The names of the halting-places between Khwaja Chist and Herat are Housab, Auca, Marabad, Astarabad, Bajitan (or Najitan), and Nachan. Auca I have no hesitation in identifying with Obeh. There is a large village at Marwa which might possibly represent Marabad, and Naisan would correspond in distance with Nachan, but this is mere guesswork; to identify the others is impossible, without further examination than was undertaken when surveying the ground.

The story of the commerce of Central Asia, which centred itself in Herat in the days of Arab supremacy, has a strong claim on the student of Eastern geography, for it is only through the itineraries of these wandering Semetic merchants and travellers that we can arrive at any estimation of the peculiar phase of civilization which existed in Asia in the mediæval centuries of our era; a period at which there is good reason to suppose that civilization was as much advanced in the East as in the West. It is not the professional explorers, nor yet the missionaries (great as are their services to geography), who have opened up to us a knowledge of the world's highways and byways sufficient to lead to general map illustration of its ancient continents, so much as the everlasting pushing out of trade investigations in order to obtain the mastery of the road to wealth.

India and its glittering fame has much to answer for, but India (that is to say, the India we know, the peninsula of India) was so much more get-at-able by sea than by land even in the early days of navigation, that we do not learn so much about the passes through the mountains into India as the way of the ships at sea, and the coast ports which they visited. According to certain Arab writers large companies of Arabs settled in the borderland and coasts of India from the very earliest days. Indeed, there are evidences of their existence in Makran long before the days of Alexander; but there is very little evidence of any overland approach to India across the Indus. Hindustan, to the mediæval Arab, commenced at the Hindu Kush, and Kabul and Ghazni were "Indian" frontier towns; and the invasions and conquests of India dating back to Assyrian times include no more than the Indus basin, and were not concerned with anything farther south. The Indus, with its flanking line of waterless desert, was ever a most effectual geographical barrier.

The Arabs entered India and occupied the Indus valley through Makran, and throughout their writings we find, strangely, little reference to any of the Indian frontier passes which we now know so well. But in the north and north-west of Afghanistan, in the Seistan and the Oxus regions, they were thoroughly at home both as traders and travellers; and with the assistance of their records we can make out a very fair idea of the general network of traffic which covered High Asia. The destroying hordes of the subsequent Mongol invasions, and the everlasting raids of Turkmans and Persians on the border, have clean wiped out the greater number of the towns and cities mentioned by them, and the map is now full of comparatively modern Turkish and Persian names which give no indication whatever of ancient occupation. There are, nevertheless, some points of unmistakable identity, and from these we can work round to conclusions which justify us in piecing together the old route-map of Northern Afghanistan to a certain extent. This is not unimportant even to modern geographers. The roads of the old khafila travellers may again be the roads of modern progress. We know, at any rate, that the Arabs of 1000 years ago were much the same as the Arabs of to-day in their manners and methods. Their routes were camel routes, not horse routes, and their day's journey was as far as a camel could go in a day, which was far in the wider and more waterless spaces of desert or uninhabited country, and very much shorter when convenient halting-places occurred. These Arab itineraries are bare enumeration of place-names and approximate distances. As for any description of the nature of the road or the scenery, or any indication of altitude (which they possibly had no means of judging), there is not a trace of it; and the difficulties of transliteration in place-names are so great as to leave identification generally a matter of mere guesswork.

One of the most interesting geographical centres from which to take off is Herat, and it may be instructive to note what is said about Herat itself and its connections with the Oxus and Seistan. Herat, says Idrisi, is "great and flourishing, it is defended inside by a citadel, and is surrounded outside by 'faubourgs.' It has many gates of wood clamped with iron, with the exception of the Babsari gate, which is entirely of iron. The Grand Mosque of the town is in the midst of the bazaars.... Herat is the central point between Khorasan, Seistan, and Fars." Ibn Haukel (tenth century) mentions a gate called the Darwaza Kushk, which is evidence that Kushk was of importance in those days, though no separate mention is made of that place; and he adds that the iron gate was the Balkh gate, and was in the midst of the city. The strategical value of the position was clearly recognized.

