''Note: National, provincial and district boundaries have changed considerably since 1908. Typically, old states, ‘divisions’ and districts have been broken into smaller units, and many tahsils upgraded to districts. Some units have since been renamed. Therefore, this article is being posted mainly for its historical value. ''
 
 
 
The system of stupendous mountain ranges, lying
 
along the northern frontiers of the Indian Empire, and containing some
 
of the highest peaks in the world. Literally, the name is equivalent
 
to ' the abode of snow ' (from the Sanskrit hima, ' frost,' and alaya,
 
'dwelling-place'). To the early geographers the mountains were
 
known as Imaus or Himaus and Hemodas ; and there is reason to
 
believe that these names were applied to the western and eastern parts
 
respectively, the sources of the Ganges being taken as the dividing line.
 
' Hemodas ' represents the Sanskrit Himavata (Prakrit He/iiota), mean-
 
ing 'snowy.' The Greeks who accompanied Alexander styled the
 
mountains the Indian Caucasus.
 
 
Modern writers have sometimes included in the system the Muztagh
 
range, and its extension the Karakoram ; but it is now generally agreed
 
that the Indus should be considered the north-western limit. From
 
the great peak of Nanga Parbat in Kashmir, the Himalayas stretch
 
eastward for twenty degrees of longitude, in a curve which has been
 
compared to the blade of a scimitar, the edge facing the plains of
 
India. Barely one-third of this vast range of mountains is known with
 
any degree of accuracy. The Indian Survey department is primarily
 
engaged in supplying administrative needs ; and although every effort
 
is made in fulfilling this duty to collect information of purely scientific
 
interest, much still remains to be done.
 
 
A brief abstract of our knowledge of the Himalayas may be given by
 
shortly describing the political divisions of India which include them.
 
On the extreme north-west, more than half of the State of KashmIr
 
.AND Jammu lies in the Himalayas, and this portion has been described
 
in some detail by Drew in Jammu and Kashmir Territories^ and by
 
Sir W. Lawrence in The Valley of Kashmir. The next section,
 
appertaining to the Punjab and forming the British District of Kangra
 
and the group of feudatories known as the Simla Hill States, is better
 
known. East of this lies the Kumaun Division of the United Provinces,
 
attached to which is the Tehrl State. This portion has been surveyed
 
in detail, owing to the requirements of the revenue administration, and
 
is also familiar from the careful accounts of travellers.
 
 
For 500 miles
 
the State of Nepal occupies the mountains, and is to the present day
 
almost a terra incognita, owing to the acquiescence by the British
 
Government in the policy of exclusion adopted by its rulers. Our
 
knowledge of the topography of this portion of the Himalayas is limited
 
to the information obtained during the operations of 18 16, materials
 
collected by British  ofificials resident at Katmandu, notably B. H.
 
Hodgson, and the accounts of native explorers. The eastern border
 
of Nepal is formed by the State of Sikkim and the Bengal District
 
of Darjeeling, which have been graphically described by Sir Joseph
 
Hooker and more recently by Mr. Douglas Freshfield. A small
 
wedge of Tibetan territory, known as the Chumbi Valley, separates
 
Sikkim from Bhutan, which latter has seldom been visited by Euro-
 
peans. East of Bhutan the Himalayas are inhabited by savage tribes,
 
Avith whom no intercourse is possible except in the shape of punitive
 
expeditions following raids on the plains. Thus a stretch of nearly 400
 
miles in the eastern portion of the range is imperfectly known.
 
 
In the western part of the Himalayas, which, as has been shown,
 
has been more completely examined than elsewhere, the system may
 
be divided into three portions. The central or main axis is the
 
highest, which, starting at Nanga Parbat on the north-west, follows
 
the general direction of the range. Though it contains numerous
 
lofty peaks, including Nanda Devi, the highest mountain in British
 
India, it is not a true watershed. North of it lies another range, here
 
forming the boundary between India and Tibet, which shuts off the
 
valley of the Indus, and thus may be described as a real water-parting.
 
From the central axis, and usually from the peaks in it, spurs diverge,
 
with a general south-easterly or south-westerly direction, but actually
 
winding to a considerable extent. These spurs, which may be called
 
the Outer Himalayas, cease with some abruptness at their southern
 
extremities, so that the general elevation is 8,000 or 9,000 feet a few
 
miles from the plains. Separated from the Outer Himalayas by
 
elevated valleys or duns is a lower range known as the Siwaliks, which
 
is well marked between the Beas and the Ganges, reappears to the
 
south of central Kumaun, and is believed to exist in Nepal. Although
 
the general character of the Himalayas in Nepal is less accurately
 
known, there is reason to suppose that it approximates to that of the
 
western ranges.
 
