Edgar did so, and in a few seconds was again ready to fire.

"Inshallah!" the sheik exclaimed, "but it is wonderful. No wonder that they tell me that the roar of the guns was like never-ceasing thunder, and that the sound of one shot could not be heard from another. Can you take out the cartridge without firing?"

Edgar showed him how this was done, and the sheik then repeatedly loaded and unloaded the gun until he could manipulate it quickly. "And what is this thing?" he asked, touching the back sight.

Edgar explained to him that the sight was raised or lowered according to the distance of the object to be aimed at.

"The Franks are wonderful men," the sheik said gravely; "if they had but the true faith, and Allah was with them, no one could stand against them. When the ammunition is used up can you make more?"

Edgar shook his head.

"If I had caps to fit in here and a mould for the bullets I could refill these cases two or three times, but after that they would be useless.

Powerful machinery is used for making these cases. It might be possible to have them made by hand by a skilled worker in bra.s.s in Khartoum, but it would be very expensive, and I am afraid, sheik, when the ammunition is gone the gun would be useless unless you can procure some more cartridges from traders in Egypt; unless, indeed, my countrymen have retaken Khartoum, in which case I could obtain for you any quant.i.ty of cartridges."

"Your countrymen have retired to Korti," the sheik said.

Edgar gave a cry of disappointment. He had feared that when the news of Gordon's death was known the expedition might be abandoned; but he had still retained some hope that it might advance to Khartoum. The news that they had already fallen back to Korti came as a shock.

"How did you learn the news, sheik?" he asked presently. "You did not say that you had spoken to anyone."

"Yes, we went a little way into the fields in hopes of catching sight of Hamish, and came upon two peasants who were gathering the crop. They had seen nothing of the negro. Upon questioning them as to what was going on at Khartoum they said that the Mahdi was still all-powerful; that the Kaffirs had fallen back from Metemmeh and were scattered along the river between Korti and Dongola; and that the Mahdi had announced that his forces would ere long advance, conquer Egypt, and destroy the Kaffirs."

"Do you mean to wait for the attack of the Mahdi's men here or to go to meet them?" Edgar asked after a long pause.

"If they come here too numerous to fight we must fly; but if they are not too strong we will give them battle here. Why should we go to meet them?"

"It is for you to decide," Edgar said. "I know nothing of your Arab ways of fighting. But it seemed to me that it might be better, if they are not altogether too strong, to meet them as near the other wells as we can."

"But why so, Muley? They would have water close to them and we should have none. If one was wounded he would have to be carried a long distance. Why do you advise that we should fight them there?"

"You told me, sheik, that the existence of this well was only known to you and your people and a small section of the tribe."

"That is so, Muley. It is a secret that has been well guarded. The wady has served as a retreat many times in our history."

"If they come on and any of them go back again the secret will be a secret no longer," Edgar said. "It is for this reason that I thought that we had better go out and meet them. There is but one man with them who knows the way hither, and against him our b.a.l.l.s should be all directed. If we kill him they would be without a guide and would be unable to find the way, for they would never venture into this desert knowing that if they failed to find our well they might all perish for want of water."

"You speak well," the sheik said. "I had not thought of this; but I see that your plan is a good one. As soon as I learn that they have arrived at the wells we will set out to meet them unless their force is altogether too strong for us."

On the seventh day after their arrival at the wady the messenger who had been despatched for aid returned. His news was that the greater part of the men were away; they were expected in a few days, but it might be a week or more before they came back. The sheik was unwilling to send off the few men at the douar, but promised that as soon as his main force returned he would set out with the whole strength of his fighting men to their a.s.sistance.

Upon the following morning one of the men left to watch the wells also returned. He had come through without stopping, and reported that late in the evening before he left he and his companions had seen a line of camels with some hors.e.m.e.n coming towards the wells. He had waited until morning in order to discover their force; he put it down as forty men.

"That is very bad news," the sheik said. "We can only muster eighteen fighting men, and some of these are old and others mere lads. They are two to one against us, and if we were beaten and forced to fly their hors.e.m.e.n would overtake us and destroy us. Think it over, Muley; you are full of expedients."

"How many men do you expect to get from the other douar?"

"Their encampment is the same size as ours; they are sure to leave some of the old men to guard it, perhaps fifteen will come. That will make our force nearly equal to theirs, and we might defend this wady, though I doubt it, but I am sure that they would beat us easily in the desert.

They are almost all armed with the rifles that they took at El-Obeid from Hicks Pasha's men, and will have found an abundance of arms at Khartoum; besides, these dervishes fight desperately. The faith they have in the Mahdi gives them strength and courage; they do not care whether they die or live, and doubtless picked men have been sent on the expedition. I fear there is nought before us but flight, unless you with your knowledge of the Frank method of war can hit upon some plan."

"I will think it over, sheik, but at present I see no way in which we can withstand them. We might, of course, cut down trees and make so strong a fort here that we might beat them off; but in that case they might return in much greater numbers, therefore it seems to me that if we fight we must fight at the other wady."

