“Cover, cover, Mr Bracy,” cried the Colonel sharply, and as he reined up he was put quickly in possession of the facts.

“Shall we have to go back, Sergeant?” whispered Gedge.

“You will—under arrest, sir, if you don’t keep that tongue between your teeth.”

“All right, Sergeant,” muttered Gedge. “I only wanted to know.”

He knew directly after, for the Colonel cried sharply:

“That’s right, my lads; keep close, and fire the moment you see a movement. You six men go over the side there, and fire from the edge of the road.”

The section spoken to rose and changed their positions rapidly, and as they did so a couple more blocks of stone were set in motion from above, and struck as the others had done, but did not break, glancing off, and passing over the men’s heads with a fierce whir.

“Cover the advance with your company, and change places with the rear-guard when they have passed. Steady, there, my lads,” continued the Colonel to the next company of the halted regiment; “forward!”

He took his place at their head, and advanced at a walk as coolly as if on parade; and the first movement seemed like a signal for stone after stone to be sent bounding down, and to be passed on their way by the long, thin, bolt-like bullets from the covering company’s rifles, which spattered on the rocks above and kept the enemy from showing themselves, till, finding that every stone touched in the same place and glanced off the projecting shoulder half-way up, they became more bold, irritated without doubt by seeing the soldiers continue their course steadily along the track in spite of their efforts to stop their progress.

“That’s got him,” cried Bracy excitedly as he watched a man, who at the great height looked a mere dwarf, step into full view, carrying a block upon his shoulder.
