The thirteenth chapter of Grisebach’s Travels presents the best account which has yet been given of the chain of Skardus and Pindus: he has been the first to prove clearly, that the Ljubatrin, which immediately overhangs the plain of Kossovo at the southern border of Servia and Bosnia, is the north-eastern extremity of a chain of mountains reaching southward to the frontiers of Ætolia, in a direction not very wide of N-S.,—with the single interruption (first brought to view by Colonel Leake) of the Klissoura of Devol,—a complete gap, where the river Devol, rising on the eastern side, crosses the chain and joins the Apsus, or Beratino, on the western,—(it is remarkable that both in the map of Boué and in that annexed to Dr. Joseph Müller’s Topographical Description of Albania, the river Devol is made to join the Genussus, or Skoumi, considerably north of the Apsus, though Colonel Leake’s map gives the correct course.) In Grisebach’s nomenclature Skardus is made to reach from the Ljubatrin as its north-eastern extremity, south-westward and southward as far as the Klissoura of Devol: south of that point Pindus commences, in a continuation, however, of the same axis. In reference to the seats of the ancient Illyrians and Macedonians Grisebach has made another observation of great importance (vol. ii, p. 121). Between the north-eastern extremity, Mount Ljubatrin, and the Klissoura of Devol, there are in the mighty and continuous chain of Skardus (above seven thousand feet high) only two passes fit for an army to cross: one near the northern extremity of the chain, over which Grisebach himself crossed, from Kalkandele to Prisdren, a very high _col_, not less than five thousand feet above the level of the sea; the other, considerably to the southward, and lower as well as easier, nearly in the latitude of Lychnidus, or Ochrida. It was over this last pass that the Roman Via Egnatia travelled, and that the modern road from Scutari and Durazzo to Bitolia now travels. With the exception of these two partial depressions, the long mountain-ridge maintains itself undiminished in height, admitting, indeed, paths by which a small company either of travellers or of Albanian robbers from the Dibren, may cross (there is a path of this kind which connects Struga with Ueskioub, mentioned by Dr. Joseph Müller, p. 70, and some others by Boué, vol. iv, p. 546), but nowhere admitting the passage of an army.
