The horrid cruelties and outrages that once and a while find their way into the papers — such cases as Prue's, for example — what do they come from? In many cases, it is a gradual hardening process on both sides — the owner growing more and more cruel, as the servant more and more callous. Whipping and abuse are like laudanum; you have to double the dose as the sensibilities decline.
