time sought the wicked Bo,* and at last discovered his dwell- ing-place, by seeing a grey horse (Boro moren) standing in the valley of the Kiver Arkhuin Borol, on which Tain Terkhen rode. Genghis Khan smote the shaman, striking him with his sword on the right cheek. Even now on the rock may be seen the mark of the sabre stroke.
According to the account of Tabuin-sakhal, a shaman who -lived in the town of Cobdo, two tribes, Khar darkhat and Shar Terkhen, reside in the neighbourhood of Tain Terkhen.
The figure of Tain Terkhen enjoys the greatest fame in Mongolia. To the rock travel pilgrims from places such as Wrga in the far west, from the Diubrut Vlus (villages) by the Ubsanor Lake. Even in the Gobi desert this rock is known of. It is remarkable that persons dwelling in the farthest parts of Mongolia in speaking of it always observe, " Round Tain Terkhen are many trembling shamans." Aivoha, a Mongoe who was our (Potanin's) guide across Gobi, and who was taken from a village of Nam, which is on the southern boundary of Gobi, knew of two Terkhens ; one was a blue rock (Khu khu chelo) in the country of Telengeten Uryankhai ; the other was whitish -grey ( Boro tsagan) on the Seleuge River. The Mongoes say that the image (Keshachelo) first laid upon the ground but that it raised itself up and stands now solid and upright. They say, also, that in front of Tain Terkhen can only serve a true shaman, a false shaman will at once reveal himself and die. All these tales induce me (Potanin) to imagine that in front of Tain Terkhen there is still preserved a religious service of shamans.
When I asked for representation of Tain Terkhen, they brought me, printed on a sort of paper with Indian ink, the portrait of a horseman with a standard in the right hand. The horseman was provided with a quiver and a sword. Clouds surrounded the horse- man ; at the top amidst the clouds were mountain-peaks, and below them the sun and the moon ; on the feet of the horseman were observed two statues. Other Mongoes to whom I showed the portrait called it Dainsuin Tenger.
