"Fine race, boys! Fine race!" was Fatty Hendry's comment. "Just the same, none of you would have been in it for a minute if I had entered," and at this joke there was a general laugh.

"Say, Fatty, you should have gone into it just to lose flesh," was Andy's dry comment. "If you tried real hard, you might lose a pound a mile," and at this there was another laugh.

The crowd began to gather around Jack and Randy and the others who had won the race, and many wanted to shake hands with the oldest Rover boy. Even some of the town folks skated up, and they were followed by some of the girls from Clearwater Hall.

"I say, boys, this may not be safe!" cried Professor Brice suddenly, when the crowd on the ice had become unusually thick. "This ice isn't as strong as it might be."

"Yes, and with Fatty in the crowd——" began Andy Rover. Then, of a sudden, he stopped short because an ominous crack was heard, followed by several other cracks.

"The ice is breaking!"

"Skate away, everybody, or we'll go down!"

Instantly there was a commotion, and all of the skaters tried to break away from the spot where the crowd had congregated. The confusion was tremendous, and in the mix-up six or eight persons, including Ruth Stevenson and May Powell, were thrown down. Then came another crack, and it looked as if in another instant the ice would give way completely and precipitate the whole crowd into the cold waters of the lake.
