1: For the particulars of this singular well, see Vol. II. Pt. IX. ch. vi. p. 536.

A similar subterranean stream is said to conduct to the sea from another singular well near Tillipalli, in sinking which the workmen, at the depth of fourteen feet, came to the ubiquitous coral, the crust of which gave way, and showed a cavern below containing the water they were in search of, with a depth of more than thirty-three feet. It is remarkable that the well at Tillipalli preserves its depth at all seasons alike, uninfluenced by rains or drought; and a steam-engine erected at Potoor, with the intention of irrigating the surrounding lands, failed to lower it in any perceptible degree.

Other wells, especially some near the coast, maintain their level with such uniformity as to be inexhaustible at any season, even after a succession of years of drought—a fact from which it may fairly be inferred that their supply is chiefly derived by percolation from the sea.[1]

1: DARWIN, in his admirable account of the coral formations of the Pacific and Indian oceans, has propounded a theory as to the abundance of fresh water in the atolls and islands on coral reefs, furnished by wells which ebb and flow with the tides. Assuming it to be impossible to separate salt from sea water by filtration, he suggests that the porous coral rock being permeated by salt water, the rain which falls on the surface must sink to the level of the surrounding sea, "and must accumulate there, displacing an equal bulk of sea water—and as the portion of the latter in the lower part of the great sponge-like mass rises and falls with the tides, so will the fresh water near the surface."—Naturalist's Journal, ch. xx. But subsequent experiments have demonstrated that the idea of separating the salt by filtration is not altogether imaginary; as Darwin seems to have then supposed; and Mr. WITT, in a remarkable paperOn a peculiar power possessed by Porous Media of removing matters from solution in water, has since succeeded in showing that "water containing considerable quantities of saline matter in solution may, by merely percolating through great masses of porous strata during long periods, be gradually deprived of its saltsto such an extent as probably to render even sea-water fresh."—Philos. Mag., 1856. Divesting the subject therefore of this difficulty, other doubts would appear to suggest themselves as to the applicability of Darwin's theory to coral formations in general. For instance, it might be supposed that rain falling on a substance already saturated with moisture, would flow off instead of sinking into it; and that being of less specific gravity than salt water, it would fail to "displace an equal bulk" of the latter. There are some extraordinary but well attested statements of a thin layer of fresh water being found on the surface of the sea, after heavy rains in the Bay of Bengal. (Journ. Asiat. Soc. Beng. vol. v. p. 239.) Besides, I fancy that in the majority of atolls and coral islands the quantity of rain which so small an area is calculated to intercept would be insufficient of itself to account for the extraordinary abundance of fresh water daily drawn from the wells. For instance, the superficial extent of each of the Laccadives is but two or three square miles, the surface soil resting on a crust of coral, beneath which is a stratum of sand; and yet on reaching the latter, fresh water flows in such profusion, that wells and large tanks for soaking coco-nut fibre are formed in any place by merely "breaking through the crust and taking out the sand."—Madras Journal, vol. xiv. It is curious that the abundant supply of water in these wells should have attracted the attention of the early navigators, and Cosmas Indicoplenstes, writing in the sixth century, speaks of the numerous small islands off the coast of Taprobane, with abundance of fresh water and coco-nut palms, although these islands rest on a bed of sand. (Cosmas Ind. ed. Thevenot, vol. i. p. 3, 20). It is remarkable that in the little island of Ramisseram, one of the chain which connects Adam's Bridge with the Indian continent, fresh water is found freely on sinking for it in the sand. But this is not the case in the adjacent island of Manaar, which participates in the geologic character of the interior of Ceylon. The fresh water