"Danny Rugg--if anybody," answered Bert. "I thought it looked like
him. Probably he heard that we were going to use the boat to go to
Snow Lodge, and he wanted to make trouble for us. He's going to camp
up there near us, I hear."

"Gracious!" cried Dorothy. "I hope he doesn't play any tricks like
that up there."

"If he does I guess Harry and I can attend to him," cried Bert. "But,
in a way, it's a good thing the rope did break or we might have upset.
Only Danny, if he did it, had no idea of doing us a good turn. He just
wanted to make trouble."

"Can you fix it?" asked Nan of her brother.

"Oh, yes, it can be spliced and will be stronger than ever. But I
won't do it now. We can walk the rest of the way to the dock. The wind
is blowing harder than ever, and we don't want any accidents."

Indeed, the wind was blowing a gale now, and even with the sail down
the ice-boat went along at such a speed that it was all Harry and Bert
could do to hold it.

But finally it was gotten to the dock, and made fast, and while the
girls went on to the Bobbsey home to finish with their packing, Bert
and Harry mended the broken rope.

"I'll have to teach Danny Rugg a good lesson," said Bert to his
cousin.
