“Well, that’s good-night for her,” said Mr. Brown. “Ready, that operator certainly had a right to have a case of rattles.”

“Was she a fine boat?”

“A beauty.”

“Ever see her?”

“Yes, once in New York harbor. The old man was coming back from a cruise to the Azores. That’s a favorite stamping ground of his, by the way. There’s nothing cheap about J. J. when he comes to gratifying his own whimsies, and the Halcyon was one of them. Mahogany, velvet, mirrors, and I don’t know what all,—but never mind that now. We ought to be sighting some of the boats.”