in the Laccadive wells always fluctuates with the rise and fall of the tides. In some rare instances, as on the little island of Bitra, which is the smallest inhabited spot in the group, the water, though abundant, is brackish, but this is susceptible of an explanation quite consistent with the experiments of Mr. Witt, which require that the process of percolation shall be continued "duringlongperiods and throughgreat masses of porous strata;" Darwin equally concedes that to keep the rain fresh when banked in, as he assumes, by the sea, the mass of madrepore must be "sufficiently thick to prevent mechanical admixture; and where the land consists of loose blocks of coral with open interstices, the water, if a well be dug, is brackish." Conditions analogous to all these particularised, present themselves at Jaffna, and seem to indicate that the extent to which fresh water is found there, is directly connected with percolation from the sea. The quantity of rain which annually falls is less than in England, being but thirty inches; whilst the average heat is highest in Ceylon, and the evaporation great in proportion. Throughout the peninsula, I am informed by Mr. Byrne, the Government surveyor of the district, that as a general rule "all the wells are below the sea level." It would be useless to sink them in the higher ground, where they could only catch surface water. The November rains fill them at once to the brim, but the water quickly subsides as the season becomes dry, and "sinks to the uniform level, at which it remains fixed for the next nine or ten months, unless when slightly affected by showers." "No well below the sea level becomes dry of itself," even in seasons of extreme and continued drought. But the contents do not vary with the tides, the rise of which is so trifling that the distance from the ocean, and the slowness of filtration, renders its fluctuations imperceptible.On the other hand, the well of Potoor, the phenomena of which indicate its direct connection with the sea, by means of a fissure or a channel beneath the arch of magnesian limestone, rises and falls a few inches in the course of every twelve hours. Another well at Navokeiry, a short distance from it, does the same, whilst the well at Tillipalli is entirely unaffected as to its level by any rains, and exhibits no alteration of its depths on either monsoon. ADMIRAL FITZROY, in hisNarrative of the Surveying Voyages of the Adventure and Beagle, the expedition to which Mr. Darwin was attached, adverts to the phenomenon in connection with the fresh water found in the Coral Islands, and the rise and fall of the wells, and the flow and ebb of the tide. He advances the theory propounded by Darwin of the retention of the river-water, which he says, "does not mix with the salt water which surrounds it except at the edges of the land. The flowing tide pushes on every side, the mixed soil being very porous, and causes the water to rise: when the tide falls, the fresh water sinks also.A sponge full of fresh water placed gently in a basin of salt water, will not part with its contents for a length of time if left untouched, and the water in the middle of the sponge will be found untainted by salt for many days: perhaps much longer if tried."—Vol. i. p. 365. In a perfectly motionless medium the experiment of the sponge may no doubt be successful to the extent mentioned by Admiral Fitzroy; and so the rain-water imbibed by a coral rock might for a length of time remain fresh where it came into no contact with the salt. But the disturbance caused by the tides, and the partial intermixture admitted by Admiral Fitzroy, must by reiterated occurrence tend in time to taint the fresh water which is affected by the movement: and this is demonstrable even by the test of the sponge; for I find that on charging one with coloured fluid, and immersing it in a vessel containing water perfectly pure, no intermixture takes place so long as the pure water is undisturbed; but on causing an artificial tide, by gradually withdrawing and as gradually replacing a portion of the surrounding contents of the basin, the tinted water in the sponge becomes displaced and disturbed, and in the course of a few ebbs and flows its escape is made manifest by the quantity of colour which it imparts to the surrounding fluid.

