"Belize, La Guaira, Barbadoes," said Grandfather Nat, musingly. "It's the rough reason thereabout, an' it's odds she may be blown out of her course. But the mail——"

He stopped and turned his head. There was a sudden stamp of feet outside the door behind us, a low and quick voice, a heavy thud against the door, and then a cry—a dreadful cry, that began like a stifled scream and ended with a gurgle.

Grandfather Nat reached the door at a bound, and as he flung it wide a man came with it and sank heavily at his feet, head and one shoulder over the threshold, and an arm flung out stiffly, so that the old man stumbled across it as he dashed at a dark shadow without.

I was hard at my grandfather's heels, and in a flash of time I saw that another man was rising from over the one on the doorsill. But for the stumble Grandfather Nat would have had him. In that moment's check the fellow spun round and dashed off, striking one of the great posts with his shoulder, and nearly going down with the shock.

All was dark without, and what I saw was merely confused by the light from the bar-parlour. My grandfather raised a shout and rushed in the wake of the fugitive, toward the stairs, and I, too startled and too excited to be frightened yet, skipped over the stiff arm to follow him. At the first step I trod on some object which I took to be my grandfather's tobacco-pouch, snatched it up, and stuffed it in my jacket pocket as I ran. Several men from the bar were running in the passage, and down the stairs I could hear Captain Nat hallooing across the river.

"Ahoy!" came a voice in reply. "What's up?" And I could see the fire of a purl-boat coming in.

"Stop him, Bill!" my grandfather shouted. "Stop him! Stabbed a man! He's got my boat, and there's no sculls in this damned thing! Gone round them barges!"

And now I could distinguish my grandfather in a boat, paddling desperately with a stretcher, his face and his shirt-sleeves touched with the light from the purl-man's fire.

The purl-boat swung round and shot off, and presently other boats came pulling by, with shouts and questions. Then I saw Grandfather Nat, a black form merely, climbing on a barge and running and skipping along the tier, from one barge to another, calling and directing, till I could see him no more. There were many men on the stairs by this time, and others came running and jostling; so I made my way back to the bar-parlour door.

It was no easy thing to get in here, for a crowd was gathering. But a man from the bar who recognised me made a way, and as soon as I had pushed through the crowd of men's legs I saw that the injured man was lying on the floor, tended by the potman; while Mr. Cripps, his face pallid under the dirt, and his nose a deadly lavender, stood by, with his mouth open and his hands dangling aimlessly.
