The banks being thus ingeniously protected from the action of the air above, and of the water at their base, other herbaceous plants soon cover them in quick succession, and give the entire surface the first aspect of vegetation. A little retired above high water are to be found a species of _Aristolochia_[1], the Sayan[2], or _Choya_, the roots of which are the Indian Madder (in which, under the Dutch Government, some tribes in the Wanny paid their tribute); the gorgeous _Gloriosa superba_, the beautiful _Vistnu-karandi_[3] with its profusion of blue flowers, which remind one of the English "Forget-me-not," and the thickly-matted verdure of the _Hiramana-doetta_[4], so well adapted for imparting consistency to the soil. In the next stage low shrubs make their appearance, their seeds being drifted by the waves and wind, and taking ready root wherever they happen to rest. The foremost of these are the Scævolas[5] and Screw Pines[6], which grow luxuriantly within the actual wash of the tide, while behind them rises a dense growth of peculiar plants, each distinguished by the Singhalese by the prefix of "Moodu," to indicate its partiality for the sea.[7]
[Footnote 1: _Aristolocia bracteata_. On the sands to the north of Ceylon there is also the _A. Indica_, which forms the food of the great red and white butterfly (_Papilio Hector_).]

Amongst these marine shrubs the Nil-picha (_Guettarda speciosca_), with its white and delightfully fragrant flowers, is a conspicuous object on some parts of the sea-shore between Colombo and Point-de-Galle.]
Where the sand in the lagoons and estuaries is more or less mingled with the alluvium brought down by the rivers, there are plants of another class which are equally characteristic. Amongst these the Mangroves[1] take the first place in respect to their mass of vegetation; then follow the Belli-patta[2] and Suriya-gaha[3], with their large hibiscus-like flowers; the Tamarisks[4]; the Acanthus[5], with its beautiful blue petals and holly-like leaves; the Water Coco-nut[6]; the Ægiceras and Hernandia[7], with its sonorous fruits; while the dry sands above are taken possession of by the Acacias, _Salvadora Persica_ (the true mustard-tree of Scripture[8], which, here attains a height of forty feet), Ixoras, and the numerous family of Cassias.

[Footnote 3: Thespesia populnea.]
[Footnote 4: Tamarix Indica.]
[Footnote 5: Dilivaria ilicifolia.]
[Footnote 6: Nipa fruticans.]
[Footnote 7: Hernandia sonora.]
[Footnote 8: The identification of this tree with the mustard-tree alluded to by our Saviour is an interesting fact. The Greek term [Greek: sinapis], which occurs Matt. xiii 31, and elsewhere, is the name given to _mustard_; for which the Arabic equivalent is _chardul_ or _khardal_, and the Syriac _khardalo_. The same name is applied at the present day to a tree which grows freely in the neighbourhood of Jerusalem, and generally throughout Palestine; the seeds of which, have an aromatic pungency, which enables them to be used instead of the ordinary mustard (_Sinapis nigra_); besides which, its structure presents all the essentials to sustain the illustration sought to be established in the parable, some of which are wanting or dubious in the common plant, It has a very small seed; it may be sown in a garden: it grows into an "herb," and eventually "becometh a tree; so that the birds of the air come and lodge in the branches thereof." With every allowance for the extremest development attainable by culture, it must be felt that the dimensions of the domestic _sinapis_ scarcely justify the last illustration; besides which it is an annual, and cannot possibly be classed as a "tree." The khardal grows abundantly in Syria: it was found in Egypt by Sir Gardner Wilkinson; in Arabia by Bové; on the Indus by Sir Alexander Burnes; and throughout the north-west of India it bears the name of kharjal. Combining all these facts, Dr. Royle, in an erudite paper, has shown demonstrative reasons for believing that the _Salvadora Persica_, the "kharjal" of Hindostan, is the "khardal" of Arabia, the "chardul" of the Talmud, and the "mustard-tree" of the parable.]
Lastly, after a sufficiency of earth has been formed by the decay of frequent successions of their less important predecessors, the ground becomes covered by trees of ampler magnitude, most of which are found upon the adjacent shores of the mainland--the Margoza[1], from whose seed the natives express a valuable oil; the Timbiri[2], with the glutinous nuts with which the fishermen "bark" their nets; the Cashu-nut[3]; the Palu[4], one of the most valuable timber trees of the Northern Provinces; and the Wood-apple[5], whose fruit is regarded by the Singhalese as a specific for dysentery.
[Footnote 1: Azadirachta Indica.]
[Footnote 2: Diospyros glutinosa.]
[Footnote 3: Anacardium occidentale.]
[Footnote 4: Mimusopa hexandra.]
[Footnote 5: Ægle marmelos.]
But the most important fact connected with these recently formed portions of land, is their extraordinary suitability for the growth of the coco-nut, which requires the sea-air (and in Ceylon at least appears never to attain its full luxuriance when removed to any considerable distance from it)[1], and which, at the same time, requires a light and sandy soil, and the constant presence of water in large quantities. All these essentials are combined in the sea-belts here described, lying as they do between the ocean on the one side and the fresh-water lakes formed by the great rivers on the other, thus presenting every requisite of soil and surface. It is along a sand formation of this description, about forty miles long and from one to three miles broad, that thriving coco-nut plantations have been recently commenced at Batticaloa. At Calpentyn, on the western coast, a like formation has been taken advantage of for the same purpose. At Jaffna somewhat similar peculiarities of soil and locality have been seized on for this promising cultivation; and, generally, along the whole seaborde of Ceylon to the south and west, the shore for the breadth of one or two miles exhibits almost continuous groves of coco-nut palms.
