"New destroyer, isn't she?" inquired Farrar.

"Yes; the old boat of that name piled herself on the rocks on the East Coast. We've got a topping skipper—Tressidar's his name. We're off Fritz-hunting in the Irish Sea, I hear. Not quite so exciting as the North Sea, perhaps, but I've had enough of the Auldhaig Flotilla Patrol for the present, thank you. Hullo, who's the Brass Hat?"

He indicated a tall, florid-featured Staff Officer in the uniform of a major who was striding between the press of bluejackets in the direction of the rear portion of the train. By his side walked a huge St. Bernard dog, muzzled and held by a massive steel chain.

"Hanged if I know," replied Farrar. "I didn't see him at Paddington, but that's not saying much. Suppose he's giving an eye to those Tommies in the fore-part of this packet. Fine dog, anyhow."

Orders were shouted along the platform. Rapidly the navy folk boarded the train until the major stood almost alone in the resplendent glory of his immaculate uniform.

"Guard!" he exclaimed peremptorily. "I want to accompany this brute in your compartment. He doesn't like a crowd, but he's quite safe when I'm with him."

"Very good, sir," replied the guard, touching his cap. "We're just off, sir."

"Wonder who the Brass Hat is?" reiterated Holcombe. "Did you notice that he didn't seem at all keen on salute-hunting? Kept well this end of the platform, and didn't have a pal to speak to. Well, if he is a hermit, he'll have solitude and repose in the luggage van. Dashed fine dog," he added in endorsement of his chum's declaration. "Advantage of having a Service chap for a master: no jolly worry about feeding the brute."

For some minutes silence reigned. The officers in the compartment were studiously watching the unsurpassable Devon scenery as the train swept through the coombes of the shire of the Sea Kings.

"Wonder when we'll see this sight again?" remarked Farrar. "Dash it all, I love the sea as a brother, but I'm jolly glad to get a sniff of the land after days and weeks of steady steaming. That's where you destroyer fellows score: a week or ten days is your limit."