An idea of the general aspect of Ceylon will be formed from what has here been described. Nearly four parts of the island are undulating plains, slightly diversifiedby offsets from the mountain system which entirely covers the remaining fifth. Every district, from the depths of the valleys to the summits of the highest hills, is clothed with perennial foliage; and even the sand-drifts, to the ripple on the sea line, are carpetedwith verdure, and sheltered from the sunbeams by the cool shadows of the palm groves.

SOIL.—But the soil, notwithstanding this wonderful display of spontaneous vegetation, is not responsive to systematic cultivation, and is but imperfectly adapted for maturing a constant succession of seeds and cereal productions.[1] Hence arose the disappointment which beset the earliest adventurers who opened plantations of coffee in the hills, on discovering that after the first rapid development of the plants, delicacy and languor ensued, which were only to be corrected by returning to the earth, in the form of manures, those elements with which it had originally been but sparingly supplied, and which were soon exhausted by the first experiments in cultivation.

1: See a paper in the Journal of Agriculture, for March, 1857, Edin.: onTropical Cultivation and its Limits, by Dr. MACVICAR.

Patenas.—The only spots hitherto found suitable for planting coffee, are those covered by the ancient forests of the mountain zone; and one of the most remarkable phenomena in the oeconomic history of the island, is the fact that the grass lands on the same hills, closely adjoining the forests and separated from them by no visible line save the growth of the trees, although they seem to be identical in the nature of the soil, have hitherto proved to be utterly insusceptible of reclamation or culture by the coffee planter.[1] These verdant openings, to which the natives have given the name ofpatenas, generally occur about the middle elevation of the hills, the summits and the hollows being covered with the customary growth of timber trees, which also fringe the edges of the mountain streams that trickle down these park-like openings. The forest approaches boldly to the very edge of a "patena," not disappearinggradually or sinking into a growth of underwood, but stopping abruptly and at once, the tallest trees forming a fence around the avoided spot, as if they enclosed an area of solid stone. These sunny expanses vary in width from a few yards to many thousands of acres; in the lower ranges of the hills they are covered with tall lemon-grass(Andropogon schoenanthus)of which the oppressive perfume and coarse texture, when full grown, render it distasteful to cattle, which will only crop the delicate braird that springs after the surface has been annually burnt by the Kandyans. Two stunted trees, alone, are seen to thrive in these extraordinary prairies,Careya arboreaandEmblica officinalis, and these only below an altitude of 4000 feet; above this, the lemon-grass is superseded by harder and more wiry species; but the earth is still the same, a mixture of decomposed quartz largely impregnated with oxide of iron, but wanting the phosphates and other salts which are essential to highly organised vegetation.[2] The extent of the patena land is enormous in Ceylon, amounting to millions of acres; and it is to be hoped that the complaints which have hitherto been made by the experimental cultivators of coffee in the Kandyan provinces may hereafter prove exaggerated, and that much that has been attributed to the poverty of the soil may eventually be traced to deficiency of skill on the part of the early planters.

1: Since the above was written, attempts have been made, chiefly by natives to plant coffee on patena land. The result is a conviction that the cultivation is practicable, by the use of manures from the beginning; whereas forest land is capable, for three or four years at least, of yielding coffee without any artificial enrichment of the soil.2: HUMBOLDT is disposed to ascribe the absence of trees in the vast grassy plains of South America, to "the destructive custom of setting fire to the woods, when the natives want to convert the soil into pasture: when during the lapse of centuries grasses and plants have covered the surface with a carpet, the seeds of trees can no longer germinate and fix themselves in the earth, although birds and winds carry them continually from the distant forests into the Savannahs."—Narrative, vol. i. ch. vi. p. 242.

The natives in the same lofty localities find no deficient returns in the crops of rice, which they raise in the ravines and hollows, into which the earth from above has been washed by the periodical rains; but the cultivation of rice is so entirely dependent on thepresence of water, that no inference can be fairly drawn as to the quality of the soil from the abundance of its harvest.

The fields on which rice is grown in these mountains form one of the most picturesque and beautiful objects in the country of the Kandyans. Selecting an angular recess where two hills converge, they construct a series of terraces, raised stage above stage, and retiring as they ascend along the slope of the acclivity, up which they are carried as high as the soil extends.[1] Each terrace is furnished with a low ledge in front, behind which the requisite depth of water is retained during the germination of the seed, and what is superfluous is permitted to trickle down to the one below it. In order to carry on this peculiar cultivation the streams are led along the level of the hills, often from a distance of many miles, with a skill and perseverance for which the natives of these mountains have attained a great renown.

1: The conversion of the land into these hanging farms is known in Ceylon as "assuedamizing," a term borrowed from the Kandyan vernacular, in which the word "assuedamé" implies the process above described.

In the lowlands to the south, the soil partakes of the character of the hills from whose detritus it is to a great extent formed. In it rice is the chief article produced, and for its cultivation the disintegrated laterite (cabook), when thoroughly irrigated, is sufficiently adapted. The seed time in the southern section of the island is dependent on the arrival of the rains in November and May, and hence the mountains and the maritime districts at their base enjoy two harvests in each year—theMaha, which is sown about July and August, and reaped in December and January, theYallawhich is sown in spring, and reaped from the 15th of July to the 20th September. But owing to the different description of seed sown in particular localites, and the extent to which they arerespectively affected by the rains, the times of sowing and harvest vary considerably on different sides of the island.[1]

1: The reaping of other descriptions of grain besides rice occurs at various periods of the year according to the locality.

In the north, where the influence of the monsoons is felt with less force and regularity, and where, to counteract their uncertainty, the rain is collected in reservoirs, a wider discretion is left to the husbandman in the choice of season for his operations.[1] Two crops of grain, however, are the utmost that is taken from the land, and in many instances only one. The soil near the coast is light and sandy, but in the great central districts of Neuera-kalawa and the Wanny, there is found in the midst of the forests a dark vegetable mould, in which in former times rice was abundantly grown by the aid of those prodigious artificial works for irrigation which still form one of the wonders of the island. Many of the tanks, though partially in ruins, cover an area from ten to fifteen miles in circumference. They are now generally broken and decayed; the waters which would fertilise a province are allowed to waste themselves in the sands, and hundreds of square miles capable of furnishing food for all the inhabitants of Ceylon are abandoned to solitude and malaria, whilst rice for the support of the non-agricultural population is annually imported from the opposite coast of India.

