"We took 'em and trained 'em—gradually, you understand. Taught 'em to salute the King's uniform, an' just why orders had to be obeyed: explained it all gently"—the stupendous hand made a gesture in the air as if stroking something. "Then after a while we moved 'em on to something else—the Game itself, in fact—and my merry men tumbled to it in no time. It was in their blood, I guess. They'd hunted something all their lives, and they weren't scared because they had to take on something a bit bigger. I tell you, after a few weeks I just prayed for a submarine to come along and show what we could do."

The Volunteer grinned understandingly. "Well?" he said.

"We got one a week later. Just for all the world like a bloomin' salmon. First we knew that there was one about was the Merrie Maggie, one of our trawlers, blowing up. Well, I'd been over the same spot in the morning, and there were no mines there then, so I knew our friend wasn't far off…." The Submarine Hunter mused for a moment, staring at his clasped hands, with the faint blue tattoo-marks showing under the tan. "We got him at dawn—off a headland…. Oh, best bit of sport that ever I had!" The speaker's hard grey eye softened at the recollection. "We've got lots since, but never one as neat as that. He just came to the surface and showed his tail-fin and——" the huge hands made a significant downward gesture.

If you have ever heard a Regimental Bombing Officer describe the clearing of an enemy traverse, you will understand the complete expressiveness of that gesture.

"I'm going North now to join a new base up there. There are one or two dodges that I can put them up to, I reckon."

The Volunteer filled and lit a pipe.

"Pretty work it sounds. Ours is duller, on the whole, but we get our share of excitement. You never sight a steamer flying neutral colours without the possibility of her hoisting the German ensign and slipping a torpedo into you. That's why we introduced the Red Pendant business. It meant inconvenience for all parties, but neutrals have only got the Hun to thank for it."

"Never heard of it," said the other. "Fritz-hunting is my game."

"Well, you see, ever since they've tried to slip raiders through the blockade we can't afford to close a stranger flying neutral colours within gun or torpedo range. So we had to explain to neutrals that a red flag hoisted by one of our merchant cruisers is the signal to heave to instantly, and that brings her up well out of range. Then we drop a boat and steam off and signal her to close the boat, and the boarding officer goes on board and examines her papers. If she's got a cargo without guarantees she's sent into one of the examination ports under an armed guard to have it overhauled properly."

"For contraband?"
