ked Jan. "If we put wooden windows in we can't see through
'em."

"We can use sheets of ice!" cried Tom. "My father said that that's the
way the Eskimos do up at the north pole. They use ice for glass."

"You can see through ice all right," said Ted. "But where could we get
any thin enough for windows for our snow house?"

"All the ice on the pond and lake is covered with snow," added Lola.

"We can put some water out in pans," went on Tom. "If it's cold to-night
it will freeze in a thin sheet of ice, and then to-morrow we can make
windows of it for our snow house."

"Oh, that'll be fun!" cried Ted.

"It will be almost like a real house!" added Jan.

Mrs. Martin said, when the Curlytops asked her, that Tom's plan might
work if the night turned cold enough to freeze. And as after dark it did
get colder she put some water out in large shallow pans. In the morning
the water was frozen into thin sheets of ice, clear as crystal, and Ted
and Jan could see right through them as well as they could see through
glass.

"They're great!" cried Tom when he saw them, and that afternoon when
school was out, the ice windows were set in the holes in the walls of
the snow house.

"'Dis nice place!" Trouble said, when he was taken out to it. "I 'ikes
it here! I stay all night!"

"No, I guess you won't stay all night," laughed Tom. "You might freeze
fast to the snow bench."

"How plain we can see out of the windows," said Lola. "Oh, see, Ted,
here comes your goat! I guess he's looking for you."

"He must 've got loose and 've run out of his stable," said Teddy. "I'll
go to fasten him up. Here, Nicknack!" he called as he walked out of the
snow house toward his pet.

Nicknack kept on coming toward the white house. He walked up to one of
the windows. The sun was shining on it and as Ted looked he cried:

"Oh, I can see Nicknack in the glass window just as if it was a looking
glass. And Nicknack can see himself!"

This was true. The goat came to a sudden stop and looked at his own
reflection in the shiny ice window. Nicknack seemed much surprised. He
stamped in the snow with his black hoofs, and then he raised himself up
in the air on his hind feet. At the same time he went:

"Baa-a-a-a! Baa-a-a-a-a!"

"Oh, Nicknack's going to buck!" cried Ted.

"Who's he going to buck?" asked Tom, sticking his head out of the
blanket door of the snow house.

"I guess he thinks he sees another goat in the shiny ice window," went
on Ted
