"You can get a drink up in the bathroom," his mother told him.

"I don't want this to drink," Ted explained. "I want to fill a glass full of water and set it out on the steps."

"What for?" Janet wanted to know. "No birds will come to drink at night," she added, for she and her brother had made a bird-feeding station in their yard, and also a little shallow basin where the feathered songsters could bathe and drink.

"This isn't for birds," Ted explained. "I just want to set a glass of water outside and wait to see if it freezes. If it does, then we'll know if there's going to be ice on our toboggan slide in the morning."

"Nonsense!" laughed his mother. "I can't let you stay up until you find out if a glass of water will freeze. It would take too long."

"Not to see if just the top froze over," insisted Ted. "I don't mean until the whole glass freezes solid. I know that would take a long time."

"No, no!" laughed his mother, giving him a friendly little push from the room. "Go to bed! I think it will be cold enough to make at least a skim of ice on your toboggan slide. But not much more. So don't be disappointed if you have to use candles on your sled runners to-morrow."

However, Ted, and Janet, and Tom went to bed filled with joyous hopes for the next day. The boys were almost as good as they promised to be, not having any pillow fight. But they did "cut up" a little, and had to be told, more than once, to get quiet and go to sleep. And finally they did.

In spite of the fact that the morning brought Saturday, with no school, when the children might have slept later had they wished, Tom and Ted were up earlier than usual. Hardly stopping to dress properly, the two boys ran out into the yard and to the toboggan slide.

"Hurray!" cried Tom. "She froze!"
