Sagacity

There is danger at this place which the horse can see, but which the
rider fails to detect. They are in the midst of a swamp where one false
step would mean a horrible death in the quagmire on the verge of which
the horse has pulled up. The man uses whip and spur, but the horse
refuses to move. Finally the rider leaves the horse to himself to find a
way round which brings them both to safety.