[Footnote 1: Coco-nuts are cultivated at moderate elevations in the mountain villages of the Interior; but the fruit bears no comparison, in number, size, or weight, with that produced in the lowlands, and near the sea, on either side of the island.]
_Harbours_.--With the exception of the estuaries above alluded to, chiefly in the northern section of the island, the outline of the coast is interrupted by few sinuosities. There are no extensive inlets, or bays, and only two harbours--that of _Point-de-Galle_ which, in addition to being incommodious and small, is obstructed by coral rocks, reefs of which have been upreared to the surface, and render the entrance critical to strange ships[1]; and the magnificent basin of Trincomalie, which, in extent, security, and beauty, is unsurpassed by any haven in the world.
[Footnote 1: Owing to the obstructions at its entrance, Galle is extremely difficult of access in particular winds. In 1857 it was announced in the _Colombo Examiner_ that "the fine ship the 'Black Eagle' was blown out of Galle Roads the other day, with the pilot on board; whilst the captain was temporarily engaged on shore; and as she was not able to beat in again, she made for Trincomalie, where she has been lying for a fortnight. Such an event is by no means unprecedented at Galle."--_Examiner_, 20 Sept. 1857.]
_Tides_.--The variation of the tides is so slight that navigation is almost unaffected by it. The ordinary rise and fall is from 18 to 24 inches, with an increase of about a third at spring tides. High water is later on the eastern than on the western coast; occurring, on full and new moon, a little after eleven o'clock at Adam's Bridge, about 1 o'clock at Colombo, and 1.25 at Galle, whilst it attains its greatest elevation between 5 and 6 o'clock in the harbour of Trincomalie.
_Red infusoria_.--On both sides of the island (but most frequently at Colombo), during the south-west monsoon, a broad expanse of the sea assumes a red tinge, considerably brighter than brick-dust; and this is confined to a space so distinct that a line seems to separate it from the green water which flows on either side. Observing that the whole area changed its position without parting with any portion of its colouring, I had some of the water brought on shore, and, on examination with the microscope, it proved to be filled with _infusoria_, probably similar to those which have been noticed near the shores of South America, and whose abundance has imparted a name to the "Vermilion Sea" off the coast of California.
THE POPULATION OF CEYLON, of all races, was, in 1857, 1,697,975; but this was exclusive of the military and their families, both Europeans and Malays, which together amounted to 5,430; and also of aliens and other casual strangers, forming about 25,000 more.

CHAP. II.
CLIMATE.--HEALTH AND DISEASE.
The climate of Ceylon, from its physical configuration and insular detachment, contrasts favourably with that of the great Indian peninsula. Owing to the moderate dimensions of the island, the elevation of its mountains, the very short space during which the sun is passing over it[1] in his regression from or approach to the solstices, and its surrounding seas being nearly uniform in temperature, it is exempt from the extremes of heating and cooling to which the neighbouring continent of India is exposed. From the same causes it is subjected more uniformly to the genial influences of the trade winds that blow over the Indian Ocean and the Bay of Bengal.
[Footnote 1: In his approach to the northern solstice, the sun, having passed the equator on the 21st of March, reaches the south of Ceylon about the 5th of April, and ten days later is vertical over Point Pedro, the northern extremity of the island. On his return he is again over Point Pedro about the 27th of August, and passes southward over Dondera Head about the 7th of September.]
The island is seldom visited by hurricanes[1], or swept by typhoons, and the breeze, unlike the hot and arid winds of Coromandel and the Dekkan, is always more or less refreshing. The range of the thermometer exhibits no violent changes, and never indicates a temperature insupportably high. The mean on an annual average scarcely exceeds 80° at Colombo, though in exceptional years it has risen to 86°. But at no period of the day are dangerous results to be apprehended from exposure to the sun; and except during parts of the months of March, and April, there is no season when moderate exercise is not practicable and agreeable. For half the year, from October to May, the prevailing winds are from the north-east, and during the remaining months the south-west monsoon blows steadily from the great Indian Ocean. The former, affected by the wintry chills of the vast tracts of land which it traverses before crossing the Bay of Bengal, is subject to many local variations and intervals of calm. But the latter, after the first violence of its outset is abated, becomes nearly uniform throughout the period of its prevalence, and presents the character of an on-shore breeze extending over a prodigious expanse of sea and land, and exerting a powerful influence along the regions of southern Asia.
[Footnote 1: The exception to the exemption of Ceylon from hurricanes is the occasional occurrence of a cyclone extending its circle till the verge has sometimes touched Batticaloa, on the south-eastern extremity of the island, causing damage to vegetation and buildings. Such an event is, however, exceedingly rare. On the 7th of January, 1805, H.M.S. "Sheerness" and two others were driven on shore in a hurricane at Trincomalie.]
