Mrs. Fergus laughed softly. "You'd let them do anything, Dick,—stick pins into you—"

"If it would be any fun for them," said Captain Fergus gruffly, "I guess I could stand it. What's a pin anyway?"

Mrs. Fergus laughed again. "You'd find out. But I was really thinking of the difference in the girls. Elizabeth is naturally considerate, Olivia is not. Olivia is a good swimmer, of course, and she is pretty and sweet and attractive, but she has done some outrageous things in the last three years. Nothing bad, but absolutely inconsiderate." She was talking to us now more than to her husband. "She swims so well that she jumps in—or she used to—whenever she feels like it, clothes and all. Why, she even took her mother's parasol in with her one day. It ruined the parasol, of course. She was all dressed up for a party, and had on a lovely dress, with a beautiful old ribbon sash, which was spoiled. Luckily her dress was a wash dress, but it had to be done up again, and the Greshams had no money to waste." She broke out in sudden laughter. "But it was funny, Dick, to see her swimming about, holding the parasol. Do you remember? At sixteen Olivia Gresham was just a pirate, and she is more or less of one at eighteen. Look at Jack Ogilvie and the way she treats him, and he as nice a boy as ever lived."

"You may look at Jack Ogilvie now," said Captain Fergus quietly, "if you will raise your eyes. There he comes."

Accordingly we raised our eyes, all of us, and we saw nothing but those two tiny sails that I have mentioned, almost in the same place in which they had been for the last half hour; and a motor-boat, almost hidden in the haze and very difficult to make out, seeming to be soaring over the tops of the waves toward us. It must have been five miles away.

"But, Dick," said Mrs. Fergus, "where is Jack? Is he—"

"In that motor-boat. Don't you see it? Head on."

He whistled shrilly. The launch had been lying idly before us, her engine stopped, and Miss Radnor sat upon the deck with her feet dangling over the side. At the whistle she glanced down the bay, then looked around at us and waved her hand. Then she simply straightened out and slipped into the water feet first, and disappeared.

"Captain Fergus," asked Eve, "how can you possibly tell who is in that boat? I can hardly see the boat."
