“Maybe the shot just carried away some of the light work like railings and so on around the deck. I don’t think the shot struck the hull, or we’d have heard more racket,” went on Ned.
“Let’s keep below the surface for a while. Maybe we can get away from those fellows far enough to be out of their sight while we change air. They’re not the least bit sociable!”
“Full speed ahead, Harry!” cried Frank. “Let’s hurry on!”
“Better take it easy,” cautioned Jimmie. “We may not be out of the woods yet. Let’s just go along slowly for a while.”
“Aw, go on!” scorned Frank. “What’s there out here to bother?”
“Sure!” chimed in Jack. “We’re away out in the North Sea where we can find nothing but warships and sailing vessels and such!”
“Maybe we might run into the real ‘U-13’,” countered Jimmie. “Then, what would you do if you should meet that fellow?”
“Why, put on steam and run away from him, of course!”
“All right, go ahead if you want to,” submitted Jimmie unwillingly, “but I don’t think it wise. It’s taking considerable risk!”
