Hippo was the next place to be attacked. After Carthage and Utica—the Roman head-quarters were at Utica—Hippo was the largest and most important town in Northern Africa. Its docks, its harbour, its walls were on a grand scale. Two hundred years before, Agathocles, tyrant of Syracuse, in his desperate struggle with Carthage had made it the base of his operations. A lavish expenditure, directed by the best engineers of the time, had made it almost impregnable.

The Roman generals had, indeed, excellent reasons for attacking it. Till it was in their power, they could hardly hope to capture Carthage, for it stood almost between their own head-quarters and that city, and commanded the route by which stores had to be carried to the besieging army. But the Roman forces were quite unequal to the undertaking. Twice did the people of Hippo, helped by a sally from Carthage, destroy the siege-works, and when the time for retiring to winter quarters arrived, nothing had been accomplished by the besiegers.

All this did vast damage to the prestige of the Romans. Far-seeing persons were convinced, as I have said, that the future belonged to them; but ordinary observers began to think, and not without some excuse, that their decline had begun. Among these were two out of three sons of King Masinissa. Possibly dissatisfaction had something to do with their state of mind. Each had expected to get more than Scipio's award had given him; both grudged to Gulussa the command of the troops, suspecting that this meant in the end their own subjection to him. Gulussa himself seemed to be still loyal to Rome, but the general discontent had not failed to reach some of the high-placed officers in his army.

Cleanor was still with Mastanabal, and, of course, watched the progress of affairs with intense interest. His hopes rose high when tidings reached the palace that the Romans had abandoned the siege of Hippo. At the evening meal that day the subject was discussed, but in a very guarded way, for the prince was still, at least in name, an ally of Rome, and his young secretary, for this was the office which Cleanor now filled, was too discreet to ignore the fact. The hour for retiring had almost come when the confidential slave who waited on the prince hurriedly entered the chamber and placed a letter in his hands. It was a double tablet closely bound together with cords of crimson silk, these again being secured by seals. Hastily cutting the cords with the dagger which he carried at his waist, the prince read the communication with that impassive and inscrutable look which it is one of the necessities of a despotic ruler to acquire. Rising shortly after from table he bade the young Greek good-night, but added, as if by an after-thought, "But stay, I have a book, a new acquisition, to show you. Come into the library."

The library was a small inner room, of a semicircular shape, which opened out of the dining-hall. It had this great advantage, contemplated, no doubt, by the builder who designed it, that conversations held in it could not by any possibility be overheard. It had an outer wall everywhere except on the side which adjoined the dining-hall. It was built on columns, so that no one could listen beneath, and there was no storey over it. As long as the outer chamber was empty, absolute secrecy was ensured. Only a bird of the air could carry the matters discussed in it.

"Listen, Cleanor," said the prince, and proceeded to read the following letter:—

Hasdrubal, son of Gisco, to King Mastanabal greeting. Know that if you would save Africa, now, and now only, you have the opportunity. The Romans have fled from Hippo fewer by a third than when they first attacked it. Bithyas, commander of Gulussa's cavalry, has come over to us with seven hundred of his best troopers. Strike then along with us such a blow as shall rid us of this devouring Beast now and for ever. Else you shall yourself surely be devoured. Think not that when Carthage is destroyed, there shall be any hope left for Numidia. Farewell!

"What think you of this, Cleanor?" the king asked after a pause. "I know well enough that you have no liking for the Romans. Indeed, why should you? But you can judge of how things stand, judge, doubtless, better in some ways than I can, for there are many things that we kings never see. Speak frankly. No one can overhear us."

"Sire," replied the young Greek, "it wants, I fear, more wisdom than I possess to give you any profitable counsel. I hate Rome, but I fear her. She makes blunders without number, but always manages to succeed in the end. She chooses mere fools and braggarts for her generals, but always finds the right man at last. So I read her history. There was a time when everyone believed that Hannibal would make an end of her, and yet she survived. She lost army after army, yet conquered in the end. After a Flaminius and a Varro[8] she found a Scipio. And she has a Scipio now. I saw him, sire, the other day, and felt that he was a great man."

"But he is too young," interrupted the king. "He wants some five years yet of the age when he can be put in chief command."
