They diffused the rays of eight giant searchlights into a vertical fan, and with it swept slowly through almost a semi-circle before anything was seen. Then there was revealed a cluster of cylindrical objects amid a mass of wreckage, which Crane recognized at once.

"The Kondal is gone, Dick. There is what is left of her, and most of her cargo of salt, in jute bags."

As he spoke, a series of green flashes played upon the bags, and Seaton yelled in relief.

"They got the ship all right, but Dunark and Sitar got away—they're still with their salt!"

The Skylark moved over to the wreck and Seaton, relinquishing the controls to Crane, donned a vacuum suit, entered the main air-lock and snapped on the motor which sealed off the lock, pumped the air into a pressure-tank, and opened the outside door. He threw a light line to the two figures and pushed himself lightly toward them. He then talked briefly to Dunark in the hand-language, and handed the end of the line to Sitar, who held it while the two men explored the fragments of the strange vessel, gathering up various things of interest as they came upon them.

Back in the control-room, Dunark and Sitar let their pressure decrease gradually to that of the terrestrial vessel and removed the face-plates from their helmets.

"Again, oh Karfedo of Earth, we thank you for our lives," Dunark began, gasping for breath, when Seaton leaped to the air-gauge with a quick apology.

"Never thought of the effect our atmospheric pressure would have on you two. We can stand yours all right, but you'd pretty nearly pass out on ours. There, that'll suit you better. Didn't you throw out your zone of force?"

"Yes, as soon as I saw that our screens were not going to hold." The Osnomians' labored breathing became normal as the air-pressure increased to a value only a little below that of the dense atmosphere of their native planet. "I then increased the power of the screens to the extreme limit and opened the zone for a moment to see how the screens would hold with the added power. That instant was enough. In that period a concentrated beam, such as I had no idea could ever be generated, went through the outer and inner screens as though they were not there, through the four-foot arenak of the hull, through the entire central installation, and through the hull on the other side. Sitar and I were wearing suits...."

"Say, Mart, that's one bet we overlooked. It's a good idea, too—those strangers wore them all the time as regular equipment, apparently. Next time we get into a jam, be sure we do it; they might come in handy. Excuse me, Dunark—go ahead."
