University women began a May Day tradition in 1909. 

Known as "McMillan Day," the festivities included dramatic presentations and a dance to wind ribbons around the maypole outside the women's dorm (McMillan Hall). 

Junior and senior women, coordinated by the Women's Athletic Director, selected the "May Fetes." Student Life in 1937 reported that the honorees were selected based on, "Interest, Enthusiasm, Activities, Popularity, [and] Appearance," with one to be the May Queen.  

The annual tradition continued until 1943, when Athletic Director Alice Schriver announced it was cancelled so, "women students could use their time for Red Cross and other war activities on campus."
