“I know, but Nan and Bert are away down at the other end, with Tommy Todd, and Bert is going to buy hot chocolates.  I know he is, ’cause he said so.  I don’t want to miss them.”

“Me neither!  Wait and I’ll see if I can’t fix your skate, Flossie.”

Freddie was small—­he and Flossie were the smaller pair of Bobbsey twins—­but he was a sturdy little chap, and living out of doors, and playing games with his older brother Bert had taught Freddie how to do many things.  He put Flossie’s skate on her shoe, tightened the strap, and then made it still tighter by putting some pieces of wood under the leather loop.

“There!” he exclaimed, as he stood up, having been kneeling in the snow on the edge of the lake.  “I guess that will hold, Flossie.  Now come on, and we’ll see how fast we can skate.”

Together the brother and sister started off.  This time Flossie’s skate seemed to be all right, needing neither paste nor a postage stamp to hold it on, and in a little while the smaller twins had caught up to Bert and Nan, their brother and sister, who, with a boy neighbor, named Tommy Todd, had slowed up to wait for them.

“What kept you?” asked Nan.  “Did you try to do some fancy skating, Flossie?”

“I guess Freddie stopped to see if there wasn’t a crack in the ice where he could get some water to play fireman,” remarked Bert with a smile, for his small brother was very fond of this game, and his best-liked toy was a small fire engine, which, when a spring was wound, could squirt real water.

“No, I didn’t stop at any cracks!” exclaimed Freddie earnestly.  “Cracks in the ice is dangerous—­Daddy said so.  It was Flossie’s skate.”

“That’s right—­it kept coming off,” explained the blue-eyed girl.  “But Freddie fixed it, and he didn’t have to use a postage stamp, either.  Did you, Freddie?”

“Nope.”

“Well, I guess they know what it means, but we don’t!” laughed Nan, taking her small sister’s hand.  “Come on, now, you little twins.  I We waited for you, so we could all have hot chocolate together.  You didn’t get cold, I hope, stopping to fix your skate, Flossie?”

“Nope!  I’m as warm as butter!”

“What does she mean by that?” asked Tommy Todd.  “I often hear my grandmother say she’s as warm as toast, but butter——­”

“Well, when it’s Winter, like it is now, you have to warm your butter so you can spread it on your bread,” explained Flossie.  “So I’m as warm as butter now.”

“I wish I was!” cried Bert.  “I’m getting a chill standing here waiting for you two!  Come on, now.  Skate lively, and we’ll soon be there,” and he pointed to a little candy and soda-water stand near the lower end of Lake Metoka, on the frozen surface of which the children were skating.

In the little cabin, which in Winter was built over the stand to make a warm place for skaters, hot chocolate and other drinks could be had, and Bert had promised to treat his brother and sisters, as well as Tommy Todd.