 
Within the limits of this great mountain chain all varieties of scenery
 
can be obtained, except the placid charm of level country. Luxuriant
 
vegetation clothes the outer slopes, gradually giving place to more
 
sombre forests. As higher elevations are reached, the very desolation
 
of the landscape affects the imagination even more than the beautiful
 
scenery left behind. It is not surprising that these massive peaks are
 
venerated by the Hindus, and are intimately connected with their
 
religion, as giving rise to some of the most sacred rivers, as well as
 
on account of legendary associations. A recent writer has vividly
 
described the impressions of a traveller through the foreground of
 
a journey to the snows in Sikkim ' : —
 
 
' D. W. Freshfield in The Geographical Journal, vol. xix, p. 453.
 
He sees at one glance the shadowy valleys from which shhiing
 
mist-columns rise at noon against a luminous sky, the forest ridges,
 
stretching fold behind fold in softly undulating lines — dotted by the
 
white specks which mark the situation of Buddhist monasteries — to
 
the glacier-draped pinnacles and precipices of the snowy range. He
 
passes from the zone of tree-ferns, bamboos, orange-groves, and dal
 
forest, through an endless colonnade of tall-stemmed magnolias, oaks,
 
and chestnut trees, fringed with delicate orchids and festooned by long
 
convolvuluses, to the region of gigantic pines, junipers, firs, and larches.
 
Down each ravine sparkles a brimming torrent, making the ferns and
 
flowers nod as it dashes past them. Superb butterflies, black and
 
blue, or flashes of rainbow colours that turn at pleasure into exact
 
imitations of dead leaves, the fairies of this lavish transformation scene
 
of Nature, sail in and out between the sunlight and the gloom. The
 
mountaineer pushes on by a track half buried between the red twisted
 
stems of tree-rhododendrons, hung with long waving lichens, till he
 
emerges at last on open sky and the upper pastures — the Alps of the
 
Himalaya — fields of flowers : of gentians and edelweiss and poppies,
 
which blossom beneath the shining storehouses of snow that encompass
 
the ice-mailed and fluted shoulders of the giants of the range. If there
 
are mountains in the world which combine as many beauties as the
 
Sikkim Himalayas, no traveller has as yet discovered and described
 
them for us.'
 
 
The line of perpetual snow varies from 15,000 to 16,000 feet on the
 
southern exposures. In winter, snow generally falls at elevations above
 
5,000 feet in the west, while falls at 2,500 feet were twice recorded in
 
Kumaun during the last century. Glaciers extend below the region
 
of perpetual snow, descending to 12,000 or 13,000 feet in Kulu and
 
Lahul, and even lower in Kumaun, while in Sikkim they are about
 
2,000 feet higher. On the vast store-house thus formed largely depends
 
the prosperity of Northern India, for the great rivers which derive their
 
water from the Himalayas have a perpetual supply which may diminish
 
in years of drought, but cannot fail absolutely to feed the system of
 
canals drawn from them.
 
 
While all five rivers from which the Punjab derives its name rise
 
in the Himalayas, the Sutlej alone has its source beyond the northern
 
range, near the head-waters of the Indus and Tsan-po. In the next
 
section are found the sources of the Jumna, Ganges, and Kali or Sarda
 
high up in the central snowy range, while the Kauriala or Karnali,
 
known lower down in its course as the Gogra, rises in Tibet, beyond
 
the northern watershed. The chief rivers of Nepal, the Gandak and
 
Kosi, each with seven main affluents, have their birth in the Himalayas,
 
which here supply a number of smaller streams merging in the larger
 
rivers soon after they reach the plains. Little is known of the upper
 
courses of the northern tributaries of the Brahma[)utra in Assam ; but
 
it seems probable that the Dihang, which has been taken as the eastern
 
boundary of the Himalayas, is the channel connecting the Tsan-po and
 
the Brahmaputra.
 
 
Passing from east to west the principal peaks are Nanga Parbat
 
(26,182 feet) in Kashmir; a peak in Spiti (Kangra District) exceed-
 
ing 23,000, besides three over 20,000; Nanda Devi (25,661), Trisul
 
(23,382), Panch Chulhi (22,673), ^"^J Nanda Kot (22,538) in the
 
United Provinces ; Mount Everest (29,002), Devalagiri (26,826),
 
Gosainthan (26,305) and Kinchinjunga (28,146), with several smaller
 
peaks, in Nepal; and Dongkya (23,190), with a few rising above
 
20,000, in Sikkim.
 
