A couple of horsemen were galloping down the slope, and a few minutes later the command was passed back from the front,—

"Fall in! Examine arms and ammunition!"

The men sprang forward to the row of piled arms, and then, like an electric current, the report passed from one to another—the enemy was in sight!

"Cast loose one packet of your ammunition," said the commander of the company.

Jack's fingers twitched with excitement as he pulled off the string of the familiar little brown paper parcel, and dropped the ten cartridges into his pouch. It was the real thing now, and no mistake!

Moving forward in line of columns, the force ascended the slope, and after one more brief halt, while further reconnaissances were being made, began to advance across the level stretch beyond, from which a good view was obtained of the distant valley of Abu Klea, with the steep hills rising on either side, and opening out at the entrance of the pass.

"There they are!"

Far away, on the dark, rocky eminences, crowds of tiny, white-robed figures could be clearly distinguished moving and gesticulating in an excited manner.

Steadily the force advanced until, when within a comparatively short distance of the mouth of the valley, the word for "close order" was given. The camels were driven forward into a solid mass in rear of the leading company as it halted; the men dismounted, and knee-lashed their steeds.

There was not much time for looking about, for the order was immediately given to build a zareba; and while some men were set to work to cut down brushwood, Jack and his comrades were told off to gather stones for constructing a breastwork.
