(He then proceeds to give an abstract, of which the following is a part:)

“The famous Dagh bary (mountain wall) now begins at the village of Djelgan 4 versts south-west of Derbend, but we know that as late as the beginning of the last century it could be traced down to the southern gate of the city.  This ancient wall then stretches westward to the high mountains of Tabasseran (it seems the Tabarestan of Mas’udi)....  Dubois de Montpereux enumerates the following sites of remains of the wall:—­In the famous defile of Dariel, north-east of Kazbek.  In the valley of the Assai river, near Wapila, about 35 versts north-east of Dariel.  In the valley of the Kizil river, about 15 versts north-west of Kazbek.  Farther west, in the valley of the Fiag or Pog river, between Lacz and Khilak.  From this place farther west about 25 versts, in the valley of the Arredon river, in the district of Valaghir.  Finally, the westernmost section of the Caucasian Wall has been preserved, which was evidently intended to shut up the maritime defile of Gagry, on the Black Sea.”—­H.  C.]

There is another wall claiming the title of Sadd-i-Iskandar at the S.E. angle of the Caspian.  This has been particularly spoken of by Vambery, who followed its traces from S.W. to N.E. for upwards of 40 miles. (See his Travels in C. Asia, 54 seqq., and Julius Braun in the Ausland, No. 22, of 1869.)

Yule (II. pp. 537-538) says, “To the same friendly correspondent [Professor Braun] I owe the following additional particulars on this interesting subject, extracted from Eichwald, Periplus des Kasp.  M. I. 128.

“’At the point on the mountain, at the extremity of the fortress (of Derbend), where the double wall terminates, there begins a single wall constructed in the same style, only this no longer runs in a straight line, but accommodates itself to the contour of the hill, turning now to the north and now to the south.  At first it is quite destroyed, and showed the most scanty vestiges, a few small heaps of stones or traces of towers, but all extending in a general bearing from east to west....  It is not till you get 4 versts from Derbend, in traversing the mountains, that you come upon a continuous wall.  Thenceforward you can follow it over the successive ridges ... and through several villages chiefly occupied by the Tartar hill-people.  The wall ... makes many windings, and every 3/4 verst it exhibits substantial towers like those of the city-wall, crested with loop-holes.  Some of these are still in tolerably good condition; others have fallen, and with the wall itself have left but slight vestiges.’

“Eichwald altogether followed it up about 18 versts (12 miles) not venturing to proceed further.  In later days this cannot have been difficult, but my kind correspondent had not been able to lay his hand on information.