 
The most considerable stretch of level ground is the beautiful
 
Kashmir Valley, through which flows the Jhelum. In length about
 
84 miles, it has a breadth varying from 20 to 25 miles. Elsewhere
 
steep ridges and comparatively narrow gorges are the rule, the chief
 
exception being the Valley of Nepal, which is an undulating plain
 
about 20 miles from north to south, and 12 to 14 miles in width.
 
Near the city of Srinagar is the Dal Lake, described as one of the
 
most picturesque in the world. Though measuring only 4 miles by 2^,
 
its situation among the mountains, and the natural beauty of its banks,
 
combined with the endeavours of the Mughal emperors to embellish
 
it, unite to form a scene of great attractions. Some miles away is the
 
larger expanse of water known as the Wular Lake, which ordinarily
 
covers \2\ square miles, but in years of flood expands to over 100.
 
A number of smaller lakes, some of considerable beauty, are situated
 
in the outer ranges in Naini Tal District. \\\ 1903 the Gohna Lake,
 
in Garhwal District, was formed by the subsidence of a steep hill, rising
 
4,000 feet above the level of a stream which it blocked.
 
 
The geological features of the Himalayas can be conveniently
 
grouped into three classes, roughly corresponding to the three main
 
orographical zones : (i) the Tibetan highland zone, (2) the zone of
 
snowy peaks and Outer Himalayas, and (3) the Sub-Himalayas.
 
 
In the Tibetan highlands there is a fine display of marine fossiliferous
 
rocks, ranging in age from Lower Palaeozoic to Tertiary. In the zone
 
of the snowy peaks granites and crj-stalline schists are displayed, fringed
 
by a mantle of unfossiliferous rocks of old, but generally unknown, age,
 
forming the lower hills or Outer Himalayas, while in the Sub-Himalayas
 
the rocks are practically all of Tertiary age, and are derived from the
 
waste of the highlands to the north.
 
 
The disposition of these rocks indicates the existence of a range
 
of some sort since lower palaeozoic times, and shows that the present
 
southern boundary of the marine strata on the northern side of the
 
crystalline axis is not far from the original shore of the ocean in which
 
these strata were laid down. The older unfossiliferous rocks of the
 
By T. H, Holland, Geological Survey of India.
 
Lower Himalayas on the southern side of the main crystalline axis are
 
more nearly in agreement with the rocks which ha\e been preserved
 
without disturbance in the Indian Peninsula; and even remains of the
 
great Gondwana river-formations which include our valuable deposits
 
of coal are found in the Darjeeling area, involved in the folding move-
 
ments which in later geological times raised the Himalayas to be the
 
greatest among the mountain ranges of the world. The Himalayas
 
were thus marked out in very early times, but the main folding took
 
place in the Tertiary era. The great outflow of the Deccan trap was
 
followed by a depression of the area to the north and west, the sea in
 
eocene times spreading itself over Rajputana and the Indus valley,
 
covering the Punjab to the foot of the Outer Himalayas as far east as
 
the Ganges, at the same time invading on the east the area now-
 
occupied by Assam. Then followed a rise of the land and consequent
 
retreat of the sea, the fresh-water deposits which covered the eocene
 
marine strata being involved in the movement as fast as they were
 
formed, until the Sub-Himalayan zone river-deposits, no older than the
 
pliocene, became tilted up and even overturned in the great foldings
 
of the strata. This final rise of the Himalayan range in late Tertiary
 
times was accompanied by the movements which gave rise to the
 
Arakan Yoma and the Naga Hills on the east, and the hills of
 
Baluchistan and Afghanistan on the west.
 
 
The rise of the Himalayan range may be regarded as a great buckle
 
in the earth's crust, which raised the great Central Asian plateau in
 
late Tertiary times, folding over in the Baikal region on the north
 
against the solid mass of Siberia, and curling over as a great wave on
 
the south against the firmly resisting mass of the Indian Peninsula.
 
 
As an index to the magnitude of this movement within the Tertiary
 
era, we find the marine fossil foraniinifer, Nii>nmuiites, which lived in
 
eocene times in the ocean, now at elevations of 20,000 feet above
 
sea-level in Zaskar. With the rise of the Himalayan belt, there
 
occurred a depression at its southern foot, into which the alluvial
 
material brought down from the hills has been dropped by the rivers.
 
In miocene times, when presumably the Himalayas did not possess
 
their present elevation, the rivers deposited fine sands and clays in this
 
area ; and as the elevatory process went on, these deposits became
 
tilted up, while the rivers, attaining greater velocity with their increased
 
gradient, brought down coarser material and formed conglomerates in
 
pliocene times. These also became elevated and cut into by their
 
own rivers, which are still working along their old courses, bringing
 
down boulders to be deposited at the foot of the hills and carrying out
 
the finer material farther over the Indo-Gangctic plain.
 
