is master nodded, and said in a low, thoughtful voice: "In spite of what some men have said, I never like to kill; but for these robots, more machines than men, with nothing human to live for, it's release rather than death.

"Well," he began again, more briskly, "we're inside, and whoever else is here apparently doesn't know it yet. I expected more of a commotion. I wonder how many coolies Ku Sui had, altogether? Fourteen or fifteen were killed when we broke through the dome, before, and now these three. There surely can't be many left. Of course, there are the four white men, his surgical assistants."

Ban Wilson spoke after what was for him a long silence. He had watched the Hawk's gunplay with an awe-stricken face; its speed never failed to amaze him. He observed:

"These buildings certainly look lifeless. Well, what now, Carse?"

"A search." He planned it out in his head, then gave quick orders. "Ban," he directed, "you go through all the out-buildings, your gun ready. The five main ones are a workshop, a power-house, storehouse, a ship hangar and a barracks for coolies. Whoever you find, take prisoner. Keep in touch with me by radio."

"Friday," he continued, "I'm leaving you here. First get these bodies in that guard-house they came out of. Then keep sharp watch. I don't think Ku Sui will return within fifteen minutes, but we must take no chance. At the first sign of him, warn me."

"Yes, suh. But what are you goin' to do?"

"Take over the central building," said the Hawk. "And then, when the whole place has been reconnoitered, fulfil my promise to the brains."
