“Mind she doesn’t get on another rock, Leslie,” he cried.

“Here, catch hold of this,” cried Pradelle, whose face was ashy, and he held out the boat-hook as far as he could reach.

“Thank ye,” said Harry mockingly, and twenty yards away. “Little farther, please. What a lovely day for a swim!”

“Harry, pray come into the boat,” cried Louise excitedly.

“What for? Mind the porpoise.”

He gave a few sharp blows on the water with his hands, raising himself up and turning right over, dived, his legs just appearing above the surface, and then there was an eddy where he had gone down.

“Don’t be frightened,” whispered Madelaine, whose voice sounded a little husky.

“Here we are again!” cried Harry, reappearing close to the boat and spluttering the water from his lips, as with all the gaiety of a boy he looked mirthfully at the occupants of the boat. “Any orders for pearls, ladies?”

“Don’t be foolish, Harry,” said Louise, as he swam close to them.

“Not going to be. I say, Leslie, take the boat-hook away from that fellow, or he’ll be making a hole in the bottom of the boat.”
