His uncle wasn't much gentler with him. "Eric the _Eye_!" the Trap-Smasher growled. "Eric the Eyebrow, Eric the Closed Eyelash, you'll be known as, if you don't wake up! Now stay abreast of me and try to _act_ like Eric the Eye. These are dangerous burrows and my vision isn't as sharp as yours. Besides, I have to fill you in on a couple of things." He turned. "Spread out a little farther back there," he called out to the men behind him. "Spread out! You should be a full spear-cast from the backside of the man in front of you. Let me see a real strung-out column with plenty of distance between each warrior." * * * * * To Eric, he muttered, once the maneuver had been completed: "Good. Gives us a chance to talk without everyone in the band hearing us. You can trust my bunch, but still, why take chances?" Eric nodded, with no idea what he was talking about. His uncle had become slightly odd recently. Well, he was still the best band captain in all Mankind. They marched along together, the light from the strange glowing substance on Eric's torch and his uncle's forehead spreading a yellowish illumination some hundred feet ahead of them. On either side, underfoot, overhead, were the curved, featureless walls of the burrow. From the center of the corridor, where they marched, the walls looked soft and spongy, but Eric knew what tremendous labor was involved in digging a niche or recess in them. It took several strong men at least two sleep periods to make a niche large enough to hold a handful of Mankind's store of artifacts. Where had the burrows come from? Some said they had been dug by the ancestors when they had first begun to hit back at the Monsters. Others claimed the burrows had always been there, waiting for Mankind to find them and be comfortable in them. In all directions the burrows stretched. On and on they went, interminably curving and branching and forking, dark and silent, until human beings stamped into them with glow lamp and glow torch. These particular corridors, Eric knew, led to Monster territory. He had been along them many times as a humble spear carrier when his uncle's band had been dispatched to bring back the necessities of life for Mankind. Other corridors went off to more exotic and even more dangerous places. But were there any places which had no burrows? What a thought! Even the Monsters lived in burrows, big as they were reputed to be. But there was a legend that Mankind had once lived outside burrows, outside the branching corridors. Then what had they lived in? Just trying to work it out made you dizzy. They came to a place where the burrow became two burrows, each curving away from the other in opposite directions. "Which one?" his uncle demanded. Eric unhesitatingly pointed the right.