1: This peculiarity of the north of Ceylon was noticed by the Chinese traveller FA HIAN, who visited the island in the fourth century, and says of the country around Anarajapoora: "L'ensemencement des champs est suivant la volonté des gens; il n'y a point de temps pour cela."—Foĕ Kouĕ Ki; p. 332.

Talawas.—In these districts of the lowlands, especially on the eastern coast of the island, and in the country watered by the Mahawelli-ganga and the other great rivers which flow towards the Bay of Bengal and the magnificent estuary of Trincomalie, there are open glades which diversify the forest scenery somewhatresembling the grassy patenas in the hills, but differing from them in the character of their soil and vegetation. These park-like meadows, or, as the natives call them, "talawas," vary in extent from one to a thousand acres. They are belted by the surrounding woods, and studded with groups of timber and sometimes with single trees of majestic dimensions. Through these pastures the deer troop in herds within gunshot, bounding into the nearest cover when disturbed.

Lower still and immediately adjoining the sea-coast, the broken forest gives place to brushwood, with here and there an assemblage of dwarf shrubs; but as far as the eye can reach, there is one vast level of impenetrable jungle, broken only by the long sweep of salt marshes which form lakes in the rainy season, but are dry between the monsoons, and crusted with crystals that glitter like snow in the sunshine.

On the western side of the island the rivers have formed broad alluvial plains, in which the Dutch attempted to grow sugar. The experiment has been often resumed since; but even here the soil is so defective, that the cost of artificially enriching it has hitherto been a serious obstruction to success commercially, although in one or two instances, plantations on a small scale have succeeded to a certain extent.

METALS.—The plutonic rocks of Ceylon are but slightly metalliferous, and hitherto their veins and deposits have been but imperfectly examined. The first successful survey attempted by the Government was undertaken during the administration of Viscount Torrington, who, in 1847, commissioned Dr. Gygax to proceed to the hill district south of Adam's Peak, and furnish a report on its products. His investigations extended from Ratnapoora, in a south-eastward direction, to the mountains which overhang Bintenne, but the results obtained did not greatly enlarge the knowledge previously possessed. He established the existenceoftinin the alluvium along the base of the mountains to the eastward towards Edelgashena; but so circumstanced, owing to the flow of the Walleway river, that, without lowering its level, the metal could not be extracted with advantage. The position in which it occurs is similar to that in which tin ore presents itself in Saxony; and along with it, the natives, when searching for gems, discover garnets, corundum, white topazes, zircon, and tourmaline.

Goldis found in minute particles at Gettyhedra, and in the beds of the Maha Oya and other rivers flowing towards the west.[1] But the quantity hitherto discovered has been too trivial to reward the search. The early inhabitants of the island were not ignorant of its presence; but its occurrence on a memorable occasion, as well as that of silver and copper, is recorded in the Mahawanso as a miraculous manifestation, which signalised the founding of one of the most renowned shrines at the ancient capital.[2]

1: Ruanwellé, a fort about forty miles distant from Colombo, derives its name from the sands of the river which flows below it,—rang-welle, "golden sand." "Rang-galla," in the central province, is referable to the same root—the rock of gold.2:Mahawanso,ch. xxiii. p. 166, 167.