 
The series of rocks which have thus been formed by the rivers, and
 
afterwards raised to form the Sub-Himalayas, are known as the Siwalik
 
series. They are divisible into three stages. In the lowest and oldest,
 
distinguished as the Nahan stage, the rocks are fine sandstones and red
 
clays without any pebbles. In the middle stage, strings of pebbles are
 
found with the sandstones, and these become more abundant towards
 
the top, until we reach the conglomerates of the upper stage. Along the
 
whole length of the Himalayas these Siwalik rocks are cut off from
 
the older rock systems of the higher hills by a great reversed fault,
 
which started in early Siwalik times and developed as the folding
 
movements raised the mountains and involved in its rise the deposits
 
formed along the foot of the range. The Siwalik strata never extended
 
north of this great boundary fault, but the continued rise of the
 
mountains affected these deposits, and raised them up to form the
 
outermost zone of hills.
 
 
The upper stage of the Siwalik series is famous on account of the rich
 
collection of fossil vertebrates which it contains. Among these there
 
are forms related to the miocene mammals of Europe, some of which,
 
like the hippopotamus, are now unknown in India but have relatives in
 
Africa. Many of the mammals now characteristic of India were repre-
 
sented by individuals of much greater size and variety of species in
 
Siwalik times.
 
 
The unfossiliferous rocks which form the Outer Himalayas are of
 
unknown age, and may possibly belong in part to the unfossiliferous
 
rocks of the Peninsula, like the Vindhyans and the Cuddapahs.
 
Conspicuous among these rocks are the dolomitic limestones of Jaunsar
 
and Kumaun, the probable equivalents of the similar rocks far away to
 
the east at Buxa in the Duars. With these a series of purple quartzites
 
and basic lava-flow is often associated. In the Simla area the un-
 
fossiliferous rocks have been traced out with considerable detail ; and
 
it has been shown that quartzites, like those of Jaunsar and Kumaun,
 
are overlaid by a system of rocks which has been referred to the
 
carbonaceous system on account of the black carbonaceous slates
 
which it includes. The only example known of pre-Tertiary fossiliferous
 
rocks south of the snowy range in the Himalayas occurs in south-west
 
Garhwal, where there are a few fragmentary remains of mesozoic fossils
 
of marine origin.
 
 
The granite rocks, which form the core of the snowy range and in
 
places occur also in the Lower Himalayas, are igneous rocks which
 
may have been intruded at different periods in the history of the range.
 
They are fringed with crystalline schists, in which a progressive
 
metamorphism is shown from the edge of granitic rock outwards, and
 
in the inner zone the granitic material and the pre-existing sedimentary
 
rock have become so intimately mixed that a typical banded gneiss is
 
produced. The resemblance of these gneisses to the well-known
 
gneisses of Archaean age in the Peninsula and in other parts of the
 
world led earlier observers to suppose that the gneissose rocks of
 
the Central Himalayas formed an Archaean core, against which the
 
sediments were subsequently laid down. But as we now know for
 
certain that both granites, such as we have in the Himalayas, and
 
banded gneisses may be much ycjunger, even Tertiary in age, the mere
 
composition and structure give no clue to the age of the crystalline
 
axis. The position of the granite rock is probably dependent on the
 
development of low-pressure areas during the process of folding, and
 
there is thus a prima facie reason for supposing that much of the
 
igneous material became injected during the Tertiary period. With
 
the younger intrusions, however, there are probably remains of injections
 
which occurred during the more ancient movements, and there may
 
even be traces of the very ancient Archaean gneisses ; for we know that
 
pebbles of gneisses occur in the Cambrian conglomerates of the Tibetan
 
zone, and these imply the existence of gneissose rocks exposed to the
 
atmosphere in neighbouring highlands. The gneissose granite of the
 
Central Himalayas must have consolidated under great pressure, with
 
a thick superincumbent envelope of sedimentary strata ; and their
 
exposure to the atmosphere thus implies a long period of effectual
 
erosion by weathering agents, which have cut down the softer sediments
 
more easily and left the more resisting masses of crystalline rocks to
 
form the highest peaks in the range. Excellent illustrations of the
 
relationship of the gneissose granites to the rocks into which they
 
have been intruded are displayed in the Dhaola Dhar in Kulu, in the
 
Chor Peak in Garhwal, and in the Darjeeling region east of Nepal.
 
