It was the aim of the Turkish Government and the concessionaires not only to compete with the river trade of the Tigris, but to develop the Euphrates valley as well, there being no steamer service on the latter river. With this in mind, it was decided to divert the railway beyond Bagdad from the Tigris to the Euphrates and down the valley to Basra. For a time Basra was to mark the terminus of the railway; the concession made provision, however, for the eventual construction of a branch “from Zubeir to a point on the Persian Gulf to be agreed upon between the Imperial Ottoman Government and the concessionaires.”[41] Of considerable importance was a proposed branch line from Sadijeh, on the Tigris, to Khanikin, on the Persian frontier. This railway, it was believed, would take the place of the existing caravan route from Bagdad to Khanikin and thence to Teheran. The annual value of British trade alone transported _via_ this route was estimated at about three quarters of a million pounds sterling.[42] The Bagdad Railway, as thus projected, was one of the really great enterprises of an era of dazzling railway construction. Here was a transcontinental line stretching some twenty-five hundred miles from Constantinople, on the Bosporus, to Basra, on the Shatt-el-Arab—a project greater in magnitude than the Santa Fé line from Chicago to Los Angeles or the Union Pacific Railway from Omaha to San Francisco.[43] It was a promise of the rejuvenation of three of the most important parts of the Ottoman Empire—eastern Anatolia, northern Syria, and Mesopotamia. It was to open to twentieth-century steel trains a fifteenth-century caravan route. It was to replace the camel with the locomotive. THE SULTAN LOOSENS THE PURSE-STRINGS
