Illustration—LACHOONG VALLEY AND VILLAGE, LOOKING SOUTH.
Stupendous moraines rise 1500 feet above the Lachoong in several concentric series, curving downwards and outwards, so as to form a bell-shaped mouth to the valley of the Tunkrachoo. Those on the upper flank are much the largest; and the loftiest of them terminates in a conical hill crowned with Boodhist flags, and its steep sides cut into horizontal roads or terraces, one of which is so broad and flat as to suggest the idea of its having been cleared by art.

SOUTH-EAST.
On the south side of the Tunkrachoo river the moraines are also more or less terraced, as is the, floor of the Lachoong valley, and its east slopes, 1000 feet up.* [I have since been greatly struck with the similarity between the features of this valley, and those of Chamouni (though the latter is on a smaller scale) above the Lavanchi moraine. The spectator standing in the expanded part below the village of Argentiere, and looking upwards, sees the valley closed above by the ancient moraine of the Argentiere glacier, and below by that of Lavanchi; and an all sides the slopes are cut into terraces, strewed with boulders. I found traces of stratified pebbles and sand on the north flank of the Lavanchi moraine however, which I failed to discover in those of Lachoong. The average slope of these pine-clad Sikkim valleys much approximates to that of Chamouni, and never approaches the precipitous character of the Bernese Alps' valleys, Kandersteg, Lauterbrunnen, and Grindelwald.]
The river is fourteen yards broad, and neither deep nor rapid: the village is on the east bank, and is large for Sikkim; it contains fully 100 good wooden houses, raised on posts, and clustered together without order. It was muddy and intolerably filthy, and intersected by some small streams, whose beds formed the roads, and, at the same time, the common sewers of the natives. There is some wretched cultivation in fields,* [Full of such English weeds as shepherd's purse, nettles, Solanum nigrum, and dock; besides many Himalayan ones, as balsams, thistles, a beautiful geranium, mallow, Haloragis and Cucurbitaceous plants.] of wheat, barley, peas, radishes, and turnips. Rice was once cultivated at this elevation (8000 feet), but the crop was uncertain; some very tropical grasses grow wild here, as Eragrostis and Panicum. In gardens the hollyhock is seen: it is said to be introduced through Tibet from China; also Pinus excelsa from Bhotan, peaches, walnuts, and weeping willows. A tall poplar was pointed out to me as a great wonder; it had two species of Pyrus growing on its boughs, evidently from seed; one was a mountain ash, the other like Pyrus Aria.
Soon after camping, the Lachoong Phipun, a very tall, intelligent, and agreeable looking man, waited on me with the usual presents, and a request that I would visit his sick father. His house was lofty and airy: in the inner room the sick man was stretched on a board, covered with a blanket, and dying of pressure on the brain; he was surrounded by a deputation of Lamas from Teshoo Loombo, sent for in this emergency. The principal one was a fat fellow, who sat cross-legged before a block-printed Tibetan book, plates of raw meat, rice, and other offerings, and the bells, dorje, etc. of his profession. Others sat around, reading or chanting services, and filling the room with incense. At one end of the apartment was a good library in a beautifully carved book-case.

The Singtam Soubah being again laid up here from the consequences of leech-bites, I took the opportunity of visiting the Tunkra-lah pass, represented as the most snowy in Sikkim; which I found to be the case. The route lay over the moraines on the north flank of the Tunkrachoo, which are divided by narrow dry gullies,* [These ridges of the moraine, separated by gullies, indicate the progressive retirement of the ancient glacier, after periods of rest. The same phenomena may be seen, on a diminutive scale, in the Swiss Alps, by any one who carefully examines the lateral and often the terminal moraines of any retiring or diminishing glacier, at whose base or flanks are concentric ridges, which are successive deposits.] and composed of enormous blocks disintegrating into a deep layer of clay. All are clothed with luxuriant herbage and flowering shrubs,* [Ranunculus, Clematis, Thalictrum, Anemone, Aconitum variegatum of Europe, a scandent species, Berberry, Deutzia, Philadelphus, Rose, Honeysuckle, Thistles, Orchis, Habenaria, Fritillaria, Aster, Calimeris, Verbascum thapsus, Pedicularis, Euphrasia, Senecio, Eupatorium, Dipsacus, Euphorbia, Balsam, Hypericum, Gentiana, Halenia, Codonopsis, Polygonum.] besides small larches and pines, rhododendrons and maples; with Enkianthus, Pyrus, cherry, Pieris, laurel, and Goughia. The musk-deer inhabits these woods, and at this season I have never seen it higher. Large monkeys are also found on the skirts of the pine-forests, and the Ailurus ochraceus (Hodgs.), a curious long-tailed animal peculiar to the Himalaya, something between a diminutive bear and a squirrel. In the dense and gigantic forest of Abies Brunoniana and silver fir, I measured one of the former trees, and found it twenty-eight feet in girth, and above 120 feet in height. The Abies Webbiana attains thirty-five feet in girth, with a trunk unbranched for forty feet.
