In the month of May, 1847, while with my Regiment at Firozpur on the south bank of the Sutlej, I received intimation that Lord Hardinge, at that time Governor-General of India, had appointed me a member of a mission which he had determined to despatch across the Himalaya Mountains into Tibet; and I was directed to proceed without delay to Simla, from which place the mission was to start, as soon as the necessary arrangements could be completed.

I left Firozpur on the evening of the 20th of May, and travelling only at night, on account of the extreme heat, I arrived at the foot of the hills, on the morning of the 24th. The greater part of the road was through a perfectly level country, and nearly parallel to the Sutlej, but without following its sinuosities. During a part of the last night's journey, I travelled among low hills, partly composed of loose sand and boulders, partly of clay and sandstone. The road enters this tract by an open valley, bounded on both sides by hills, which on the left are low and rounded. On the right they are scarped towards the plains, as well as towards the valley up which I travelled, and the strata of which they are composed, dip towards the Himalaya. The valley is traversed by a little stream descending from the mountains, one of the tributaries of the Gagar or Markanda, that remarkable river, which runs in a south-west direction, as if about to join the Indus, but ultimately loses itself in the sands of the Bikanir desert.

APPEARANCE OF HIMALAYA FROM THE PLAINS OF INDIA.

May, 1847.

When viewed from the plains of India, at a distance sufficient to enable the spectator to see the most elevated part of the chain, the Himalaya appear to form several distinct parallel ranges on the horizon, rising in succession one behind another. The most distant of these is covered with perpetual snow, while the other two, usually called the middle and outer ranges, have the usual blue-grey tint of distant mountains. From very great distances in the plains, the most remote of these three apparent ranges is alone visible; and as the traveller advances towards the base of the mountains, the others rise in succession above the horizon.

The optical deception, in consequence of which, masses of mountains of every configuration resolve themselves into ranges perpendicular to the line of sight, as soon as the eye is so far removed that the outline of the different parts becomes indistinct, has given to our maps many mountain-chains, which a nearer inspection proves to have no existence. As a good instance of this, I may mention the Suliman range, west of the Indus, which, though laid down in all our maps as a mountain belt, parallel to and skirting the plain country, behind which no mountains at all are represented, evidently consists of a series of ranges, almost perpendicular to the Indus, and separated from one another by considerable rivers. The sources of these rivers lie far back, and the north and south axis from which they spring, separates all the tributaries of the Indus from a succession of streams, which run in a south-westerly direction, and appear to terminate, without reaching the sea, in the low and flat country of Seistan and western Beluchistan.

At distances of between sixty and thirty miles from the base of the Himalaya, the three parallel chains are well seen. On a nearer approach, the lower and outer mountains by degrees become more distinct, and subtend a greater angle, so as at last to conceal the more distant portions of the chain. At the same time, the uniformity of outline by which they had been characterized, insensibly disappears. Ridges become visible in the face presented to the eye, which, as the traveller continues to advance, become developed into projecting spurs, separated from the general mass by wide valleys, previously quite undistinguishable. On a still nearer approach, the elevation continuing to increase, the extent of range embraced by the eye is gradually lessened, till at last, when we arrive at the base of the mountains, a single valley with its bounding ranges of low hills is alone visible, the giant masses, so conspicuous from a greater distance, being no longer to be seen.

The low sandy or sandstone hills, which form the outskirts of the Himalaya, are not, on the road from Firozpur to Simla, anywhere of greater elevation than a few hundred feet. A few miles beyond the entrance, the valley, which has a considerable slope, widens as it approaches the more lofty mountains, and the sandstone cliffs are replaced by rounded hills, probably of a more ancient rock, covered with soil and vegetation.

KALKA.

May, 1847.

At the very base of the steep mountains is situated the village of Kalka, at which, as it is the termination of palankin travelling, travellers in general stop, to arrange for the continuance of their journey. Situated close to the source of the little stream which I had been following since I had entered the hilly country, and surrounded on all sides by low hills, Kalka has an elevation of perhaps 2000 feet above the level of the sea, or 1000 feet above the plain on the outside of the sandstone hills.

The general aspect of the low hills around Kalka is barren and uninviting; it was especially so at the season of my visit, when the great heat had scorched the herbaceous vegetation, and all nature had a burnt-up appearance. The subtropical valleys are not here, as farther to the east along the base of the mountains, filled with dense forest. They are in general bare, a few scattered trees only appearing here and there. In the level part of the valley, at the very entrance, where the soil was still of some depth, Acacia Arabica and Butea frondosa, the most prevailing trees of the plains beyond, were frequent; but the stony water-courses contained little but a bamboo, and the hill-sides were covered with scattered bushes of the more ordinary shrubs of the plains of Northern India, and presented few features of interest.

