Above the gonpa rises a battlemented tower, visible from a great distance. We climbed, on foot, to the level on which the edifice stands and found ourselves confronted by a large door, painted in brilliant colors, the portal of a vast two-story building enclosing a court paved with little pebbles. To the right, in one of the angles of the court, is another huge painted door, adorned with big copper rings. It is the entrance to the principal temple, which is decorated with paintings of the principal gods, and contains a great statue of Buddha and a multitude of sacred statuettes. To the left, upon a verandah, was placed an immense prayer-cylinder. All the lamas of the convent, with their chief, stood about it, when we entered the court. Below the verandah were musicians, holding long trumpets and drums. At the right of the court were a number of doors, leading to the rooms of the lamas; all decorated with sacred paintings and provided with little prayer-barrels fancifully surmounted by black and white tridents, from the points of which floated ribbons bearing inscriptions--doubtless prayers. In the centre of the court were raised two tall masts, from the tops of which dangled tails of yaks, and long paper streamers floated, covered with religious inscriptions. All along the walls were numerous prayer-barrels, adorned with ribbons. A profound silence reigned among the many spectators present. All awaited anxiously the commencement of a religious "mystery," which was about to be presented. We took up a position near the verandah. Almost immediately, the musicians drew from their long trumpets soft and monotonous tones, marking the time by measured beats upon an odd-looking drum, broad and shallow, upreared upon a stick planted in the ground. At the first sounds of the strange music, in which joined the voices of the lamas in a melancholy chant, the doors along the wall opened simultaneously, giving entrance to about twenty masked persons, disguised as animals, birds, devils and imaginary monsters. On their breasts they bore representations of fantastic dragons, demons and skulls, embroidered with Chinese silk of various colors. From the conical hats they wore, depended to their breasts long multicolored ribbons, covered with inscriptions. Their masks were white death's-heads. Slowly they marched about the masts, stretching out their arms from time to time and flourishing with their left hands spoon-shaped objects, the bowl portions of which were said to be fragments of human crania, with ribbons attached, having affixed to their ends human hair, which, I was assured, had been taken from scalped enemies. Their promenade, in gradually narrowing circles about the masts, soon became merely a confused jostling of each other; when the rolling of the drum grew more accentuated, the performers for an instant stopped, then started again, swinging above their heads yellow sticks, ribbon-decked, which with their right hands they brandished in menacing
