Lemnos, or Limni, is the largest island of Thracia, and at the same time the least elevated and the most barren. You may walk for hours there without seeing a tree. Even olive-trees are not met with in the fields, and the village gardens can boast but of few fruit trees. Timber has to be procured from Thasos or the continent. Lemnos, in spite of all this, is exceedingly fertile; it produces barley and other cereals in plenty, and the pastures amongst its hills sustain 40,000 sheep. The island consists of several distinct mountain groups of volcanic origin, 1,200 to 1,500 feet in height, and separated by low plains covered with scoriæ, or by gulfs penetrating far inland. In the time of the ancient Greeks the volcanoes of Lemnos had not yet quenched their fires, for it was in one of them that Vulcan, when hurled from heaven, established his smithy, and, with the assistance of the Cyclops, forged his thunderbolts for Jupiter. About the beginning of our era Mount Mosychlos and the promontory of Chryse were swallowed up by the sea, and the vast shoals which extend from the eastern part of the island in the direction of Imbro probably mark their site. Since the disappearance of Mount Mosychlos, Lemnos has not again suffered from volcanic eruptions or earthquakes. The majority of the inhabitants are Greeks, and the Turks who have settled amongst them are being evicted by the conquered race, which is superior to them in intelligence and industry. Commerce is entirely in the hands of the Greeks. Its principal seat is at Kastro—the ancient Myrhina—which occupies a headland between two roadsteads. Sealed earth is one of the articles exported, and is found in the mountains. In ancient times it was much prized as an astringent, and is so still throughout the East. It is not considered to possess its healing qualities unless it has been collected before sunrise on Corpus Christi day. The small island of Stratio (Hagios Eustrathios) depends politically and commercially upon Lemnos. It, too, is inhabited by Greeks. As to the islands along the coast of Asia Minor, they form a portion of Turkey in Europe as far as their political administration is concerned, but geographically they belong to Asia.[26] {98} III.—TURKEY OF THE GREEKS (THRACIA, MACEDONIA, AND THESSALY). The whole of the Ægean seaboard of European Turkey is occupied by Greeks, and this proves the great influence which the sea has exercised upon the migrations of the Mediterranean nations. Thessaly, Macedonia, Chalcis, and Thrace are more or less Greek countries, and even Constantinople lies within Greece, as defined by ethnological boundaries. The geographical distribution of race there does not, in fact, coincide with the physical features of the country—its mountains, rivers, and climate. The Turkey of the Greeks is, in reality, no geographical unit, and the only tie which unites it are the waters of the Archipelago, which wash all its shores.
