"D'you really think that power boat we saw is going out to meet a submarine?"
"Ask me an easier one," said Morgan. "I can't guess. But she might. We know very well that German submarines and German raiders, and even Germany itself, pass news back and forth by wireless. We can't control the vibrations of the air—worse luck!"
"Now you've said something, boy!" agreed Torry.
"They read all the news that passes between our ships, too, unless it is in a secret code. And they pick everything they need to know about our ship movements out of the air."
"Too bad wireless was ever invented, then," grumbled Torry.
"Six of one and half a dozen of the other," grinned Frenchy. "You bet our operators steal German messages."
"It's likely. You know that chap on the Colodia whom we all liked so well, the chief wireless operator, got lots of information that was supposed only to be picked up by German submarines.
"In this case," added Whistler Morgan, "the sub may have wirelessed word for supplies. We don't know how many alien enemies may be running wireless stations in the United States. The Secret Service men are unearthing them all the time."
"Well," sighed Ikey, "I only hope we'll catch up with this oil tub we're hunting just as she is unloading her cargo onto a sub. Then! Blooey! We'll drop a depth bomb or two, and settle Mr. Submarine."
"Just like that!" drawled Whistler. "It sounds easy. How many times did the Colodia chase a U-boat and lose it?"
