The third station from Merv is Sultan-i-band, some 76 versts distant and at an altitude of 139.55 sagenes. A slight change in the character of the country is here noticeable; the flat, sandy, barren expanse which begins wherever the Yulatan oasis leaves off giving place to dense reeds and marshes. Water is not drawn from the Murghab river at this station, the supply coming from the Khani Yab canal. Originally the region was fertilised by the Sultan-i-band; but that once magnificent work has fallen into decay, and, although the surrounding country contains a large Tekke population, there is very little industry. The ruins of the Sultan-i-band lie in the immediate vicinity,--the word “band” means “dam,”--this famous canal once being connected very closely with the history of Old Merv when the waters of the Murghab irrigated that oasis. But to-day the commercial importance of the district is insignificant and in the year under review only 3689 poods of cotton were forwarded to Merv. [Illustration: ON THE CENTRAL ASIAN RAILWAY.] The environment of the next station, Imam Baba, which is 44 versts distant, reveals on account of the prevalence of malaria a very desolate appearance. It is situated where the sand-hills approach the banks of the Murghab river, but the spot is desert and marshy. It rests 148.60 sagenes above the sea, drawing its water from the Murghab river. There is little local industry and the district owing to the fever, is very scantily populated. The fifth station from Merv is Sari Yazi, where a small buffet denotes its importance. The mean gradient of the line between Merv and this point is 0.0005 and the distance is 157 versts. The depôt is situated in the Murghab valley, bounded on the east by the Karabyl hills, a low-lying ridge of sandy clay. It lies 155.57 sagenes high and depends for its water upon the Murghab river. Sari Yazi occupies an interesting region and is itself the site of an important Turcoman fortress, now in ruins. Among the valleys on the northern slopes of the Karabyl hills there are the traces of numerous Tekke villages, whose men held the region in subjection while the women cultivated the ground. At the station there are railway yards and workshops; attached to it is an hospital with fifteen beds and barracks for one company of the Railway Battalion. In 1901 there arrived: _Imports._ _Exports._ Merchandise, 9188 poods. Cotton and Merchandise, 2139 poods.
