Colonel Zack Mulhall, general livestock agent of the Frisco road, accompanied by his two daughters, Misses Lucille and Flossie, arrived this morning and they are guests of the Sheldon. Colonel Mulhall was seen this afternoon by a Herald man and announced that Miss Lucille would enter the roping contest at Washington park tomorrow, but the hour is not known. It will be in the afternoon, however, as the convention will be in session in the morning and it is desired to have Miss Mulhall rope when everybody can get out to see her. Her two favorite ponies have arrived by express. This will be her first appearance on the roping field since she was injured at St. Louis last October.
