"The idea is excellent, Nessus."

The reservoirs of Carthage were of enormous extent, and some of these remain to this day and are the wonder and admiration of travellers. They were subterranean, and were cut from the solid rock, the stone extracted from them being used for the walls of the buildings of the city. Pillars were left at intervals to support the roof, and it was calculated that these underground lakes--for they were no less--contained sufficient water to supply the wants of the great city for at least six months.

These vast storing places for water were an absolute necessity in a climate like that of Northern Africa, where the rain falls but seldom.

Without them, indeed, Carthage would have been at the mercy of the first army which laid siege to it.

The greatest pains were devoted to the maintenance of the water supply.

The rainfall from the roofs of the temples and houses was conducted to the reservoirs, and these stores were never drawn upon on ordinary occasions, the town being supplied with water brought by aqueducts from long distances among the hills. Here and there openings were cut in the rock which formed the roof of the reservoirs, for the admission of air, and at a few points steps from the surface led down to the water. Iron gates guarded the entrance to these.

Nessus and his friends had the evening before unfastened one of these gates. The lock was old and little used, as the gate was placed rather to prevent children and others going down to the water than for any other purpose, and the Arabs had found little difficulty in picking the rough lock.

Malchus followed Nessus down the steps until he reached the edge of the water, some fifty feet below the surface. Here stood two Arabs bearing torches. At the foot of the steps floated the raft, formed, as Nessus had said, of four inflated sheepskins connected by a framework of planks. Across these a bullock's hide had been stretched, forming a platform. On this were some rugs, a skin of wine, and a pile of flat cakes and fruit, together with half a dozen torches.

"Thanks, my friends!" Malchus said to the Arabs. "Some day I may be able to prove that I am grateful to you."

"The friends of Nessus are our friends," one of the Arabs replied simply; "his lord is our master."

"Here is a paddle, my lord," Nessus said. "I propose that you should paddle straight away as far as you can see a torch burning here; then that you should fasten the raft to a pillar. Every other night I will come with provisions here and show a light. If you see the light burn steadily it is safe for you to approach, and I come only to bring food or news; if you see the torch wave to and fro, it is a warning that they intend to search the reservoirs. I do not think it likely they will do so; still it is best to be prepared, and in that case you must paddle far away in the recesses. They might search for a long time before they find you. I trust that your imprisonment here will not be long, but that we may hit upon some plan of getting you out of the citadel. I would gladly go with you to share your solitude, but I must remain outside to plan some way of escape."

With a short farewell to his faithful follower Malchus took his place on the raft, having lit a torch and fastened it upright upon it. Then he paddled slowly away, keeping between the lines of heavy columns. His rate of progress was slow, and for half an hour he kept the torch in sight. By this time he felt sure that he must be approaching the boundary of the reservoir. He therefore moored his raft against a pillar and waved his torch backwards and forwards. The signal was answered by a similar movement of the distant light, which then disappeared. Malchus now extinguished his own torch, placed the means of relighting it with which Nessus had furnished him close to his hand, and then, wrapping himself in a rug, lay down to sleep.

When he awoke it was day. The light was streaming down on to the water from an opening two or three hundred yards away, while far in the distance he could see a faint light which marked the place of the steps at which he had embarked. In the neighbourhood of the opening the columns stood up clear and gray against the dark background. A little further off their outlines were dim and misty; and wherever else he looked an inky darkness met his eye, save one or two faint bands of misty light, which marked the position of distant openings.

The stillness which reigned in this vast cavern was almost oppressive.

Sometimes a faint rustling whisper, the echo of some sound in the citadel above, pa.s.sed among the columns; and the plaintive squeak of a bat was heard now and then, for numbers of these creatures were flitting noiselessly in the darkness, their forms visible for an instant as they pa.s.sed and repa.s.sed between Malchus and the light. He wondered vaguely what they could find to eat here, and then remembered that he had heard that at nightfall numbers of bats could be seen flying up from the openings to the reservoirs to seek food without, returning to their hiding places when morning approached.

