Labor organizer Mary Harris “Mother” Jones led the “March of the Mill Children” over 100 miles from Philadelphia to Pres. Theodore Roosevelt’s Long Island summer home in Oyster Bay, New York, to publicize the harsh conditions of child labor and to demand a 55-hour work week. It is during this march, on about the 24th, she delivered her famed “The Wail of the Children” speech. Roosevelt refused to see them.
