"Oh! Oh! That's me!" gasped Henrietta. "How'd he know me?"
"So I have to warn Henrietta, the little girl I speak of, that there is a lot she must do if she wishes in time to enjoy the wealth which she expects."
At that the other children began to exclaim. It was Henrietta. They almost drowned out the first of the bedtime story with their excited voices.
"Well," exclaimed Henrietta, "I guess everybody knows about my owning this island, so that Ringold one needn't talk! But Miss Jessie's mother told me what I had got to do to deserve my island."
"What have you got to do?" asked Amy, curiously. "The Radio Man says you must be good."
"Miss Jessie's mother says I've got to make folks love me or I won't enjoy my island at all—so now. But," she added confidentially, "I don't believe I ever shall want that Ringold one and Sally Moon to love me. Do you s'pose that's nec-sary?"
After the children had gone the older girls discussed a point that Amy brought up regarding the incident. Of course, Amy was in fun, for she said:
"Listen! Didn't I read something about 'radio control' in one of our books, Jess? Well, there is an example of radio control—control of children. Henrietta is going to remember that she is on the Radio Man's list. She'll be good, all right!"
Mr. Norwood laughed. "How do we know what great developments may come within the next few years in the line of radio control? Already the control of an aeroplane has been tried, and proved successful. A submarine may be governed from the shore. The drive of a torpedo has already been successfully handled by wireless.