In Ceylon the proverbial fickleness of the winds, and the uncertainty which characterises the seasons in northern climates, is comparatively unknown; and the occurrence of changes or rain may be anticipated with considerable accuracy in any month of a coming year. There are, of course, abnormal seasons with higher ranges of temperature, heavier rains, or droughts of longer continuance, but such extremes are exceptional and rare. Great atmospheric changes occur only at two opposite periods of the year, and so gradual is their approach that the climate is monotonous, and one longs to see again "the falling of the leaf" to diversify the sameness of perennial verdure. The line is faint which divides the seasons. No period of the year is divested of its seed-time and its harvest in some part of the island; and fruit hangs ripe on the same branches that are garlanded with opening buds. But as every plant has its own period for the production of its flowers and fruit, each month is characterised by its own peculiar flora.
As regards the foliage of the trees, it might be expected that the variety of tints would be wanting which forms the charm of a European landscape, and that all nature would wear one mantle of unchanging green. But it has been remarked by a tasteful observer[1] that such is far from the fact, and though in Ceylon there is no revolution of seasons, the change of leaf on the same plant exhibits colours as bright as those which tinge the autumnal woods of America. It is not the decaying leaves, but the fresh shoots, which exhibit these brightened colours, the older are still vividly green, whilst the young are bursting forth; and the extremities of the branches present tufts of pale yellow, pink, crimson, and purple, which give them at a distance the appearance of a cluster of flowers.[2]
[Footnote 1: Prof. Harvey, Trin. Coll. Dublin.]
[Footnote 2: Some few trees, such as the margosa (_Azadirachta Indica_), the country almond (_Terminalia catappa_), and others, are deciduous, and part with their leaves. The cinnamon shoots forth in all shades from bright yellow to dark crimson. The maella _(Olax Zeylanica)_ has always a copper colour; and the ironwood trees of the interior have a perfect blaze of young crimson leaves, as brilliant as flowers. The lovi-lovi (_Flacourtia inermis_) has the same peculiarity; while the large bracts of the mussænda (_Mussænda frondosa_) attract the notice of Europeans for their angular whiteness.]
A notice of the variations exhibited by the weather at Colombo may serve as an index to the atmospheric condition of the rest of the island, except in those portions (such as the mountains of the interior, and the low plains of the northern extremity) which exhibit modifications of temperature and moisture incident to local peculiarities.
[Sidenote: Wind N.E. Temperature, 24 hours: Mean greatest 85.6º Mean least 69.2º Rain (inches) 3.1]
_January_.--At the opening of the year, the north-east monsoon, which sets in two months previously, is nearly in mid career. This wind, issuing from the chill north and robbed of its aqueous vapour in passing over the elevated mountain regions on the confines of China and Thibet, sweeps across the Bay of Bengal, whence its lowest strata imbibe a quantity of moisture, moderate in amount, yet still leaving the great mass of air far below saturation. Hence it reaches Ceylon comparatively dry, and its general effects are parching and disagreeable. This character is increased as the sun recedes towards its most southern declination, and the wind acquires a more direct draught from the north; passing over the Indian peninsula and almost totally digested of humidity, it blows down the western coast of the island, and is known there by the name of the "along-shore-wind." For a time its influence is uncomfortable and its effects injurious both to health and vegetation: it warps and rends furniture, dries up the surface of the earth, and withers the delicate verdure which had sprung up during the prevalence of the previous rains. These characteristics, however, subside towards the end of the month, when the wind becomes somewhat variable with a westerly tendency and occasional showers; and the heat of the day is then partially compensated by the greater freshness of the nights. The fall of rain within the month scarcely exceeds three inches.
[Sidenote: Wind N.E. Temperature, 24 hours: Mean greatest 89° Mean least 71° Rain (inches) 2.1]
_February_ is dry and hot during the day, but the nights are cloudless and cool, and the moonlight singularly agreeable. Rain is rare, and when it occurs it falls in dashes, succeeded by damp and sultry calms. The wind is unsteady and shifts from north-east to north-west, sometimes failing entirely between noon and twilight. The quantity of rain is less than in January, and the difference of temperature between day and night is frequently as great as 15° or 20°.[1]
[Footnote 1: Dr. MACVICAR, in a paper in the _Ceylon Miscellany_, July, 1843, recorded the results of some experiments, made near Colombo, as to the daily variation of temperature and Its effects on cultivation, from which it appeared that a register thermometer, exposed on a tuft of grass in the cinnamon garden in a clear night and under the open sky, on the 2nd of January, 1841, showed in the morning that it had been so low as 52°, and when laid on the ground in the place in the sunshine on the following day, it rose to upwards of 140° Fahr.]
[Sidenote: Wind N.E. to N.W. Temperature, 24 hours: Mean greatest 87.7° Mean least 73.1° Rain (inches) 2.1]
_March_.--In March the heat continues to increase, the earth receiving more warmth than it radiates or parts with by evaporation. The day becomes oppressive, the nights unrefreshing, the grass is withered and brown, the earth hard and cleft, the lakes shrunk to shallows, and the rivers evaporated to dryness. Europeans now escape from the low country, and betake themselves to the shade of the forests adjoining the coffee-plantations in the hills; or to the still higher sanatarium of Neuera-ellia, nearly the loftiest plateau in the mountains of the Kandyan range. The winds, when any are perceptible, are faint and unsteady with a still increasing westerly tendency, partial showers sometimes fall, and thunder begins to mutter towards sunset. At the close of the month, the mean temperature will be found to have advanced about a degree, but the sensible temperature and the force of the sun's rays are felt in a still more perceptible proportion.
