"The Vincenty," grumbled Teddy Butson; "and by shot to me if I even know what it's like."

"Like!" McInnes' jaws shut on the word like a steel trap. "The scarp's thirty feet high, and the ditch accordin'. The last on the west side it will be—over by the river. I know it like your face, and its uglier, if that's possible."

"Dick Webster was saying it's mined," put in Nat, commanding a firm voice.

"Eh? The glacis? I shouldn't wonder. Walker will know."

"But what'll he do?"

"Well, now"—Dave seemed to be considering—"it will not be for the likes of me to be telling the brigadier-general. But if Walker comes to me and says, 'Dave, there's a mine hereabouts. What will I be doing?' it's like enough I shall say: 'Your honour knows best; but the usual course is to walk round it.'"

Teddy Butson chuckled, and rubbed the back of his axe approvingly. Nat held his tongue for a minute almost, and then broke out irritably: "To hell with this waiting!"

His nerves were raw. Two minutes later a man on his right kicked awkwardly against his foot. It startled him, and he cursed furiously.

"Hold hard, Spuds, my boy," said the man cheerfully; "you ain't Lord
Wellington, nor his next-of-kin, to be makin' all the noise."

Teddy Butson wagged his head solemnly at a light which showed foggily for a moment on the distant ramparts.
