There were no houses or tents or any structures with roofs. Each family group apparently fenced off their section of ground with a barrier of low, pointed sticks, their points diagonally outward. Within this barrier, the family squatted with their few possessions. There was no such thing as privacy among this primitive group. The females of the tribe apparently stayed within their family plots, with the young, the extra spears and hunting sticks, the leftover supplies of food, and a pile in the center of each circle of what must have been some sort of blankets, apparently woven crudely from vegetable fibers. Robin assumed that during the cold periods, these were used.

The males of the tribe were gathered before a central circle, watching their visitors approach. Korree went to them, stopped, and spoke at length. Robin could not understand him, but he knew what he must be saying. His Glassie friend was obviously first boasting of his friendship with the magical stranger, then warning them of terrible consequences if they failed to obey and honor the stranger, doubtless inserting a demand for his own full pardon of whatever tribal offense had brought about his own banishment, and demanding the aid of the tribal leaders in assisting them on their way.

When he had finished, Robin walked straight up to the Glassie with the chest marking, reached out and extracted from the tip of his quivering light-organ stalk a copper cent which Robin had first palmed in his hand. To the astonished native, he presented this token—one of the coins Robin had had in his pocket on his unexpected trip from New Mexico.

The Glassie took it, stared at it. The face on the coppery-yellow coin seemed to hypnotize him. No one had ever seen such a thing—a bit of bright rock with a face on it! But this additional evidence of Robin's magic clinched the argument.

Robin and Korree stayed in that cavern for about three days. In that time Korree managed to obtain fairly specific directions from one old-timer as to the cavern they sought. He had also evidently repaired his tribal fences, for Robin could not fail to notice that Korree was always accompanied by a group of anxious and placating Glassies. He imagined that when Korree returned to stay, it would be as a chieftain.

The nature of the tribe's culture remained much of a mystery. They were very primitive, yet they seemed to have a complicated series of taboos and ceremonies. There was clearly a very definite code of marriage and family relations, though its limitations were puzzling.

Robin discovered something about them, however. One of the circular enclosures was apparently a tribal storehouse, or temple, or arsenal, or magic circle—exactly what he could not tell—save that no family lived within and there were little piles of oddities carefully placed inside its magic circle. The penny Robin had "pulled from the chief's head" reposed therein on a raised mound. The burnt match stick lay beside it. The rest of the contents seemed to be curiously shaped stones, odd bits of animal skin, a skeleton of something big and round which might perhaps have been that of a Moonbowler slain by the hero of the tribe. Several diamond spearheads were there, including some that had fractured in use. And something that glistened like metal.

Robin saw this latter, and, stepping boldly inside the magic circle, picked this object up and examined it. It was a knife blade!

It was nothing of Terrestrial manufacture. It was about nine inches long and a couple of inches wide at the hilt, tapering down to a point. It was edged on one side, and bore the marks of having been hammered down and shaped by a hand mallet rather than ever having felt the heat of a forge. Engraved in its rather soft white metal were a series of odd hooks and lines that looked like writing of a sort. The hilt end was jagged as if the blade had been snapped off in careless usage.

Robin called to Korree and asked him about the object. Korree consulted with the chief and returned. "Sharp thing, it come from down-there people," he said, pointing to the regions below. "Glassie of those die in break of tunnel. We find, take this."