ASCENT TO KUSSOWLEE.

May, 1847.

Immediately on leaving Kalka, a long and steep ascent commenced, continuing for about ten miles, to the military post of Kussowlee, which occupies the crest of the ridge overlooking the Kalka valley, and can be seen throughout the greater part of the ascent, overhanging the winding road, which has been constructed along the side of the mountain. The elevation of Kussowlee is about 6500 feet, an altitude at which the climate in the Himalaya is perfectly temperate, so that during the ascent a traveller from the plains of India meets with a complete change of climate, a change, too, which in the month of May, the period of my visit, is particularly grateful, the heat below being most oppressive and disagreeable.

As the elevation increases, the view from the road becomes more extensive. The low ranges of hills to the south and west, which had obstructed the view, are by degrees overtopped, and the plains beyond become visible. Soon after leaving Kalka the road crosses a low ridge, and enters a receding bay, or steeply sloping valley beyond, at the upper extremity of which, all along the crest, are seen the houses of Kussowlee. Winding round this valley, and continuing to rise, the stream in its centre is crossed about midway, and the ascent continues on the spur which forms its western boundary. This ridge is crossed close to the point where it is given off by the main range, and the road, winding round its most projecting part, enters a fir-wood, and, turning back very abruptly in an opposite direction, proceeds eastward along the northern face of the Kussowlee range.

VEGETATION.

May, 1847.

The plainward face of this range, along which the road from Kalka ascends, is quite devoid of forest. The lower part is covered with scattered jungle, to use a most expressive Indian word, of small shrubs, almost all of forms common in the plains. Carissa and Adhatoda are the most common, with Rottlera tinctoria, a plant which does not extend far into the plains, and a scandent leguminous shrub, apparently a species of Mucuna. Around the few houses which occur on the ascent, the bamboo occurs planted, as well as the mango, and other common cultivated trees of the Indian plains. At an elevation of about 4000 feet, an alteration in the vegetation begins to be perceptible. The thin jungle of plain shrubs disappears, the few shrubs which still occur, are generally scattered bushes of Hamiltonia, Nyctanthes, Prinsepia, Scutellaria, and Rubus, but the slopes are usually bare and grassy. Ferns and mosses appear in the crevices of the rocks, and the first individuals of those species which predominate in the temperate zone, are found in shady spots where they are sheltered from the sun. At the same elevation Euphorbia pentagona makes its appearance. This tree, which is confined to the hottest and driest slopes of the Himalaya, is remarkable for its peculiar shape, its thick fleshy five-angled branches, and its milky juice. It is nowhere to be met with in the plains of Upper India, but is common throughout the subtropical belt of the Himalaya from Kamaon westward.

ORIGIN OF KUSSOWLEE RIDGE.

May, 1847.

A glance at the map will serve to show that the great Himalayan mountain range, dividing the waters of the Sutlej from those of the Jumna, holds a nearly due east and west course in its middle part, but that at its western extremity it bends round to the south, and terminates in the Indian plain, not far from the town of Nahan, and that (among many others) the Kussowlee ridge is a branch from it, running in a north-westerly direction, and separating the waters of the more western branch of the Gambar, from the small tributaries of the Gagar, which find their way to the plains on the left hand.

The ridge upon which the station of Kussowlee is built, nowhere attains an elevation exceeding 7000 feet. It is very narrow, and often rocky and precipitous immediately below the crest on the plainward face, which dips very suddenly. The inner slope is somewhat less abrupt, and is covered from the summit to perhaps 1000 feet below it, with an open forest of a species of fir (Pinus longifolia), which, in general appearance and mode of growth, much resembles the Scotch fir, but is distinguished by the very great length of its leaves. The barracks for the troops and the houses of the residents are scattered over the northern slope, or perched on the narrow summit of the ridge.

The shrubby and herbaceous vegetation which occurs scattered among the fir-wood, is so markedly different from that which prevails at the base of the mountains, and during the greater part of the ascent, that the traveller appears suddenly transported into a new world. Instead of those tribes of the vegetable kingdom which abound in the torrid zone, all the forms which now meet the eye are characteristic of a temperate climate. The moderate elevation of the range, and its proximity to the plains, tend to lessen the rapidity of the diminution of temperature; and as the greater part of the ascent lies on a bare sunny slope, the tropical flora extends towards the summit, much farther than it does on ranges which rise higher, and are clothed with shady forest. During the ascent, therefore, the traveller, though often struck with the appearance of new forms, is still accompanied by many species familiar to him as natives of tropical jungles, but on passing to the northern face of the spur, the temperate region is at once entered, and most of the tropical forms disappear.

