“Oh! The yacht that sailed yesterday! Yes, she carried antenna.”

“And she carried Doctor Stanley and Miss Nell Stanley, too, besides the boys, Mr. Darry and Mr. Burd,” said Henrietta. “Then they can hear you?”

“If they know how to use the wireless they could catch a signal from this station.”

“Miss Jessie knows all about radio,” said Henrietta. “She made it.”

“Oh, she did?”

“Yes. She made it all up. She and Miss Amy built them one at Roselawn. That was before Montmorency Shannon built his. Well, Miss Jessie is out there on the Marigold.”

“So I understand,” said the much amused operator.

“I wish you would—please—send her word that I’d like to have her come back to my island.”

“Are you the little girl who owns this island? I’ve heard about you.”

“Yes. But there ain’t much fun on an island if your friends aren’t on it, too. And Miss Jessie is one of my very dearest friends.”
