The subject is cruelty to animals through the ages. It sweeps from the Colosseum to the Chicago stockyards. It discusses the ethics of feeding geese to swell their livers a hundredfold, animals caponized, forcefed, kept in sweat-boxes, artificial twilight and inhumane slaughtering. The author also looks into the horrifyingly unsportsmanlike methods present in big game hunting and such matters as ladies' fashion which can demand coats that require a hundred minks to die agonized deaths in traps. Altogether unsettling even if it is written in non-sensational style, this book is intended to win converts to a code of humanity toward animals.
