"I'll just take it along anyway," I snapped. After leaving the dome through one of the airlocks, I headed out onto the surface of Mars, weighted down with my leaded boots, standard equipment for cutting down some of the effect of the one-sixth gravity of the planet. Over to the westward, possibly three miles away, seemed to be a barren, rocky area. I knew that Mike Holiday wouldn't have deliberately lied to me, that was where zloors were to be found. I made my way in that direction. "About the size of a rabbit," I muttered. "And half the hunters on earth can't bring one back." I made the rocky area and found myself a suitable prominence from which to look around. In less than fifteen minutes, I'd spotted one of the things. They were about the size of a rabbit all right, and what was more they looked considerably like one of the earth type rodents—long ears, nub of a tail. I watched it for some time through the small glass I'd borrowed from Mike. It was evidently eating the bark, and possibly the wood as well, of a stunted, rugged looking Martian tree which seemed to be growing out of almost solid rock. The boys had said that there were a lot of zloors around so I didn't have to worry about conversion. I took up the rifle, aimed carefully through the scope and squeezed the trigger. I was interested, eventually, in getting a live zloor, but it wouldn't hurt to have a closer look at one of the things to help me in planning my campaign. The gun snapped and I could see the tiny bullet spank into the little animal's side. I'd got him! But something didn't look right. I took up the telescope again and peered through it. The zloor was still eating. That stopped me. I could have sworn that I'd hit it, right amidships. I aimed even more carefully this time, for its head, and squeezed gently. That shot, too, hit dead center. But the zloor didn't bother to stop its feeding. I sat there a long time staring at it. Finally I snorted inwardly. Obviously, this was what had been stopping the others—this animal had some very effective natural body armor. Well—there is more than one way of skinning a zloor, as well as a cat. I picked up the rifle and headed down
