ARIANNA, a small village six miles N. E. from the city of Tunis. Here is a beautiful range of the ancient Carthaginian aqueduct, 74 feet high, supported by columns 16 feet square, and which still increased in grandeur the nearer it approached Carthage. The stones are all diamond-cut. Near this spot several ancient mattamones, or subterraneous magazines for corn, have been discovered within these few years, capable of containing 100 bushels, strongly arched with large square stones. The Moors have already begun to demolish them, it being their custom to do so with every thing beautiful as soon as it comes to light.
