Read the passage from "The Lady, or the Tiger.” The institution was a very popular one. When the people gathered together on one of the great trial days, they never knew whether they were to witness a bloody slaughter or a hilarious wedding. This element of uncertainty lent an interest to the occasion which it could not otherwise have attained. Thus, the masses were entertained and pleased, and the thinking part of the community could bring no charge of unfairness against this plan, for did not the accused person have the whole matter in his own hands?
