Again and again he crushed the life out of a Rogan with his one-two swing of the deadly bar. They were thinning down, now. They were wavering in their charges against the comparatively insignificant being from another planet who was defending himself so fiercely. * * * * * Finally one of their number turned and ran toward an exit, waving his four arms and adding his high-pitched alarms to the incessant ringing of the gongs and shrieks of the warning siren up under the roof. The rest rushed the Earthman in a body. Steadily, almost joyfully, Brand fought on. He had expected to be annihilated by one of the Rogan shock-tubes long before now; but as yet there was no sign of any. Either these Rogan workmen were not privileged to carry the terrible things, or they were too occupied to think of going and getting them; anyhow, Brand was left free to wield his bar and continue crushing out the lives of the two-legged vermin that attacked him. With almost a shock of surprise, he saw finally that he had battered their number down to three. At that he took the offensive himself. He rammed the bluntly pointed end of the bar almost through one writhing torso, broke the back of a second with a whistling blow, and tripped and exterminated the third almost in as many seconds. The creatures, without their death-tubes, were as helpless as crippled rats! Panting, he turned again toward the loosened glass bell, and battered at it with the precious bar. Gradually the bolts that held it to the stone slab were wrenched out, till only one supported it. But at this point, from half a dozen set-back doorways, streams of infuriated Rogans began pouring into the building and toward him. The one that had fled had come back with help. CHAPTER VIII _Tremendous Odds_ Like living spokes of a half-wheel, with the Earthman as the hub, the Rogans converged toward Brand, a howling roar outside indicating that there were hundreds more waiting to jam into the dome as soon as they were able. There were still no shock-tubes in evidence: evidently the worker who had gone for help had gathered the first Rogan citizens he had encountered on the streets. But the very numbers of the mob spelled defeat for Brand. However, there was still the great lever behind him to yank away from its switch-socket. The glass bell was almost off now. With a last mad blow, he knocked loose the remaining bolt that held it. The bell clattered to the floor. A concerted shriek came from the crowding Rogans as they saw the Earthman's hand close on the lever. Whatever effect the throwing of that master-switch could have, there was no doubt that they were extremely anxious to prevent it! And now, in the rear of the crowding columns, appeared Rogans taller than the others, with an authoritative air, who waved before them, eager to unleash their power, batteries of the death-tubes.
