"Well, try it, Youngster. And, Tug, suppose you take a scout in the other direction."

Tug went off, but soon returned, reporting a worse instead of better appearance, and Aleck, who had climbed over, came back to say that the ridge was about twenty-five yards wide.

"How does it look?" asked Katy.

"Why, it looks as though a lot of big cakes of ice had been piled up on edge, and then frozen into that rough shape, or lack of shape. I should say the ridge is ten feet high in the middle, and on the other side it is a straight jump down for about six feet. But it's worse everywhere else. We must take our skates off the first thing."

This done, they stood up, ready to drag the boat as near to the hummock as possible. But it was hard pulling, for the slope was pretty steep and rough.

"Where's that Jim, I wonder?" cried Aleck. "I'll teach The Youngster not to run off the minute any work is to be done. Jim!"

But no boy answered the call, nor several others. Tug stood up on the boat, and Katy climbed to a high point of ice, but neither could see anything. Then they all became alarmed, fearing he might have fallen into one of those holes that here and there are found in the thickest ice, and always stay open. It is an easy matter to skate into one, but a very hard one to get out again. It was the thought of this that made Katy run in the direction whither Jim had started, but her brother called her back.

"Wait, Katy. We'll put on our skates. Probably The Youngster's hiding, and I'll box his ears when I catch him. This is no time for fooling."
