Jack hesitated, but there was no sign yet of the long lane turning.

"It's very good of you, sir," he answered, "but I'd rather they didn't know my whereabouts. If I live through this, and return to England, I shall still be a private soldier. I'm much obliged to you, sir, all the same."

He saluted again, and walked away. Valentine looked after the retreating figure with a queer, sad smile upon his face.

"You're a difficult fish to deal with," he muttered; "but we shall land you again some day, though I hardly know how."

Late in the afternoon the column was once more in motion, and then commenced an experience which Jack, and all those who shared in it, have probably never forgotten. At first the march was orderly, but, as the hours went by, progress became more and more difficult. Camels, half-starved and exhausted, lagged and fell, causing continual delay and confusion. The desert track having been abandoned in order to avoid possible collision with the enemy, the road lay at one time through a jungle of mimosa trees and bushes, when the disorder was increased tenfold—baggagers slipped their loads, and ranks opening out to avoid obstacles found it impossible in the dark to regain their original formation. Utterly unable to keep awake, men fell asleep as they rode, drifting out of their places, some, indeed, straying off into the darkness, never to be seen again.

Worn out, and chilled to the bone with the bitter night air, Jack clung to his saddle, dozing and waking; dreaming for an instant that Queen Mab was speaking to him, and rousing with a start as the word was passed, "Halt in front!" to allow time for the rear-guard closing up with the stragglers. At each of these pauses poor "Lamentations" knelt of his own accord; and his rider, dropping down on the sand by his side, fell into a deep sleep, to be awakened by the complaining grunts of the camels as the word, "All right in rear!" gave the signal for a fresh start.

After each stoppage it was no easy matter to get the weary animals on their legs again; and almost equally difficult in many instances to rouse their riders from the heavy slumber into which they fell the moment they stretched themselves upon the ground.

"Pass the word on, 'All right in rear!'"

"Oh, dear! I'd give a month's pay for an hour's sleep," mumbled Joe Crouch.

"Get up, you fool!" answered Jack, kicking the recumbent figure of his comrade. "D'you want to be left behind?"
