The three chieftains still lingered upon the knoll, looking down with hungry eyes and compressed lips at the dark steel-tipped patch.  “They are slower to start than the men of Egypt,” the Sheik of the Hadendowas growled in his beard.

“Slower also to go back, perchance, my brother,” murmured the dervish.

“And yet they are not many—­3,000 at the most.”

“And we 10,000, with the Prophet’s grip upon our spear-hafts and his words upon our banner.  See to their chieftain, how he rides upon the right and looks up at us with the glass that sees from afar!  It may be that he sees this also.”  The Arab shook his sword at the small clump of horsemen who had spurred out from the square.

“Lo! he beckons,” cried the dervish; “and see those others at the corner, how they bend and heave.  Ha! by the Prophet, I had thought it.”  As he spoke, a little woolly puff of smoke spurted up at the corner of the square, and a 7 lb. shell burst with a hard metallic smack just over their heads.  The splinters knocked chips from the red rocks around them.

“Bismillah!” cried the Hadendowa; “if the gun can carry thus far, then ours can answer to it.  Ride to the left, Moussa, and tell Ben Ali to cut the skin from the Egyptians if they cannot hit yonder mark.  And you, Hamid, to the right, and see that 3,000 men lie close in the wady that we have chosen.  Let the others beat the drum and show the banner of the Prophet, for by the black stone their spears will have drunk deep ere they look upon the stars again.”

A long, straggling, boulder-strewn plateau lay on the summit of the red hills, sloping very precipitously to the plain, save at one point, where a winding gully curved downwards, its mouth choked with sand-mounds and olive-hued scrub.  Along the edge of this position lay the Arab host—­a motley crew of shock-headed desert clansmen, fierce predatory slave dealers of the interior, and wild dervishes from the Upper Nile, all blent together by their common fearlessness and fanaticism.  Two races were there, as wide as the poles apart—­the thin-lipped, straight-haired Arab and the thick-lipped, curly negro—­yet the faith of Islam had bound them closer than a blood tie.  Squatting among the rocks, or lying thickly in the shadow, they peered out at the slow-moving square beneath them, while women with water-skins and bags of dhoora fluttered from group to group, calling out to each other those fighting texts from the Koran which in the hour of battle are maddening as wine to the true believer.  A score of banners waved over the ragged, valiant crew, and among them, upon desert horses and white Bishareen camels, were the Emirs and Sheiks who were to lead them against the infidels.
