andy to
know what they were talking about."
"There's the other station answering!" said Dick, excitedly, after a
moment. "Isn't it lucky that it's such a fine day, Harry? See--there it is,
over there!"
"Let me have the glasses," said Harry, taking the binoculars from Dick.
"Yes, you're right! They're on the top of a hill, just about where I
thought we'd find them, too. Come on! We've got no time to waste. They're a
good seven miles from here, and we've a lot more to do yet."
Below stairs the old gentleman tried to stop them. He was very curious by
this time, for he had been thinking about them and it had struck him that
they were too much in earnest to simply be enjoying a lark. But Harry and
Dick, while they met his questions politely, refused to enlighten him.
"I'm sorry, sir," said Harry, when the old gentleman pressed him too hard.
"But I really think we mustn't tell you why we're here. But if you would
like to hear of it later, we'll be glad to come to see you and explain
everything."
"Bless my soul!" said the old man. "When I was a boy we didn't think so
much of ourselves, I can tell you! But then we didn't have any Boy Scouts,
either!"
It was hard to tell from his manner whether that was intended for a
compliment or not. But they waited no longer. In a trice they were on their
motorcycles and off again. And when they drew near to the hilltop whence
the signals had come, Harry stopped. For a moment he looked puzzled, then
he smiled.
"I think I've got it!" he said. "They're clever enough to try to fool
anyone who got on to their signalling. They would know what everyone would
think--that they would be sending their messages to the East coast,
because that is nearest to Germany. That's why they put their first station
here. I'll bet they send the flashes zig-zagging all around, but that we'll
find they all get east gradually. Now we'll circle around this one until we
find out in what direction it is flashing, then we'll know what line we
must follow. After that all we've got to do is to follow the line to some
high hill or building, and we'll pick up the next station."
Their eyes were more accustomed to the work now, and they wasted very
little time. This time, just as Harry had guessed, the flashes were being
sent due east, and judging from the first case that the next station would
be less than ten miles away, he decided to ride straight on for about that
distance. He had a road map, and found tha