VIEW FROM KUSSOWLEE.

May, 1847.

As soon as the crest of the first slope of the Himalaya has been gained, the eye is naturally directed towards the mountains beyond, in order to ascertain their appearance and position, when viewed at a diminished distance and from so much more considerable an elevation than had previously been the case. Nor will the view from Kussowlee in favourable weather disappoint the traveller who is desirous of meeting with beautiful scenery. Immediately to the north lies a deep ravine, and beyond a single ridge is the wide valley of the Gambar, with numerous mountain spurs, which, from their comparatively lower level, are not prominently brought into view. To the south-east the main range dips abruptly to a level, nearly 1000 feet below what it attains in the station of Kussowlee itself, but again rises into the finely wooded hill on which has recently been built the Lawrence Asylum. Still further to the south are deep dells, with bare and rugged slaty mountains, scarcely at all wooded. In the months of May and June, when the atmosphere is generally extremely hazy, the prospect is limited to the ranges more immediately in the vicinity; but occasionally even in these months, as well as in the dry intervals of the rainy season, and during the delightful autumn weather which follows the termination of the rains, a much more distant prospect is opened, stretching far up the valley of the Sutlej, to the snow-clad peaks which, on either hand, hem in that river.

In the direction of the plains of India, the view is also very remarkable. The Kussowlee ridge so completely overtops the hills which intervene between it and the level country, that from its summit they interfere very little with the commanding view of the interminable flat which, like the ocean, stretches as far as vision extends. In the usual state of the atmosphere, especially in the hot season, a dense haze overhangs the plains, and entirely obscures their more distant parts; but in the cold season, as well as at day-break in summer, and especially after heavy rains, the misty vapours are entirely dissipated, and distant objects are defined with extreme precision.

Perhaps the most striking, because the most unexpected part of the view of the inner Himalaya, from Kussowlee, lies in the great depth of the valleys in the interior, and the distance of the next elevated range, of which the appearance of the mountains from the plains of India affords no indication. The extreme narrowness of the ridge, and the suddenness of the descent on both sides, is also very remarkable, and has, as already remarked, a very sensible effect on the climate, the heat of the lower mass being conveyed upwards, while the small extent of the knife-edge-like ridge, which rises above 6000 feet, exposes a minimum surface to the refrigerating influences of a rarefied atmosphere.

ROAD TO SIMLA.

May, 1847.

The distance from Kussowlee to Simla is by the road about thirty miles, though in a direct line the two places are not much more than half that distance apart. The road descends from Kussowlee almost to the level of the plains, crossing the Gambar at an elevation of a little less than 3000 feet, and ascends to Simla by following the ridge which runs parallel to that river on its right bank, the source of the Gambar being immediately below Simla. It would indeed be possible to reach Simla, by following the crest of the ridge, without descending at all into the valley of the river; but for this purpose it would be necessary to follow the Kussowlee ridge so far to the southward, in order to reach its junction with the main range, that the length of the journey would be very much greater than that now followed. The road, therefore, only keeps the ridge for a very short distance, or as far as the "col," or lower part immediately north of Kussowlee, which is quite bare of trees. It then turns abruptly to the left, descending on the north face of a spur, at first in a winding manner, afterwards for a short distance along a shady ravine, and finally through a good deal of cultivation, at an elevation of between 4000 and 5000 feet, to a considerable stream which runs towards the north to join the Gambar. The greatest part of the descent is bare of trees, except along the banks of the little stream, which are covered with a belt of wood. The cultivated lands are extensive, occupying a flattish terraced slope, such as is of very general occurrence in the mountains, the fields being adapted for the growth of rain crops, principally of rice, with a few fields of ginger and cardamoms.

SABATHU.

May, 1847.

After reaching the stream just mentioned, which is crossed by a ford, a suspension bridge, for which the piers are partly built, having never been erected, the road continues to descend parallel to it towards the north, passing under the military station of Sabathu, which, at the elevation of 4200 feet, occupies the crest of the ridge immediately to the east of the little river, a very short distance before its junction with the Gambar.

