From Deria-dereh another long day's ride brought him to Zirni, which he describes as the ancient capital of Ghur. From the Band-i-Baian (or Koh Siah, as he calls it) to Zirni is at least 100 miles by the very straightest road, and that would pass by Taiwara. It is clear that he did not take that road, or he could hardly have ignored so important a position as Taiwara. If he made a detour eastward he would pass through Hazara country--very mountainous, very high and difficult, and the length of the two days' journey would be nearer 150 miles than 100. To the first day's journey (as far as Deria-dereh) he gives ten hours on horseback, which in that country might represent 60 miles; but no such place as he describes, no lake with Arcadian surroundings, has been either seen or heard of by subsequent surveyors within the recognized limits of Taimani country. If it exists at all, it is to the east of the great watershed from which spring the Ghur River and the Farah Rud, hidden within the spurs of the Hazara mountains. This is just possible, for this wild and weatherbeaten country has not been so fully reconnoitred as that farther west; but it makes Ferrier's journey extraordinary for the distances covered, and fully accounts for the fact that he has preserved so little detail of this eventful ride that, practically, there is nothing of geographical interest to be learnt from it. Ferrier's description of the ruins which are to be found in the neighbourhood of Zirni and Taiwara, especially his reference to a "paved" road leading towards Ghazni, is very interesting. He is fully impressed with the beauty of the surrounding country, and what he has to say about this centre of an historical Afghan kingdom has been more or less confirmed by subsequent explorers. Only the "Ghebers" have disappeared; and the magnificent altitude of the "Chalap Dalan" mountain, described by him as one of the "highest in the world," has been reduced to comparatively humble proportions. Its isolated position, however, undoubtedly entitles it to rank as a remarkable geographical feature.
