The yelp of a sheep dog! She had heard that' often enough to know.

And she rose to change her position so she could command a view of the rocky bluff above.
Presently she espied what really appeared to be a big timber wolf.

But another yelp satisfied her that it really was a dog.

She watched him.
Soon it became evident that he wanted to get down over the bluff.

He ran to and fro, and then out of sight.
