Thinking something had gone wrong, perhaps, with Harry’s skates, Jack kept on, determined to win the medal from Sully, if he possibly could. Sully saw what the real trouble was, but, thoroughly selfish, kept on, hoping to win by accident if not otherwise.

“Help me!” screamed the girl, as she saw Harry approaching. “Help me, Harry Webb!”

“It’s Boxy’s sister, as sure as I live!” cried the boy, in horror. “Keep up, Minnie, and I’ll save you! Catch hold of the ice, and don’t let the current carry you under!”

CHAPTER IV.
A MOMENT OF PERIL.

It was a thrilling moment in Harry Webb’s life when he saw his chum’s sister in her extremely perilous situation.

He well understood how hard it was to keep up one’s courage in that freezing cold water, with the strong current trying its best to drag one under the ice.

“Don’t let go, Minnie!” he shouted, and just then his own voice sounded strange to him. “Hold fast! I’ll be there in another minute!”

With powerful strokes he swept nearer and nearer. The somewhat thin ice bent and cracked beneath his weight, but to this he paid scant heed.

In his pocket, Harry had a couple of skate-straps he had brought along in case anything should happen to his clamp skates. These straps he now buckled together, and wound one end around his hand.

Getting as close to the hole as he dared, he threw out the end of the straps.
