From every camp on the lake Robert rowed out with two men at right angles to the beach, sounding the depth every five minutes. By means of these radiating lines we discovered the saucer-shaped form of the lake, for, as I have already remarked, the lake bottom is on the whole very even. Now, from camp No. 215, Robert rowed out to a depth of 121 feet.

On August 2 we continued our boating excursion, while the caravan marched along the shore. All went excellently well, we heard not a word of any officials in pursuit of us, and the Tibetans placed yaks and mules at our disposal with the greatest willingness. A couple of showers fell, loud thunder rolled in Gurla Mandatta, and a violent south-westerly breeze forced us to come to a halt and wait at a place on the shore where the brook from the Nima-pendi valley debouches, forming a delta within a broken mole. Fish are plentiful in the brook, but here also the Tibetans asked us not to catch them, and we respected their wishes—only stupid and uncouth men wound the religious feelings of others. By this brook the lake receives a tribute of 49.4 cubic feet per second, while the Richung-chu entering farther to the west-south-west contributes 63.6 cubic feet.

We passed Yanggo-gompa under sail at a rather short distance, and steered straight for Tugu-gompa, picturesquely situated on a strand terrace. Here begin the long lagoons and mud embankment we had seen from the western beach, and we were carried comfortably ashore and greeted politely by a band of Hindus consisting of pilgrims and traders. A number of Tibetan shepherds from the north were staying here, where a not unimportant wool market is held every summer. A group of monks stood on the roof. Our camp was pitched close to the foot of the monastery, on the shore road, and had a fine view over the lake and Kailas behind it. At the southern wall of the convent is a yard enclosed by a stone wall, where 500 sheep were packed like herrings in a barrel, to be shorn in turn by Hindus and Botias who come from Almora and the border country in the south. The nomads receive eight annas (8d.) for every sheep, good interest on their live capital. The wool from 500 sheep is said to amount to 16 yak-loads (Illust. 249).

250. The God of the Lake rising from Tso-mavang.
Sketch by the Author.

We paid at once a visit to the monastery, where the thirteen monks and their abbot, Tabga Rinchen, received us with the greatest kindness and politeness, showed us everything, and explained to us the various temple halls. They had heard of my voyages on the lake, and had now seen with their own eyes my boat sailing before a favourable wind, and they expressed their sincere conviction that I must possess occult powers to defy with impunity the god of the holy lake. But they understood that this was owing to my friendship with the Tashi Lama, who had given me his holy blessing. The monastery Tugu-gompa is a dependency of Shibeling-gompa in Purang, and most of the monks come from there to spend three years on the lake. They own herds in Chang-tang, trade, and seem to be in good circumstances; at any rate, they help the poor pilgrims who have nothing to eat on their wanderings round Tso-mavang. They receive gifts from well-to-do pilgrims. The temple halls are picturesque, handsome and in very good order. You enter from an upper balcony into an outer hall with wall paintings, among which is a picture of Tso-mavang with the fish-god, Madö Gemo, rising from the waves (Illust. 250). He has seven water-snakes in his hair, and the lower part of his body is like a green dolphin. The lake is as deep as it is broad, and concentric rings encircle the rising god. The abbot said that the fish-god comes up to greet the god of Tso-mavang, Hlabsen Dorche Barva, who gallops in a cloud of grey fiery tongues and smoke on a pink horse, and is armed with spear, bow and quiver. In the background stands Kang-rinpoche, the holy mountain. The whole picture is wanting in perspective and proportion, but it is curious and interesting, and the Lamaist artist has done his best to idealize the holy lake by his drawing and colouring. I made a copy of this work of art, which has some relationship with our old country paintings.

From the entrance hall a small door gives access to the holiest shrine in all Tugu-gompa, namely, the hall of the lake god. He is represented only as a mask, surrounded by kadakhs, and seems to peep out from between curtains. A couple of flames burn before him and the usual bowls are placed on a stool table. No man but the monks themselves may enter this little alcove, but I obtained permission to sit on the threshold and draw a sketch of it (Illust. 251). I regarded this unknown Hlabsen Dorche Barva almost with reverence, for he ruled over my beloved lake and had been so gracious to me.

But the finest sight of all was the view from the monastery roof. The highest parts of Gurla Mandatta, here called Mama-nani or Mamo-nani, were concealed by the lower flanks, for we were too near to it, but the surface of the lake stretched out northwards to an immense distance. A lama, who had served at several different times in the convent, asserted that the lake rose 24 to 28 inches in rainy summers, and declared that eighteen years before the water had reached to the foot of the red façade of the monastery. This seemed improbable, for the distance between the lake and the monastery was 323 feet, and the foot of the convent façade (the right corner looking from the strand) lay 20.67 feet above the level of the lake. I quote these figures to enable a future explorer to determine whether the lake has risen or fallen since August 2, 1907.

I passed the next days in the monastery, sketched the lamas at their various temple services, and fell in love with this pleasant, handsome Tugu-gompa. Punso Lama, a young monk, was my particular friend, and showed me everything with the inexhaustible knowledge of a trained museum attendant. Three officials of the Devashung had established themselves in the entrance hall in the company of the four ghostly kings, and mattresses, bundles, tables, swords and guns lay or stood in profane disorder at the entrance to the dwelling of the high gods (Illusts. 252, 253, 257).

Meanwhile Robert rowed out from the southern shore, and sounded the depths down to the contour of 207 feet. On August 5, we paid a visit to Yanggo-gompa, which contains ten monks and a nun. They told me that they came from the Hor country in the north of central Tibet, and therefore call themselves Horpa, but also Dokpa; the Changpa are the nomads of Chang-tang. The abbot is from Sekiya-gompa. In the monastery’s gunkang, a dark subterranean crypt, hang masks, kadakhs, drums, spears and guns. I asked for what purpose the monks wanted the firearms, as one of their fundamental dogmas forbids them to extinguish the light of life, and they answered that with these guns many wild yaks had been killed, whose flesh had been used for human food, and that therefore the guns had been installed in a place of honour in the monastery. Yamba Tsering, a monk twenty-two years old, sat with his head against a wooden pillar, and gazed in silence at the dim light which fell into the crypt through an impluvium; he looked like a dreamer, a searcher after hidden truth (Illust. 256). Beside him sat the wrinkled nun. Both found their way into my sketch-book (Illusts. 258, 259). The foot of the monastery façade lies exactly 14¾ feet above the level of the lake, and the river Richen-chu, entering the lake behind the convent, discharges 62.15 cubic feet of water.

Yanggo-gompa was the third of the eight monasteries of the holy lake which I had visited, and I wished to see them all without exception. And I also wished to gauge all the streams falling into the lake. It fluctuates from day to day, according as there is rain or sunshine, but only by exact measurements could I arrive at the volume which is poured into the clear basin of Tso-mavang during a day of summer.
