The entrance to the Chaharshamba valley is very narrow, so narrow as to preclude the possibility of any large town ever having occupied this position; but it opens out as one passes the old Kila Wali ruins where there is ample space for the old capital of Tocharistan to have existed. On the north, trailing streams descend from the Kara Bel plateau (a magnificent grass country in summer and a cold scene of windy desolation in winter), and their descent is frequently through treacherous marshes and shining salt pitfalls, making it exceedingly difficult to follow them to the plateau edge. To the south are the harder features of the Band-i-Turkistan foothills, the crest of the long black ridge of this Band being featureless and flat, as is generally the case with the boundary ridges and revetments of a plateau country. Over the Chaharshamba divide (at about 2800 feet) and into the Kaisar drainage is an introduction to a country that is beautiful with the varied beauty of low hill-tops and gentle slopes, until one either by turning north, debouches into the flat desert plains of the Oxus at Daolatabad, or continuing more easterly, arrives at Maimana, the capital of the little province of Almar, the centre of a small world of highly cultivated and populous country, and a town which must from its position represent one or other of the ancient trade centres mentioned by Idrisi. Here we leave behind the long lines of Turkman kibitkas looking like rows of black bee-hives in the snow-spread distance, and find the flat-roofed substantial houses of a settled Uzbek population, with flourishing bazaars and a general appearance of well-being inside the mud walls of the town.

Idrisi writes that Talikan is built at the foot of a mountain which is part of the Jurkan range (Band-i-Turkistan), and that it is on the "paved" route between Merv and Balkh. This at once indicates that route as an important one compared with other routes (there being a desert route across the Karabel plateau from near Panjdeh in addition to those already mentioned), although there is no sign of any serious road-making to be detected at present. Sixty miles from Talikan, on the road to Balkh, Idrisi places Karbat, a town not so large as Talikan but more flourishing and better populated. The distance reckoned along the one possible route here points to Maimana, which is just 60 miles from Talikan, but there is no other indication of identity. Karbat was a dependency of the province of Juzjan (or Jurkan, probably Guzwan), and 54 miles to the east of it was the town of Aspurkan, a small town, itself 54 miles from Balkh. Now Balkh, by any possible route, is at least 130 to 140 miles from Maimana, but if we assume Aspurkan to have been just half-way (as Idrisi makes it) between Maimana and Balkh, we find Sar-i-pul (a small place indifferently supplied with water, and thus answering Idrisi's description of Aspurkan) almost exactly in that position. In support of this identification of Aspurkan with Sar-i-pul there is the name Aspardeh close to Sar-i-pul. Other places are mentioned by Idrisi as flourishing centres of trade and industry in this singularly favoured part of Afghanistan, where the low spurs and offshoots of the Band-i-Turkistan break gently into the Oxus plains. He says that Anbar, one day's march to the south-west of Aspurkan, was a larger place than Merv-el-Rud, with vineyards and gardens surrounding it and a fair trade in cloth. There, both in summer and winter, the chief of the country resided. Two days from Aspurkan, and one from Karbat, was the Jewish colony of Yahudia, a walled town with a good commercial business. This colony is also mentioned by Ibn Haukel as situated in the district of Jurkan. From Yahudia to Shar (a small town in the hills) was one day's march. The main road south-west from Sar-i-pul has probably remained unchanged through the centuries. It runs to Balangur (? Bala Angur) and Kurchi, the former being 10 miles and the latter 30 from Sar-i-pul. Either might represent the site of Anbar. Twenty miles from Kurchi is Belchirag, and Belchirag is about 25 from Maimana. It would thus represent the site of the ancient Yahudia fairly well, whilst 25 to 30 miles from Belchirag we find Kala Shahar, a small town in the mountains, still existing. Jurkan is described as a town by Idrisi (and as a district by Ibn Haukel), built between two mountains, three short marches from Aspurkan, and Zakar is another commercial town two marches to the south-east. I should identify Jirghan of our maps with Jurkan, and Takzar with Zakar.

All this part of Afghan Turkistan is rich in agricultural possibilities. The Uzbek population of the towns and the Ersari Turkmans of the deserts beyond Shibarghan are all agriculturists, and the land is great in fruit. They are a peaceful people, hating the Afghan rule and praying for British or any other alternative. Shibarghan is an insignificant walled town with a small garrison of Afghan Kasidars; always in straits for water in the dry season. The road between Shibarghan and Sar-i-pul is flat, skirting the edge of the rolling Chol to the east of it. Sar-i-pul itself is but a small walled town in rotten repair, sheltering a few Kasidars and two guns, but no regular Afghan troops. There are a few Jews there who make and sell wine, and a few Peshawur bunniahs (shopkeepers).

From Sar-i-pul a direct road runs to Bamian and Kabul via Takzar to the south-east, and strikes the hill country almost at once after leaving Sar-i-pul. It surmounts a high divide (about 11,000 feet), and crosses the Balkh Ab valley to reach Bamian. There is another route up the Astarab stream leading to Chiras at the head of the Murghab River and into the Hazara highlands; but these were never trade routes except for local purposes. The Hazaras send down to the plain their camel hair-cloth and receive many of the necessities of life in exchange, but there is no through traffic.

