The ascension of the gas balloon "University City" was the final event at the American Woman's League Convention. The balloon was piloted by Captain John Berry who took off from a field just west of the Woman's National Daily Building. A photograph taken just before the balloon launched appeared in "The Woman's National Daily" on June 14, 1910.
