Near Utica was founded, probably not many years later, the settlement of Hippo-Zaritis, of which the name still seems to linger in the modern Bizerta. Hippo-Zaritis stood on the west bank of a natural channel, which united with the sea a considerable lagoon or salt lake, lying south of the town. The channel was kept open by an irregular flux and reflux, the water of the lake after the rainy season flowing off into the sea, and that of the sea, correspondingly, in the dry season passing into the lake.[586] At the present time the lake is extraordinarily productive of fish,[587] and the sea outside yields coral;[588] but otherwise the advantages of the situation are not great. Two degrees further to the west, on a hill overlooking the sea, and commanding a lovely prospect over the verdant plain at its base, watered by numerous streams, was founded the colony of Hippo Regius, memorable as having been for five-and-thirty years the residence of St. Augustine. The Phoenicians were probably attracted to the site by the fertility of the soil, the unfailing supplies of water, and the abundant timber and rich iron ore of the neighbouring mountains.[589] Hippo Regius is now Bona, or rather has been replaced by that town, which lies about a mile and a half north of the ancient Hippo, close upon the coast, in the fertile tract formed by the soil brought down by the river Seybouse. The old harbour of Hippo is filled up, and the remains of the ancient city are scanty; but the lovely gardens and orchards, which render Bona one of the most agreeable of Algerian towns, sufficiently explain and justify the Phoenician choice of the site.[590]
