have had a premonition of some tragedy overhanging, since we found the sheep.” “Well, Professor! Hello, Miss Dolly!” called Haynes, as he swung up on a trot. “Are you all right? Better hurry in. There’s a storm coming.” “It is something besides a storm that brought you gentlemen out on a search for us,” said Professor Ravenden shrewdly. “While properly appreciative, I should be glad to have an explanation.” The explanation came swiftly, from the direction of the sea.
