Monroe’s pet name has been changed from the “Queen City” to the “Parlor City of the Ouachita,” at the suggestion of a correspondent in the last issue of the Telegraph-Bulletin, of this place, who says:
 
“The State of Louisiana is an immense building, composed of many rooms, the towns and cities within her border recognized as those compartments. Monroe is recognized as the healthiest, neatest, best laid out, most progressive town in the State, with the most brilliant future before it.
 
“The location is excellent, her citizens are liberal, progressive and hospitable, therefore, in view of these facts, I nominate Monroe as the “Parlor City of Louisiana” and respectfully submit the title for the approval of her progressive citizens.”
