Both Allan and Rory knew well that their friend could swim, and the latter at all events seemed to treat the affair as a very pretty piece of entertainment.

“Man overboard?” he shouted. “Let go the life-buoy, Allan.”

Instinctively Allan did as he was told, and sent the big cork ring flying after Ralph, but seeing the merry twinkle in Rory’s eye, and knowing there was no necessity for it, he repented having done so next minute.

“Lower away your dinghy,” cried McBain to Allan, as he hauled the headsails to windward and stopped the cutter’s way, “it will be a bit of practice for you.”

Allan was pulling away astern two minutes after in the little boat, dignified by the undignified name of dinghy, for she was very tiny indeed, but Allan could have sculled a wash-tub.

He soon met Ralph coming ploughing and spluttering along, breasting the billows, for he was a powerful young swimmer, with the life-buoy in front of him, which, however, he scorned to make use of.

“Take your little joke on board,” he cried laughing. Allan picked up the buoy and threw Ralph a rope.

“That’s better,” said Ralph, and in a few minutes more they were alongside and on board.

Rory was singing “A life on the ocean wave,” and the merry twinkle had not left his eyes.

When Ralph had changed his dripping clothes for dry ones, and reappeared looking somewhat blue, Rory had his laugh out, and all hands were fain to join.
