The things showed no fear, no intelligence. But one by one they sensed the nearness of the copper helmets we wore, and detached themselves from the ship. They moved like red tongues of flame upon the fat sides of the _Ertak_; crawling, uneasy flames, releasing themselves swiftly, one after the other. * * * * * Our sprays met them in mid-air, and they dissolved like mist, one after the other.... I directed my death-dealing spray with a grim delight, and as each glowing heart crackled and exploded, I chuckled to myself. The sweat was running down my face; I was shaking with excitement One side of the ship was already cleared of the things; they were slipping over the top now, one or two at a time, and as rapidly as they came, we wiped them out. At last there came a period in which there were none of the things in sight; none coming over the top of the sorely tried ship. "Stay here and watch, Hendricks," I ordered. "I'll look on the other side. I believe we've got them all!" I hurried, as best I could, around to the other side of the _Ertak_. Her hull was pitted and corroded, but there was no other evidence of the crescent-shaped things which had so nearly brought about the ship's untimely, ghastly end. "Hendricks!" I emanated happily. "'Nothing Less Than Complete Success!' And that's ours right now! They're gone--all of them!" I slipped the contrivances from my shoulders and ran back to the other side of the ship. Hendricks was executing some weird sort of dance, patting the containers, swinging them wildly about his body, with an understandable fondness. "Come inside, you idiot," I suggested, "and tell us how you did it. And see how it feels to be a hero!" * * * * * "It was just luck," Hendricks tried to make us believe, a few minutes later, when Kincaide, Correy, and myself were through slapping his back and shaking his hands. "When you, sir, splashed into the water, I had just torn off my mask. I saw some of the water fall on one of the things clustered upon your helmet, and I distinctly heard it hiss, as it fell. And where it fell, it made a ragged hole, which very slowly closed up, leaving a dim spot in the tentacle where the hole had been. As I figure it, the water--to put it crudely--short-circuited the electrical energy of the things. That, too, is just a guess, but I think it's a good one. "Of course, it was a long chance, but it seemed like our only one. There was nothing more or less than acidulated water in the containers; and the air flasks, of course, were merely to supply the pressure to throw the water out in a powerful spray. It happened to work, and there isn't anybody any happier about it than I am. I'm young, and there're lots of things I want to do before I bleach my bones on a little deserted world like this, that isn't important enough to even have a name!"
