A very favourite and interesting excursion from Dorjiling is to the cane bridge over the Great Rungeet river, 6000 feet below the station. To this an excellent road has been cut, by which the whole descent of six miles, as the crow flies, is easily performed on pony-back; the road distance being only eleven miles. The scenery is, of course, of a totally different description from that of Sinchul, or even of the foot of the hills, being that of a deep mountain-valley. I several times made this trip; on the excursion about to be described, and in which I was accompanied by Mr. Barnes, I followed the Great Rungeet to the Teesta, into which it flows.
In descending from Dorjiling, the zones of vegetation are well marked between 6000 and 7000 feet by—1. The oak, chesnut, and Magnolias, the main features from 7000 to 10,000 feet.—2. Immediately below 6,500 feet, the tree-fern appears (_Alsophila gigantea,_ Wall.), a widely-distributed plant, common to the Himalaya, from Nepal eastward to the Malayan peninsula, Java, and Ceylon.—3. Of palms, a species of _Calamus,_ and _Plectocomia,_ the “Rhenoul” of the Lepchas. The latter, though not a very large plant, climbs lofty trees, and extends about 40 yards through the forest; 6,500 feet is the upper limit of palms in the Sikkim Himalaya, the Rhenoul alone attaining this elevation.[46]—4. The fourth striking feature is a wild plantain, which ascends to nearly the same elevation (“Lukhlo,” Lepcha). This is replaced by another, and rather larger species, at lower elevations; both ripen austere and small fruits, which are full of seeds, and quite uneatable; that commonly grown in Sikkim is an introduced stock (nor have the wild species ever been cultivated); it is very large, but poor in flavour, and does not bear seeds. The zones of these conspicuous plants are very clearly defined, and especially if the traveller, standing on one of the innumerable spurs which project from the Dorjiling ridge, cast his eyes up the gorges of green on either hand.
