for miles and miles. Strange-looking sea animals crawled close to
the rushing train. If they came too close the suction of the water
drew them along until they disappeared beneath the car.

As darkness settled down over the quiet deep, Mary Louise turned from
the window with a sigh. "I feel sleepy already," she said, "and
it's only supper time!"

"We'll tell the porter to make up our berths," said the Mermaid
Princess. He can do it while we are having our supper in the dining
car."

On their return they found their berth in readiness. Soft green seaweed
curtains hung gracefully to the floor, one of them being drawn aside,
showing a little white bed. It looked as comfortable as her own little
bed at home, Mary Louise thought.

It took the two little mermaids but a few minutes to undress, and as
soon as their tired heads touched the pillow they were sound asleep.

Softly the seabells are ringing away,
Dipping and dripping and white with the spray,
Ding-dong, and ding-dong, and ding-dong, so deep,
The seabells are singing me softly to sleep.

Over and over again in her dreams little Mary Louise repeated this
song. Then suddenly the bells seemed to change their tune. They
clanged out wildly until a sudden loud crash awoke her with a start.
The engine whistle was sending forth loud, warning cries. The Mermaid
Princess began to tremble with fright.
