"That sounds nice," I commented, at which he began again.

"Aye an' it's vera dirty watter. It's the last in the bag, an' there's tadpoles an' wee crocodiles swimmin' in't, an——"

"Hold hard, Stewart," said Phil, while Mac was groping about for something substantial to throw at his comrade's head. "Hold hard, you grinning gorilla, and let us discover the mysterious ingredients of our humble fare for ourselves."

Mac volunteered for the first spell of duty, and as a preliminary he carefully drew the small shot charges from his cherished elephant-gun, and replaced them with ominous-looking buckshot cartridges.
