Of all the countries of Europe there is none possessed of natural advantages to enable it to compare with those constituting the TURKISH EMPIRE in Europe and Asia. Wool and silk, corn, oil, and tobacco, might, with proper cultivation, be produced in almost unlimited quantity, while Thessaly and Macedonia, long celebrated for the production of cotton, abound in lands uncultivated, from which it might be obtained in sufficient extent to clothe a large portion of Europe. Iron ore abounds, and in quality equal to any in the world, while in another part of the empire "the hills seem a mass of carbonate of copper."[50] Nature has done every thing for the people of that country, and yet of all those of Europe, the Turkish rayah approaches in condition nearest to a slave; and of all the governments of Europe, that of Portugal even not excepted, that of Turkey is the most a slave to the dictation, not only of nations, but even of bankers and traders. Why it is so, we may now inquire. By the terms of the treaty with England in 1675, the Turkish government bound itself to charge no more than three per cent. duty on imports,[51] and as this could contribute little to the revenue, that required to be sought elsewhere. A poll-tax, house-tax, land-tax, and many other direct taxes, furnished a part of it, and the balance was obtained by an indirect tax in the form of export duties; and as the corn, tobacco, and cotton of its people were obliged to compete in the general markets of the world with the produce of other lands, it is clear that these duties constituted a further contribution from the cultivators of the empire in aid of the various direct taxes that have been mentioned. So far as foreigners were interested, the system was one of perfect free trade and direct taxation. For many years, Turkey manufactured much of her cotton, and she exported cotton-yarn. Such was the case so recently as 1798, as will be seen by the following very interesting account of one of the seats of the manufacture:--