After passing Sabathu the road turns to the right, round the projecting ridge of the range, and descends rapidly to the valley of the Gambar river, which is crossed by a good suspension bridge at an elevation of 2700 feet above the level of the sea. It then ascends by a steep and laborious path to Haripur, a small village about 500 feet above the bed of the river. The Gambar river, where the road crosses it, flows through a narrow rocky ravine, somewhat picturesque, but quite devoid of trees. This, however, is not the general character of the river-bed, which is frequently wide, with a broad gravelly channel, and sloping though often rather steep mountains on either side. There is occasionally even a strip of flat land, capable of cultivation along the banks; and where such is the case, the water of the river is carried off in artificial channels, for the purpose of irrigation.

After attaining the crest of the ridge, and passing through the village of Haripur, the road follows the ridge parallel to the river Gambar, nearly all the way to Simla, not always on the very crest or top, which would entail a great many unnecessary ascents and descents, but generally a little on one side or other of the hill, as circumstances may render most convenient; at one time ascending rather steeply, but more generally rather gently as far as Sairi, the last stage on the way to Simla, beyond which the road is pretty level, nearly to the bottom of the mountain on which Simla stands.

The valley of the river Gambar may be regarded as an excellent specimen of a smaller Himalayan river, draining a large extent of country, and discharging its waters independently into the plains, though not, like the first-class rivers, deriving its origin from the snowy mountains. The southern border of the basin of the Gambar, is of course the main chain of the South Sutlej Himalaya; and the whole of the country between the Jutog spur, which leaves that chain at Simla, and the Kussowlee ridge, the origin of which I have already detailed, is drained by the Gambar and its tributaries. This includes an extent of country of not less than 1000 square miles, the bounding ranges of which have, throughout the greater part of their extent, an elevation varying from 8000 to about 6000 feet. Both the Kussowlee and Jutog ranges dip at last rather abruptly, so that it is only during a very short distance that they are below the last-mentioned elevation. This elevation, which is quite temperate, is however by no means that of the whole superficies of the basin, the bed of the river having, at its débouchure into the Sutlej, an elevation of not more than 2000 feet, and rising very gently till near its source immediately below Simla. The lateral ridges, which traverse the basin in every direction, are in general less elevated; not exceeding 5000 feet in their upper part, and sinking to 3000 or even lower, so that the mean elevation of the whole basin cannot be estimated, I should think, higher than 3500 feet.

BASIN OF GAMBAR VEGETATION.

May, 1847.

Such being the case, it is not surprising that the general appearance of the vegetation should be tropical, and closely approximate to that of the low hills on the very exterior of the Himalaya. This is in general the case. The hills, which are generally grassy, and, though steep and frequently stony, rarely rocky or precipitous, are quite devoid of forest, or even brushwood, except in a few shady nooks with a northern exposure, and favourably situated with respect to moisture; the shrubby vegetation being thin and scattered. This total want of forest, is unquestionably caused by the dryness of the climate during the greater part of the year, which is to a certain degree increased beyond what it would otherwise be, by the proximity of the surrounding mountain ranges, to which a large proportion of the rain-clouds are no doubt attracted.

In the shady ravines north of Kussowlee, where there is the greatest approach to forest, a species of laurel is the most conspicuous tree. On the more exposed hills, Falconeria insignis and Euphorbia pentagona occur, scattered as small trees, and one small wood of ?gle marmelos is passed close to the village of Haripur. The most common shrubs are Adhatoda Vasica, Carissa, and Zizyphus Jujuba, species universal in the plains of upper India; Colebrookea oppositifolia, Grislea, Bergera, Roylea and B?hmeria nivea, all species which are throughout the north-west Himalaya, characteristic of the lower and drier parts of the outer ranges. Two Labiate shrubs, Plectranthus rugosus and Meriandra strobilifera, are particularly abundant on the slopes between Haripur and Sairi, and strongly mark the aridity of the climate.

The herbaceous vegetation, being principally of annual growth, approaches still more closely to the plains types. At the season of my journey in May, the extreme drought had dried up almost all the smaller plants, but during, and immediately after the rainy season the herbage is very luxuriant. The steep slopes are then covered with a uniform herbage of tall grasses, which is in many places cut and preserved for hay, by the inhabitants of the scattered villages in the valleys. The most prevailing grasses are a tall sweet-scented Cymbopogon and Heteropogon contortus. A species of Kalancho?, a large and conspicuous plant, with thick fleshy leaves, is very common, and the superb Gloriosa or Methonica is by no means rare.

On the highest ridges in the valley, at elevations of 5000 feet and upwards, there are frequent approaches to the temperate flora, the shady slopes on northern exposures being frequently covered with small patches of brushwood, containing species of Berberis, Rubus, Spir?a, etc., and numerous herbaceous species, of forms common at Simla. These, however, are quite exceptional, though no doubt with a very little more humidity the shrubby vegetation would rapidly extend, and under its shelter many small plants would be able to grow, which are now, when they attempt to vegetate, destroyed by the scorching heat of the sun.

