Towards Lamteng, the path left the river, and passed through a wood of Abies Smithiana.[[149]] Larch appears at 9000 feet, with Abies Brunoniana. An austere crab-apple, walnut, and the willow of Babylon (the two latter perhaps cultivated), yellow jessamine and ash, all scarce trees in Sikkim, are more or less abundant in the valley, from 7000 to 8000 feet; as is an ivy, very like the English, but with fewer and smaller yellow or reddish berries; and many other plants,[[150]] not found at equal elevations on the outer ranges of the Himalaya.
[149] Also called A. Khutrow and Morinda. I had not before seen this tree in the Himalaya: it is a spruce fir, much resembling the Norway spruce in general appearance, but with longer pendulous branches. The wood is white, and considered indifferent, though readily cleft into planks; it is called “Seh.”
[150] Wood-sorrel, a white-stemmed bramble, birch, some maples, nut gigantic lily (Lilium giganteum), Euphorbia, Pedicularis, Spiræa, Philadelphus, Deutzia, Indigofera, and various other South Europe and North American genera.
Chateng, a spur from the lofty peak of Tukcham,[[151]] 19,472 feet high, rises 1000 feet above the west bank of the river; and where crossed, commands one of the finest alpine views in Sikkim. It was grassy, strewed with huge boulders of gneiss, and adorned with clumps of park-like pines: on the summit was a small pool, beautifully fringed with bushy trees of white rose, a white-blossomed apple, a Pyrus like Aria, another like mountain-ash, scarlet rhododendrons (arboreum and barbatum), holly, maples, and Goughia,[[152]] a curious evergreen laurel-like tree: there were also Daphnes, purple magnolia, and a pink sweet-blossomed Sphærostema. Many English water-plants[[153]] grew in the water, but I found no shells; tadpoles, however, swarmed, which later in the season become large frogs. The “painted-lady” butterfly (Cynthia Cardui), and a pretty “blue” were flitting over the flowers, together with some great tropical kinds, that wander so far up these valleys, accompanying Marlea, the only subtropical tree that ascends to 8,500 feet in the interior of Sikkim.
[151] “Tuk” signifies head in Lepcha, and “cheam” or “chaum,” I believe, has reference to the snow. The height of Tukcham has been re-calculated by Capt. R. Strachey, with angles taken by myself, at Dorjiling and Jillapahar, and is approximate only.
[152] This fine plant was named (Wight, “Ic. Plant.”) in honour of Capt. Gough, son of the late commander-in-chief, and an officer to whom the botany of the peninsula of India is greatly indebted. It is a large and handsome evergreen, very similar in foliage to a fine rhododendron, and would prove an invaluable ornament on our lawns, if its hardier varieties were introduced into this country.
[153] Sparganium, Typha, Potamogeton, Callitriche, Utricularia, sedges and rushes.
The river runs close tinder the eastern side of the valley, which slopes so steeply as to appear for many miles almost a continuous landslip, 2000 feet high.
Lamteng village, where I arrived on the 27th of May, is quite concealed by a moraine to the south, which, with a parallel ridge on the north, forms a beautiful bay in the mountains, 8,900 feet above the sea, and 1000 above the Lachen. The village stands on a grassy and bushy flat, around which the pine-clad mountains rise steeply to the snowy peaks and black cliffs which tower above. It contains about forty houses, forming the winter-quarters of the inhabitants of the valley, who, in summer, move with their flocks and herds to the alpine pastures of the Tibet frontier. The dwellings are like those described at Wallanchoon, but the elevation being lower, and the situation more sheltered, they are more scattered; whilst on account of the dampness of the climate, they are raised higher from the ground, and the shingles with which they are tiled (made of Abies Webbiana) decay in two or three years. Many are painted lilac, with the gables in diamonds of red, black, and white: the roofs are either of wood, or of the bark of Abies Brunoniana, held down by large stones: within they are airy and comfortable. They are surrounded by a little cultivation of buck-wheat, radishes, turnips, and mustard. The inhabitants, though paying rent to the Sikkim Rajah, consider themselves as Tibetans, and are so in language, dress, features, and origin: they seldom descend to Choongtam, but yearly travel to the Tibetan towns of Jigatzi, Kambajong, Giantchi, and even to Lhassa, having always commercial and pastoral transactions with the Tibetans, whose flocks are pastured on the Sikkim mountains during summer, and who trade with the plains of India through the medium of these villagers.
