Now, in all the languages of Asia, there are many sounds as impossible to be rendered by the European letters as this, and in making the attempt every different writer falls into a different mode. Thus the first name of Genghis Khan's father is spelled by different travelers and historians, Yezonkai, Yesukay, Yessuki, Yesughi, Bissukay, Bisukay, Pisukay, and in several other ways. The real sound was undoubtedly as different from any of these as they were all different from each other. In this narrative I shall adopt the first of these methods, and call him Yezonkai Behadr. [Illustration: Map of the Empire of Genghis Khan.] Yezonkai was a great khan, and he descended in a direct line through ten generations, so it was said, from a deity. Great sovereigns in those countries and times were very fond of tracing back their descent to some divine origin, by way of establishing more fully in the minds of the people their divine right to the throne. Yezonkai's residence was at a great palace in the country, called by a name, the sound of which, as nearly as it can be represented in English letters, was _Diloneldak_. From this, his capital, he used to make warlike excursions at the head of hordes of Monguls into the surrounding countries, in the prosecution of quarrels which he made with them under various pretexts; and as he was a skillful commander, and had great influence in inducing all the inferior khans to bring large troops of men from their various tribes to add to his army, he was usually victorious, and in this way he extended his empire very considerably while he lived, and thus made a very good preparation for the subsequent exploits of his son. The northern part of China was at that time entirely separated from the southern part, and was under a different government. It constituted an entirely distinct country, and was called Katay.[A] This country was under the dominion of a chieftain called the Khan of Katay. This khan was very jealous of the increasing power of Yezonkai, and took part against him in all his wars with the tribes around him, and assisted them in their attempts to resist him; but he did not succeed. Yezonkai was too powerful for them, and went on extending his conquests far and wide. [Footnote A: Spelled variously Kathay, Katay, Kitay, and in other ways.] At last, under the pretense of some affront which he had received from them, Yezonkai made war upon a powerful tribe of Tartars that lived in his neighborhood. He invaded their territories at the head of an immense horde of Mongul troops, and began seizing and driving off their cattle.