Nickelandcobaltappear in small quantities in Saffragam, and the latter, together withrutile(an oxide of titanium) andwolfram, might find a market in China for the colouring of porcelain.[1]Tellurium, another rare and valuable metal, hitherto found only in Transylvania and the Ural, has likewise been discovered in thesemountains,Manganeseis abundant, andIronoccurs in the form of magnetic iron ore, titanite, chromate, yellow hydrated, per-oxide and iron pyrites. In most of these, however, the metal is scanty, and the ores of little comparative value, except for the extraction of manganese and chrome. "But there is another description of iron ore," says Dr. Gygax, in his official report to the Ceylon Government, "which is found in vast abundance, brown and compact, generally in the state of carbonate, though still blended with a little chrome, and often molybdena. It occurs in large masses and veins, one of which extends for a distance of fifteen miles; from it millions of tons might be smelted, and when found adjacent to fuel and water-carriage, it might be worked to a profit. The quality of the iron ore found in Ceylon is singularly fine; it is easily smelted, and so pure when reduced as to resemble silver. The rough ore produces fromthirtytoseventy-fiveper cent., and on an average fullyfifty. The iron wrought from it requires no puddling, and, converted into steel, it cuts like a diamond. The metal could be laid down in Colombo at £6 per ton, even supposing the ore to be brought thither for smelting, and prepared with English coal; butanthracitebeing found upon the spot, it could be used in the proportion of three to one of the British coal; and the cost correspondingly reduced."

Remains of ancient furnaces are met with in all directions precisely similar to those still in use amongst the natives. The Singhalese obtain the ore they require without the trouble of mining; seeking a spot where the soil has been loosened by the latest rains, they break off a sufficient quantity, which, in less than three hours, they convert into iron by the simplest possible means. None of their furnaces are capable of smelting more than twenty pounds of ore, and yet this quantity yields from seven to ten pounds of good metal.

Theanthracitealluded to by Dr. Gygax is found inthe southern range of hills near Nambepane, in close proximity to rich veins ofplumbago, which are largely worked in the same district, and the quantity of the latter annually exported from Ceylon exceeds a thousand tons.Molybdenais found in profusion dispersed through many rocks in Saffragam, and it occurs in the alluvium in grey scales, so nearly resembling plumbago as to be commonly mistaken for it.Kaolin, called by the nativesKirimattie, appears at Neuera-ellia at Hewahette, Kaduganawa, and in many of the higher ranges as well as in the low country near Colombo; its colour is so clear as to suit for the manufacture of porcelain[1]; but the difficulty and cost of carriage render it as yet unavailing for commerce, and the only use to which it has hitherto been applied is to serve for whitewash instead of lime.

Nitrehas long been known to exist in Ceylon, where the localities in which it occurs are similar to those in Brazil. In Saffragam alone there are upwards of sixty caverns known to the natives, from which it may be extracted, and others exist in various parts of the island, where the abundance of wood to assist in its lixiviation would render that process easy and profitable. Yet so sparingly has this been hitherto attempted, that even for purposes of refrigeration, crude saltpetre is still imported from India.[1]

1: The mineralogy of Ceylon has hitherto undergone no scientific scrutiny, nor have its mineral productions been arranged in any systematic and comprehensive catalogue. Specimens are to be found in abundance in the hands of native dealers; but from indifference or caution they express their inability to afford adequate information as to their locality, their geological position, or even to show with sufficient certainty that they belong to the island. Dr. Gygax, as the results of some years spent in exploring different districts previous to 1847, was enabled to furnish a list of but thirty-seven species, the site of which he had determined by personal inspection.

GEMS.—But the chief interest which attaches to themountains and rocks of this region, arises from the fact that they contain those mines ofprecious stoneswhich from time immemorial have conferred renown on Ceylon. The ancients celebrated the gems as well as the pearls of "Taprobane;" the tales of mariners returning from their eastern expeditions supplied to the story-tellers of the Arabian Nights their fables of the jewels of "Serendib;" and the travellers of the Middle Ages, on returning to Europe, told of the "sapphires, topazes, amethysts, garnets, and other costly stones" of Ceylon, and of the ruby which belonged tothe king of the island, "a span in length, without a flaw, and brilliant beyond description."[1]

1:Travels ofMARCO POLO,a Venetian, in the Thirteenth Century, Lond. 1818.

The extent to which gems are still found is sufficient to account for the early traditions of their splendour and profusion; and fabulous as this story of the ruby of the Kandyan kings may be, the abundance of gems in Saffragam has given to the capital of the district the name ofRatnapoora, which means literally "the city of rubies."[1] They are not, however, confined to this quarter alone, but quantities are still found on the western plains between Adam's Peak and the sea, at Neuera-ellia, in Oovah, at Kandy, at Mattelle in the central province, and at Ruanwelli near Colombo, at Matura, and in the beds of the rivers eastwards towards the ancient Mahagam.

1: In the vicinity of Ratnapoora there are to be obtained masses of quartz of the most delicate rose colour. Some pieces, which were brought to me in Colombo, were of extraordinary beauty; and I have reason to believe that it can be obtained in pieces large enough to be used as slabs for tables, or formed into vases and columns, I may observe that similar pieces are to be found in the south of Ireland, near Cork.

