than 100,000 square miles.

In modern times it is customary to divide the province of Fars into the ghermsir, or, "warm district," and the serdsir, or "cold region"—and the physical character of the country must have made such a division thoroughly appropriate at every period. The "warm district" is a tract of sandy plain, often impregnated with salt, which extends between the mountains and the sea the whole length of the province, being a continuation of the flat region of Susiana, but falling very much short of that region in all the qualities which constitute physical excellence. The soil is poor, consisting of alternate sand and clay—it is ill-watered, the entire tract possessing scarcely a single stream worthy of the name of river—and, lying only just without the northern Tropic, the district is by its very situation among the hottest of western Asia. It forms, however, no very large portion of the ancient Persia, being in general a mere strip of land, from ten to fifty miles wide, and thus not constituting more than an eighth part of the territory in question.

The remaining seven eighths belong to the serdsir, or "cold region." The mountain-range which under various names skirts on the east the Mesopotamian lowland, separating off that depressed and generally fertile region from the bare high plateau of Iran, and running continuously in a direction parallel to the course of the Mesopotamian streams—i.e. from the north-west to the south-east—changes its course as it approaches the sea, sweeping gradually round between long. 50° and 55°, and becoming parallel to the coast-line, while at the same time it broadens out, till it covers a space of nearly three degrees, or above two hundred miles. Along the high tract thus created lay the bulk of the ancient Persia, consisting of alternate mountain, plain, and narrow valley, curiously intermixed, and as yet very incompletely mapped. This region is of varied character. In places richly, fertile, picturesque, and romantic almost beyond imagination, with lovely wooded dells, green mountain-sides, and broad plains suited for the production of almost any crops, it has yet on the whole a predominant character of sterility and barrenness, especially towards its more northern and eastern portions. The supply of water is everywhere scanty. Scarcely any of the streams are strong enough to reach the sea. After short courses they are either absorbed by the sand or end in small salt lakes, from which the superfluous water is evaporated. Much of the country is absolutely without streams, and would be uninhabitable were it not for the kanats, or karizes, subterranean channels of spring-water, described at length in a former volume.

The only rivers of the district which deserve any attention are the Tab (or Oroatis), whereof a description has been already given, the Kur or Bendamir (called anciently Araxes), with its tributary, the Pulwar (or Cyrus), and the Khoonazaberni or river of Khisht.

The Bendamir rises in the mountains of the Bakhtiyari chain, in lat. 30° 35', long. 51° 50' nearly, and runs with a course which is generally south-east, past the ruins of Persepolis, to the salt lake of Neyriz or Kheir, which it enters in long. 53° 30'. It receives, where it approaches nearest to Persepolis, the Pulwar or Kur-ab, a small stream coming from the north-east and flowing by the ruins of both Pasargadae and Persepolis. A little below its junction with this stream the Bendamir is crossed by a bridge of five arches, and further down, on the route between Shiraz and Herman, by another of twelve. Here its waters are to a great extent drawn off by means of canals, and are made to fertilize a large tract of rich flat country on either bank, after which the stream pursues its course with greatly diminished volume to the salt lake in which it ends. The entire course, including only main windings, may be estimated at 140 or 150 miles.

The Khoonazaberni or river of Khisht rises near the ruins of Shapur, at a short distance from Kazerun, on the route between Bushire and Shiraz, and flows in a broad valley between lofty mountains towards the south-west, entering the Persian Gulf by three mouths, the chief of which is at Rohilla, twenty miles north of Bushire, where the stream has a breadth of sixty yards, and a depth of about four feet. Above Khisht the river is already thirty yards wide. Its chief tributary is the Dalaki stream, which enters it from the east, nearly in long. 51°. The entire course of the Khisht river may be about 95 or 100 miles. Its water is brackish except near the source.

The principal lakes are the Lake of Neyriz and the Deriah-i-Nemek. The Deriah-i-Nemek is a small basin distant about ten miles from Shiraz, which receives the waters of the streams that supply that town. It has a length of about fifteen and a breadth of about three or three and a half miles. The lake of Neyriz or Kheir is of far larger size, being from fifty to sixty miles long and from three to six broad, though in the summer season it is almost entirely dried up. Salt is then obtained from the lake in large quantities, and forms an important feature in the commerce of the district. Smaller lakes, also salt or brackish, exist in other parts of the country, as Lake Famur, near Kazerun, which is about six miles in length, and from half a mile to a mile across.

The most remarkable feature of the country consists in the extraordinary gorges which pierce the great mountain-chain, and render possible the establishment of routes across that tremendous barrier. Scarped rocks rise almost perpendicularly on either side of the mountain-streams, which descend rapidly with frequent cascades and falls. Along the slight irregularities of these rocks the roads are carried in zigzags, often crossing the streams from side to side by bridges of a single arch, which are thrown over profound chasms where the waters chafe and roar many hundred feet below. [PLATE XXVI.] The roads have for the most part been artificially cut in the sides of the precipices, which rise from the streams sometimes to the height of 2000 feet. In order to cross from the Persian Gulf to the high plateau of Iran, no fewer than three or four of these kotuls, or strange gorge-passes, have to be traversed successively. Thus the country towards the edge of the plateau is peculiarly safe from attack, being defended on the north and east by vast deserts, and on the south by a mountain-barrier of unusual strength and difficulty.

It is in these regions, which combine facility of defence with pleasantness of climate, that the principal cities of the district have at all times been placed. The earliest known capital of the region was Pasargadae, or Persagadae, as the name is sometimes written, of which the ruins still exist near Murgab, in lat. 30° 15' long. 53° 17'. Here is the famous tomb of Cyrus, whereof a description will be given hereafter; and here are also other interesting remains of the old Persian architecture. Neither the shape nor the extent of the town can be traced. The situation was a plain amid mountains, watered by small streams which found their way to a river of some size (the Pulwar) flowing at a little distance to the west. [PLATE XXVII Fig. 1.]
