about ten o'clock
`` Bless my eyelids but I 'm tired out . '' As there was no necessity for standing watch , when the airship was so high up as to be almost invisible , they all turned in , and were soon sleeping soundly , though Tom had hard work at first to compose himself , for he was excited at the prospect of capturing the scoundrels , recovering the money for the bank , and clearing his good name , as well as those of his friends . In the morning careful calculations were made to enable the travelers to tell when they had reached a point directly over the small city of Shagmon , and , with the skill of the veteran balloonist to aid them , this was accomplished . The airship was headed in the proper direction , and , about ten o'clock , having made out by using telescopes , that there was plenty of uninhabited land about the city , the craft was sent aloft again , out of a large crowd that had caught sight of it . For it was the intention of the travelers not to land until after dark , as they wanted to keep their arrival quiet . There were two reasons for this . One was that the whole country was eager to arrest them , to claim the reward offered by the bank , and they did not want this to happen .