Malchus amused himself by thinking over the fury and astonishment of Hanno and his colleagues on hearing that their prisoner had disappeared, and he pictured to himself the hot search which was no doubt going on throughout the citadel. He thought it improbable in the extreme that any search would be made in the reservoir. Nessus would refasten the gate after pa.s.sing through it again, and the idea that he could be floating on the subterranean lake could hardly occur to them.

Then he turned over in his mind the various devices by which it might be possible to get beyond the walls of the citadel. The anxiety of Hanno and those acting with him to prevent the manner in which they had kidnapped and sentenced to death the messenger and kinsman of Hannibal from becoming known in the city, would be so great that extraordinary vigilance would be used to prevent any from leaving the citadel. The guards on the walls would be greatly increased; none would be allowed to pa.s.s the gate without the most rigourous examination; while every nook and corner of the citadel, the temples, the barracks, storehouses, and stables, would be searched again and again. Even should a search be made in the reservoir, Malchus had little fear of discovery; for even should a boat come towards the spot where he was lying, he would only have to pa.s.s the raft round to the opposite side of the great pillar, some twelve feet square, against which he was lying.

When the light faded out he again lay down to sleep. As before, he slept soundly; for, however great the heat above, the air in the subterranean chambers was always fresh and cool, and he could well bear the rugs which Nessus had provided. The next day pa.s.sed more slowly, for he had less to think about. After the daylight had again faded he began to look forward expectantly for the signal, although he knew that many hours must still elapse before Nessus would be able to make his way to the place of meeting.

So slowly did the hours pa.s.s, indeed, that he began at last to fear that something must have happened--perhaps that Nessus had been in some way recognized, and was now in the dungeons below the temple of Moloch.

At last, however, to his joy Malchus saw the distant light; it burned steadily, and he at once set out to paddle towards it. He did not light his torch--it would have taken time, and he knew that, quietly as he paddled, the sound would be borne along the surface of the water to Nessus. At last he arrived at the steps. Nessus was there alone; beside him was a basket of fresh provisions.

"Well, Nessus, what news?"

"All is well, my lord; but Hanno is moving heaven and earth to find you. The gates of the citadel were kept closed all day yesterday; and although today they have again been opened, the examination of those who pa.s.s out is so strict that no disguise would avail to deceive the scrutiny of the searchers. One or other of the men who attended you in the prison is always at the gate. The barracks have been searched from end to end, the troops occupying them being all turned out while the agents of the law searched them from top to bottom. The same has been done with the stables; and it is well that we did not attempt to hide you above ground, for a.s.suredly if we had done so they would have found you, however cunningly we had stowed you away. Of course the name of the prisoner who has escaped is known to none, but the report that an important prisoner had escaped from the state prisons beneath the temple has created quite an excitement in the city, for it is said that such an event never took place before. At present I can hit on no plan whatever for getting you free."

"Then I must be content to wait for a while, Nessus. After a time their vigilance is sure to relax, as they will think that I must have got beyond the walls."

"Are there any to whom you would wish me to bear news that you are here?"

This was a question which Malchus had debated with himself over and over again. It appeared to him, however, that Hanno's power was so great that it would be dangerous for anyone to come forward and accuse him.

No doubt every one of the leading men of the Barcine party was strictly watched; and did Hanno suspect that any of them were in communication with the escaped prisoner, he would take instant steps against them. He thought it better, therefore, that none should be acquainted with the secret until he was free. He therefore replied in the negative to the question of Nessus.

"I must wait till I am free. Any action now might bring down the vengeance of Hanno upon others. He would find no difficulty in inventing some excuse for dealing a blow at them. You think there is no possibility of escape at present?"

"I can think on no plan, my lord. So strict is the search that when the elephants went down today to the fountains for water every howdah was examined to see that no one was hidden within it."

"It will be necessary also, Nessus, if you do hit upon some plan for getting me out, to arrange a hiding place in the city."

"That will be easy enough," Nessus replied. "My friends have many relations in the Arab quarter, and once free, you might be concealed there for any time. And now I will wait no longer, for last night visits were made in all the barracks and stables by the agents of the law, to see that every man was asleep in his place. Therefore I will return without delay. In two days I will be here again; but should anything occur which it is needful to tell you I will be here tomorrow night."

