82° 30’. It begins by flowing to the north-west, in a direction parallel to that of the Western Himalayas, along the northern flank of which it continues in this line a distance of about 700 miles, past Ladak, to long. 75° nearly. Here it is met by the Bolor chain, which prevents its further progress in this direction and causes it to turn suddenly nearly at a right angle to the south-west. Entering a transverse valley, it finds a way (which is still very imperfectly known) through the numerous ridges of the Himalaya to the plain at its southern base, on which it debouches about thirty miles above Attock. It is difficult to say at what exact point it crossed the Persian frontier, but probably at least the first 700 miles of its course were through territory not Persian. From Attock to the sea the Indus is a noble river. It runs for 900 miles in a general direction of S.S.W. through the plain in one main stream (which is several hundred yards in width), while on its way it throws off also from time to time small side streamlets, which are either consumed in irrigation or rejoin the main channel. A little below Tatta its Delta begins—a Delta, however, much inferior in size to that of the Nile. The distance from the apex to the sea is not more than sixty miles, and the breadth of the tract embraced between the two arms does not exceed seventy miles. The entire course of the Indus is reckoned at 1960 miles, of which probably 1260 were through Persian territory. The volume of the stream is always considerable, while in the rainy season it is very great. The Indus is said then to discharge into the Indian ocean 446,000 cubic feet per second, or 4280 millions of cubic yards in the twenty-four hours.

      The Oxus rises from an Alpine lake, lying on the western side of the Bolor chain in lat. 37° 40’, long. 73° 50’. After a rapid descent from the high elevation of the lake, during which it pursues a somewhat serpentine course, it debouches from the hills upon the plain about long. 69° 20’, after receiving the river of Fyzabad, and then proceeds, first west and afterwards north-west, across the Great Kharesmian Desert to the Sea of Aral. During the first 450 miles of its course, while it runs among the hills, it receives from both sides numerous and important tributaries; but from the meridian of Balkh those fail entirely, and for above 800 miles the Oxus pursues its solitary way, unaugmented by a single affluent, across the waste of Tartary, rolling through the desert a wealth of waters, which must diminish, but which does not seem very sensibly to diminish, by evaporation. At Kilef, sixty miles north-west of Balkh, the width of the river is 350 yards; at Khodja Salih, thirty miles lower down, it is 823 yards with a depth of twenty feet; at Kerki, seventy miles below Khodja Salih, it is “twice the width of the Danube at Buda-Pesth,” or about 940 yards; at Betik, on the route between Bokhara and Merv, its width has diminished to 650 yards, but its depth has increased to twenty-nine feet. Finally, at Gorlen Hezaresp near Khiva, the breadth of the Oxus is so great that both banks are hardly distinguishable at the same time; but the stream is here comparatively shallow, ceasing to be navigable at about this point. The present course of the Oxus from its rise in Lake Sir-i-Kol to its termination in the Sea of Aral is estimated at 1400 miles. Anciently its course must have been still longer. The Oxus, in the time of the Achaemenian kings, fell into the Caspian by a channel which can even now be traced. Its length was thus increased by at least 450 miles, and, exceeding that of the Jaxartes, fell but little short of the length of the Indus.

      The Oxus, like the Nile and the Indus, has a periodical swell, which lasts from May to October. It does not, however, overflow its hanks. Under a scientific system of irrigation it is probable that a considerable belt of land on either side of its course might be brought under cultivation. But at present the extreme limit to which culture is carried, except in the immediate vicinity of Khiva, seems to be four miles; while often, in the absence of human care, the desert creeps up to the very brink of the river.

      The Jaxartes, or Sir-Deria, rises from two sources in the Thian-chan mountain chain, the more remote of which is in long. 79° nearly. The two streams both flow to the westward in almost parallel valleys, uniting about long. 71°. After their junction the course of the stream is still to the westward for two degrees; but between Khokand and Tashkend the river sweeps round in a semicircle and proceeds to run first due north and then north-west, skirting the Kizil Koum desert to Otrar, where it resumes its original westerly direction and flows with continually diminishing volume across the desert to the Sea of Aral. The Jaxartes is a smaller stream than the Oxus. At Otrar, after receiving its last tributary, it is no more than 250 yards wide. Below this point it continually dwindles, partly from evaporation, partly from the branch stream which it throws off right and left, of which the chief are the Cazala and the Kuvan Deria. On its way through the desert it spreads but little fertility along its banks, which are in places high and arid, in others depressed and swampy. The branch streams are of some service for irrigation; and it is possible that a scientific system might turn the water of the main channel to good account, and by its means redeem from the desert large tracts which have never yet been cultivated. But no such system has hitherto been applied to the Sir, and it is doubtful whether success would attend it. The Sir, where it falls into the Sea of Aral, is very shallow, seldom even in the flood season exceeding four feet. The length of the stream was till recently estimated at more than 1208 miles; but the latest explorations seem to require an enlargement of this estimate by at least 200 or 250 miles.

