I’ve covered this topic before: children chained up like animals. It was certainly a major problem in the past, and one that we don’t hear about all that often today (although it does still happen.
The story below was published 100 years ago, in 1924, and is a brief report of abuse.
Child Chained by Neck. Key in Father’s Pocket
NIAGARA FALLS, N.Y., December 29, 1924. — Joseph Zienski was arrested last night, charged with having kept his daughter, 12 years old, chained for several days.
The police say the chain was about 5 feet long, and was fastened around the child’s neck with a padlock, the key of which the father carried in his pocket.
