You may be sure Hal and Mab did not want to go to bed, even if they were sleepy. They wanted to stay up and watch the water in the bottle freeze. But Mamma Blake soon had them tucked snugly under the covers.

Then Daddy Blake fixed the furnace fire for the night, as it was getting colder and colder. Next he opened a package he had brought home with him. Something inside jingled and clanked, and shone in the lamplight as brightly as silver.

"What have you there?" asked Aunt Lolly.

"That's the children's secret," answered Daddy Blake, as he wrapped the package up again.

Hal was up first in the morning, but Mab soon followed him.

"Daddy, where is the bottle?" called Hal.

"May we get it?" asked Mab.

"Oh, it is much too cold for you to go out until you are warmly dressed!" cried Daddy. "I'll bring the bottle in so you can see it."

He went out on the porch in his bath robe and slippers, and quickly brought in the bottle of water he had set out the night before.

"Oh, look!" cried Hal.
