engine running. Willie went on down the
street and was soon in the midst of a throng coming up from the ferry.
He stopped to look at a jeweler's clock, turned about, and started on
his way to rejoin Roy. Suddenly he heard the softly whistled signal of
the wireless patrol. He turned sharply about and saw Captain Hardy
across the street. He dodged a motor-car that was rooming down the
hill and crossed to his captain. There had been no sign of life about
the little house since the grocer's boy came out.

"Come," said the leader. "I have seen the Chief and he is going to
arrange it so that we can watch this place in comfort. We will go back
home now."

They climbed cautiously to the road above. "By George!" exclaimed
Captain Hardy suddenly. "You boys haven't had a bite to eat since
breakfast. I forgot all about that."

"How about yourself?" asked Roy.

"Well, I haven't either, but that's different. I've had a chance to
get something if I had thought of it. We won't wait until we get home
to eat. There's a restaurant at the ferry-house. We'll have a good
dinner there."

More than an hour passed before the three rose from their table.
Another hour had gone by before they reached their headquarters. They
were tired and sleepy. But their drowsiness vanished when Henry rushed
into the living-room of their apartment and thrust a sheet of paper
into Captain Hardy's hands.

"It's another message," he said, "and we deciphered it ourselves."

Captain Hardy stepped to the light and read the message aloud. "Five
more transports sailed late this afternoon. All camouflaged."

"We know the man who sent that message," cried Willie. "We've been
watching him all the afternoon, down on the hillside at Staten Island."

"But this message didn't come from Staten Island," said Henry. "The
detector points straight east over Brooklyn, and the message was sent
from a long way off. It was very faint."

CHAPTER VIII

WHERE MONEY TALKED

For a full minute the members of the wireless patrol stared at one
another in speechless amazement. Then Willie broke the silence.

"I don't care where it came from," he said. "I just know that the man
we were watching sent it."

"But how could he have sent it, when the wireless pointed to Brooklyn?"
demanded Henry.

"Oh! I don't mean that he actually sent it with his own fingers," said
Willie. "But we saw him watching the ships and there isn't any other
place in the