[Sidenote: Wind N.W. to S.W. Temperature, 24 hours: Mean greatest 88.7° Mean least 73.6° Rain (inches) 7.4]
_April_ is by far the most oppressive portion of the year for those who remain at the sea-level of the island. The temperature continues to rise as the sun in his northern progress passes vertically over the island. A mirage fills the hollows with mimic water; the heat in close apartments becomes extreme, and every living creature flies to the shade from the suffocating glare of mid-day. At length the sea exhibits symptoms of an approaching change, a ground swell sets in from the west, and the breeze towards sunset brings clouds and grateful showers. At the end of the month the mean temperature attains its greatest height during the year, being about 83° in the day, and 10° lower at night.
[Sidenote: Wind N.W. to S.W. Temperature, 24 hours: Mean greatest 87.2° Mean least 72.9° Rain (inches) 13.3]
_May_ is signalised by the great event of the change of the monsoon, and all the grand phenomena which accompany its approach.
It is difficult for any one who has not resided in the tropics to comprehend the feeling of enjoyment which accompanies these periodical commotions of the atmosphere; in Europe they would be fraught with annoyance, but in Ceylon they are welcomed with a relish proportionate to the monotony they dispel.
Long before the wished-for period arrives, the verdure produced by the previous rains becomes almost obliterated by the burning droughts of March and April. The deciduous trees shed their foliage, the plants cease to put forth fresh leaves, and all vegetable life languishes under the unwholesome heat. The grass withers on the baked and cloven earth, and red dust settles on the branches and thirsty brushwood. The insects, deprived of their accustomed food, disappear underground or hide beneath the decaying bark; the water-beetles bury themselves in the hardened mud of the pools, and the _helices_ retire into the crevices of the stones or the hollows amongst the roots of the trees, closing the apertures of their shells with the hybernating epiphragm. Butterflies are no longer seen hovering over the flowers, the birds appear fewer and less joyous, and the wild animals and crocodiles, driven by the drought from their accustomed retreats, wander through the jungle, and even venture to approach the village wells in search of water. Man equally languishes under the general exhaustion, ordinary exertion becomes distasteful, and the native Singhalese, although inured to the climate, move with lassitude and reluctance.
Meanwhile the air becomes loaded to saturation with aqueous vapour drawn up by the augmented force of evaporation acting vigorously over land and sea: the sky, instead of its brilliant blue, assumes the sullen tint of lead, and not a breath disturbs the motionless rest of the clouds that hang on the lower range of hills. At length, generally about the middle of the month, but frequently earlier, the sultry suspense is broken by the arrival of the wished-for change. The sun has by this time nearly attained his greatest northern declination, and created a torrid heat throughout the lands of southern Asia and the peninsula of India. The air, lightened by its high temperature and such watery vapour as it may contain, rises into loftier regions and is replaced by indraughts from the neighbouring sea, and thus a tendency is gradually given to the formation of a current bringing up from the south the warm humid air of the equator. The wind, therefore, which reaches Ceylon comes laden with moisture, taken up in its passage across the great Indian Ocean. As the monsoon draws near, the days become more overcast and hot, banks of clouds rise over the ocean to the west, and in the peculiar twilight the eye is attracted by the unusual whiteness of the sea-birds that sweep along the strand to seize the objects flung on shore by the rising surf.
At last the sudden lightnings flash among the hills and sheet through the clouds that overhang the sea[1], and with a crash of thunder the monsoon bursts over the thirsty land, not in showers or partial torrents, but in a wide deluge, that in the course of a few hours overtops the river banks and spreads in inundations over every level plain.
[Footnote 1: The lightnings of Ceylon are so remarkable, that in the middle ages they were as well known to the Arabian seamen, who coasted the island on their way to China, as in later times the storms that infested the Cape of Good Hope were familiar to early navigators of Portugal. In the _Mohit_ of SIDI ALI CHELEBI, translated by Von Hammer, it is stated that to seamen, sailing from Diu to Malacca, "the sign of Ceylon being near is continual lightning, be it accompanied by rain or without rain; so that 'the lightning of Ceylon' is proverbial for a liar!"--_Journ. Asiat. Soc. Beng._ v. 465.]
All the phenomena of this explosion are stupendous: thunder, as we are accustomed to be awed by it in Europe, affords but the faintest idea of its overpowering grandeur in Ceylon, and its sublimity is infinitely increased as it is faintly heard from the shore, resounding through night and darkness over the gloomy sea. The lightning, when it touches the earth where it is covered with the descending torrent, flashes into it and disappears instantaneously; but, when it strikes a drier surface, in seeking better conductors, it often opens a hollow like that formed by the explosion of a shell, and frequently leaves behind it traces of vitrification.[1] In Ceylon, however, occurrences of this kind are rare, and accidents are seldom recorded from lightning, probably owing to the profusion of trees, and especially of coco-nut palms, which, when drenched with rain, intercept the discharge, and conduct the electric matter to the earth. The rain at these periods excites the astonishment of a European: it descends in almost continuous streams, so close and so dense that the level ground, unable to absorb it sufficiently fast, is covered with one uniform sheet of water, and down the sides of acclivities it rushes in a volume that wears channels in the surface.[2] For hours together, the noise of the torrent, as it beats upon the trees and bursts upon the roofs, flowing thence in rivulets along the ground, occasions an uproar that drowns the ordinary voice, and renders sleep impossible.
