pposite as
soon as he saw the fellow.

Turning into Broad Street, the boys walked down and at once the spy, if
he were one, took the same direction. Fraunces tavern, on the corner of
Broad and Pearl streets, was at that time a great resort for army
officers and men-about-town, and was, therefore, just the place which
the boys would frequent. Crossing the street when they reached Pearl
street, the boys went into the tavern, and were shortly followed by the
man in the steeple-crowned hat, who took a seat at a table near enough
to understand all that they said.

Giving Bob a wink, Dick began talking about some supposed exploit with
some one in the army, and went on from that to telling of meeting
certain beautiful young ladies, and how the latter were so charmed with
him and other boastful talk. The man was evidently greatly disgusted at
having to listen to such talk, as he had evidently expected to hear
something different, and he shortly moved his seat to another part of
the room.

"He had no interest in hearing how Polly Perkins winked at you, Dick,"
laughed Bob.

"No, but he wants to find out more about us, nevertheless. Don't look

The man was drinking strong ale from a pewter and, having finished it,
set the pewter down. Dick saw him scratch something on it and beckon

man came forward, picked it up and set it on the table, but Dick could
see that he glanced at it at the same time, and then, as if upon a place
to sit, came toward them and sat three or four tables away. The
suspected spy presently arose and went out and Dick said:

"Well, good-by, Bob. I will meet you at Trinity church in half an hour."

Then muttering the words, "Bowling Green, ten minutes," he walked away,
going past the table where the man with the steeple-crowned hat had been
sitting and carelessly knocking off the pewter. Picking it up, he looked
at it and saw scratched on one side: "Follow Slater."

"So, this is another, as I supposed," he thought. "There are several
spies in town, and they know me and are trying either to learn something
or to get possession of me. We shall have to turn the tables on them."

He made his way to the Bowling Green, meeting on the way four or five of
the Liberty Boys.

"Go up to Trinity church, boys," he said, "s
