See also:KHORASAN, or KHORASSAN (i.e. " See also:land of the See also:sun ") , a See also:geographical See also:term originally applied to the eastern of the four quarters (named from the See also:cardinal points) into which the See also:ancient See also:monarchy of the Sassanians was divided . After the Arab See also:con-quest the name was retained both as the designation of a definite See also:province and in a looser sense . Under the new See also:Persian See also:empire the expression has gradually become restricted to the See also:north-eastern portion of See also:Persia which forms one of the five See also:great provinces of that See also:country . The province is conterminous E. with See also:Afghanistan, N. with See also:Russian Transcaspian territory, W. with See also:Astarabad and See also:Shahrud-Bostam, and S. with See also:Kerman and See also:Yezd . It lies mainly within 29° 45'–38° 15' N. and 56°–61° E., extending about 320 M. See also:east and See also:west and 570 M. north and See also:south, with a See also:total See also:area of about 150,000 sq. m . The See also:surface is mountainous . The ranges generally run in parallel ridges, inclosing extensive valleys, with a normal direction from N.W. to S.E . The whole of the north is occupied by an extensive highland See also:system composed of a See also:part of the See also:Elburz and its continuation extending to the See also:Paropamisus . This system, sometimes spoken of collectively as the Kuren Dagh, or Kopet Dagh from its See also:chief sections, forms in the east three ranges, the Hazar Masjed, Binalud Kuh and Jagatai, enclosing the See also:Meshed-See also:Kuchan valley and the Jovain See also:plain . The former is watered by the Kashaf-rud (See also:Tortoise See also:River), or river of Meshed, flowing east to the Hari-rud, their junction forming the Tejen, which sweeps See also:round the Daman-i-Kuh, or See also:northern skirt of the See also:outer range, towards the See also:Caspian but loses itself in the See also:desert See also:long before reaching it . The Jovain plain is watered by the See also:Kali-i-mura, an unimportant river which flows south to the Great Kavir or central depression . In the west the northern See also:highlands develop two branches: (I) the Kuren Dagh, stretching through the Great and Little Balkans to the Caspian at See also:Krasnovodsk See also:Bay, (2) the See also:Ala Dagh, forming a continuation of the Binalud Kuh and joining Oahe mountains between Bujnurd and Astarabad, which See also:form part of the Elburz system . The Kuren Dagh and Ala Dagh enclose the valley of the See also:Atrek River, which flows west and south-west into the Caspian at See also:Hassan Kull Bay . The western off-shoots of the Ala Dagh in the north and the mountains of Astarabad in the south enclose the valley of the Gurgan River, which also flows westwards and parallel to the Atrek to the south-eastern corner of the Caspian . The outer range has probably a mean See also:altitude of 8000 ft., the highest known summits being the Hazar Masjed (10,500) and the Kara Dagh (98o0) . The central range seems to be higher, culminating with the Shah-Jehan Kuh (r1,000) and the Ala Dagh (11,500) . The See also:southern ridges, although generally much See also:lower, have the highest point of the whole system in the Shah Kuh (13,000) between Shahrud and Astarabad . South of this northern highland several parallel ridges run diagonally across the province in a N.W.–S.E. direction as far as See also:Seistan . Beyond the Atrek and other See also:rivers watering the northern valleys a few brackish and intermittent rivers lose themselves in the Great Kavir, which occupies the central and western parts of the province . The true See also:character of the kavir, which forms the distinctive feature of east Persia, has scarcely.been determined, some regarding it as the See also:bed of a dried-up See also:sea, others as See also:developed by the saline streams draining to it from the surrounding high-lands . See also:Collecting in the central depressions, which have a mean See also:elevation of scarcely more than 500 ft. above the Caspian, the See also:water of these streams is supposed to form saline deposits with a thin hard crust, beneath which the moisture is retained for a considerable See also:time, thus producing those dangerous and slimy quagmires which in See also:winter are covered with brine, in summer with a treacherous incrustation of See also:salt . Dr Sven Hedin explored the central depressions in 1906 . The surface of See also:Khorasan thus consists mainly of highlands, saline, swampy deserts and upland valleys, some fertile and well-watered . Of the last, occurring mainly in the north, the chief are the See also:longitudinal valley stretching from near the See also:Herat frontier through Meshed, Kuchan and See also:Shirvan to Bujnurd, the Derrehgez See also:district, which lies on the northern skirt of the outer range projecting into the Akhal Tekkeh domain, now Russian territory, and the districts of See also:Nishapur and See also:Sabzevar which See also:lie south of the Binalud and Jagatai ranges .
These fertile tractsproduce See also:rice and other cereals, See also:cotton, See also:tobacco, See also:opium and fruits in profusion
.
Other products are See also:manna, suffron, asafoetida and other gums
.
The chief manufactures are swords, See also: (A . |
