'Look,' cried Reggie, 'they're signalling something from the Heroic.'
A string of flags had suddenly floated out from the Heroic's masthead.
'Wait, and I'll fetch a spy-glass,' said Allan, running towards the house.
'Something about telling something to Father,' he said, after studying the signals for awhile; 'I can't make out the rest.'
They looked at each other with frightened eyes.
'Here, Reggie,' said Allan, handing him the glass, 'you try.'
Reggie looked, then shook his head.
'Can't make anything of it,' he said.
'Perhaps they want us to come on board again,' said Harry. 'You might give me the glass for a minute, Reggie.'
'They can't have been exploring already?' suggested Marjorie, in a voice designed only for Allan's and Reggie's ears.
