While the girls of Roselawn and their friends found a dozen vacation activities to interest them, the hospital fund committee did not mark time. Mrs. Norwood was away from home almost every afternoon attending meetings and arranging for talent for the great radio concert. Her mother’s absence put upon Jessie’s mind certain responsibilities relating to the household that she usually did not have.

But Jessie was a born housewife. Flyaway Amy knew very little about such things, and she admitted that she dodged all responsibilities of the kind when she could. She preferred to sit on the Norwood porch and knit or read or chat with other girls gathered there while her chum busied herself with these extra duties.

Whenever Jessie was at the radio set, however, Amy was on the spot. During these weeks since first the receiving set had been established in Jessie’s sitting room, the chums had learned a great deal about radio telephony.

“And according to these books and magazines, Jess,” Amy said, “there is going to be something new to learn every day. I don’t see but we shall have to give up almost everything else, if we expect to keep up to date in this science.”

“I suppose there’s bound to be new wrinkles to learn all the time,” admitted Jessie. “But we have got a lot of information about the receiving end of the business. What I am anxious to learn is more about the other end.”

“The sending end?” asked Amy.

“Yes. We did not see much of it that time Mark took us up to the Stratford Company’s sending station, where we met Mr. Blair.”

“Say, Jess!” Amy said suddenly. “Isn’t that funny?”

“Maybe it is. Only I don’t know what you mean,” said her chum, wonderingly.

“That Superintendent Blair’s name should be the same as Hen’s cousin?”