It must also not be forgotten, that notwithstanding the general tendency to a tropical flora, the natural result of the low elevation and great aridity of these hills, a portion of the vegetation even at the lowest levels consists of plants of European forms, such as characterize the temperate vegetation of the Himalaya. I do not here refer to what may be called the cold-weather vegetation of the plains of north-western India, at which season, the temperature of the air approaching to that of the summer of the temperate zone, a considerable number of European plants make their appearance in corn-fields and along the banks of water-courses; as, for example, Veronica Anagallis and agrestis, Anagallis, Medicago, Melilotus, Potentilla supina, Juncus bufonius, Arenaria serpyllifolia, Heliotropium Europ?um, and many others. These naturally occur at the same season, in the low valleys among the hills, in similar situations. The circumstance to which I desire to advert, is the occurrence at very low levels among the mountains, during the hot and rainy seasons, of species belonging to genera characteristic of temperate climates, and which therefore are the prevailing forms at considerable elevations on the Himalaya. As instances, I may adduce the occurrence in the valley of the Gambar, at elevations not exceeding 3000 feet, of species of Thalictrum, Fragaria, Rosa, Rubus, Berberis, &c., &c. This remarkable fact has been ascribed by Jacquemont[1] to the obscure influence of the mountains; and as the genera just enumerated never occur in the plains of Upper India, it appears evident that the mountainous nature of the country must be viewed as an essential element in the reasons for their descent. These, with some others which also occur at low levels in the Himalaya, appear to be in all parts of the continent of India those genera of temperate climates, which descend to the lowest altitudes. Some of them were found by Dr. Hooker on Parasnath, a hill in upper Behar, the elevation of which does not exceed 4000 feet; and they are all natives of moderate elevations on the Nilgherries and in Ceylon, as well as on the Khasya mountains in eastern Bengal.

ASCENT TO SIMLA.

May, 1847.

SIMLA.

May, 1847.

The ridge which runs from Haripur to Sairi, parallel to the river Gambar, is a branch from the Jutog spur, nearly north of Simla, a ridge which is given off by the main South Sutlej chain in Simla itself, and which runs directly north to the Sutlej river. The road, after following this ridge till within a few miles of Simla, leaves it on the left hand, to descend into a small stony ravine; after crossing which it mounts abruptly a very steep spur, ascending at least 1500 feet to gain the crest of the ridge, and enter Simla at its north-western extremity.

The hill station of Simla, which was originally selected as a sanatarium, or suitable residence for the servants of Government, or other Europeans, whose health had been impaired by disease, or by too long residence in a tropical climate, has of late years, in consequence of the political state of north-western India, and of the increasing number of retired officers, and of gentlemen unconnected with the public service, who have made it their residence, become a place of great importance. Besides an extensive bazaar or collection of shops, which may now almost be designated a small native town, Simla contains nearly 400 houses, scattered along the crest of different mountain ranges. Its situation is a most favourable one, on the main range of mountains south of the Sutlej river, at a point where a massive peak rises to a height of 8100 feet, and on the nearest part of the ridge to the plains of India, which is sufficiently elevated, well wooded, and situated favourably with regard to water. The greater part of the station is built on the main range, partly surrounding the peak of Jako, and partly on the ridge running north from it, at an elevation of about 7000 feet, as far as a smaller culminating point of the range, which is by the inhabitants named Prospect Point. At this point the main range turns sharply to the west, and the station is continued for nearly a mile on a spur which runs towards the north, passing through the station of Jutog. From the scattered position of the houses, the extent of Simla is much more considerable than the bare statement of the number of houses might lead one to suppose. The northern ridge extends almost four miles, and the circuit of Jako, by the principal road, which is from 500 to 1000 feet below the summit, measures five miles.

In consequence of the sudden elevation of the mountain range at the place where Simla has been built, there is a most complete and surprising change in the vegetation and general appearance of the scenery. During the last ascent on the road from the plains this is sufficiently perceptible, although from the great ravages which the proximity of so large a population has made in the oak woods, only a few stunted bushes are now left on the southern exposure. Between the plains and Simla the hills are totally devoid of trees, but immediately on gaining the top of the ridge on which the station is built, we enter a fine forest, which covers all the broader parts of the range, especially the slopes which have a northern aspect, stretching down on these in many places to the bottom of the valleys, fully 2000 feet.

OAK FOREST.

May, 1847.

PINES OF SIMLA.

May, 1847.

