steam-engine, which pumps water from a lower into an upper cistern, from whence two overshot wheels are supplied, each of which turns two pair of stones. The upper cistern being once filled with water, it passes through the wheels into the lower one, from whence it is returned to the upper by the pumps. A stream of water of one quarter or one half inch diameter, supplies the waste of evaporation, absorption, fee. This is furnished from a well by a horse. The arches of the Pont-St.-Esprit are of eighty-eight feet. Wild figs, very flourishing, grow out of the joints of the Pont-du-Gard. The fountain of Nismes is so deep, that a stone was thirteen seconds descending from the surface to the bottom. March 24. From Nismes to Arles. The plains extending from Nismes to the Rhone, in the direction of Aries, are broken in one place by a skirt of low hills. They are red and stony at first, but as you approach the Rhone, they are of a dark gray mould, with a little sand, and very good. They are in corn and clover, vines, olives, almonds, mulberries, and willow. There are some sheep, no wood, no enclosures. The high hills of Languedoc are covered with snow. At an ancient church, in the suburbs of Aries, are some hundreds of ancient stone coffins, along the road-side. The ground is thence called _Les Champs Elysees_. In a vault in a church, are some curiously wrought, and in a back yard are many ancient statues, inscriptions, &c. Within the town are a part of two Corinthian columns, and of the pediment with which they were crowned, very rich, having belonged to the ancient capitol of the place. But the principal monument here, is an amphitheatre, the external portico of which is tolerably complete. How many porticoes there were, cannot be seen; but at one of the principal gates there are still five, measuring, from out to in, seventy-eight feet, ten inches, the vault diminishing inwards. There are sixty-four arches, each of which is, from centre to centre, twenty feet, six inches. Of course, the diameter is of four hundred and thirty-eight feet; or of four hundred and fifty feet, if we suppose the four principal arches a little larger than the rest. The ground floor is supported on innumerable vaults. The first story, externally, has a tall pedestal, like a pilaster, between every two arches; the upper story, a column, the base of which would indicate it Corinthian. Every column is truncated as low as the impost of the arch, but the arches are all entire. The whole of the upper entablature is gone, and of the Attic, if there was one. Not a single seat of the internal is visible. The whole of the inside, and nearly the whole of the outside, is masked by buildings. It is supposed there are one thousand inhabitants within the amphitheatre. The walls are more entire and firm than those of the _ampitheatre_ at Nismes. I suspect its plan and distribution to have been very different from that.