[Footnote 1: See DARWIN'S _Naturalist's Voyage_, ch. iii. for an account of those vitrified siliceous tubes which are formed by lightning entering loose sand. During a thunderstorm which passed over Galle, on the 16th May, 1854, the fortifications were shaken by lightning, and an extraordinary cavity was opened behind the retaining wall of the rampart, where a hole, a yard in diameter, was carried into the ground to the depth of twenty feet, and two chambers, each six feet in length, branched out on either side at its extremity.]
[Footnote 2: One morning on awaking at Pusilawa, in the hills between Kandy and Neuera-ellia, I was taken to see the effect of a few hours' rain, during the night, on a macadamised road which I had passed the evening before. There was no symptom of a storm at sunset, and the morning was bright and cloudless; but between midnight and dawn such an inundation had swept the highway that in many places the metal had been washed over the face of the acclivity; and in one spot where a sudden bend forced the torrent to impinge against the bank, it had scooped out an excavation extending to the centre of the high road, thirteen feet in diameter, and deep enough to hold a carriage and horses.]
This violence, however, seldom lasts more than an hour or two, and gradually abates after intermittent paroxysms, and a serenely clear sky supervenes. For some days, heavy showers continue to fall at intervals in the forenoon; and the evenings which follow are embellished by sunsets of the most gorgeous splendour, lighting the fragments of clouds that survive the recent storm.
[Sidenote: Wind S.W. Temperature, 24 hours: Mean greatest 85.8° Mean least 74.4° Rain (inches) 6.8]
_June_.--The extreme heat of the previous month becomes modified in June: the winds continue steadily to blow from the south-west, and frequent showers, accompanied by lightning and thunder, serve still further to diffuse coolness throughout the atmosphere and verdure over the earth.
So instantaneous is the response of Nature to the influence of returning moisture, that, in a single day, and almost between sunset and dawn, the green hue of reviving vegetation begins to tint the saturated ground. In ponds, from which but a week before the wind blew clouds of sandy dust, the peasantry are now to be seen catching the re-animated fish; and tank-shells and water-beetles revive and wander over the submerged sedges. The electricity of the air stimulates the vegetation of the trees; and scarce a week will elapse till the plants are covered with the larvæ of butterflies, the forest murmuring with the hum of insects, and the air harmonious with the voice of birds.
The extent to which the temperature is reduced, after the first burst of the monsoon, is not to be appreciated by the indications of the thermometer alone, but is rendered still more sensible by the altered density of the air, the drier state of which is favourable to evaporation, whilst the increase of its movement bringing it more rapidly in contact with the human body, heat is more readily carried off, and the coolness of the surface proportionally increased. It occasionally happens during the month of June that the westerly wind acquires considerable strength, sometimes amounting to a moderate gale. The fishermen, at this period, seldom put to sea: their canoes are drawn far up in lines upon the shore, and vessels riding in the roads of Colombo are often driven from their anchorage and stranded on the beach.
[Sidenote: Wind S.W. Temperature, 24 hours: Mean greatest 84.8º Mean least 74.9º Rain (inches) 3.4]
_July_ resembles, to a great extent, the month which precedes it, except that, in all particulars the season is more moderate, showers are less frequent, there is less wind, and less absolute heat.

_August_.--In August the weather is charming, notwithstanding withstanding a slight increase of heat, owing to diminished evaporation; and the sun being now on its return to the equator, its power is felt in greater force on full exposure to its influence.
[Sidenote: Wind S.W. Temperature, 24 hours: Mean greatest 84.9º Mean least 74.8º Rain (inches) 5.2]
_September_.--The same atmospheric condition continues throughout September, but towards its close the sea-breeze becomes unsteady and clouds begin to collect, symptomatic of the approaching change to the north-east monsoon. The nights are always clear and delightfully cool. Rain is sometimes abundant.
[Sidenote: Wind S.W. and N.E. Temperature, 24 hours: Mean greatest 85.1º Mean least 73.3º Rain (inches) 11.2]
_October_ is more unsettled, the wind veering towards the north, with pretty frequent rain; and as the sun is now far to the southward, the heat continues to decline.
[Sidenote: Wind N.E. Temperature, 24 hours: Mean greatest 86.3º Mean least 71.5º Rain (inches) 10.7]
_November_ sees the close of the south-west monsoon and the arrival of the north-eastern. In the early part of the month the wind visits nearly every point of the compass, but shows a marked predilection for the north, generally veering from N.E. at night and early morning, to N.W. at noon; calms are frequent and precede gentle showers, and clouds form round the lower range of hills. By degrees as the sun advances in its southern declination, and warms the lower half of the great African continent, the current of heated air ascending from the equatorial belt leaves a comparative vacuum, towards which the less rarefied atmospheric fluid is drawn down from the regions north, of the tropic, bringing with it the cold and dry winds from the Himalayan Alps, and the lofty ranges of Assam. The great change is heralded as before by oppressive calms, lurid skies, vivid lightning, bursts of thunder, and tumultuous rain. But at this change of the monsoon the atmospheric disturbance is less striking than in May; the previous temperature is lower, the moisture of the air is more reduced, and the change is less agreeably perceptible from the southern breeze to the dry and parching wind from the north.
