troll about the place
carelessly. There is British spy watching my movements and I wish to
watch him and, if possible, to catch him. The man is short and rather
stout and had a red face. There is another, who may not join him at
once, who wears a black suit and a steeple-crowned hat and has a beard.
He will send the other one first, I think."

"All right, Captain," replied the boy, whose name was Ben Spurlock. "We
will watch him. Come along, Sam."

Dick had gone on, meanwhile, the boys proceeding in couples or singly to
the church, where they scattered about waiting further instructions from
the young captain. Bob appeared at the Bowling Green at the appointed
time, and said:

"The fellow was cautious and did not follow me, but I suppose he will be
at the church."

"Probably, as his instructions were to follow me. Did he stay as long as
you did?"

"Yes, and remained after I left. You will see him at the church, no
doubt. The other man may be there. Come into the nearest tavern and
exchange coats with me. We will see if these men are observant or not."

"Very good," laughed Bob.

In the private bar of the tavern the boys were alone long enough to make
the exchange, and then Dick sent Bob ahead and told him to wait in the
churchyard for him or some one wearing his own uniform.

"You are the captain now, Bob," with a laugh, "but I don't know who will
be the lieutenant yet. That will depend."

Dick then went over to Stone street, where he entered a little shop kept
by a draper, to whom he said:

"I want an ordinary suit of clothes, Mr. Towns. I am watching a spy and
I think it just as well not to be in uniform."

"I see, Captain. You are wearing the lieutenant's coat now."

"You are very observant," smiling. "I will leave it here and send one of
the boys for it."

"Very good, Captain. Step into the wareroom and take what you wish."

The wareroom was no bigger than the shop, but the different suits were
hanging about the sides, and Dick quickly selected one not likely to
attract much attention, and put it on, leaving the uniform behind. On
Whitehall street Dick met one of the boys, Phil Waters by name, and
directed him to go to the draper's and put on Bob's coat over his own,
the young lieutenant being of a heavier build. As Phil did not have his
musket with him, the change was easily effected, and no one not knowing
him would suspect that he was not the lieutenant.

"Go and meet Bob," Dick said, "and talk
