together in high glee.

At last, when they had somewhat cooled down, Wabi said:

"That John Ball was a pretty poor fellow at a guess, eh? What do you
say, Rod?"

"Or else pretty clever," added Rod. "By George, I wonder if he had a
reason for making his scale fifty miles or so out of the way?"

Wabi looked at him, only partly understanding.

"What do you mean?"

"I mean that our third waterfall is more than likely to be mighty
close to this one! And if it is--well, John Ball had a reason, and a
good one! If we strike the last fall to-morrow it will be pretty
good proof that he drew the map in a way intended to puzzle
somebody,--perhaps his two partners, who were just about to start for
civilization."

"Muky, how far have we come?" asked Wabigoon.

"T'ree time first fall," replied the old Indian quickly.

"A hundred and fifty miles--in three days and one night. I don't
believe that is far out of the way. Then, according to the map, we
should still be a hundred miles from the third fall."

"And we're not more than twenty-five!" declared Rod confidently.
