Later children's literature about horses, most notably Black Beauty, does not shy away from cruelty, and leaves readers in little doubt about the miseries of the bearing rein or long and hideous hours of over work. It is strangely shy, though, about gelding. Black Beauty must presumably have been gelded - the vast majority of male horses are - but the subject is simply never mentioned. For Black Beauty, like many of his successors in horse literature, gelding appears to have happened by magic, buried in the blank pages between chapters.
Not so Dick.
