son’s sons strove among themselves who should be king in his stead. And the son of one of his sons, who was called Abou-Thabet, obtained the mastery over them. And Abou-Thabet made peace with Abou-Zeiyan, King of Tlemçen, and led back his host to the country of Fez, whence it came. And Tlemçen had peace thirty-three years. So runs the tale of the Arab chroniclers, and the walls and towers of Mansoura stand to-day in witness that they lied not. Their entrancing story is full of the elements of Oriental romance:—the fairy city springing into being almost in a night; the fearful proposal of the aged servant that the women should be killed; the long years of the siege reaching their tremendous climax in the assassination of the aggressor at the very moment when the besieged were preparing to sell their lives dearly; the struggle of the dead Sultan’s brothers and sons and grandsons for the succession. Such a struggle is a commonplace of Mohammedan politics; we have seen it in our own day in Afghanistan and Morocco; we may see it in Turkey to-morrow. It may plunge the country where it occurs in civil war, but in a South American republic even a change of party groupings will do that. As a system it can claim some merit in that it tends to place on the throne the strongest or the most astute member of the royal house. [Illustration: THE TOWER OF MANSOURA] Of the dream city of Mansoura nothing remains but the square of the ramparts enclosing a space of 250 acres, and the great minaret of the mosque. The city itself was destroyed by the Tlemçenites after the departure of the Moroccan army. The walls are about 40 feet high, and the towers 120 feet apart. They are all built of concrete, and though broken in places, are marvellously preserved. Weathered to a delightful tint of rich brown, they contrast admirably with the sombre monotony of the olive trees; and they lend to the pleasant mountain landscape a unique spice of romance. The minaret, of which the inner portion has fallen while the outer remains standing, is a very noble tower, and the finest architectural work of Moorish times in Algeria; it would be difficult to match it anywhere. It stands about 130 feet high, and is built of hewn stone. Its front was decorated with coloured tiles, of which many are left. Legends have gathered round it. It is said that in his haste Abou Yakoub employed not only Mohammedan but Jewish and Christian masons, and that it is the work of the infidels which has fallen, while that of the faithful survives. It seems to have been also a starting-place for an early experiment in flying. A certain Jew imprisoned therein made himself wings, and setting forth on the occasion of a great service, fell lamentably at a spot called to this day “Le Col du Juif.” Such is the fate of pioneers.
