He remembered his purpose and went with a long low-gravity stride to check the mineralogical unit. It was busily breaking down materials fetched in by the robosamplers, stones never found on Earth--because Earth is not the Mercury-sized satellite of an outer planet, nor has it seen some mysterious catastrophe in an unknown time back near the beginning of things. Recording meters wavered needles across their dials, data tapes clicked out, he would soon have the basic information. Then he would try to figure out how the mineral could have been formed, and give his hypothesis to the computer for mathematical analysis of possibility, and start on some other sample. For a while Gilchrist stood watching the machine. A cigaret smoldered forgotten between his fingers. He was a short, pudgy young man, with unkempt hair above homely features. Pale-blue eyes blinked nearsightedly behind contact lenses, his myopia was not enough to justify surgery. Tunic and slacks were rumpled beneath the gray smock. _Behold the bold pioneer!_ he thought. His self-deprecating sarcasm was mildly nonsane, he knew, but he couldn't stop--it was like biting an aching tooth. Only a dentist could fix the tooth in an hour, while a scarred soul took years to heal. It was like his eyes, the trouble wasn't bad enough to require long expensive repair, so he limped through life. Rafael Alemán came in, small and dark and cheerful. "'Allo," he said. "How goes it?" He was one of the Hill's organic chemists, as Gilchrist was the chief physical chemist, but his researches into low-temperature properties were turning out so disappointingly that he had plenty of time to annoy others. Nevertheless, Gilchrist liked him, as he liked most people. "So-so. It takes time." "Time we have enough of, _mi amigo_," said Alemán. "Two years we 'ave been here, and three years more it will be before the ship comes to relieve us." He grimaced. "Ah, when I am back to Durango Unit, how fast my savings will disappear!" "You didn't have to join the Corps, and you didn't have to volunteer for Triton Station," Gilchrist pointed out. The little man shrugged, spreading slender hands. "Confidential, I will tell you. I had heard such colorful tales of outpost life. But the only result is that I am now a married man--not that I have anything but praise for my dear Mei-Hua, but it is not the abandonment one had hoped for." Gilchrist chuckled. Outer-planet stations did have a slightly lurid reputation, and no doubt it had been justified several years ago. After all--The voyage was so long and costly that it could not be made often. You established a self-sufficient colony of scientists and left it there to carry on its researches for years at a time. But self-sufficiency includes psychic elements, recreation, alcohol, entertainment, the opposite sex. A returning party always took several children home.
