“There they go!” cried Bracy excitedly, as the active lads selected as scouts began to ascend the track in the lightest order; and their progress was watched with the keenest anxiety as they rose more and more into the full view of the regiment, apparently meeting with no obstacles to their progress, and showing the track to be followed by the waiting party below.

Just then the Colonel rode back to where the young officers were standing.

“This track is so narrow, Roberts,” he said, “that your company will be ample to protect the rear; so I shall trust entirely to you. If we are to be attacked it will be in front; of that I am convinced, though probably the attacking will be on our part, for sooner or later we shall find a rough hill-fort, strongly held.”

“Hope we shan’t fall into some trap, sir,” said Roberts earnestly.

“I hope not,” said the Colonel, turning his horse and moving forward, but only to turn his head again.

“It will be stiff work for the train,” he said; “but they must do it. You will help to keep the baggage-men well up to their work, for I mean to get through this pass to-night.”

“Nice job,” said Roberts bitterly. “We shall have the enemy behind us, stirring us up, and we shan’t be able to get on without pricking up the mules and camels.”

“No firing yet,” said Bracy, without heeding the foreboding remarks of his companion. “They’re getting well on. Ah! there goes the advance.”

For a bugle rang out, its notes being repeated again and again with wondrous clearness from the faces of the black-looking barren rocks on high, and the scene became an animated picture to the men of the rear-guard, who lay on their arms, resting, while the regiment filed up the track, two abreast, giving life to the gloomy gorge, which grew and grew till the baggage animals added their quota to the scene.

“At last!” cried Roberts, as their own turn came, and after a long and careful search backward from a point of vantage with his glass, he gave the word, and his rested lads began to mount eagerly, but with every one keeping an eye aloft for the blocks of stone they expected to come crashing down, but which never came any more than did the sharp echoing rifle-fire announcing the attack upon some rough breastwork across the shelf.
