Dick remained in his chair long after the others had gone to their cabins. His mind dwelled on the complete happiness and satisfaction that lighted Morquil's face, when informed of their decision. In that moment he was repaid for a lifetime in a strange world, amongst alien people. His return to Jupiter would be triumphal, with the earth people as his friends; come to save his race from extinction! Barrow's mind wandered on, to the gigantic task that faced them. His would be the greatest responsibility, as head of all the domes. The other men would have a single city to care for. The thought of McCarthy as his assistant was comforting; he would be a great help. The strange race of beings were putting every trust in the earthmen--putting themselves at the mercy of the seven strangers--and Dick knew the men would _earn_ that faith! He jumped when a hand touched his shoulder. "Dick, won't you take your wife to her room--she feels sleepy!" CHAPTER V _Voyaging to Another World_ During each waking period, Barrow spent many hours in the room with the miniature domes. They were beautiful models, which could be opened or moved as desired, by small levers on the foundation. Wires as fine as hairs were strung from one spot to another, while metal the size of thread represented heavy cables. Slowly, an understanding of the strange civilization formed in Dick's mind, and he drew sectional maps of the location of all mechanical equipment. Other maps pictured the streets, so that it would be easy to reach any desired destination. When this was done, Morquil sent one of his men down to make as many copies as desired. Each engineer was to have a complete set. The earthmen had learned to keep track of the time according to the system on the ship. Each "lix" included the time spent in sleep as well as one waking period. It was twenty-seven hours in length, but they all thought of it as a day. Each lix was divided into thirty-six "migs." Each mig being just forty-five minutes in length. They were able to keep track of each mig, by their watches, although the time pieces were useless for any other purpose. One lix, Dick returned the friendly smile of a member of the crew, and to his amazement the man spoke. "Chickiboo." For a moment Barrow was stumped, then realized that it must be a greeting. When he was greeted the same way, by a second and then a third man, he tried to imitate the words. The man from Jupiter was so pleased that he almost danced, then spoke again. "Gootmording." Dick's jaw almost dropped open; the man was trying to speak _English_! Suddenly Barrow laughed. Morquil had been instructing his crew in the strange language, as well as telling them to greet the earthmen in their own tongue. He must speak about holding classes to learn the language. They would have to understand it, and the sooner they started the easier it would be.
