s there inside the wall?" asked Mr. George.

"O, there are ever so many buildings," said Rollo--"great stone forts,
and barracks, and bastions, rising up one above another, and watch
towers on the angles of the walls. I can see one, two, three watch
towers. I should like to be in one of them. I could look over the whole
city, and all the country around.

"I can see some portholes, with guns pointing out,--and--O, and now I
see a monstrous great gun, looking over this way, from one of the
highest platforms. I believe it is a gun."

"I suppose it must be Mons Meg," said Mr. George.

"Mons Meg?" repeated Rollo. "I'll get a glass and see."

"Yes," said Mr. George. "There is a very famous old gun in Edinburgh
Castle, named Mons Meg. I think it may be that."

"I can't see very plain," said Rollo, "the air is so thick with the
rain; but it is a monstrous gun."

Just at this time the waiter came into the room to ask the party if they
would have any thing to eat.

"Yes," said Mr. George, "we will. Go down with the waiter, boys, and see

So the boys went down, and in fifteen minutes Mr. George followed. He
found the supper table ready in a corner of the coffee room, and Rollo

"Where is Waldron?" asked Mr. George.

"He's gone to the circulating library," said Rollo.

"He has gone to get a book about the history of Scotland," said Rollo.
"We have been reading in the guide book about the castle, and Waldron
says he wants to know something more about the kings, and the battles
they fought."

"How does he know there is any circulating library?" asked Mr. George.

"He asked the waiter," said Rollo, "and the waiter told him where there
was one. He said he would try to be back before the supper was ready,
and that we must not wait for him if he did not come."

"He ought to have asked me if I was willing that he should go," said Mr.
George.

In a few minutes Waldron came in with two pretty big books under his
arm. They were covered with paper, in the manner usual with the books of
circulating libraries. Waldron advanced to the supper table, and laid
the books down upon it with an air of great satisfaction.

"Then you found a circulating library," said Mr. George.

"Yes, sir," said Waldron, "and I have got two volumes of the history of
the great men of Scotland."
