It brought her a furious sense of being lost.

Over there ought to be the familiar way where the cabin stood, but there was no sign of anything she had ever seen before, though she searched eagerly for landmarks.

The course she had chosen, and which had seemed the only one, would take her straight up, up over the mountain, a way well-nigh impossible, and terrible even if it were possible.
It was plain she must change her course, but which way should she go?
She was completely turned around.

After all, what mattered it?
One way might be as good as another, so it led not home to the cabin which could never be home again.

Why not give the horse his head, and let him pick out a safe path?
Was there danger that he might carry her back to the cabin again, after all?
Horses did that sometimes.
