We reached Tekrit in three days without accident or adventure. Bedouin tents and moving swarms of men and animals were occasionally seen on the river banks, but under the protection of our Sheikh we met with no hindrance. Tekrit is almost the only permanent settlement of any importance between Mosul and Baghdad. It is now a small town, but was once a place of some size and strength. Tekrit is chiefly famous as the birthplace of the celebrated Saleh-ed-din, better known to the English reader as Saladin, the hero of the crusades, and the magnanimous enemy of our Richard Coeur-de-Lion. His father, Ayub, a chief of a Kurdish tribe of Rahwanduz, was governor of its castle for the Seljukian monarchs of Persia. Mosul itself sustained a siege from Saladin, who was repulsed by its Atabeg, or hereditary prince. Military expeditions into the Sinjar and other parts of Mesopotamia were amongst the exploits of this great Mussulman hero. Tekrit is now inhabited by a few Arabs, who carry on, as raftsmen, the traffic of the river between Mosul and Baghdad. Nothing marks more completely the results of the unjust and injurious system pursued by the Porte in its Arabian territories than the almost entire absence of permanent settlements and of commercial intercourse on the banks of the Euphrates and Tigris. Two of the finest rivers of Asia, reaching into the very heart of the Turkish dominions, spreading fertility through districts almost unequalled for the richness of their soil and for the varied nature of their produce, and navigable one for nearly 850 miles from the sea, the other for nearly 600 miles, are of no account whatever to the State upon which nature has conferred such eminent advantages. The depredations of the Arabs, unchecked by the government, and the rapacity and dishonesty of the Turkish authorities, who levy illegal and exorbitant taxes upon every mode of transit whether by land or water, and who make monopolies of all articles of produce and of merchandise, effectually check the efforts of the natives themselves, by no means deficient in commercial activity and enterprise, to engage in trade, or to navigate the rivers. Even the European merchant, with privileges secured by treaties, and protection afforded by consuls and diplomatic agency, is scarcely able to struggle against the insecurity of the country through which he must convey his goods, and against the black-mail exacted by Arab Sheikhs, secretly encouraged or abetted by the Turkish governors. From the most wanton and disgraceful neglect, the Tigris and Euphrates, in the lower part of their course, are breaking from their natural beds, forming vast marshes, turning fertile districts into a wilderness, and becoming unnavigable to vessels of even the smallest burden.
