THREE:The bodies of Bob Willis and Jim Humphreys were wrapped in their blankets, and mournfully consigned to the earth. A cedar bush was stuck in the head of each grave, and Si, finding a piece of smooth board and a chunk of soft charcoal from a fire, sat down on the bank, and begun laboriously composing the following inscription:The Commons Room of the Third Building of City One was a large affair, whose three bare metal walls enclosed more space than any other single living-quarters room in the Building; but the presence of the fourth wall made it seem tiny. That wall was nearly all window, a non-shatterable clear plastic immensely superior to that laboratory material, glass. It displayed a single unbroken sweep of forty feet, and it looked down on the forests of Fruyling's World from a height of sixteen stories. Men new to the Third Building usually sat with their backs to that enormous window, and even the eldest inhabitants usually placed their chairs somehow out of line with it, and looked instead at the walls, at their companions, or at their own hands.
