The Radio Girls of Roselawn by Margaret Penrose

Parkville was reached within a short time. It was still early evening. The girls from Roselawn and their host and hostess found a number of neighbors already gathered in the drawing-room, to listen to the entertainments broadcasted from several radio stations.

They were too late for the bedtime story; but from the cabinet-grand, like an expensive talking machine, the slurring notes of a jazz orchestra greeted their ears as plainly as though it were coming from a neighboring room instead of a broadcasting station many miles away. Amy confessed that it made her feet itch. She loved to dance.