[Sidenote: Wind N.E. Temperature 24 hours: Mean greatest 85° Mean least 70° Rain (inches) 4.3]
_December_.--In December the sun attains to its greatest southern declination, and the wind setting steadily from the northeast brings with it light but frequent rains from Bay Of Bengal. The thermometer shows a maximum temperature of 85° with a minimum of 70°; the morning and the afternoon are again enjoyable in the open air, but at night every lattice that faces the north is cautiously closed against the treacherous "along-shore-wind."
Notwithstanding the violence and volume in which the rains have been here described as descending during the paroxysms of the monsoons, the total rain-fall in Ceylon is considerably less than on the continent of Throughout Hindustan the annual mean is 117.5 and on some parts on the Malabar coast, upwards of 300 inches have fallen in a single year[1]; whereas the in Ceylon rarely exceeds 80, and the highest registered in an exceptional season was 120 inches.
[Footnote 1: At Mahabaleshwar, in the Western Ghauts, the annual mean is 254 inches, and at Uttray Mullay; in Malabar, 263; whilst at Bengal it is 209 inches at Sylhet; and 610.3 at Cherraponga.]
The distribution is of course unequal, both as to time and localities, and in those districts where the fall is most considerable, the number of rainless days is the greatest.[1] An idea may be formed of the deluge that descends in Colombo during the change of the monsoon, from the fact that out of 72.4 inches, the annual average there, no less than 20.7 inches fall in April and May, and 21.9 in October and November, a quantity one-third greater than the total rain in England throughout an entire year.

In one important particular the phenomenon, of the Dekkan affords an analogy for that which presents itself in Ceylon. During the south-west monsoon the clouds are driven against the lofty chain of mountains that overhang the western shore of the peninsula, and their condensed vapour descends there in copious showers. The winds, thus early robbed of their moisture, carry but little rain to the plains of the interior, and whilst Malabar is saturated by daily showers, the sky of Coromandel is clear and serene. In the north-east monsoon a condition the very opposite exists; the wind that then prevails is much drier, and the hills which it encounters being of lower altitude, the rains are carried further towards the interior, and whilst the weather is unsettled and stormy on the eastern shore, the western is comparatively exempt, and enjoys a calm and cloudless sky.[1]
[Footnote 1: The mean of rain is, on the western side of the Dekkan, 80 inches, and on the eastern, 52.8.]
In like manner the west coast of Ceylon presents a contrast with the east, both in the volume of rain in each of the respective monsoons, and in the influence which the same monsoon exerts simultaneously on the one side of the island and on the other. The greatest quantity of rain falls on the south-western portion, in the month of May, when the wind from the Indian Ocean is intercepted, and its moisture condensed by the lofty mountain ranges, surrounding Adam's Peak. The region principally affected by it stretches from Point-de-Galle, as far north as Putlam, and eastward till it includes the greater portion of the ancient Kandyan kingdom. But the rains do not reach the opposite side of the island; whilst the west coast is deluged, the east is sometimes exhausted with dryness; and it not unfrequently happens that different aspects of the same mountain present at the same moment the opposite extremes of drought and moisture.[1]
[Footnote 1: ADMIRAL FITZROY has described, in his _Narrative of the Voyages of the Adventure and Beagle_, the striking degree in which this simultaneous dissimilarity of climate is exhibited on opposite sides of the Galapagos Islands; one aspect exposed to the south being covered with verdure and freshened with moisture, whilst all others are barren and parched.--Vol. ii. p. 502-3. The same state of things exists in the east and west sides of the Peruvian Andes, and in the mountains of Patagonia. And no more remarkable example of it exists than in the island of Socotra, east of the Straits of Bab el Mandeb, the west coast of which, during the north-east monsoon, is destitute of rain and verdure, whilst the eastern side is enriched by streams and covered by luxuriant pasturage.--_Journ. Asiat. Soc. Beng._ vol. iv. p. 141.]
One maximum at the spring change of the monsoon anticipating a little that on the West coast of India; another at the autumnal change corresponding more exactly with that of the East coast. The entire fall through the year more equably distributed at Columbo.]
On the east coast, on the other hand, the fall, during the north-east monsoon, is very similar in degree to that on the coast of Coromandel, as the mountains are lower and more remote from the sea, the clouds are carried farther inland and it rains simultaneously on both sides of the island, though much less on the west than during the other monsoon.
