"Now I think they are near enough, sheik," Edgar, who had levelled his rifle at one of the horsemen, said. As he spoke he pulled the trigger, and simultaneously with the sharp crack of the piece the Arab threw up his arms and fell from his horse. The sheik and five of his men fired almost at the same moment. Kneeling as closely as they could, there was room for but seven along the face of the fort fronting the enemy, and at Edgar's suggestion the chief had divided the men into three parties, each of which after firing was to fall to the rear and reload, their places being taken by the others in succession. Thus there would always be a reserve and the fire could be kept up without interruption. Volley after volley was fired, Edgar loading quickly enough to repeat his fire with each squad.

So rapidly did the Arabs pass over the intervening ground that they reached the outside hedge of thorns just as the party who had first fired had again taken their places in front. Five of the dervishes had fallen and several were wounded, but this had not checked their speed for a moment, and under the orders of their leaders they at once fell to work with their swords and knives to destroy the hedge. The work was done far more rapidly than Edgar had thought possible, and they then fell upon the more formidable obstacle piled up against the rocks, attacking it on three sides simultaneously. The defenders now fired independently, each as fast as he could load, Edgar shouting continuously "Steady! steady! take a good aim each time," and the sheik re-echoing his words.

The Arabs, however, were too excited to obey, and the greater part of their shots were thrown away. Several of the dervishes had fallen, but the process of clearing away the hedge proceeded with alarming rapidity. The work was, however, speedily abandoned at the face where Edgar was stationed, for at each crack of his rifle a dervish fell. Leaving three of the men to defend that face the rest joined the defenders at the sides, the sheik taking the command on one side, Edgar on the other. The fire now became more steady, the sheik enforcing his orders by vigorous blows with the staff of his spear, while Edgar's rifle on his side more than made up for his want of influence with the men.

In their fury several of the dervishes sprang boldly into the midst of the thorns and strove to climb up, but they were met by the spears of the defenders, and not one gained an entrance. It was less than ten minutes after the first shot had been fired when the leader of the dervishes, seeing how fast his men were falling and that they would soon be no stronger than the defenders of the fort, called them off from the attack. As they turned and ran the defenders leapt to their feet with yells of triumph; but the dervishes, turning round, fired several shots. The sheik received a ball in his shoulder and two of his companions fell dead. The others at once took to their shelter again, and kept up their fire until long after the last of the dervishes was out of range. The moment the retreat began Edgar looked out for his man, of whom he had not hitherto caught a glimpse in the heat of the conflict. He soon caught sight of him, and taking a steady and careful aim with his rifle on a stone, fired, and Hamish fell headlong forward, the ball having struck him fair between the shoulders.

A yell of triumph rose from the Arabs. The traitor who had brought the Mahdists down upon them was punished; the one man who could guide the foe to the wady was killed. As soon as the enemy got out of reach of shot they gathered in consultation. The defenders could see that the discussion was excited and violent; they waved their arms, stamped, and seemed on the point of coming to blows with each other. While they were so engaged the garrison looked out at the field of battle round the fort. No less than fifteen of the assailants had been killed, while of the defenders but two, the one an old man and the other a boy, had fallen. The sheik begged Edgar to bandage his shoulder; he seemed to feel the pain but little, so delighted was he with the issue of the contest. Edgar soaked a pad of the cotton cloth and laid it on the wound, and then with long strips of the same material bandaged the arm tightly to the side, and with other strips fastened as well as he could the pad in its place.

"They are scattering over the sand-hills," one of the Arabs said just as he had finished, and in a short time a dropping fire was opened at the fort.

The Arabs would have replied, but the sheik said that it was a waste of powder, for their guns would not carry as far as the rifles in the hands of the dervishes, and it was better that they should lie quiet behind their shelter and allow the enemy to throw away their fire.

"What will they do next, do you think, sheik?"

"I do not think they will make another attack, Muley; at any rate not in the daytime. They must know they are not greatly superior to us in force, being now but twenty-five to our eighteen, and no doubt many of them are wounded. They may try to besiege us. They will know that we have a supply of water—we should never have shut ourselves up here without it—but that will fail in time."

"But their own supply will fail," Edgar said. "Probably they have only brought enough with them for what they supposed would be a two days' march to the wady."