Malchus watched for the light on the following evening with but faint hope of seeing it, but at about the same hour as before he saw it suddenly appear again. Wondering what had brought Nessus before his time, he paddled to the stairs.

"Well, Nessus, what is your news?"

"We have hit upon a plan of escape, my lord. As I told you my friend and I are in the stable with the elephants, our duties being to carry in the forage for the great beasts, and to keep the stables in order. We have taken one of the Indian mahouts into our confidence, and he has promised his aid; the elephant of which he is in charge is a docile beast, and his driver has taught him many tricks. At his signal he will put up his trunk and scream and rush here and there as if in the state which is called must, when they are dangerous of approach. The mahout, who is a crafty fellow, taught him to act thus, because when in such a state of temper the elephants cannot be worked with the others, but remain in the stables, and their drivers have an easy time of it.

"On the promise of a handsome reward the mahout has agreed that tomorrow morning, before the elephants are taken out, you shall be concealed in the bottom of the howdah. He will manage that the elephant is the first in the procession. When we get out into the courtyard he will slyly p.r.i.c.k the beast, and give him the signal to simulate rage; he will then so direct him that, after charging several times about the court, he shall make a rush at the gate. You may be sure that the guards there will step aside quickly enough, for a furious elephant is not a creature to be hindered.

"When he is once down to the foot of the hill the driver will direct him to some quiet spot. That he will find easily enough, for at his approach there will be a general stampede. When he reaches some place where no one is in sight he will halt the elephant and you will at once drop off him. I shall be near at hand and will join you. The elephant will continue his course for some little distance, and the mahout, feigning to have at last recovered control over him, will direct him back to the citadel."

"The idea is a capital one," Malchus said, "and if carried out will surely succeed. You and I have often seen during our campaigns elephants in this state, and know how every one flies as they come along screaming loudly, with their trunks high, and their great ears out on each side of their heads. At any rate it is worth trying, Nessus, and if by any chance we should fail in getting through the gate, the mahout would, of course, take his elephant back to the stable, and I might slip out there and conceal myself till night, and then make my way back here again."

"That's what we have arranged," Nessus said. "And now, my lord, I will leave you and go back to the stables, in case they should search them again tonight. If you will push off and lie a short distance away from the steps I will be here again half an hour before daybreak. I will bring you a garb like my own, and will take you direct to the stable where the animal is kept. There will be no one there save the mahout and my two friends, so that it will be easy for us to cover you in the howdah before the elephants go out. There is little chance of anyone coming into the stables before that, for they have been searched so frequently during the last two days that Hanno's agents must by this time be convinced that wherever you are hidden you are not there.

Indeed, today the search has greatly relaxed, although the vigilance at the gate and on the walls is as great as ever; so I think that they despair of finding you, and believe that you must either have made your escape already, or that if not you will sooner or later issue from your hiding place and fall into their hands."

Malchus slept little that night, and rejoiced when he again saw Nessus descending the steps. A few strokes of his paddle sent the raft alongside. Nessus fastened a cord to it to prevent it from drifting away.

"We may need it again," he said briefly. Malchus placed his own clothes upon it and threw over his shoulders the bernous which Nessus had brought. He then mounted the steps with him, the gate was closed and the bolt shot, and they then made their way across to the stables. It was still perfectly dark, though a very faint light, low in the eastern sky, showed that ere long the day would break.

Five minutes' walking and they arrived at the stables of the elephants.

These, like those of the horses and the oxen which drew the c.u.mbrous war machines, were formed in the vast thickness of the walls, and were what are known in modern times as casemates. As Nessus had said, the Indian mahout and the other two Arabs were the only human occupants of the casemate. The elephant at once showed that he perceived the newcomer to be a stranger by an uneasy movement, but the mahout quieted him.

While they were waiting for morning, Nessus described, more fully than he had hitherto had an opportunity of doing, the attack made upon him on board the ship.

