His bones creaked. His skin rustled as he sat up and looked around. There was the old feeling that there was dust over everything when there was no dust. There was all that emptiness sweeping away into the endless silence and he thought again, as he always did, how comforting and cozy it was being a part of the Crew. But someone had to check the ship. It was only machinery after all, and machinery could wear out, sooner or later. And he wasn't at all sure, as he kept insisting, that they had encountered all the possible dangers. It might seem that in fifty years you could run into everything. But fifty years was no time at all out here where time had no real meaning any more. His body squeaked as he took a few tentative steps about the bunkroom. One did not actually forget how to walk. It was just awkward as the devil. And the blood, the entire autonomic system, tended to slow down. It seemed reluctant to step up general metabolism. Apathy. Sure it was a danger. This time, Kelly decided, I'll do something about it. He was the engineer and he had signed on the great odyssey to keep the ship going. But the Crew was part of the ship. Was not there an obligation even greater to keep the Crew going? The four others lived but almost imperceptibly in some very low state of slowed metabolism there in the bunkroom and Kelly looked at them. The faithful and the wonderful ones. The ones with whom he had shared so many dangers and awful silences that the five of them had been able to evolve the idea of the protoplasm in the tank and merge their consciousness in it. Kew, the Venusian, in her bowl of self-renewing nitrate. Lakrit from a Jovian satellite, a fluorine fellow of distinction inside a sphere of gaseous sulphur. A crystalline character with a sense of humor named Lljub, whose form gave off a paled glint as it nourished itself on silicates. And a highly intelligent but humble six-foot-long sponge labeled Urdaz stuck in a foundation of chemical sediment at the bottom of a tank of reprocessing salt water. Each with their own special kind of appendages and sensitivities, each able to move his special closed-system about through the ship by means of clever types of mobility. But basically, in outward form, they were too alien to have much in common. Only as intelligences, as life forces, could they share a common bed. And it had evolved to that in fifty years. A bed of protoplasm in a shock-absorbent tank. Kelly looked at them warmly and thought about how it had worked out. The strange thing was that it did have a lot of good things to recommend it. Or had had them. It had solved the problem of intimate communication and driven back the tides of loneliness. It had lessened the dangers of mental and physical illnesses in the material bodies and assured a prolongation of the life of each body, which was important in itself, for this trip had proven to be a lot longer than even the most pessimistic had anticipated.
