[23] Burnes (Travels in Bokhara, ch. ii. p. 188) doubts altogether whether the Oxus had formerly a different watercourse, and, amongst other reasons, supports his view by the opinion of the natives. No one will feel surprised that I heard them assert the very contrary. Among the Turkomans there exist numerous contradictory legends in connection with the former watercourse of the Oxus. It is difficult to decide which of the three Khanats is the most fertile, especially now, when since the death of the much-lamented Conolly, nobody is able to furnish a succinct account of the nature and resources of the soil. To judge from all I have seen in my journey to Samarkand, and learned from my fellow-travellers, of Khokand, the native home of most of them, I should feel inclined to give the preference to the Khanat of Khiva in point of vegetation. The two other Khanats have more land under cultivation, but Khiva surpasses them by far in the quantity and quality of its productions, with the exception, perhaps, of fruit, which Bokhara furnishes in greater variety, and of finer flavour. Bokhara also deserves the prize with respect to all mineral productions; but the breeding of the finest cattle and horses is the exclusive property of the nomads. The land is measured by _tanab_ (cord,--a tanab is equal to sixty square yards), and in Khiva and Khokand consists of (1) _Mülk_, freehold property, which is subject to the payment of taxes; (2) _Khanlik_, arrear estates, _i.e._, such land which the Government has either reclaimed and brought under cultivation, or which has devolved upon it by confiscation and conquest. Of this land a third of the net income is claimed by the State. (3) _Yarimdji_,[24] all land that belongs to the medresse (schools), mosques, or any religious institutions, and which is liable to a fourth of the net income. The Khanlik estates in each district are under the control of a certain number of officials, called _Müshürüb_, who at the same time collect the taxes. Church property, on the contrary, is under the management of the mutevalis, as in other Islamitic countries. [24] These were formerly let on the system of half-profit, as indicated by the name. The quality of the land in general may be judged best by my stating, that the richest soil under cultivation produces one hundred batman (one batman is equal to twenty-four pounds) on a tanab, and that of least productive quality never less than sixty batman. And taking into consideration that the cultivation of the ground here, as everywhere in Asia, is done in the most negligent manner, and is in the highest degree primitive, a competent judge can easily form an idea of the great fertility of the soil.
