er needs one. There; put it in your pocket, and see
how it looks."

"You are very kind to me, Mr. Melville," said Herbert, gratefully. "You
couldn't have bought me anything which I should value more."

When Herbert had arranged the watch and chain to suit him, it must be
confessed that it engrossed a large part of his attention, and it was
wonderful how often he had occasion to consult it during the first walk
after it came into his possession.

CHAPTER XVIII. A THIEF IN TROUBLE.

"Have you ever visited the suburbs of Boston?" asked Melville.

"No," answered Herbert. "I know very little of the city, and nothing of
the towns near it."

"Then, as we have time to spare, we will board the next horse car and
ride out to Roxbury."

"I should like it very much, Mr. Melville," said Herbert, in a tone
of satisfaction. I may remark that Roxbury was at that time a separate
municipality, and had not been annexed to Boston.

They did not have to wait long for a car. An open car, of the kind in
common use during the pleasant season, drew near, and they secured seats
in it. After leaving Dover Street, Washington Street, still then narrow,
broadens into a wide avenue, and is called the Neck. It was gay with
vehicles of all sorts, and Herbert found much to attract his attention.

"The doctor tells me I ought to be a good deal in the open air," said
Melville, "and I thought I would act at once upon his suggestion. It is
much pleasanter than taking medicine."

"I should think so," answered Herbert, emphatically.

Arrived at the end of the route, Melville and Herbert remained on the
car, and returned at once to the city. When they reached the crowded
part of Washington Street a surprise awaited Herbert.

From a small jewelry store they saw a man come out, and walk rapidly
away.

"Mr. Melville," said Herbert, in excitement, "do you see that man?"

"Yes. What of him?"

"It is the man who tried to rob me on Bunker Hill Monument."

He had hardly uttered these words when another man darted from the shop,
bareheaded, and pursued Herbert's morning acquaintance, crying, "Stop,
thief!"

The thief took to his heels, but a policeman was at hand, and seized him
by the collar.

"What has this man been doing?" he asked, as the jeweler's clerk came
up, panting.

"He has stolen a diamond ring from the counter," answered the clerk. "I
think he has a watch besides."

"It's a lie!" said the thief, boldly.

"Search him!"