The nature of the forest varies a good deal with the exposure and with the quality of the soil. By far the greater part consists of an oak and a rhododendron, both small evergreen trees, rarely exceeding thirty or forty feet, with wide-spreading arms and rugged twisted branches. A species of Andromeda is also very common, and a holly, an Euonymus, Rhamnus, and Benthamia, are the other more common trees, if we except the Conifer?, of which four species occur. Of these, Pinus longifolia is common at the western or lower extremity of the station, and prevails, to the exclusion of any other tree, on the dry sunny spurs which run towards the south, at elevations from 7000 to 5000 feet. This species is, of all the Indian pines known to me (except its near ally P. Khasyana), that which is capable of enduring the most heat, and at the same time the greatest variation in amount of moisture; as it is found at elevations of not more than 1000 feet above the level of the sea, equally in the hot humid valleys of Sikkim, where it enjoys a perpetual vapour-bath, and on the dry sandstone hills of the upper Punjab, on which rain hardly ever falls. It is only, however, at low elevations, where the mean temperature is high, that it is capable of supporting a great amount of humidity, for in the damp climates of the Himalaya it is entirely wanting, except in the deepest valleys; and even in the drier districts it is always observed to select the sunnier, and therefore warmer exposures. Its upper limit is usually about 7000 feet above the level of the sea, though on Jako at Simla a few stunted trees rise as high as 7700 feet.

Pinus excelsa is also a very common species at Simla, particularly on the southern face of Mount Jako, which is the highest part of the ridge. Abies Smithiana, the third coniferous tree, is exceedingly rare, a few trees only occurring in a shady ravine facing the west; while the deodar, the fourth species, is common on the southern and western slopes of Jako, above 7000 feet; and again in shady groves at the bottom of the valleys on both sides of the ridge, as low as 5000 feet. This beautiful tree, the cedar of the Indian mountains, seems limited to the western half of the Himalayan range, extending from the most westerly part of Nipal, as far as the mountains of Affghanistan. It was first described by Roxburgh from specimens sent to him from Kamaon, at a time when the western Himalaya was almost inaccessible to Europeans, under the name by which it is known to the inhabitants of that province, as well as in Kashmir. It is, however, singularly enough, not known by that name in the Simla hills, where it is called Kélu; another conifer, Cupressus torulosa, a rare tree in the district, having usurped the name, as well as the sacred character, of deodar.

In the thick woods of Simla, a large white monkey, the Langúr of the natives, is very common. These animals move about in large flocks, in which may be seen individuals of all sizes and ages, and seldom remain more than a few hours in one place. They are in constant motion, leaping from bough to bough and from tree to tree, chattering constantly; and, notwithstanding their great size, are in general harmless, though ready enough to defend themselves if assailed.

The forest extends in parts close up to the peak of Jako, which has an elevation of 8130 feet. The very summit, however, which is a short flat ridge, and a considerable part of the east and south face, are bare and grassy, or covered with scattered shrubs. The more common shrubby forms of the vegetation of the temperate zone, are Salix, Rosa, Rubus, Lonicera, Viburnum, Berberis, Indigofera, and Prinsepia, all, except the two last, quite European. Indigofera forms a remarkable exception, and one well worthy of note, as the genus is a very tropical one, although its shrubby species are particularly abundant throughout the whole of the western Himalaya. These shrubby species, however, constitute a particular section of the genus, very distinct in habit, and in the large size and bright colour of the flower, from the more ordinary forms, and they are confined to the drier parts of the mountains, being quite wanting in the humid climate of Darjeeling and Khasya, and almost entirely so in the mountains of the Peninsula.

VEGETATION OF THE SPRING MONTHS.

May, 1847.

The herbaceous vegetation of the spring months quite corresponds, in the temperate nature of its forms, with what has been found to be the case with the trees and shrubs; but during the rainy season, as has been well pointed out by Dr. Royle in his valuable essay on the distribution of Himalayan plants, this is much less markedly the case. At the commencement of spring, in April (for March is still too cold for much vegetation), the weather being generally bright, though with occasional heavy showers, the earliest flowers are species of Viola, Fragaria, Geranium, Veronica, Valeriana, and dandelion. From April, as summer advances, the temperature gradually rises, till towards the end of June, when the rainy season commences. These months are generally dry, and if no rain falls the heat is sometimes considerable, the thermometer rising as high as 80° in the shade. Still the flora is almost entirely temperate, the early spring plants being succeeded by many others of European families, principally Ranunculace?, Rosace?, Labiat?, Stellat?, Polygonace?, Epilobiace?, Primulace?, etc. I can scarcely enumerate a single spring flowering plant which does not belong to an European family, unless Arum be an exception, which it can hardly be considered, the flowers only being displayed during May and June, while the leaves do not make their appearance until after the rainy season has commenced. Few species are, however, identical with those of Europe, except Stellaria media, Cerastium vulgatum, Taraxacum officinale, Verbascum Thapsus, Thymus Serpyllum, and Poa annua.