But the localities which chiefly supply the Ceylon gems are the alluvial plains at the foot of the stupendous hills of Saffragam, in which the detritus of the rocks has been carried down and intercepted by the slight elevations that rise at some distance from the base of the mountains. The most remarkable of these gem-bearing deposits is in the flat country around Ballangodde, south-east of Ratnapoora; but almost every valley in communication with the rocks of the higher ranges contains stones of more or less value, and the beds of the rivers flowing southward from the mountain chain are so rich in comminuted fragments of rubies, sapphires, and garnets[1], that their sands insome places are used by lapidaries in polishing the softer stones, and in sawing the elephants' grinders into plates. The cook of a government officer at Galle recently brought to him a ruby about the size of a small pea, which he had taken from the crop of a fowl.

1: Mr. BAKER, in a work entitledThe Rifle and the Hound in Ceylon, thus describes the sands of the Manic Ganga, near the ruins of Mahagam, in the south-eastern extremity of the island:—"The sand was composed of mica, quartz, sapphire, ruby, and jacinth; but the large proportion of ruby sand was so extraordinary that it seemed to rival Sinbad's story of the vale of gems. The whole of this was valueless, but the appearance of the sand was very inviting, as the shallow stream in rippling over it magnified the tiny gems into stones of some magnitude. I passed an hour in vainly searching for a ruby worth collecting, but the largest did not exceed the size of a mustard seed."—BAKER'SRifle and Hound in Ceylon, p. 181.

Of late years considerable energy has been shown by those engaged in the search for gems; neglected districts have been explored, and new fields have been opened up at such places as Karangodde and Weraloopa, whence stones have been taken of unusual size and value.

It is not, however, in the recent strata of gravel, nor in those now in process of formation, that the natives search for gems. They penetrate these to the depth of from ten to twenty feet, in order to reach a lower deposit distinguished by the name ofNellan, in which the objects of their search are found. This is of so early a formation that it underlies the present beds of rivers, and is generally separated from them or from the superincumbent gravel by a hard crust (calledKadua), a few inches in thickness, and so consolidated as to have somewhat the appearance of laterite, or of sun-burnt brick. The nellan is for the most part horizontal, but occasionally it is raised into an incline as it approaches the base of the hills. It appears to have been deposited previous to the eruption of the basalt, on which in some places it reclines, and to have undergone some alteration from the contact. It consists of water-worn pebbles firmly imbedded in clay, and occasionally there occur large lumps of granite and gneiss, in the hollows under which, as well as in "pockets" in the clay (which from their shape the natives denominate"elephants' footsteps") gems are frequently found in groups as if washed in by the current.

The persons who devote themselves to this uncertain pursuit are chiefly Singhalese, and the season selected by them for "gemming" is between December and March, when the waters are low.[1] The poorer and least enterprising adventurers betake themselves to the beds of streams, but the most certain though the most costly course is to sink pits in the adjacent plains, which are consequently indented with such traces of recent explorers. The upper gravel is pierced, the covering crust is reached and broken through, and the nellan being shovelled into conical baskets and washed to free it from the sand, the residue is carefully searched for whatever rounded crystals and minute gems it may contain.

1: A very interesting account ofGems and Gem Searching, by Mr. WM. STEWART, appeared in theColombo Observerfor June, 1855.

It is strongly characteristic of the want of energy in the Singhalese, that although for centuries those alluvial plains and watercourses have been searched without ceasing, no attempt appears to have been made to explore the rocks themselves, in the debris of which the gems have been brought down by the rivers. Dr. Gygax says: "I found at Hima Pohura, on the south-eastern decline of the Pettigalle-Kanda, about the middle of the descent, a stratum of grey granite containing, with iron pyrites and molybdena, innumerable rubies from one-tenth to a fourth of an inch in diameter, and of a fine rose colour, but split and falling to powder. It is not an isolated bed of minerals, but a regular stratum extending probably to the same depth and distance as the other granite formations. I followed it as far as was practicable for close examination, but everywhere in the lower part of the valley I found it so decomposed that the hammer sunk in the rock, and even bamboos were growing on it. On the higher ground near somesmall round hills which intercept it, I found the rubies changed into brown corundum. Upon the hills themselves the trace was lost, and instead of a stratum there was merely a wild chaos of blocks of yellow granite. I carefully examined all the minerals which this stratum contains,—felspar, mica, and quartz molybdena, and iron pyrites,—and I found all similar to those I had previously got adhering to rough rubies offered for sale at Colombo.I firmly believe that in such strata the rubies of Ceylon are originally found, and that those in the white and blue clay at Ballangodde and Ratnapoora are but secondary deposits. I am further inclined to believe that these extend over the whole island, although often intercepted and changed in their direction by the rising of the yellow granite." It is highly probable that the finest rubies are to be found in them, perfect and unchanged by decomposition; and that they are to be obtained by opening a regular mine in the rock like the ruby mine of Badakshan in Bactria described by Sir Alexander Burnes. Dr. Gygax adds that having often received the minerals of this stratum with the crystals perfect, he has reason to believe that places are known to the natives where such mines might be opened with confidence of success.