_The climate of Galle_, as already stated, resembles in its general characteristics that of Colombo, but, being further to the south, and more equally exposed to the influence of both the monsoons, the temperature is not quite so high; and, during the cold season, it falls some degrees lower, especially in the evening and early morning.[1]
[Footnote 1: At Point-de-Galle, in 1854, the number of rainy days was as follows:
Days. January 12 February 7 March 16 April 12 May 23 June 18 July 11 August 21 September 16 October 20 November 15 December 13]
_Kandy_, from its position, shares in the climate of the western coast; but, from the frequency of the mountain showers, and its situation, at an elevation of upwards of sixteen hundred feet above the level of the sea, it enjoys a much cooler temperature. It differs from the low country in one particular, which is very striking--the early period of the day at which the maximum heat is attained. This at Colombo is generally between two and three o'clock in the afternoon, whereas at Kandy the thermometer shows the highest temperature of the day between ten and eleven o'clock in the morning.
In the low country, ingenuity has devised so many expedients for defence from the excessive heat of the forenoon, that the languor it induces is chiefly experienced after sunset, and the coolness of the night is insufficient to compensate for the exhaustion of the day; but, in Kandy, the nights are so cool that it is seldom that warm covering can be altogether dispensed with. In the colder months, the daily range of the thermometer is considerable--approaching 30°; in the others, it differs little from 15°. The average mean, however, of each month throughout the year is nearly identical, deviating only a degree from 76°, the mean annual temperature.[1]

In all the mountain valleys, the soil being warmer than the air, vapour abounds in the early morning for the most part of the year. It greatly adds to the chilliness of travelling before dawn; but, generally speaking, it is not wetting, as it is charged with the same electricity as the surface of the earth and the human body. When seen from the heights, it is a singular object, as it lies compact and white as snow in the hollows beneath, but it is soon put in motion by the morning currents, and wafted in the direction of the coast, where it is dissipated by the sunbeams.
_Snow_ is unknown in Ceylon; _Hail_ occasionally falls in the Kandyan hills at the change of the monsoon,[1] but more frequently during that from the north-east. As observed at Kornegalle, the clouds, after collecting as usual for a few evenings, and gradually becoming more dense, advanced in a wedge-like form, with a well-defined outline. The first fall of rain was preceded by a downward blast of cold air, accompanied by hailstones which outstripped the rain in their descent. Rain and hail then poured down together, and, eventually, the latter only spread its deluge far and wide, In 1852, the hail which thus fell at Kornegalle was of such a size that half-a-dozen lumps filled a tumbler, In shape, they were oval and compressed, but the mass appeared to have formed an hexagonal pyramid, the base of which was two inches in diameter, and about half-an-inch thick, gradually thinning towards the edge. They were tolerably solid internally, each containing about the size of a pea of clear ice at the centre, but the sides and angles were spongy and flocculent, as if the particles had been driven together by the force of the wind, and had coalesced at the instant of contact. A phenomenon so striking as the fall of ice, at the moment of the most intense atmospherical heat, naturally attracts the wonder of the natives, who hasten to collect the pieces, and preserve them, when dissolved, in bottles, from a belief in their medicinal properties. Mr. Morris, who has repeatedly observed hailstones in the Seven Korles, is under the impression that their occurrence always happens at the first outburst of the monsoon, and that they fall at the moment, which is marked by the first flash of lightning.
[Footnote 1: It is stated in the _Physical Atlas_ of KEITH JOHNSTON, that hail in India has not been noticed south of Madras. But in Ceylon it has fallen very recently at Korngalle, at Badulla, at Kaduganawa; and I have heard of a hail storm at Jaffna. On 1 the 24th of Sept. 1857, during a thunder-storm, hail fell near Matelle in such quantity that in places it formed drifts upwards of a foot in depth.]
According to Professor Stevelly, of Belfast, the rationale of their appearance on such occasions seems to be that, on the sudden formation and descent of the first drops, the air expanding and rushing into the void spaces, robs the succeeding drops of their caloric so effectually as to send them to the earth frozen into ice-balls.
These descriptions, it will be observed, apply exclusively to the southern regions on the east and west of Ceylon; and, in many particulars, they are inapplicable to the northern portions of the island. At Trincomalie, the climate bears a general resemblance to that of the Indian peninsula south of Madras: showers are frequent, but light, and the rain throughout the year does not exceed forty inches. With moist winds and plentiful dew, this sustains a vigorous vegetation near the coast; but in the interior it would be insufficient for the culture of grain, were not the water husbanded in tanks; and, for this reason, the bulk of the population are settled along the banks of the great rivers.
The temperature of this part of Ceylon follows the course of the sun, and ranges from a minimum of 70° in December and January, to a maximum of 94° in May and June; but the heat is rendered tolerable at all seasons by the steadiness of the land and sea breezes.[1]
[Footnote 1: The following facts regarding the climate of Trincomalie have been, arranged from elaborate returns furnished by Mr. Higgs, the master-attendant of the port, and published under the authority of the meteorological department of the Board of Trade:--

In the extreme north of the island, the peninsula of Jaffna, and the vast plains of Neura-kalawa and the Wanny, form a third climatic division, which, from the geological structure and peculiar configuration of the district, differs essentially from the rest of Ceylon. This region, which is destitute of mountains, is undulating in a very slight degree; the dry and parching north-east wind desiccates the soil in its passage, and the sandy plains are covered with a low and scanty vegetation, chiefly fed by the night dews and whatever moisture is brought by the on-shore wind. The total rain of the year does not exceed thirty inches; and the inhabitants live in frequent apprehension of droughts and famines. These conditions attain their utmost manifestation at the extreme north and in the Jaffna peninsula: there the temperature is the highest[1] in the island, and, owing to the humidity of the situation and the total absence of hills, it is but little affected by the changes of the monsoons; and the thermometer keeps a regulated pace with the progress of the sun to and from the solstices. The soil, except in particular spots, is porous and sandy, formed from the detritus of the coral rocks which it overlays. It is subject to droughts sometimes of a whole year's continuance; and rain, when it falls, is so speedily absorbed, that it renders but slight service to cultivation, which is entirely carried on by means of tanks and artificial irrigation, in the practice of which the Tamil population of this district exhibits singular perseverance and ingenuity.[2] In the dry season, when scarcely any verdure is discernible above ground, the sheep and goats feed on their knees--scraping away the sand, in order to reach the wiry and succulent roots of the grasses. From the constancy of this practice horny callosities are produced, by which these hardy creatures may be distinguished.
