To an outside observer, the appearance of the air-car and its subsequent movements would have been incomprehensible. There lay the hill, desolate, barren, apparently lifeless: and there, washing against its slopes, the lake; nothing more. Then suddenly a curve of gleaming steel thrust up through the muddy water, rose swiftly almost straight into the cloudless blue of the sky, and as suddenly disappeared, and remained gone from sight, as if the ether had opened and swallowed it.


sing his infra-red device, Carse brought the car in neatly through the ship-size port-lock of the dome, and sped it across to the central building, to land lightly beside one of the wings. Debarking, he ran down the wing's passage and in a few seconds was back in the asteroid's control room.

Friday was sitting in a chair close by the bound Eurasian; Ban Wilson, more restless, was pacing up and down. The Hawk nodded in response to their looks of welcome and issued curt orders.

"All ready. Ban, the air-car's just outside; go over and get those four men and the coolie and put them in it. Have your raygun ready, but don't use it if humanly possible. We're going down to the laboratory. I want speed. Please hurry."

"Right Carse!"

"Friday," the Hawk continued, "help me untie Dr. Ku."

They stooped to the chair and the impassive, silken figure sitting in it, and in a moment the bonds were ripped off; all save those on the wrists. Stretching himself, the Eurasian asked:

"You are taking the brains down now, Captain Carse?"
