Bound for the seat of war, he made his way, in company with Mr. Eugene Schuyler, the American _chargé d’affaires_ at St. Petersburg, who desired to see something of Central Asia, to Kasala, a Russian town on the Syr-Daria (the ancient _Jaxartes_), where he arrived in April, 1873. He describes this town, or fort, as the entering wedge of the Russians into Central Asia. Its population, exclusive of Russian soldiers and civilians, consists of Sarts, or Tadjiks, Bokhariots, Kirghiz, and Kara-Kalpaks; all being Tartar tribes, in whom an infusion of Aryan blood has more or less modified the old Mongolian type. As for the town, it is picturesque enough to a European eye—its low mud houses, with flat roofs, windowless, and almost doorless; its bazár, where long-bearded men, in bright-coloured robes, gravely drink tea among the wares that crowd their little shops; and the strings of laden camels that stalk through its streets, presenting a novel combination. As soon as he had obtained all the information he could with respect to the movements of the Russian force, Mr. MacGahan resolved on making a dash for the Oxus, hoping to reach that river before General Kauffmann’s army had crossed it. But when the Russian authorities learned his design, they at once interfered, declaring that the journey was dangerous, if not impracticable, and must not be undertaken without leave from the Governor-General. Mr. MacGahan then resolved on pushing forward to Fort Perovsky, as if going only to Tashkent; trusting to find there an officer in command who would not be troubled by such conscientious scruples about his personal safety. No objection was made to a journey to Tashkent; Mr. MacGahan and Mr. Schuyler therefore hurried their preparations, stowed their baggage in a waggon, and themselves in a tarantass, and shaking the dust off their feet at inhospitable and suspicious Kasala, took their course along the banks of the Syr-Daria. This, the ancient Jaxartes, is one of the most eccentric of rivers. It is continually changing its bed, like a restless traveller; “here to-day, and gone to-morrow,” and gone a distance of some eight to ten miles. To adapt it to the purposes of navigation seems almost impossible, or, at all events, would be unprofitable; and the best use that could be made of its waters would be to irrigate with them the thirsty sands of the desert of Kyzil-Kum.
