Lead, zinc, and silver are found, too, in the Karahissar area, where is the argentiferous lead mine of Bukar-Dagh, once a State property. Before the war a French company of the same type as the one above mentioned, the Syndicate of Ak-Dagh, had obtained the right to explore the layers of zinc and argentiferous lead in the vilayet of Angora. The mines of Balia-Karaidin (argentiferous lead and lignite) lying north-east of the Gulf of Adramyti in the sanjak of Karassi, are controlled by French capital. The English syndicate Borax Consolidated has the concession of the boracite mines in the same sandjak. The range of Gumich-Dagh, or “Silver Mountain,” contains much emery. At Eskishehr there are mines of meerschaum, and in the Brusa vilayet quarries of white, pink, and old-blue marble, lapis-lazuli, etc. A few years ago gold layers were being exploited at Mender-Aidin, near Smyrna, and others have been found at Chanak-Kale, near the Dardanelles. Some gold-mines had been worked in Arabia in remote ages. There are oil-fields throughout the peninsula, lying in four parallel lines from the north-west to the south-east. The best-known fields are in the provinces of Mosul and Baghdad, where nearly two hundred have been identified; others have also been found near the Lake of Van, and at Pulk, west of Erzerum, which are not inferior to those of Mesopotamia; and others fifty miles to the south of Sinope. There are almost inexhaustible layers of excellent asphalt at Latakieh, on the slopes of the Libanus, and others, quite as good, at Kerkuk, Hit, and in several parts of Mesopotamia. Finally, some coal-mines are being worked at Heraclea which are controlled by French capital, and coal outcrops have been found lately in the Mosul area near the Persian frontier, between Bashkala and Rowanduz and Zahku, close to the Baghdad Railway. But the treaty, as will be shown later on, is to deprive Turkey of most of these sources of wealth. Among the other products of Turkey may be mentioned carpets, furs (fox, weasel, marten, and otter), and, particularly, silks. The silks of Brusa are more valuable than those of Syria—the latter being difficult to wind; their output has decreased because many mulberry-trees were cut down during the war, but the industry will soon resume its importance.
