Diane obeyed. It was the merest flip of a switch. Then her eyes went back to the spherical-sweep scanners which reported the bearing and distance of every solid object within their range. She set up two instruments which would measure the angle, bearing, and distance of the two planets now on this side of the sun—the gas-giant and the oxygen-world to sunward. Their orbital speeds and distances were known. The position, course, and speed of the Niccola could be computed from any two observations on them.

Diane had returned to the utterly necessary routine of the radar room which was the nerve-center of the ship, gathering all information needed for navigation in space. The fact that there had been a collision, that the Niccola’s engines were melted to unlovely scrap, that the Plumie ship was now welded irremovably to a side-keel, and that a Plumie was signaling to humans while both ships went spinning through space toward an unknown destination—these things did not affect the obligations of the radar room.

Baird got other images of the Plumie ship into sharp focus. So near, the scanners required adjustment for precision.

“Take a look at this!” he said wryly.

She looked. The view was of the Plumie as welded fast to the Niccola. The welding was itself an extraordinary result of the Plumie’s battle-tactics. Tractor and pressor beams were known to men, of course, but human beings used them only under very special conditions. Their operation involved the building-up of terrific static charges. Unless a tractor-beam generator could be grounded to the object it was to pull, it tended to emit lightning-bolts at unpredictable intervals and in entirely random directions. So men didn’t use them. Obviously, the Plumies did.

They’d handled the Niccola’s rockets with beams which charged the golden ship to billions of volts. And when the silicon-bronze Plumie ship touched the cobalt-steel Niccola—why—that charge had to be shared. It must have been the most spectacular of all artificial electric flames. Part of the Niccola’s hull was vaporized, and undoubtedly part of the Plumie. But the unvaporized surfaces were molten and in contact—and they stuck.

For a good twenty feet the two ships were united by the most perfect of vacuum-welds. The wholly dissimilar hulls formed a space-catamaran, with a sort of valley between their bulks. Spinning deliberately, as the united ships did, sometimes the sun shone brightly into that valley, and sometimes it was filled with the blackness of the pit.

While Diane looked, a round door revolved in the side of the Plumie ship. As Diane caught her breath, Baird reported crisply. At his first words Taine burst into raging commands for men to follow him through the Niccola’s air lock and fight a boarding party of Plumies in empty space. The skipper very savagely ordered him to be quiet.

“Only one figure has come out,” reported Baird. The skipper watched on a vision plate, but Baird reported so all the Niccola’s company would know. “It’s small—less than five feet ... I’ll see better in a moment.” Sunlight smote down into the valley between the ships. “It’s wearing a pressure suit. It seems to be the same material as the ship. It walks on two legs, as we do ... It has two arms, or something very similar ... The helmet of the suit is very high ... It looks like the armor knights used to fight in ... It’s making its way to our air lock ... It does not use magnetic-soled shoes. It’s holding onto lines threaded along the other ship’s hull ...”

The skipper said curtly:
