"They seem to have headed for the west. We are sure of that much,"
decided Ned.

"Which means nothing at all," answered Tad. "They may have turned and
gone back or else are traveling along ahead of us. In either case we
can't follow them. Do you not think we had better be starting,
Professor? We cannot afford to lose a minute now. I want my pony."

"And so do I--and I--and I," added the lads, one after the other.

"I think so. Yet how are we going to find our way? We shall be
lost."

"No, we can't get lost, Professor," interrupted Stacy.

"Not lost--cannot get lost?"

"No."

"Why not?" glared the Professor.

"We can't get lost," announced Stacy impressively, "because we don't
know where we are, anyway."

A roar of laughter greeted this assertion. It did more than anything
else to put the boys in a better frame of mind--unless perhaps it
might have been the return of the lost ponies.

"I am forced to admit the correctness of Master Stacy's logic,"
replied the scientist, after their laughter had subsided.