"I was," he said, "as my lord knows, uneasy when I found that they had recognized you, and when we were within a day's sail of Carthage I resolved to keep a lookout--therefore, although I wrapped myself in my cloak and lay down, I did not go to sleep. After a while I thought I heard the sound of oars, and, standing up, went to the bulwark to listen. Suddenly some of the sailors, who must have been watching me, sprang upon me from behind, a cloak was thrown over my head, a rope was twisted round my arms, and in a moment I was lifted and flung overboard.

"I did not cry out, because I had already made up my mind that it was better not to arouse you from sleep whatever happened, as, had you run out, you might have been killed, and I thought it likely that their object would be, if you offered no resistance, to take you a prisoner, in which case I trusted that I might later on hope to free you. As my lord knows, I am a good swimmer. I let myself sink, and when well below the surface soon got rid of the rope which bound me, and which was, indeed, but hastily twisted round my arms. I came up to the surface as noiselessly as possible, and after taking a long breath dived and swam under water as far as I could. When I came up the ship was so far away that there was little fear of their seeing me; however, I dived again and again until in perfect safety.

"I heard a boat rowed by many oars approach the vessel. I listened for a time and found that all was quiet, and then laid myself out for the long swim to sh.o.r.e, which I reached without difficulty. All day I kept my eye on the vessel, which remained at anchor. As I could not tell to which landing place you might be brought I went up in the evening and took my post on the road leading up here, and when towards morning a party entered, carrying one with them on a stretcher, I had little doubt that it was you.

"I was sure to find friends among the Arabs either belonging to the regiment stationed in Byrsa or those employed in the storehouses or stables; so the next morning I entered the citadel and soon met these men, who belonged to my tribe and village. After that my way was plain; my only fear was that they might kill you before I could discover the place in which you were confined, and my heart sank the first night when I found that, though I whispered down every one of the gratings, I could obtain no reply.

"I had many answers, indeed, but not from you. There might be many cells besides those with openings into the temple, and were you placed in one of these I might never hear of you again. I had resolved that if the next night pa.s.sed without my being able to find you, I would inform some of those known to be friends of Hannibal that you were a prisoner, and leave it in their hands to act as they liked, while I still continued my efforts to communicate with you. You may imagine with what joy I heard your reply on the following night."

"I must have been asleep the first night," Malchus said, "and did not hear your voice."

"I feared to speak above a whisper, my lord; there are priests all night in the sanctuary behind the great image."

Day had by this time broken, and a stir and bustle commenced in front of the long line of casemates; the elephants were brought out from their stables and stood rocking themselves from side to side while their keepers rubbed their hides with pumice stone. Nessus was one of those who was appointed to make the great flat cakes of coa.r.s.e flour which formed the princ.i.p.al food of the elephants. The other Arabs busied themselves in bringing in fresh straw, which Malchus scattered evenly over the stall; heaps of freshly cut forage were placed before each elephant.

In a short time one of the Arabs took the place of Nessus in preparing the cakes, while Nessus moved away and presently went down into the town to await the coming of Malchus. By this arrangement if the superintendent of the stables came round he would find the proper number of men at work, and was not likely to notice the subst.i.tution of Malchus for Nessus, with whose face he could not yet have become familiar. By this time numbers of the townsmen were as usual coming up to the citadel to worship in the temple or to visit friends dwelling there. Malchus learned that since his escape had been known each person on entrance received a slip of bra.s.s with a stamp on it which he had to give up on leaving.

All employed in the citadel received a similar voucher, without which none could pa.s.s the gate. The time was now come when the elephants were accustomed to be taken down to the fountains in the town below, and the critical moment was at hand. The mahout had already begun to prepare his elephant for the part he was to play. It had been trumpeting loudly and showing signs of impatience and anger. The animal was now made to kneel by the door of its stable, where Malchus had already lain down at the bottom of the howdah, a piece of sacking being thrown over him by the Arabs. The two Arabs and the mahout carried the howdah out, placed it on the elephant, and securely fastened it in its position.

These howdahs were of rough construction, being in fact little more than large open crates, for the elephants after being watered went to the forage yard, where the crates were filled with freshly cut gra.s.s or young boughs of trees, which they carried up for their own use to the citadel.
