g in at the window. Caleb opened his eyes, and, after lying still
a few moments, began to sing. He thought it was morning, and that it was
time for him to get up. Presently, however, he observed that the sun was
shining in at the wrong window for morning: then he noticed that he was
not undressed; and, finally, he thought it must be night; but he could
not think how he came to be asleep there at that time.

Caleb went out into the parlour. David and Dwight were just putting the
chairs around the tea table. At tea time, the boys talked a good deal
about the mole, and they asked Mary Anna if she would help them rig some
vessels to sail in the Maelstrom.

"Sail in the Maelstrom!" said Mary Anna; "whoever heard of sailing in
the Maelstrom? That is a great whirlpool, which swallows up ships; they
never sail in it. You had better call it the Gulf Stream."

"Well," said Dwight, "we will; and will you help us rig some vessels?"

"Yes," said Mary Anna, "when you get the mole done."

Mary Anna was a beautiful girl, about seventeen years old, with a mild

papers, to make boxes, and portfolios, and little pocket-books, and
wallets of; and she had a paint-box, and pencils, and drawing-books,
and portfolios of pictures and drawing lessons.

She rigged the boys' vessels, and covered their balls, and made them
beautiful flags and banners out of her pieces of coloured silk. She
advised them to have a flag-staff out at the end of the mole, as they
generally have on all fortifications and national works. She told them
she would make them a handsome flag for the purpose.

After tea she went down with them to see the works. She seemed to like
the mole very much. The whirlpool was moving very regularly, and she
advised them to build the mole out pretty far.

"Yes," said Dwight; "and we are going to have a piece across up and down
the stream, at the end of it, so as to make a T of it."

"I think you had better make a Y of it," said Mary Anna.

"A Y!" said Dwight, "how?"

"Why instead of having the end piece go straight across the end of the
mole, let the two parts of it branch out into the stream, one upwards
and the other down."

"What good will that do?" said David.

"Why, if you make it straight like a T, the curre
