From this place post-horses were appointed to conduct us with all speed to duke Baatu, under the guidance of three Tartars. This Baatu is the most powerful prince among them, next to their emperor. We began our journey to his court on the first Tuesday in Lent, and riding as fast as we could trot, though we changed our horses twice or thrice every day, and often travelled in the night, it was Maunday Thursday before we accomplished our journey. The whole of this journey was through the land of Comania, which is all an uniform plain, watered by four large rivers. The first of these is the Dnieper or Boristhenes; on the Russian side of which the dukes Corrensa and Montij march up and down, the latter, who marches on the other side of the plains, being the more powerful of the two[1]. The second river is the Don, or Tanais of the ancients, on the banks of which a certain prince, named Tirbon, sojourns, who is married to the daughter of Baatu. The third and largest is the Volga or Rha, on which Baatu resides. The fourth is the Jaik or Rhymnus, on each bank of which a millenary commands. All these descend southwards in winter to the sea, and travel in summer up these rivers, towards the northern mountains. All these rivers, especially the Volga, abound in fish, and run into the great sea, from which the arm of St George extends past Constantinople[2]. While on the Dnieper, we travelled many days upon the ice; and on the shore of the sea we found the ice three leagues broad. Before our arrival at the residence of Baatu, two of our Tartars rode on before, to give him an account of what we had said to Corrensa. [1] It is difficult to understand the ambiguity here used, unless we suppose that the station of Montij was on the right bank of the Dnieper; while certainly that of Corrensa was on the left or north-east bank.--E. [2] The Euxine and Caspian are here confounded as one sea. It is scarcely necessary to observe, that the Dnieper and Don run into the Euxine, while the Volga and Jaik, or Ural, are discharged into the Caspian. --E.
