A Planet liner, east bound, heaves up in a superb spiral and takes the air of us humming. Her underbody colloid is open and her transporter-slings hang down like tentacles. We shut off our beam as she adjusts herself—steering to a hair—over the tramp's conning-tower. The mate comes up, his arm strapped to his side, and stumbles into the cradle. A man with a ghastly scarlet head follows, shouting that he must go back and build up his Ray. The mate assures him that he will find a nice new Ray all ready in the liner's engine-room. The bandaged head goes up wagging excitedly. A youth and a woman follow. The liner cheers hollowly above us, and we see the [passengers'] faces at the saloon colloid.

"That's a good girl. What's the fool waiting for now?" says Captain Purnall.

The skipper comes up, still appealing to us to stand by and see him fetch St. John's. He dives below and returns—at which we little human beings in the void cheer louder than ever—with the ship's kitten. Up fly the liner's hissing slings; her underbody crashes home and she hurtles away again. The dial shows less than 3,000 feet.

The Mark Boat signals we must attend to the derelict, now whistling her death song, as she falls beneath us in long sick zigzags.

"Keep our beam on her and send out a General Warning," says Captain Purnall, following her down.

There is no need. Not a liner in air but knows the meaning of that vertical beam and gives us and our quarry a wide berth.

"But she'll drown in the water, won't she?" I ask.

"Not always," is his answer. "I've known a derelict up-end and sift her engines out of herself and flicker round the Lower Lanes for three weeks on her forward tanks only. We'll run no risks. Pith her, George, and look sharp. There's weather ahead."

Captain Hodgson opens the underbody colloid, swings the heavy pithing-iron out of its rack which in liners is generally cased as a settee, and at two hundred feet releases the catch. We hear the whir of the crescent-shaped arms opening as they descend. The derelict's forehead is punched in, starred across, and rent diagonally. She falls stern first, our beam upon her; slides like a lost soul down that pitiless ladder of light, and the Atlantic takes her.