 
Beyond the snowy range in the Tibetan zone we have a remarkable
 
display of fossiliferous rocks, which alone would have been enough to
 
make the Himalayas famous in the geological world. The boundary
 
between Tibetan territory and Spiti and Kumaun has been the area
 
most exhaustively studied by the Geological Survey. The rocks exposed
 
in this zone include deposits which range in age from Cambrian to
 
Tertiary. The oldest fo.ssiliferous system, distinguished as the Haimanta
 
('snow-covered') system, includes some 3,000 feet of the usual sedi-
 
mentary types, with fragmentary fossils which indicate Cambrian and
 
Silurian affinities. Above this system there are representatives of the
 
Devonian and Carboniferous of Europe, followed by a conglomerate
 
which marks a great stratigraphical break at the beginning of Permian
 
times in Northern India. Above the conglomerate comes one ol the
 
most remarkably complete succession of sediments known, ranging from
 
Permian, without a sign of disturbance in the process of sedimentation,
 
throughout The whole Mesozoic epoch to the beginning of Tertiary
 
times. The highly fossiliferous character of some of the formations in
 
this great pile of strata, like the Proditdus shales and the Spiti shales,
 
has made this area classic ground to the palaeontologist.
 
 
vol.. XIII. K
 
The Eurasian ocean distinguished by the name 'Thetys,' which
 
spread over this area throughout the Palaeozoic and Mesozoic times,
 
became driven back by the physical revolution which began early in
 
Tertiary times, when the folding movements gave rise to the modern
 
Himalayas. As relics of this ocean have been discovered in Burma and
 
China it will not be surprising to find, when the ground has been more
 
thoroughly explored, that highly fossiliferous rocks are preserved also
 
in the Tibetan zone beyond the snowy ranges of Nepal and Sikkim.
 
 
Of the minerals of value, graphite has been recorded in the Kumaun
 
Division ; coal occurs frequently amongst the Nummulitic (eocene)
 
rocks of the foot-hills and the Gondwana strata of Darjeeling District ;
 
bitumen has been found in small quantities in Kumaun ; stibnite, a
 
sulphide of antimony, occurs associated with ores of zinc and lead in
 
well-defined lodes in Lahul ; gold is obtained in most of the rivers,
 
and affords a small and precarious living for a few washers ; copper
 
occurs very widely disseminated and sometimes forms distinct lodes of
 
value in the slaty series south of the snowy range, as in the Kulu,
 
Kumaun, and Darjeeling areas ; ferruginous schists sometimes rich in
 
iron occur under similar geological conditions, as in Kangra and
 
Kumaun ; sapphires of considerable value have been obtained in
 
Zaskar and turquoise from the central highlands ; salt is being mined
 
in quantity from near the boundary of the Tertiary and older rocks
 
in the State of Mandi ; borax and salt are obtained from lakes beyond
 
the Tibetan border ; slate-quarrying is a flourishing industry along the
 
southern slopes of the Dhaola Dhar in Kangra District ; mica of poor
 
quality is extracted from the pegmatites of Kulu ; and a few other
 
minerals of little value, besides building stones, are obtained in various
 
places. A small trade is developed, too, by selling the fossils from the
 
Spiti shales as sacred objects.
 
 
The general features of the great variety in vegetation have been
 
illustrated in the quotation from Mr. Freshfield's description of Sikkim.
 
These variations are naturally due to an increase in elevation, and to
 
the decrease in rainfall and humidity passing from south to north, and
 
from east to west. The tropical zone of dense forest extends up to
 
about 6,500 feet in the east, and 5,000 feet in the west. In the
 
Eastern Himalayas orchids are numerically the predominant order of
 
flowering plants ; while in Kumaun about 62 species, both epiphytic
 
and terrestrial, have been found. A temperate zone succeeds, ranging
 
to about 12,000 feet, in which oaks, pines, and tree-rhododendrons are
 
conspicuous, with chestnut, maple, magnolia, and laurel in the east.
 
Where rain and mist are not excessive, as for example in Kulu and
 
Kumaun, European fruit trees (apples, pears, apricots, and peaches)
 
have been naturalized very successfully, and an important crop of
 
potatoes is obtained in the west. Above about 12,000 feet the forests
 
become thinner. Birch and willow mixed with dwarf rhododendrons
 
continue for a time, till the open pasture land is reached, which is
 
richly adorned in the summer months with brilliant Alpine species of
 
flowers. Contrasting the western with the eastern section we find that
 
the former is far less rich, though it has been better explored, while
 
there is a preponderance of European species. A fuller account of the
 
botanical features of the Himalayas will be found in Vol. I, chap. iv.
 