"Then we cannot fight at all," the sheik said decisively. "There are two to one against us, and it would be madness to attack them when they could with their hors.e.m.e.n cut off all retreat."

"I will think, sheik," Edgar said, rising and walking away.

In half an hour he returned. "I have thought of a plan, sheik, but it is not without great danger."

"I care not for danger," the sheik said, "so that it be but possible."

"My idea is this: that we should load up all your camels with closely-pressed bundles of forage; then that we should advance a day's march across the desert; and there that we should form a zareba. With the forage we should, of course, take water-skins with us, with sufficient to last for at least a week. I should send the camels back again as soon as they are unloaded, and should order those who remained behind to load all their goods upon them and to set out either for the other douar of your tribe or for the villages to the south. I should send a messenger to the other douar to say that we are going to defend the zareba to the last and praying them to come at once to our rescue, promising the moment they appear to sally out and fall upon the dervishes while they attack them in rear. Your messenger should point out that before they arrive a number of the enemy will certainly have fallen in their attack upon us, and we shall, therefore, be decidedly superior to them in point of numbers."

"The plan is a bold one," the sheik said; "but do you think that it would be possible for us to defend the zareba?"

"I think so, sheik. It need be but a small one some twelve feet square inside. They will have to cross the open to attack us, and outside we can protect it by a facing of p.r.i.c.kly shrubs."

"We will do it!" the sheik said in a tone of determination, springing to his feet. "One can but die once, and if we succeed it will be a tale for the women of our tribe to tell for all time."

CHAPTER XVIII.

THE ZAREBA.

No sooner had the sheik decided to carry out Edgar's plan than he rapidly issued his orders. In five minutes the whole of the inhabitants of the douar were at work, the boys going out to fetch the camels, the men cutting down the long gra.s.s near the well and laying it in great bundles very tightly pressed together, the women cooking a large supply of flat cakes for the party. In two hours the preparations were completed and the twenty men moved off from the oasis. They travelled until ten o'clock in the evening. By the light of the moon, which was four days short of full, the sheik and Edgar selected a point for the erection of the zareba. It was a patch of rock cropping up from the summit of a sand-hill that fell away from it on all sides, and was just about the size required for the zareba. The camels were unloaded and the bundles of forage laid down side by side and formed into a square, the wall being some four feet thick and two feet high. The whole party, including the boys who were to take back the camels, then set to work to cut th.o.r.n.y bushes. These were piled thickly at the foot of the rock all round, being kept in their places by stakes driven into the sand and by ropes interlacing them. The work was only completed just as daylight broke.

"I don't think," Edgar said, walking round the little fort, "that any men can get through this hedge of thorns until they have pulled it away piece by piece, and that, with us lying in shelter above and firing down upon them, will be a difficult task indeed."

The Arabs, who had obeyed the chief's orders with reluctance and had been very silent upon the journey out, were now jubilant, feeling convinced that they could beat off the attack of such a force as that which they heard was advancing. The camels were now sent off, and they had scarcely disappeared among the sand-hills when an Arab was seen approaching on a camel.

"It is our scout," the sheik said; "he brings us news."

He tied a cloth to the end of a spear and waved it. A minute later the camel's course was changed and the rider soon arrived outside the fort.

"What is your news, Yussuf?"

"They are going to start this morning," the man said. "I crept in as soon as it became dark last night and made my way close up to them, and I gathered that they have decided to march this morning on to Wady El Bahr Nile. They could not stay where they were any longer as they had only brought with them sufficient food for the camels for the march to the wady, where they made sure they should find an abundant supply, and having given them a day's rest they were going to push forwards at once to the next wady, where they made certain of finding the fugitives."

"Will they be here to-night?" Edgar asked the sheik.

"I should think not, Muley. The regular halting-place is five miles away, and as that is about half-way they will probably stop there and start perhaps an hour before daybreak."

The scout was sent off to the wady with the news, and the little garrison spent the day in strengthening their fort, making another hedge of bushes three or four yards beyond the other, and gathering a large number of the heaviest stones they could find. These were laid on the gra.s.s rampart, which was thus raised in height nearly a foot, openings being left in the stones through which the defenders could thrust their guns and fire without exposing their heads to the shots of the a.s.sailants. This still further added to the confidence of the Arabs, and when all was completed they indulged in defiant gestures and wild yells signifying contempt, in the direction from which the enemy would probably advance.

At nightfall two of the men were posted as sentries, as it was possible the Mahdists might push straight forward. There was, however, no alarm during the night; but just as day broke the sentries reported that there were hors.e.m.e.n to be seen in the distance. As there was no object in concealment all leapt to their feet. Nine hors.e.m.e.n were seen on the brow of a sand-hill some two miles away. They were presently lost sight of as they descended into a dip, and a minute or two later the line of camels was seen following in their steps. The spear with the cloth was elevated as a flag; and when the hors.e.m.e.n appeared on the next sand-hill, it was evident by the suddenness with which they pulled up their horses that they saw it.

Half a minute later they started again, this time at a canter. When they came within half a mile the sheik asked, "Why do you not fire, Muley; your gun will carry that distance easily?"
