The reason for visiting stables and kennels (see Chap. Ill, 
p. 5) is : that of all the various species of animals that 
mankind has kept alive in conditions differing from those of 
nature there are two species — the horse and the dog — on 
the care of which the human intellect has been specially 
exercised from century to century for untold thousands 
of years, and therefore the director of a zoological garden 
should be always on the alert to learn from the experiences 
of the horse-master and the kennel-man facts that may prove 
useful in the management of less known animals.
