he spoke to any of them; but he pointed out the several
kinds,--policemen, firemen, messenger-boys, loafers, brokers,
post-office carriers, a dozen more, with a degree of confidence which
fairly astonished his friends.

"I could learn to tell all of them that wear uniforms, myself," said
Dabney; "but how do you know the others?"

"How do I know 'em? Well, it's just like knowing a miller or a
blacksmith, when you see him. They all have some kind of smut on them
that comes from their trade."

There may have been something in that, or it may be barely possible that
Ford now and then mixed his men a little, and pointed out brokers as
"gamblers," and busy attorneys as probable pickpockets. He may have been
too confident.

On they went, till the brains of all but Ford and Frank were in a sort
of whirl. Even Dab Kinzer was contented to look without talking; and
Dick Lee, although he had not a word to say, found unusual difficulty in
keeping his mouth shut. It positively would come open, every time Ford
pointed out another big building, and told him what it was.

They were not travelling very fast, but they were using a good deal of
time in all that sight-seeing; and walking is hungry business, and a few
raw oysters could not last six hearty boys very long.

"I say, Ford," sung out Joe from the rear, "isn't it getting pretty near
time for us to think of getting something to eat?"