FLORA OF RAINY SEASON.

July, 1847.

PEAK OF JAKO.

July, 1847.

The rainy season generally commences about the 20th of June, or between that date and the end of the month, and continues till the middle or end of September, with occasional intermissions, rarely exceeding a week at a time. During the rains the atmosphere is exceedingly moist, dense fogs usually prevailing when rain does not fall. The rain-fall is probably more considerable at Simla than in the lower ranges, which are nearer the plains, for it has been observed that ranges of 7-8000 feet (which are generally for this reason well wooded), attract much moisture, and the peak of Jako and other parts of Simla are frequently observed from the stations of Sabathu and Kussowlee, to be covered with dense clouds or mist, at times when at the latter places the weather is bright and clear.

The commencement of the rainy season is the signal in the mountains, as it is very universally throughout India, wherever that season is well marked, for the appearance of a very vigorous and luxuriant growth of plants of annual growth, the seeds (or rootstocks) of which had been lying dormant in the soil awaiting the access of heavy rain. At Simla, as elsewhere in the temperate region of the Himalaya, we find at this season numerous species of Balsams, Acanthace?, Orchide?, and Labiat?, several Gentians and Cichorace?, a great many grasses and Cyperace?, and species of Parnassia, Drosera, Pedicularis, Roscoea, Dipsacus, Thalictrum, Urtica, etc., etc. Some of these are quite European genera, while others, as Roscoea, are interesting as belonging to orders whose maxima occur in very humid climates. The Labiat? of the rainy season are mostly species of Plectranthus and Elsholtzia, both quite Indian genera, and very extensively distributed in mountainous districts. Balsams are quite an Indian order, and they seem everywhere, as has already been remarked by Dr. Royle and by Dr. Wight, to abound in humid shady places, either in dense forest or on the stony banks of mountain streams, in the drier districts only during the rainy season, but in more humid countries more or less throughout the year. The Orchide? of Simla are entirely terrestrial, the dryness and cold of the winter months being greater than are compatible with the occurrence of epiphytical species of this natural order, and for the same reason, I presume, Melastomace?, so abundant in the Eastern Himalaya, are quite wanting.

Among the many advantages of situation by which Simla is characterized, one of the most fortunate is its position on a part of the mountain range which lies transversely to the ordinary direction of the chain, so that the view towards the plains of India, as well as up the Sutlej valley, is very much more extensive than would be obtained, had the station been situated in a less favourable position. This advantage is further enhanced by the sudden rise in elevation of the chain, which enables a resident at Simla to overlook in the direction of the plains the continuation of the range which would otherwise obstruct the view. Towards the interior of the mountains, this advantage is not possessed by Simla; for the ridge of Mahasu, which rises 1000 feet higher than the peak of Jako, obscures at least half of the snowy range, the view being limited in that direction to the course of the valley of the Sutlej, and to the mountains north of that river.

VIEW FROM THE PEAK OF JAKO.

July, 1847.

With all these advantages of situation, the view from the peak of Jako is one of the most agreeable and diversified, which occur in any part of the Himalaya; although, from the rather too level top of the mountain, and the intrusion of the forest almost to the very summit, the whole panorama cannot be embraced at once. Immediately under the eye are the numerous spurs and ridges covered with scattered houses, and the deep ravines which terminate the steep slopes below the station; towards the plains, the whole valley of the Gambar is seen, with the stations of Sabathu and Kussowlee, the church and esplanade of the former appearing low down almost within a stone's throw, while the brilliant white of the houses of Kussowlee, more nearly on a level with the eye, sparkle in the sunbeams. The ridge of Kussowlee in one place excludes the view of the plains, but to the right they may be seen stretching away in the distance, and only recognizable at last by the track of the Sutlej river, which, from the very remarkable curve close to its exit from the mountains, may be traced as far as vision can extend, a distance of 116 miles[2]. To the north a valley stretches from Simla as far as the Sutlej river, distant about fifteen miles, so direct that the greater part of it is seen, though the river itself is concealed. East of north a long partially wooded ridge, about four miles distant at its nearest point, running parallel to the valley just mentioned, excludes the view of the nearer part of the Sutlej valley; but the lofty ranges north of that river, covered with dense forest, and backed by masses of brilliant snow, close in the view in that direction. Due east lies the Mahasu ridge, covered on the Simla slopes with a dense forest of deodar; and to the south, across the valley of the Giri, towards which numerous rugged ridges run, is the mountain called the Chor, the highest peak of the range which separates the Giri from the Tons, the crest of which is upwards of 12,000 feet in height.

