After about five miles of what, in the Himalaya, may be called tolerably level road, another sudden ascent follows, the road inclining rather to the northern slope of the mountain, and entering a dense forest of large massive pines, intermixed with two species of sycamore, and a fine cherry, which relieve the otherwise too gloomy foliage of the coniferous trees. A magnificent climbing vine, which attaches itself to the tallest trees, rising in light green coils round their trunks, and falling in graceful festoons from the branches high over head, adds much to the elegance of the scene, and renders it, in the expressive words of Griffith, who was familiar with the rich vegetation of the humid forests of the Eastern Himalaya, the only true Himalayan forest of the western mountains.
SUMMIT OF MAHASU.
August, 1847.
On this ascent the road rises to about 9000 feet, the crest of the Mahasu ridge being, according to Captain Herbert, 9200 feet. The large size and dense shade of the trees, and the abundance of Abies Smithiana, of the sycamore, and of the gigantic vine, give the forest a totally different appearance from that of Simla, and the undergrowth presents also a considerable amount of novelty; a species of currant, a fine Spiræa, Indigofera atropurpurea, and fine species of Rosa and Rubus, forming thickets under the tall trees. This forest, indeed, from its dense shade, and great humidity, exhibits a much greater contrast to the ordinary temperate vegetation of the Himalaya, than is usually observed below 9000 feet, at which elevation the upper temperate, or subalpine vegetation, begins fairly to predominate over that which is prevalent from 5000 to 9000 feet.
On reaching the summit of the steep ascent, the road again gains the crest of the ridge, which consists of a succession of rounded knolls, covered with grass, and quite bare of trees, the forest rising almost, but not quite, to the top. On the very summit of one of the first of these knolls, is a small wooden shrine or temple, of a form common in the hills; the top of a mountain, or the summit of any very steep ascent, being usually selected as a proper spot for the erection of a sacred building by Indian mountaineers, in whose superstition every hill and grove is tenanted by supernatural beings.
POTATO CULTIVATION.
August, 1847.
The steep ascent on the northern shoulder of Mahasu, from 8000 feet, and even lower, to above 9000 feet, is the great seat of the potato cultivation in the neighbourhood of Simla. The steepest slopes seem to be preferred for this purpose, if they have only a sufficiency of soil, which is very light, loose, and stony. The undergrowth of shrubs is cleared away entirely on the spot where potatoes are planted, but the pine forest is only partially thinned, the tall straight trunks allowing of a free circulation of air below, while the thick branches above afford the amount of shade requisite for the crop. The potatoes are planted in rows in May; and, early in June, when the plants have attained a height of a few inches, the soil is earthed up round their stems in low ridges. The rains commence in the latter part of June, and during their continuance nothing is done to the crop, beyond keeping it clear of weeds. The steepness of the slope seems to afford a sufficient drainage to prevent any injury from the great rain-fall and constant humidity. The growth of the plants is exceedingly luxuriant, the foliage being tall and bushy. By the middle of October, or after the close of the rains, the potatoes are dug and ready for market, supplying not only the station of Simla, but being despatched in great quantities to the plains of India, where the potato is only cultivated as a winter crop, and where, therefore, during the cold months, none are otherwise procurable.
On the very summit of the Mahasu ridge, there are a few trees of Quercus semicarpifolia, the alpine oak of the western Himalaya, an European-looking and partially deciduous species, and of Picea Webbiana, or Pindrow, the silver fir of the Indian mountains, a dark sombre-looking pine, abundant in the forests of the interior. These trees may be adopted as the characteristics of the subalpine zone, in every part of which, from 9000 to about 12,000 feet, which is the highest limit of tree vegetation in the Western Himalaya, they abound. On Mahasu they are entirely confined to the crest of the ridge, and form no part of the forest below.
FAGU.
August, 1847.
The descent from the top of Mahasu to the Fagu bungalow, is at first abrupt, the road leaving the ridge to enter the forest on the northern face, and winding down, after a few hundred yards of bare stony slope, among dense forest, among which it continues for a couple of miles, rising at last rather steeply to the crest of the ridge at the point where it resumes a northerly direction. Here the bungalow of Fagu has been built, at an elevation of 8200 feet, at the very base of the steep mountain ridge behind, which rises abruptly, to a height of six or seven hundred feet. The bungalow faces the north-east, and commands a most superb view of the snowy range beyond the Sutlej, with occasional glimpses of the Jumno-Gangetic snows on the right hand.
On my arrival at Fagu, in the midst of a pelting fall of rain, I found the bungalow already occupied by my fellow-travellers, and before a bright and comfortable fire I soon forgot the discomfort of my wet ride, which indeed was not to be complained of, as it was only what might fairly have been expected in the middle of the rainy season. The confusion among our baggage, however, was so great, from its arriving irregularly and being set down hurriedly by the drenched porters, anxious to escape as soon as possible to shelter, that it was not without difficulty I procured the necessary change of clothing.
