More reporting from a Toronto High School: It's the 1950s now, so most of the "Baby Bags" have graduated. For context, I have just edited an entire page that lists all the citywide athletic championships that the Boys' athletic teams won.
Oh authors with your casual sexism!
When the old auditorium was converted into the Boys’ Gym, the girls inherited the smaller upper gym. The gym rang with giggles and laughter at 3:30 most days while girls played whatever sport was scheduled. The girls’ teams also participated in Hi-Jinks, the Track and Field Days and Cadet Inspection Day. It was a huge honour to be chosen as a cheerleader. It required stamina and quite a bit of athletic ability to do cartwheels and jumps in formation. The Drum Majorettes group was also always popular. The 1952 squad was the largest in any school that year. They performed at the annual Red Feather Tournament of Champions sponsored by the Community Chest (later the United Appeal). It had been organized to raise funds for needy Torontonians. The Majorettes also marched at Varsity Stadium at the City Football Championships and in the Santa Claus Parade.
N.B.: This is the pre-edited version. I'm fixing up the awkward phrasing.
Giggles and laughter! The Boys' teams won citywide championships. The girls giggled and laughed.