 
To obtain a general idea of the fauna of the Himalayas it is
 
sufificient to consider the whole system as divided into two tracts :
 
namely, the area in the lower hills where forests can flourish, and the
 
area above the forests. The main characteristics of these tracts have
 
been summarized by the late Dr. W. T. Blanford^ In the forest
 
area the fauna differs markedly from that of the Indian Peninsula
 
stretching away from the base of the hills. It does not contain the
 
so-called Aryan element of mammals, birds, and reptiles which are
 
related to Ethiopian and Holarctic genera, and to the pliocene Siwalik
 
fauna, nor does it include the Dravidian element of reptiles and
 
batrachians. On the other hand, it includes the following animals
 
which do not occur in the Peninsula — Mammals : the families Simiidae,
 
Procyonidae, Talpidae, and Spalacidae, and the sub-family Gymnurinae,
 
besides numerous genera, such as Frionodon, Helictis, Anfonyx, Athe-
 
rura, IVemorhaedus, and Cemas. Birds : the families Eurylaemidae,
 
Indicatoridae, and Heliornithidae, and the sub-family Paradoxornithinae.
 
Reptiles : Platysternidae and Anguidae. Batrachians : Dyscophidae,
 
Hylidae, Pelobatidae, and Salamandridae. Compared with the Penin-
 
sula, the fauna of the forest area is poor in reptiles and batrachians.
 
 
' It also contains but few peculiar genera of mammals and birds, and
 
almost all the peculiar types that do occur have Holarctic affinities.
 
The Oriental element in the fauna is very richly represented in the
 
Eastern Himalayas and gradually diminishes to the westward, until in
 
Kashmir and farther west it ceases to be the principal constituent.
 
These facts are consistent with the theory that the Oriental constituent
 
of the Himalayan fauna, or the greater portion of it, has migrated into
 
the mountains from the eastward at a comparatively recent period. It
 
is an important fact that this migration appears to have been from
 
Assam and not from the Peninsula of India.'
 
 
Dr. Blanford suggested that the explanation was to be found in the
 
conditions of the glacial epoch. When the spread of snow and ice
 
took place, the tropical fauna, which may at that time have resembled
 
more closely that of the Peninsula, was forced to retreat to the base
 
of the mountains or perished. At such a time the refuge afforded by
 
the Assam Valley and the hill ranges south of it, with their damp,
 
 
' 'The Distribution of Vcrtcl)rale Animals in India, Ceylon, and IJurnia,' Pio-
 
cecdtngs, Royal Socrc/y, vol. Ixvii, p. 484.
 
sheltered, forest-clud valleys, would be more secure than the open
 
plains of Northern India and the drier hills of the country south of
 
these. As the cold epoch passed away, the Oriental fauna re-entered
 
the Himalayas from the east.
 
 
Above the forests the Himalayas belong to the Tibetan sub-region
 
of the Holarctic region, and the fauna differs from that of the Indo-
 
Malay region, 44 per cent, of the genera recorded from the Tibetan
 
tract not being found in the Indo-Malay region. During the glacial
 
epoch the Holarctic forms apparently survived in great numbers.
 
 
Owing to the rugged nature of the country, which makes travelling
 
difficult and does not invite immigrants, the inhabitants of the
 
Himalayas present a variety of ethnical types which can hardly be
 
summarized briefly. Two common features extending over a large
 
area may be referred to. From Ladakh in Kashmir to Bhutan are
 
found races of Indo-Chinese type, speaking dialects akin to Tibetan
 
and professing Buddhism. In the west these features are confined to
 
the higher ranges ; but in Sikkim, Darjeeling, and Bhutan they are
 
found much nearer the plains of India. Excluding Burma, this tract
 
of the Himalayas is the only portion of India in which Buddhism is
 
a living religion. As in Tibet, it is largely tinged by the older
 
animistic beliefs of the people. Although the Muhammadans made
 
various determined efforts to conquer the hills, they were generally
 
unsuccessful, yielding rather to the difficulties of transport and climate
 
than to the forces brought against them by the scanty though brave
 
population of the hills. In the twelfth century a Tartar horde invaded
 
Kashmir, but succumbed to the rigours of the snowy passes. Sub-
 
sequently a Tibetan soldier of fortune seized the supreme power and
 
embraced Islam. Late in the fourteenth century the Muhammadan
 
ruler of the country. Sultan Sikandar, pressed his religion by force on
 
the people, and in the province of Kashmir proper 94 per cent, of the
 
total are now Muhammadans.
 
