"But I don't know how to do puzzles. I never saw one like this."

"If you knew how to do it, it wouldn't be a puzzle. I don't know either; but we'll learn."

"I'll show you how to begin," said Miss Hart. "Wait a minute."

She went out to the dining-room, and returned with two trays, oblong, square-cornered and of fairly good size.

"Make your puzzles on these," she said, "and then you can carry them around while working on them, if you want to. You can't do that, if you make them right on the table."

So with the trays on the table in front of them the girls began. Each puzzle had about a hundred and fifty pieces, and they were not easy ones. Miss Hart showed them how to find pieces that fitted each other; but would not help them after the first two or three bits were joined, for she said the fun was in doing it themselves.

"But I can't!" said Midge, looking perfectly hopeless; "these pieces are all brownish and greenish and I don't know what they are."

"I see," said Delight, her eyes sparkling; "you must find a face, or something that you can tell what it is, and start from that."

"But there isn't any face here," said Midget; "here's one eye,—if it is an eye!"