Rubies both crystalline and amorphous are also found in a particular stratum of dolomite at Bullatotte and Badulla, in which there is a peculiar copper-coloured mica with metallic lustre.Star rubies, the "asteria" of Pliny (so called from their containing a movable six-rayed star), are to be had at Ratnapoora and for very trifling sums. The blue tinge which detracts from the value of the pure ruby, whose colour should resemble "pigeon's blood," is removed by the Singhalese, by enveloping the stone in the lime of a calcined shell and exposing it to a high heat.Spinelof extremely beautiful colours is found in the bed of the Mahawelli-ganga at Kandy, and from the locality it has obtained the name ofCandite.

It is strange that although thesapphireis found in all this region in greater quantity than the ruby, it has never yet been discovered in the original matrix, and the small fragments which sometimes occur in dolomite show that there it is but a deposit. From its exquisite colour and the size in which it is commonly found, it forms by far the most valuable gem of the island. A piece which was dug out of the alluvium within a few miles of Ratnapoora in 1853, was purchased by a Moor at Colombo, in whose hands it was valued at upwards of four thousand pounds.

The original site of theoriental topazis equally unknown with that of the sapphire. The Singhalese rightly believe them to be the same stone only differing in colour, and crystals are said to be obtained with one portion yellow and the other blue.

Garnetsof inferior quality are common in the gneiss, but finer ones are found in the hornblende rocks.

Cinnamon-stone(which is properly a variety of garnet) is so extremely abundant, that vast rocks containing it in profusion exist in many places, especially in the alluvium around Matura; and at Belligam, a few miles east from Point-de-Galle, a vast detached rock is so largely composed of cinnamon-stones that it is carried off in lumps for the purpose of extracting and polishing them.

TheCat's-eyeis one of the jewels of which the Singhalese are especially proud, from a belief that it is only found in their island; but in this I apprehend they are misinformed, as specimens of equal merit have been brought from Quilon and Cochin on the southern coast of Hindostan. The cat's-eye is a greenish translucent quartz, and when cuten cabochonit presents a moving internal reflection which is ascribed to the presence of filaments of asbestos. Its perfection is estimated by the natives in proportion to the narrowness and sharpness of the ray and the pure olive-tint of the ground over which it plays.

Amethystsare found in the gneiss, and some discoloured though beautiful specimens in syenite; they are too common to be highly esteemed. The "Matura Diamonds," which are largely used by the native jewellers, consist of zircon, found in the syenite not only uncoloured, but also of pink and yellow tints, the former passing for rubies.

But one of the prettiest though commonest gems in the island is the "Moon-stone," a variety of pearly adularia presenting chatoyant rays when simply polished. They are so abundant that the finest specimens may be bought for a few shillings. These, withaqua marina, a bad description ofopal rock crystalin extremely large pieces,tourmaline, and a number of others of no great value, compose the list of native gems procurable in Ceylon.[1] Diamonds, emeralds, agates, carnelians, opal and turquoise, when they are exhibited by the natives, have all been imported from India.

1: Caswini and some of the Arabian geographers assert that the diamond is found at Adam's Peak; but this is improbable, as there is no formation resembling thecascalhaoof Brazil or the diamond conglomerate of Golconda. If diamonds were offered for sale in Ceylon, in the time of the Arab navigators, they must have been brought thither from India, (Journ. As. Soc. Beng.xiii. 633.)

