“For pity’s sake, Henrietta!” cried Jessie. “Where is this island?”

“Where would it be? Out in the water, of course. There’s water all around it,” declared the freckle-faced child in vigorous language. “Don’t you s’pose I know where an island ought to be?”

At that Amy Drew burst into laughter. In fact, Jessie Norwood’s chum found it very difficult on most occasions to be sober when there was any possibility of seeing an occasion for laughter. She found amusement in almost everything that happened.

But that made her no less helpful to Jessie when the latter had gained her first interest in radio telephony. Whatever these two Roselawn girls did, they did together. If Jessie planned to establish a radio set, Amy Drew was bound to assist in the actual stringing of the antenna and in the other work connected therewith. They always worked hand in hand.

In the first volume of this series, entitled “The Radio Girls of Roselawn,” the chums and their friends fell in with a wealth of adventures, and one of the most interesting of those adventures was connected with little Henrietta Haney, whom Amy had just now called “O-Be-Joyful” Henrietta.

The more fortunate girls had been able to assist Henrietta, and finally had found her cousin, Bertha Blair, with whom little Henrietta now lived. By the aid of radio telephony, too, Jessie and Amy and their friends were able to help in several charitable causes, including that of the building of the new hospital.

In the second volume, “The Radio Girls on the Program,” the friends had the chance to speak and sing at the Stratfordtown broadcasting station. It was an opportunity toward which they had long looked forward, and that exciting day they were not likely soon to forget.

A week had passed, and during that time Jessie knew that little Henrietta had been taken to Stratfordtown by her Cousin Bertha, where they were to live with Bertha’s uncle, who was the superintendent of the Stratford Electric Company’s sending station. The appearance of the wildly excited little girl here in Roselawn on this occasion was, therefore, a surprise.

Jessie Norwood seized hold of Henrietta by the shoulders and halted her wild career of dancing. She looked at Montmorency Shannon accusingly and asked:

“Do you know what she is talking about?”