      In rivers of the second class the Persian Empire was so rich that it will be impossible, within the limits prescribed for the present work, to do more than briefly enumerate them. The principal were, in Asia Minor, the Hermus (Ghiediz Chai), and the Maeander (Mendere) on the west, the Sangarius (Sakka-riyeh), the Halys (Kizil Irmak), and the Iris (Yechil Irmak) on the north, the Cydnus (Tersoos Chai), Sarus (Cilician Syhun), and Pyramus (Cilician Jyhun) on the south; in Armenia and the adjacent regions, the Araxes (Aras), Cyrus (Kur), and Phasis (Eion); on the Iranic plateau, the Sefid-rud, the Zenderud or river of Isfahan, the Etymandrus (Helmend), and the Arius (Heri-rud); in the low country east of the Caspian, the Gurgan and Ettrek, rivers of Hyrcania, the Margus Churghab (or river of Merv), the Delias or river of Balkh, the Ak Su or Bokhara river, and the Kizil Deria, a stream in the Khanat of Kokand; in Afghanistan and India, the Kabul river, the Hydaspes (Jelum), the Aoesines (Chenab), the Hydraotes (Ravee), and the Hyphasis (Sutlej or Gharra); in Persia Proper, the Oroatis (Hindyan or Tab), and the Bendamir; in Susiana, the Pasitigris (Kuran), the Hedypnus (Jerahi), the Choaspes (Kerkhah), and the Eulsenus (a branch of the same); in the Upper Zagros region, the Gyndes (Diyaleh), and the Greater and Lesser Zabs; in Mesopotamia, the Chaboras (Kha-bour), and Bilichus (Belik); finally, in Syria and Palestine, the Orontes or river of Antioch (Nahr-el-asy), the Jordan, and the Barada or river of Damascus. Thus, besides the six great rivers of the Empire, forty other considerable streams fertilized and enriched the territories of the Persian monarch, which, though they embraced many arid tracts, where cultivation was difficult, must be pronounced upon the whole well-watered, considering their extent and the latitude in which they lay.

      The Empire possessed, besides its rivers, a number of important lakes. Omitting the Caspian and the Aral, which lay upon its borders, there were contained within the Persian territories the following important basins: the Urumiyeh, Lake Van, and Lake Goutcha or Sivan in Armenia; Lakes Touz-Ghieul, Egerdir, Bey-Shehr, Chardak, Soghla, Buldur, Ghieul-Hissar, Iznik, Abullionte, Maniyas, and many others in Asia Minor; the Sabakhah, the Bahr-el-Melak, and the Lake of Antioch in Northern Syria; the Lake of Hems in the Coele-Syrian valley; the Damascus lakes, the Lake of Merom, the Sea of Tiberias, and the Dead Sea in Southern Syria and Palestine; Lake Moeris and the Natron lakes in Egypt; the Bahr-i-Nedjif in Babylonia; Lake Neyriz in Persia Proper; the Lake of Seistan in the Iranic Desert; and Lake Manchur in the In dus valley. Several of these have been already described in these volumes. Of the remainder the most important were the Lake of Van, the Touz-Ghieul, the great lake of Seistan, and Lake Moeris. These cannot be dismissed without a brief description.

      Lake Van is situated at a very unusual elevation, being more than 5400 feet above the sea level. It is a triangular basin, of which the three sides front respectively S.S.E., N.N.E., and N.W. by W. The sides are all irregular, being broken by rocky promontories; but the chief projection lies to the east of the lake, where a tract is thrown out which suddenly narrows the expanse from about fifty miles to less than five. The greatest length of the basin is from N.E. to S.W., where it extends a distance of eighty miles between Amis and Tadvan; its greatest width is between Aklat and Van, where it measures across somewhat more than fifty miles. The scenery which surrounds it is remarkable for its beauty. The lake is embosomed amid high mountains, picturesque in outline, and all