That grand edifice, the Mosalla, with its mosques and minars, which stood outside the walls of Herat and was the glory of the town in 1883 (when it was destroyed in the interests of military defence), had no previous existence in any other form than that which was given it when it was built in the twelfth century.

Both Ibn Haukel and Idrisi mention a mountain about six miles from Herat, from which stone was taken for paving (or mill-stones), where there was neither grass nor wood, but where was a place (in Ibn Haukel's time, but not mentioned by Idrisi) "inhabited, called Sakah, with a temple or Church of Christians." Idrisi says this mountain was "on the road to Balkh, in the direction of Asfaran." This would seem to indicate that Asfaran, "on the road to Balkh," must be Parana (or Parwana), an important position about a day's march north of Herat. Ibn Haukel says nothing about the road to Balkh, which can only be northward from Herat, but merely mentions that the mountain was on the desert or uncultivated side of Herat, where was a river which had to be crossed by a bridge. This could only be south of Herat. Asfaran is also stated to be on the road to Seistan and to have had four places dependent on it, one of which was Adraskand; and the route to Asfaran from Herat is further described as three days' journey (Idrisi). Ibn Haukel also describes Asfaran as possessing four dependent towns, and places it between Farah and Herat, or south of Herat. As Adraskand[6] is a well-known place between Herat and Farah, we must assume that this is either another Asfaran, or that Idrisi has made a mistake in copying Ibn Haukel. It might possibly be represented by Parah, twenty-five miles south-west of Herat, although the limited area of cultivable ground around renders this unlikely. Subzawar would indicate a far more promising position for an important trade centre such as Asfaran must have been, and would accord better with the three days' journey from Herat of Idrisi, or the itinerary from Farah given by Ibn Haukel, while the extensive ruins around testify to its antiquity. Asfaran was almost certainly Subzawar.

Considering the interest which may once again surround the question of communications from Herat to India, it may be useful to point out that the route connecting Farah with Herat 1000 years ago remains apparently unchanged. The bridge called the Pul-i-Malun, over the Hari Rud, must have been in existence then, and there was another bridge over the Farah River one day's march below Farah, on the highway between Herat and Seistan. To the west of Herat, on the ruin-strewn road to Sarakhs, we have one or two interesting geographical propositions.

Idrisi mentions a place possessing considerable local importance "before Herat had become what it is now," about 9 miles west of Herat, called Kharachanabad. This can easily be recognized in the modern Khardozan, a walled but very ancient town, which is about 8½ miles distant. Between it and the walls of the city there is now no place of importance, nor does it appear likely, for local reasons, that there ever could have been any. Another place, called Bousik, or Boushinj (Pousheng, according to Ibn Haukel), is said to be half the size of Sarakhs, built on the flat plain 6 miles distant from the mountains, surrounded with walls and a ditch, with brick houses, and inhabitants who were commercial, rich, and prosperous, and "who drink the water of the river that runs to Sarakhs." This indicates a site on the banks of the Hari Rud. The only modern place of importance which answers this description is the ancient town of Zindajan, which is about 6 miles from the mountains, and which (according to Ferrier) still bears the name of Foosheng. This name, however, was not recognized by the Afghan Boundary Commission. "To the west of Bousik are Kharkerde and Jerkere. One reckons two days' journey to this last town, which is well populated, smaller than Kuseri, but where there is plenty of water and cultivation. From Jerkere to Kharkerde is two days' journey." These two places are obviously on the road to Nishapur. There is an ancient "haoz," or tank, below the isolated hill of Sangiduktar, near the Persian frontier, which might well represent what is left of Jerkere, and Kharkerde lies beyond it, on the road to Rue Khaf (itself a very ancient site, probably representing Rudan), near Karat. Another place which has a very ancient and troubled history is Ghurian, about thirteen miles west of Zindajan. This is readily identified as the Koure of Idrisi, which is described as twelve miles from Bousik, on the left of the high-road westward, and about three miles from it.

This corresponds exactly with Ghurian, and proves that the high-road has retained its position through ages. Koure is described as an important town, but there is no mention of walls or defences. Another place, second only in importance to Bousik, is Kouseri. It is in fact said to be equal to Bousik, and to possess "running water and gardens." There can be little doubt that this is Kuhsan (or Kusan), one of the most important towns of the Herat valley.