 
Baltistan is also inhabited chiefly by
 
Muhammadans, but the proportion is much less in Jammu, and beyond
 
the Kashmir State Islam has few followers. Hinduism becomes an
 
important religion in Jammu, and is predominant in the southern
 
portions of the Himalayas within the Punjab and the United Provinces.
 
It is the religion of the ruling dynasty in Nepal, where, however,
 
Buddhism is of almost equal strength. East of Nepal Hindus are few.
 
Where Hinduism prevails, the language in common use, known as
 
Paharl, presents a strong likeness to the languages of Rajputana, thus
 
confirming the traditions of the higher classes that their ancestors
 
migrated from the plains of India. In Nepal the languages spoken
 
are more varied, and Newari, the ancient state language, is akin to
 
Tibetan. The Mongolian element in the population is strongly
 
marked in the east, but towards the west has been pushed back into the higher portion of the ranges. In Kumaun arc found a few shy
 
people living in the recesses of the jungles, and having little intercourse
 
with their more civilized neighbours. Tribes which appear to be akin
 
to these are found in Nepal, but little is known about them. North
 
of Assam the people are of Tibeto-Burman origin, and are styled,
 
passing from west to east, the Akas, Daflas, Miris, and Abors, the last
 
name signifying 'unknown savages.' Colonel Dalton has described
 
these people in his Ethnology of Bengal.
 
 
From the commercial point of view the agricultural products of the
 
Himalayas, with few exceptions, are of little importance. The chief
 
food-grains cultivated are, in the outer ranges, rice, wheat, barley,
 
mariid, and amaranth. In the hot, moist valleys, chillies, turmeric,
 
and ginger are grown. At higher levels potatoes have become an
 
important crop in Kumaun ; and, as already mentioned, in Kulu and
 
Kumaun European fruits have been successfully naturalized^ including
 
apples, pears, cherries, and strawberries. Two crops are obtained in
 
the lower hills ; but cultivation is attended by enormous difficulties,
 
owing to the necessity of terracing and clearing land of stones, while
 
irrigation is practicable only by long channels winding along the hill-
 
.sides from the nearest suitable stream or spring. As the snowy ranges
 
are approached wheat and buckwheat, grown during the summer
 
months, are the principal crops, and only one harvest in the year
 
can be obtained. Tea gardens were successfully established in
 
Kumaun during the first half of the nineteenth century, but the most
 
important gardens are now situated in Kangra and Darjeeling. In
 
the latter District cinchona is grown for the manufacture of quinine
 
and cinchona febrifuge.
 
 
The most valuable forests are found in the Outer Himalayas,
 
yielding a number of timber trees, among which may be mentioned
 
sal, shtshajH {Dalbergia Sissoo), and tun {Cedrela toona). Higher u[)
 
are found the deodar and various kinds of pine, which are also
 
extracted wherever means of transport can be devised. In the Eastern
 
Himalayas wild rubber is collected by the hill tribes already mentioned,
 
and brought for sale to the Districts of the Assam Valley.
 
 
Communications within the hills are naturally difficult. Railways
 
have hitherto been constructed only to three places in the outer hills :
 
Jammu in the Kashmir State, Simla in the Punjab, and Darjeeling in
 
Bengal. Owing to the steepness of the hill-sides and the instability of
 
the strata composing them, these lines have been costly to build and
 
maintain. A more ambitious project is now being carried out to
 
connect the Kashmir valley with the plains, motive power being
 
supplied by electricity to be generated by the Jhelum river. The
 
principal road practicable for wheeled traffic is also in Kashmir,
 
leading from Rawalpindi in the i)!ains ihrougli Murixc and liaraniula
 
to Srinagar, Other cart-roads have been made connecting with the
 
plains the hill stations of Dharmsala, Simla, Chakrata, Mussoorie,
 
Dalhousie, Naini Tal, and Ranlkhet, In the interior the roads are
 
merely bridle-paths. The great rivers flowing in deep gorges are
 
crossed by suspension bridges made of the rudest materials.
 
 
The
 
sides consist of canes and twisted fibres, and the footway may be
 
a single bamboo laid on horizontal canes supported by ropes attached
 
to the sides. These frail constructions, oscillating from side to side
 
under the tread of the traveller, are crossed with perfect confidence by
 
the natives, even when bearing heavy loads. On the more frequented
 
paths, such as the pilgrim road from Hardwar up the valley of the
 
Ganges to the holy shrines of Badrinath and Kedarnath, more sub-
 
stantial bridges have been constructed by Government, and the roads
 
are regularly repaired. Sheep and, in the higher tracts, yaks and
 
crosses between the yak and ordinary cattle are used as beasts of
 
burden. The trade with Tibet is carried over lofty passes, the
 
difficulties of which have not yet been ameliorated by engineers.
 
