"If that is their plan, they have not yet done it." Sssuri rolled over on his back and stretched. He had lost that tenseness of a hound in leash which had marked him the night before. "This was one of their secret places, holding much of their knowledge. They may return here on quest for that learning." All at once Dalgard was conscious of a sense of urgency. Suppose that what Sssuri suggested was the truth, that Those Others were attempting to recover the skills which had brought on the devastating war that had turned this whole eastern continent into a wilderness? Equipped with even the crumbs of such discoveries, they would be enemies against which the Terran colonists could not hope to stand. The few weapons their outlaw ancestors had brought with them on their desperate flight to the stars were long since useless, and they had had no way of duplicating them. Since childhood Dalgard had seen no arms except the bows and the sword-knives carried by all venturing away from Homeport. And what use would a bow or a foot or two of sharpened metal be against things which could kill from a distance or turn rock itself into a flowing, molten river? He was impatient to move on, to reach this city of forgotten knowledge which Sssuri was sure lay before them. Perhaps the colonists could draw upon what was stored there as well as Those Others could. Then he remembered--not only remembered but was corrected by Sssuri. "Think not of taking _their_ weapons into your hands." Sssuri did not look up as he gave that warning. "Long ago your fathers' fathers knew that the knowledge of Those Others was not for their taking." A dimly remembered story, a warning impressed upon him during his first guided trips into the ruins near Homeport flashed into Dalgard's mind. Yes, he knew that some things had been forbidden to his kind. For one, it was best not to examine too closely the bands of color patterns which served Those Others as a means of written record. Tapes of the aliens' records had been found and stored at Homeport. But not one of the colonists had ventured to try to break the color code and learn what lay locked in those bands. Once long ago such an experiment had led to the brink of disaster, and such delvings were now considered too dangerous to be allowed. But there was no harm in visiting this city, and certainly he must make some report to the Council about what might be taking place here, especially if Those Others were in residence or visited the site.