From the peak of Jako, the serpentine course of the range, which prevails universally throughout the Himalaya, may be well traced, as the eye of the spectator, following the direct course of the ridge, can observe numerous turns in its course, each of which, from the great foreshortening, appears much more abrupt than it really is. At each curve the range rises into a peak, while the intermediate portions are lower and excavated into "cols" or passes. In the concavity of each bend of the range is situated the head of a valley, numerous small spurs dividing the different ravines which unite to form it; while on the convex side, from the high portion of the ridge, is given off a branch of the range, forming a separation between two adjacent valleys, each of which occupies a concavity in the main range of mountain.

On my arrival at Simla on the 25th of May, I found that Major A. Cunningham, of the Bengal Engineers, and Captain Henry Strachey, of the 66th Regiment N.I., were to be my fellow-travellers, the former having been appointed the head of the mission. As Captain Strachey had to travel from Dinapore, it was evident that some time would elapse before he would arrive at Simla, nor was it till the beginning of August that the completion of the necessary preliminaries rendered it possible for us to commence our journey. I took advantage of this delay to make myself as far as possible acquainted with the physical features and vegetation of the surrounding country, though the necessary preparations for the approaching journey occupied a good deal of time, and the commencement of the rainy season rendered travelling difficult, and even out-of-door exercise unpleasant. I have already attempted to convey an idea of the general physical aspect of the scenery, which, after a short residence has made one familiar with the structure of the ridges, appears very simple. Situated on the dividing range, by which the waters of the Giri, a tributary of the Jumna, on the left, are separated from those of the tributaries of the Sutlej on the right, the spectator looks into two of the immense basins into which the Himalaya is divided by transverse ranges running parallel to the great rivers; and after a short time he finds that the chaos of mountains, which at first perplexed the eye and confused the mind, gradually resolves itself into a definite shape, each ridge being capable of being referred to its parent, and that in its turn to a branch of the main chain. From his commanding position he can also see that the main range is generally more elevated than its branches, and that each chain, by a succession of sudden sinkings, diminishes in elevation, each peak being lower than its predecessor. Nowhere in the wide tract of country visible is there the least approach to a system of parallel ridges, such as is indicated by the distant view of these mountains. On the contrary, it is seen that the great ranges are, though very irregularly, perpendicular to the general direction of the mountain mass, and that it is only the shorter spurs which have a general uniformity of direction.

STRUCTURE OF THE MOUNTAIN RANGES.

July, 1847.

Nor could I find in the structure of the mountains around Simla any confirmation of the view entertained by Humboldt of the sudden elevation of the Himalaya out of a vast fissure in the external crust of the earth. However plausible such a view might appear when the Himalaya is contemplated as a whole (on a map), without any portion of its extent being under the eye, I found it, on the spot, quite impossible to conceive in what way, after such a sudden elevation, any power in the least analogous to existing forces could have excavated out of the solid rock those numerous valleys, so various in direction, so rugged in outline, and so vast in dimensions, which now furrow the mountain mass.

On the contrary, the conclusion has been forced upon me that these mountains have emerged extremely gradually from an ocean, of the existence of which, at very various levels, the most evident traces are, I think, discoverable. The present configuration of the surface must, I do not doubt, have been given to it during periods of rest, or of very slow elevation, the action of the sea upon submerged rocks being so very superficial that no denudation takes place at any great depth. During the period of emergence of the Himalaya, from the great length of the present valleys, which extend between parallel ranges far into the interior, the coast must have borne a strong resemblance to that of Norway at the present day, numerous promontories projecting far into the sea, and separated from one another by narrow and deep bays.

GEOLOGY.

The geological structure of the Himalaya between Simla and the plains is not easily discovered by the cursory observer. The general basis of the mountains is clay-slate, occasionally very micaceous, passing into a coarse sandstone, but here and there limestone occurs interstratified. The dip is extremely variable, and the rocks, whatever their age, are evidently highly metamorphosed. The tertiary formations, so well illustrated by Falconer and Cautley, extend all along the base of the mountains, and penetrate in some places far into the valleys, for certain rocks in the neighbourhood of Sabathu have been indicated by Major Vicary, which appear to be of the same age, or perhaps of a still older tertiary epoch.