[Footnote 1: The mean lowest temperature at Jaffna is 70º, the mean highest 90º; but in 1845-6 the thermometer rose to 90º and 100º.]
[Footnote 2: For an account of the Jaffna wells, and the theory of their supply with fresh water, see ch. i. p. 21.]
Water-spouts are frequent on the coast of Ceylon, owing to the different temperature of the currents of air passing across the heated earth and the cooler sea, but instances are very rare of their bursting over land, or of accidents in consequence.[1]
[Footnote 1: CAMOENS, who had opportunities of observing the phenomena of these seas during his service on board the fleet of Cabral, off the coast of Malabar and Ceylon, has introduced into the _Lusiad_ the episode of a water-spout in the Indian Ocean; but, under the belief that the water which descends had been previously drawn up by suction from the ocean, he exclaims:--
"But say, ye sages, who can weigh the cause,
And trace the secret springs of Nature's laws;
Say why the wave, of bitter brine erewhile,
Should be the bosom of the deep recoil,
Robbed of its salt, and from the cloud distil,
Sweet as the waters of the limpid rill?"
(Book v.)
But the truth appears to be that the torrent which descends from a water-spout, is but the condensed accumulation of its own vapour, and, though in the hollow of the lower cone which rests upon the surface of the sea, salt water may possibly ascend in the partial vacuum caused by revolution; or spray may be caught up and collected by the wind, still these cannot be raised by it beyond a very limited height, and what Camoens saw descend was, as he truly says, the sweet water distilled from the cloud.]
A curious phenomenon, to which the name of "anthelia" has been given, and which may probably have suggested to the early painters the idea of the glory surrounding the heads of beatified saints, is to be seen in singular beauty, at early morning, in Ceylon. When the light is intense, and the shadows proportionally dark--when the sun is near the horizon, and the shadow of a person walking is thrown on the dewy grass--each particle of dew furnishes a double reflection from its concave and convex surfaces; and to the spectator his own figure, but more particularly the head, appears surrounded by a halo as vivid as if radiated from diamonds.[1] The Buddhists may possibly have taken from this beautiful object their idea of the _agni_ or emblem of the sun, with which the head of Buddha is surmounted. But unable to express a _halo_ in sculpture, they concentrated it into a _flame_.
[Footnote 1: SCORESBY describes the occurrence of a similar phenomenon in the Arctic Seas in July, 1813, the luminous circle being produced on the particles of fog which rested on the calm water. "The lower part of the circle descended beneath my feet to the side of the ship, and although it could not be a hundred feet from the eye, it was perfect, and the colours distinct. The centre of the coloured circle was distinguished by my own shadow, the head of which, enveloped by a halo, was most conspicuously pourtrayed. The halo or glory evidently impressed on the fog, but the figure appeared to be a shadow on the water; the different parts became obscure in proportion to their remoteness from the head, so that the lower extremities were not perceptible."--_Account of the Arctic Regions_, vol. i. ch. v. sec. vi. p. 394. A similar phenomenon occurs in the Khasia Hills, in the north-east of Bengal.--_Asiat. Soc. Journ. Beng._ vol. xiii. p. 616.]
Another luminous phenomenon which sometimes appears in the hill country, consists of beams of light, which intersect the sky, whilst the sun is yet in the ascendant; sometimes horizontally, accompanied by intermitting movements, and sometimes vertically, a broad belt of the blue sky interposing between them.[1]
[Footnote 1: VIGNE mentions an appearance of this kind in the valley of Kashmir: "Whilst the rest of the horizon was glowing golden over the mountain tops, a broad well-defined ray-shaped streak of indigo was shooting upwards in the zenith: it remained nearly stationary about an hour, and was then blended into the sky around it, and disappeared with the day. It was, no doubt, owing to the presence of some particular mountains which intercepted the red rays, and threw a blue shadow, by causing so much of the sky above Kashmir to remain unaffected by them."--_Travels in Kashmir_, vol. ii. ch. x. p. 115.]
In Ceylon this is doubtless owing to the air holding in suspension a large quantity of vapour, which receives shadows and reflects rays of light. The natives, who designate them "Buddha's rays," attach a superstitious dread to their appearance, and believe them to be portentous of misfortune--in every month, with the exception of _May_, which, for some unexplained reason, is exempted.
