Cassidy saluted and backed out of the cabin to confer with his equally anxious mates on the next course to adopt. The men were grievously concerned about Flirt's disappearance. Never before had the mascot been "absent without leave ".

Some of the crew went on deck and began a pantomime conversation with a Russian seaman on sentry duty on the quay side. By dint of signs and the promise of a "plug o' ship's 'bacca", the Muscovite was made to understand that R19's mascot was missing, and that her recovery would result in a substantial reward.

All that evening there was a constant stream of Russian bluejackets and marines, bringing with them curs of all sizes and descriptions, until the harassed officer of the watch was reduced to the borders of unparliamentary language, while the crew were partly solaced by the sight of the impromptu dog show.

Morning came, but with it no signs of Flirt. A sympathetic Russian petty officer, who could speak English, volunteered to make enquiries at all the landing-places, although he expressed his opinion that the dog must be roaming about somewhere on the island.

With the resumption of work Flirt's disappearance was temporarily forgotten. The Hon. Derek and Mr. Macquare were anxiously dividing their attention between the progress of the repairs and the steady formation of the ice. Already the water alongside was covered with two inches of clear ice, while, in order to enable the divers to labour at their task of refixing the hydroplane, men had to be told off to keep the floes away from the submarine's bows.

Suddenly Cassidy, who was engaged in red-leading the newly-fixed periscopes, gave a shout of surprise.

"Sw'elp me!" he exclaimed, pointing at a small brown object showing clearly on the glistening field of ice. "There's Mr. Fordyce's dawg."

The animal had made her way across the expanse of frozen water until she gained the edge of the still-open channel, on which slabs of ice of varying sizes and thickness were drifting.

Informed of Flirt's return by the A.B.'s shout, the Lieutenant-Commander whipped out his binoculars.

"By Jove," he exclaimed, "the little beast's about to swim for it! She'll be done in, Macquare."
