now seems to be a good long one, and we will drive through the whole
length of it, and you shall look down all the streets that open into it
on the right hand, and I will on the left; and if we see any thing that
looks like our hotel, we will stop."

So they rode on, each boy looking out on his side, until at length they
came to the end of the street, where there was a sort of opening, and a
river. There was a bridge across the river, and an ancient and
venerable-looking castle on the other side of it.

"Ah," said Rollo, "here is the River Tiber."

"How do you know that that is the name of it?" asked Charles.

"Because I know it is the Tiber that Rome is built upon," replied
Rollo,--"the Yellow Tiber, as they call it. Don't you see how yellow it
is?"

As Rollo said this, he made signs for the coachman to turn out to the
side of the street at the entrance of the bridge, and to stop there.
The coachman did as he was directed, and then Rollo and Charles, still
standing up in the carriage, had a fine view of the bridge and of the
river, and also of the Castle of St. Angelo beyond. The water of the
river was quite turbid, and was of a yellow color.

"That's the river," said Rollo, "that Romulus and Remus were floated
down on, in that little ark."

"What little ark?" asked Charles.

"Why, you see," replied Rollo, "when Romulus and Remus were babies, the
story is that somebody wanted to have them killed; but he did not like
to kill them himself with his own hand, and therefore he put them into a
sort of basket, made of bulrushes, and set them afloat on this river, up
above here a little way. So they floated down the stream, and came along
by here."

"Under this bridge?" asked Charles.

"Under where this bridge is now," said Rollo; "but of course there was
no bridge here then. There was no town here then--nothing but fields and
woods."

"And what became of the babies?" asked Charles.

"Why, they floated down below here a little way," said Rollo, "to a
place where there is a turn in the river; and there the basket went
ashore, and was upset, and the children crawled out on the sand, and
began to cry. Pretty soon a wolf, who was in the thicket near by, heard
the crying, and came down to see what it was."

"And did he eat them up?" asked Charles.

"It was not a he wolf," said Rollo; "it was a she wolf--an old mother
wolf. She thought that the children were little wolves, and she came to
them, and lay dow
