"What do you suppose was the matter with the thing?" Jack asked a few minutes later as he sat in the wireless room with the receivers on his head.
"There's a lot of things could account for it," Bob replied from the couch, at one side of the little room, where he was stretched reading a book. "Not enough power for one thing, and then, you know, father's not much used to working it and he might have got something wrong."
A half hour later, having failed to pick up the call letters of the Valkyrie, Jack was about to give it up when suddenly, through the night, clear and sharp came a signal which brought him to his feet with a quick cry.
"What is it?" Bob asked.
"S-O-S."
"Where from?"
"Doesn't say yet."
"Does he sound near?"
"Can't be far off. There, he's starting to give his position."
