lace on the East coast. Perhaps they've got some way there of
signalling to ships at sea. Anyhow, that's what's got to be discovered. Did
you see Graves to-night?"

"No," said Dick, his lips tightening, "I didn't! But I heard about him, all
right."

"How? What do you mean?"

"I heard that he'd been doing a lot of talking about you. He said it wasn't
fair to have taken you and given you the honor of doing something when
there were English boys who were just as capable of doing it as you."

"Oh!" said Harry, with a laugh. "Much I care what he says!"

"Much I care, either!" echoed Dick. "But, Harry, he has made some of the
other chaps feel that way, too. They all like you, and they don't like

"Well, it's not my fault," said Harry, cheerfully. "I certainly wasn't
going to refuse. And it isn't as if I'd asked Mr. Wharton to pick me out."

"No, and I fancy there aren't many of them who would have done as well as

"Good-night, Dick!"

gave them their orders.

"I've requisitioned motorcycles for you," he said. "Make sure of the
location of the house, so that you can mark it on an ordnance map for me.
Then use your own judgment,--but find the next house. I have had letters
prepared for you that will introduce you to either the mayor or the
military commander in any town you reach and you will get quarters for the
night, if you need them. Where do you think your search will lead you,
Fleming?"

He eyed Harry sharply as he asked the question.

"Somewhere on the East coast, I think, sir," replied Harry.

"Well, that remains to be seen. Report by telegraph, using this code. It's
a simplified version of the official code, but it contains all you will
need to use. That is all."

Finding the house, when they started on their motorcycles, did not prove as
difficult a task as Harry had feared it might. They both remembered a
number of places they had marked from the cab windows, and it was not long
before they were sure they were drawing near.

"I remember that hill," said Harry. "By Jove--yes, there it