Among these the following may be mentioned : the Kangwa La
 
(15,500 feet) on the Hindustan-Tibet road through Simla; the Mana
 
(18,000), NitI (16,570), and Balcha Dhura in Garhwal ; the Anta
 
Dhura (17,270), Lampiya Dhura (18,000), and Lipu Lekh (16,750)
 
in Almora ; and the Jelep La (14,390) in Sikkim.

=Contribution to ecology, economy=
 
== ‘An aerosol factory’==

Aerosols are not entirely well understood. Most cool the planet, some have a warming effect. Some make clouds last longer, others make them disappear. Just about 10% are human-generated and the rest, naturally occurring, are barely understood. But scientists have now found that nearly every day for centuries now, winds blasting up from the forests on the foothills of the Everest, through the valleys to the sky-piercing summit, have been working up an “aerosol factory.”
 
 
A study by 29 scientists from Finland, Italy, Switzerland, the US, France, Estonia and China published in ‘Nature Geoscience’ last week recorded observations from the remote Nepal Climate Observatory Pyramid station at 5,079m above sea level, a few kilometres from the summit .
 
 
“The concept of the Himalaya aerosol factory is that you need processes to form particles — the trees, the mountains, the wind,” lead author Federico Bianchi from the University of Helsinki in Finland told TOI. So far, it had been assumed that there might be aerosols that high up but measurements have been extremely limited.
 
 
“Plants at the foothills of the Himalayas emit large quantities of gases. These are transported by the wind through the valley to high altitudes. These gases (while they are transported) react in the air with atmospheric oxidants and form tiny particles,” Bianchi said. The initial size of these particles is 1-2 nanometre. But, by the time they approach the summit, they reach the size of 50-100 nm and become seeds for clouds.
 
So, what impact do they have on climate change?
 
So far, the general scientific consensus is that the cooling effect of aerosols has been able to partially counter the warming effect of greenhouse gases since the late 19th century. Dr Bianchi added, “This new source of particles can now be used in climate models for better climate change predictions and modelling future scenario.”

=== Himalayas “subside/ move up” depending on groundwater levels===

The mighty Himalayas “subside and move up” depending on the seasonal changes in groundwater, said a new study, flagged by science ministry. It noted this as a unique phenomena where mountains literally “dance” to the tune of our groundwater consumption in the region.
 
 
Simply put, sinking of Himalayan foothills and the Indo-Gangetic plain now cannot be attributed only to geological phenomena (tectonic activity associated with landmass movement or continental drift) but also to variations of water availability beneath the ground.
 
 
Researchers from Indian Institute of Geomagnetism (IIG), in their study published recently in the Journal of Geophysical Research, through the combined use of Global Positioning System(GPS) and Gravity Recovery And Climate Experiment (GRACE) data quantified the variations of hydrological mass.
 
“Nobody till now has looked at the rising Himalayas from a hydrological standpoint,” said the department of science & technology (DST) of the ministry which funded the study, noting how IIG’s Ajish Saji and other scientists looked at this phenomenon through this innovative prism using satellite data.
 
 
The GRACE satellites, launched by the US in 2002, monitor changes in water and snow stores on the continents. The study, which analysed the data, finds that an unsustainable consumption of groundwater associated to irrigation and other anthropogenic uses influence the subsidence rate in the Indo-Gangetic plain and sub-Himalayas.

==2016/ Mediterranean black carbon might be polluting Himalayas==

A recent study by the Dehradun-based Wadia Institute of Himalayan Geology (WIHG) has found that black carbon travelling from Mediterranean countries during the western disturbance (which brings winter rains to India) may be one of the contributing factors leading to the receding snowline in the Himalayas.
 
 
Black carbon is formed through the incomplete combustion of fossil fuels, biofuel etc. The study recorded data for 12 months from January to December 2016 at Gangotri Glacier Valley in Chirbasa at an altitude of 3600 meters above sea level. Scientists involved in the study found that black carbon concentration at the site was high even in winter months although the area did not have any marked human activity which could have contributed to the pollution.
 
 
“The high concentration of black carbon in January and February is not originating from local sources because the entire population in these areas migrates to the plains for the winter.” said PS Negi, senior scientist, WIHG, Dehradun.
 
 
He added that “western disturbance is an extratropical storm originating from the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.” “The material present in the atmosphere also gets transported during the western disturbance and this is what is impacting the environment and ecology of Himalayas.” Studies had earlier found a co-relation between black carbon concentration and melting of glaciers.
