The King now opened the door in the top of the cylinder and the girl stepped inside. The space was just big enough to permit her to lie down comfortably, and the bottom of the cylinder had been thickly covered with soft cushions brought from the palace.

When the King had closed and fastened the door, he gave a signal to the four-and-twenty beavers, and at once they dashed into the water, drawing the glass submarine after them, and began swimming with powerful strokes down the river. They swam well under the surface of the water, and the glass boat followed them without either touching the bottom or rising to the top.

At first the Princess was much bewildered by her strange journey, for it seemed as if the water was pressing upon her from all sides. But presently she realized that she was quite safe in the glass tube, and began watching curiously the pretty weeds and water-flowers that grew at the bottom of the river, and the queer fishes that swam around her.

The speed of the swimming beavers was surprising. It was not long, indeed, before they reached the mouth of the river and swam boldly out into the sea. Jacquelin had no idea of the direction they took, but she trusted to the wisdom of her friend the Fairy Beaver, and was not at all frightened.

And now the sights that she saw were very strange indeed; for the seaweeds were of most gorgeous hues, and there were not only big and little fishes of every description, but brilliant sea-anemones and jelly-fish floating gracefully on all sides of her.

The journey was long, but not at all tiresome, and the girl had not realized how far she had been drawn through the waters of the ocean when a dark gray object appeared just overhead, and the beavers came to a halt.

Slowly the glass cylinder rose to the surface of the waves, and Jac saw just beside her the boat containing her parents. The girl's mother also saw, to her great surprise and joy, the form of her daughter lying in the glass case, and at once unfastened the door and assisted the child to crawl out and scramble into the boat.