During the dynasty of the Kandyan sovereigns, the right of digging for gems was a royalty reserved jealously for the King; and the inhabitants of particular villages were employed in their search under the superintendence of hereditary officers, with the rank of "Mudianse." By the British Government the monopoly was early abolished as a source of revenue, and no license is now required by the jewel-hunters.

Great numbers of persons of the worst-regulated habits are constantly engaged in this exciting and precarious trade; and serious demoralisation is engendered amongst the villagers by the idle and dissolute adventurers who resort to Saffragam. Systematic industry suffers, and the cultivation of the land is frequentlyneglected whilst its owners are absorbed in these speculative and tantalising occupations.

The products of their searches are disposed of to the Moors, who resort to Saffragam from the low country, carrying up cloth and salt, to be exchanged for gems and coffee. At the annual Buddhist festival of the Pera-hara, a jewel-fair is held at Ratnapoora, to which the purchasers resort from all parts of Ceylon. Of late years, however, the condition of the people in Saffragam has so much improved that it has become difficult to obtain the finest jewels, the wealthier natives preferring to retain them as investments: they part with them reluctantly, and only for gold, which they find equally convenient for concealment.[1]

1: So eager is the appetite for hoarding in these hills, that eleven rupees (equal to twenty-two shillings) have frequently been given for a sovereign.

The lapidaries who cut and polish the stones are chiefly Moors, but their tools are so primitive, and their skill so deficient, that a gem generally loses in value by having passed through their hands. The inferior kinds, such as cinnamon-stones, garnets, and tourmaline, are polished by ordinary artists at Kandy, Matura, and Galle; but the more expert lapidaries, who cut rubies and sapphires, reside chiefly at Caltura and Colombo.

As a general rule, the rarer gems are less costly in Europe than in Colombo. In London and Paris the quantities brought from all parts of the world are sufficient to establish something like a market value; but, in Ceylon, the supply is so uncertain that the price is always regulated at the moment by the rank and wealth of the purchaser. Strange to say, too, there is often an unwillingness even amongst the Moorish dealers to sell the rarest and finest specimens; those who are wealthy being anxious to retain them, and few but stones of secondary value are offered for sale. Besides, the Rajahs and native Princes of India, amongst whom thepassion for jewels is universal, are known to give such extravagant prices that the best are always sent to them from Ceylon.

From the Custom House returns it is impossible to form any calculation as to the value of the precious stones exported from the island. A portion only appears, even of those sent to England, the remainder being carried away by private parties. Of the total number found, one-fourth is probably purchased by the natives themselves, more than one-half is sent to the Continent of India, and the remainder represents the export to Europe. Computed in this way, the quantity of precious stones found in the island may be estimated at 10,000l. per annum.

RIVERS.—From the mountainous configuration of the country and the abundance of the rains, the rivers are large and numerous in the south of the island—ten of considerable magnitude flowing into the sea on the west coast, between Point-de-Galle and Manaar, and a still greater number, though inferior in volume, on the east. In the low country, where the heat is intense and evaporation proportionate, they derive little of their supply from springs; and the passing showers which fall scarcely more than replace the moisture drawn by the sun from the parched and thirsty soil.

Hence in the plains there are comparatively few rivulets or running streams; the rivers there flow in almost solitary lines to the sea; and the beds of their minor affluents serve only to conduct to them the torrents which descend at the change of each monsoon, their channels at other times being exhausted and dry. But in their course through the hills, and the broken ground at their base, they are supplied by numerous feeders, which convey to them the frequent showers that fall in high altitudes. Hence their tracks are through some of the noblest scenery in the world; rushing through ravines and glens, and falling over precipitous rocks in the depths of wooded valleys,they exhibit a succession of rapids, cataracts, and torrents, unsurpassed in magnificence and beauty. On reaching the plains, the boldness of their march and the graceful outline of their sweep are indicative of the little obstruction opposed by the sandy and porous soil through which they flow. Throughout their entire course dense forests shade their banks, and, as they approach the sea, tamarisks and over-arching mangroves mark where their waters mingle with the tide.

Of all the Ceylon rivers, the most important by far is the Mahawelli-ganga—the Ganges of Ptolemy—which, rising in the south near Adam's Peak, traverses more than one-third of the mountain zone[1], drains upwards of four thousand square miles, and flows into the sea by a number of branches, near the noble harbour of Trincomalie. The following table gives a comparative view of the magnitude of the rivers that rise in the hills, and of the extent of the low country traversed by each of them:—