The characteristics of the Astarab road are typical of this part of Afghanistan. After passing Jirghan the valley is shut in by magnificent cliffs from 700 to 1000 feet high. The vista is closed by snow peaks to the south, which, with the brilliancy of up-springing crops on the banks of the river, form a picture of almost Alpine beauty. There is, curiously enough, an entire absence of forest in the valley, but blocks of a soft white clay mixed with mica lend a weird whiteness to its walls, dazzling the eye, and making patchwork of Nature's colouring. Snakes abound in great numbers, mostly harmless, but the deadly "asp-i-mar" is amongst them. There is a yellow variety which is freely handled by the Uzbeks, who call this snake Kamchin-i-Shah-i-Murdan. About eight miles beyond Jirghan the Uzbek population ceases. From this point there are only Firozkohis and some few Taimanis who have been ejected from the Hari Rud valley for their misdeeds. They are all robbers by profession, supporting existence by slave trading. They kidnap girls and boys from the Hazara villages of the highlands and trade them to the Uzbeks in exchange for guns, ammunition, and horses. These Taimani robbers are by no means the only slave dealers. Nearly every well-to-do establishment in Afghan Turkistan has one or two Hazara slaves. The prices paid, of course, vary, but 300 krans each was paid for two girls bought in 1883. Expert native authorities have a very high opinion of the handiness of Hazara slave girls. They are good at needlework, turning out most exquisite embroidery, and they are never idle.

The narrowness of the Astarab gorge renders it impossible to follow the river along the whole of its course. The road finally leaves the valley and strikes up to the plateau on its left bank. One remarkably persistent feature in these valley formations is the existence of two plateau levels, or terraces; that immediately overlooking the valley being sometimes 100 feet lower than the second platform which is thrown back for a considerable distance, leaving a broad terrace formation between the line of its cliff edge and that bordering the stream. Occasionally there is more than one such terrace indicating former geologic floors of the valley.

On gaining the plateau level a very remarkable scene opens out—a broad green dasht, or plain, slopes away to a sharp line westwards bordered by glittering cliffs and intersected by the white line of the road. In the midst of this setting of white and green are the remains of what must once have been a town of considerable importance, which goes by the name locally of the Shahar-i-Wairan, or ancient city. Such buildings as remain are of sun-dried brick; there appears to be no indication of the usual wall or moat surrounding this city, and nothing suggestive of a canal or "karez"; nothing, in short, but scattered ruins covering about one and a half square miles. The kabristan (or graveyard) was easily recognizable, and its vast size furnished some clue to the size of the city. All history, all tradition even, about this remarkable place seems lost in oblivion; but a city of such pretensions must have had a fair place in geography from very early times. It seems improbable, however, that it could have been more than a summer residence in its palmy days, for winter at this elevation (nearly 7000 feet) and in such an exposed locality would be very severe indeed. The only indication which can be derived from Idrisi's writings is the reference to the small town in the mountains called Shah (Shahar) one day's march from the Jewish colony of Yahudia. As already explained there is a Kila Shahar some 25 to 30 miles from Yahudia (if we accept the position of Belchirag as more or less representing that place), but the Shahar-i-Wairan is nearer by some 10 miles, and fits better into the geographical scheme. I should be inclined to identify the Shahar-i-Wairan with the ancient Shahar (or Shah) and the Kila Shahar as a later development of the same place. The point, however, to be specially noted about this geographical theory is that there is no route by which camels can pass either over the Band-i-Turkistan or the mountains enclosing the Balkh Ab from the district of Sangcharak southward. The province of Sangcharak, which corresponds roughly to the ancient district of Jurkan (or Gurkan), is rich throughout, with highly cultivated valleys and a dense population, but it is a sort of geographical cul-de-sac.

Communication with the plains of the Oxus and with Balkh (by the lower reaches of the Balkh Ab) is easy and frequent, but there never could have been a khafila road over the rugged plateau land and mountains which divide it from the basin of the Helmund.

From time immemorial efforts have been made to reach Kabul by the direct route from Herat which is indicated by the remarkable lie of the Hari Rud valley. It was never recognized as a trade route, although military expeditions have passed that way; and it has always presented a geographical problem of great interest. From Herat eastwards, past Obeh as far as Daolatyar, there is no great difficulty to be overcome by the traveller, although the route diverges from the main valley for a space. Between Daolatyar and the head of Sar-i-jangal stream (which is the source and easternmost affluent of the Hari Rud) the valley is well populated and well cultivated, with abundant pasturage on the hills. But the winter here is severe. From the middle of November to the middle of February snow closes all the roads, and even after its disappearance the deep clayey tracks are impassable even for foot travellers. In the neighbourhood of a small fort called Kila Sofarak, about 40 miles from Daolatyar, there is a parting of the ways. Over the water-parting at the head of the stream by the Bakkak Pass a route leads into the Yakulang valley, a continuation of the Band-i-Amir, or river of Balkh, which, in the course of its passage through the gorges of the mountains, here forms a series of natural aqueducts uniting seven narrow and deep lakes. Inexpressibly wild and impressive is the character of the scenery surrounding those deep-set lakes in the depths of the Afghan hills.

Near the lakes are the ruins of two important towns or fortresses, Chahilburj, and Khana Yahudi. On a high rock between them are the ruins of Shahr-i-Babar the capital of kings who ruled over a country most of which must have been included in the Hazara highlands, and was probably more or less conterminous with the Bamian of Idrisi. Between the Yakulang and the Bamian valley is a high flat watershed. Looking north-west a vast broken plateau, wrinkled and corrugated by minor ranges, and scored by deep valleys and ravines, fills up the whole space from the mountains standing about the source of the Murghab and Hari Rud to the Kunduz River of Badakshan.
