asked Mr. George.

"Two pounds and two pennies," said Rollo, "and your due bill for four
shillings."

"Are you sure you did not leave it at home?" asked Mr. George.

"Yes," said Rollo. "I have not taken it out since this morning. I looked
it over this morning and saw all the money, and I have not had it out
since."

"Some people think they are sure when they are not," said Mr. George. "I
think you will find it when you go home."

Rollo was then anxious to go home at once and ascertain if his purse was
there. All his interest in seeing the illumination was entirely gone.
Mr. George made no objection to this; and so, turning off into a side
street in order to escape from the crowd, they directed their steps,
somewhat hurriedly, towards their lodgings.

"I _know_ we shall not find it there," said Rollo, "for I am sure I had
it in my pocket."

"It is possible that we may find it," said Mr. George. "Boys deceive
themselves very often about being sure of things. It is one of the most
difficult things in the world to know when we are sure. You may have
left it in your other pocket, or put it in your trunk, or in some
drawer."

"No," said Rollo; "I am sure I put it in this pocket. Besides, I think I
felt the robber's hand when he took it. I felt something there, at any
rate; and that reminded me of my purse; and I thought it would be best
for me to give it to you. But when I went to feel for it, it was gone."

Mr. George had strong hopes, notwithstanding what Rollo said, that the
purse would be found at home; but these hopes were destined to be
disappointed. They searched every where when they got home; but the
purse was nowhere to be found. They looked in the drawers, in the
pockets of other clothes, in the trunk, and all about the rooms. Mr.
George was at length obliged to give it up, and to admit that the money
was really gone.

CHAPTER XIII.

PHILOSOPHY.

Mr. George and Rollo held a long conversation on the subject of the lost
money while they were at breakfast the morning after the robbery
occurred, in the course of which Mr. George taught our hero a good deal
of philosophy in respect to the proper mode of bearing such losses.

Before this conversation, however, Rollo's mind had been somewhat
exercised, while he was dressing himself in his own room, with the
question, whether or not his father would make up this loss to him, as
one occasioned by an accident. You will recollect that the arrangement
