It was the custom of the girls to repair to the gymnasium after dinner for a half hour's frolic. Usually they danced.
Blue Bonnet and Carita followed the other girls down-stairs and through the narrow passage that connected the two buildings, a passage known as the subway—or sub.

Mary Boyd drew the girls over to a door at one side of the gymnasium and flung it wide.
"That's a part of the furnace room," she said. "You can go through here and follow another little dark hall—oh, much worse than this—and it takes you to the kitchen and pantries. We went down one night last year—"

Carita shuddered.
"Yes, it was loads of fun. There were five or six of us. We ate enough apple sauce and fresh bread to kill us."
At the piano in the gymnasium a girl was playing a two-step.
