“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.

“In time, perhaps a farmer may sit before a keyboard in his office and manage tractors plowing and cultivating his fields. Ships of all descriptions will be managed by compass control. And automobiles——”

“I hope Bill Brewster learns to handle his red car by wireless,” chuckled Amy. “It will then be less dangerous to himself and to his friends, if not to pedestrians,” and this quaint idea amused all the Roselawn girls.

CHAPTER XVII—THE TEMPEST

Jessie, Amy, and Nell had spied, on their hike and picnic, an inlet in the shore of the island facing the mainland, on the sands of which were several fish houses and several rowboats and small sailboats that the girls were sure might be had for hire.

“We might have shipped our new canoe down here and had some fun,” Amy said. “That bay is a wonderful place to sail in. Why, you can scarcely see the port on the other side of it. And the island defends it from the sea. It is as smooth as can be.”
