"I was practising on my bed this morning," said Jean. "Cissie and Maggie showed me the strokes. It's really rather like what a frog does, isn't it?"

"Come along; I can't waste time," said Miss Latimer. "I can give you each one more turn with the lifebuoy, and then I shall expect you to hold one another up, and try by yourselves."

By the third lesson Patty had improved so much that she was able to manage without assistance, and Miss Latimer declared that she must swim the entire length of the bath alone, from the steps to the deep end. All the class stopped floating and diving, and sat down on the edge to watch her, so that it was somewhat of an ordeal to have to perform her feat before a row of laughing eyes. She did very nicely, indeed, in the shallow part, where she could put a surreptitious foot to the bottom; but when it came to the middle, and all had to depend upon her aquatic skill, she grew nervous.

"Go on, Patty, you're all right!" called Enid.

"Throw your neck back!" cried Miss Latimer.

"Go on, Patty, keep it up!"

"Don't be done, Patty!"

"She's going under!"

"No, she's not!"

"Keep at it, Patty!"
