the velocity of his fall. On Earth this would have been suicidal. Even here, where the pull of gravity was so much less, the feat was insanely reckless. But the heat-softened ground, the strength of his metal suit, brought Darl safely through.
He whirled to meet the expected onslaught of the interloper. The green tube was aimed straight at him! The Earthman started to bring his own weapon up when something exploded in his brain. There was a moment of blackness; then he was again clear-minded. But he could not move–not so much as the tiny twist of his wrist that would have brought his own weapon into play.
Frozen by this strange paralysis, Darl Thomas saw the giant figure approach. The apparition bent and slung him to its shoulder. Glowing walls rose about him, dimmed. The Terrestrian knew that he was being carried down into one of the myriad openings that honeycombed the terrain. The luminescence died; there was no longer light enough to penetrate to his helmet’s darkened goggles.
Frantic questions surged through the captured Earthman’s mind. Who was his captor? From where, and how, had he come to Mercury? Jim, Angus McDermott, and himself were the only Terrestrians on the planet; of that he was certain. Only one or two of the reptile-skinned Venusian laborers had sufficient intelligence to manipulate a space suit, and they were unquestionably loyal.
This individual was a giant who towered far above Darl’s own six feet. The Mercurian natives–he had seen them when ITA’s expedition had cleaned out the burrows beneath the Dome and sealed them up–were midgets, the tallest not more than two feet in height. Whatever he was, why was the stranger trying to destroy the Dome? Apparently Thomas himself was not to be killed offhand: the jolting journey was continuing interminably. With enforced patience the Earthman resigned himself to wait for the next scene in this strange drama.

In the headquarters tent Jim’s usual grin was absent as he moved restlessly among the switches and levers that concentrated control of all the Dome’s complex machinery. “Darl’s been gone a devilish long time,” he muttered to himself. “Here it’s almost time for shifts to change and he’s not back yet.”
A bell clanged, somewhere up in the mass of cables that rose from the control board. For the next ten minutes Holcomb had no time for worry as he rapidly manipulated the innumerable wheels and handles in accord with the vari-colored lights that flickered on a huge ground-glass map of the sub-Mercurian passages. On the plain outside there was a vast rustling, a many-voiced twittering and squeaking that was not quite bird-like in tone. Through the opened tent-flap one could see the stream of Venusian workers, their work-period ended, pouring out of the shaft-head and filing between the ordered ranks of others whose labors were about to begin.
