" I long ago lost a hound, a bay horse, and a turtledove, and am still on their trail.  Many are the travelers I have spoken concerning them, describing their tracks and what calls they answer to.  I have met one or two who had heard the hound, and   the tramp of the horse, and even seen the dove disappear behind a cloud, and they seemed as anxious to recover them as if they had lost them themselves."
