ten o'clock
It seemed as though ten o'clock would never come . Frank had a small pocket electric light with him , run by a dry battery , and , by pressing a button , a faint glow could be had . By means of this the boys frequently glanced at their watches . `` I 'm not going to look again until I think it 's ten o'clock , '' declared Frank . But he could not resist , and , after waiting what seemed like an hour he glanced at the time-piece again . It was half-past nine . `` Half an hour more , '' he announced .
