Part 7 (1/2)
And then, gloomily seen on high, weird, shadowy creatures, dank and bat-like with their dusky wings, appeared to be hovering just beneath the roof, till a nameless horror seemed to pervade the gloomy atmosphere, and the imagination peopled the place with unearthly creatures which the mind refused to believe were illusory, so real were they in their stony extravagance; yet all were the work of nature, formed through the dark ages slowly, drop by drop.
There they were in the dim nooks and recesses, seeming, as the smoking candles flickered upon their glistening surfaces, to beckon and grin, peering round twisted b.u.t.tresses, gloating, vampire-like, on the pa.s.ser-by from behind the fallen columns, and producing a shuddering horror, as they seemed to be only waiting till the visitors to these awful shades had pa.s.sed before they sprang.
It was here that even the brilliant rays of magnesium failed to dispel the gathered blackness, and the strange shapes stood out more spectral and awe-inspiring than before. And it was water--water everywhere, drip, drip, drip, never ceasing--the hardest of hard water, that the most thirsty in these caverns would shrink from drinking, for he would know that he was sipping liquid stone, the stone that had built up everything around, and which would go on almost silently building fresh wonders until Time should be no more. And in spite of the flash and brilliancy of beauty as opposed to the dull, glistening, slimy look of much of nature's work, there was something shuddering in its inspiration as he who gazed at the same time had what was going on conveyed to him through his ears--the drip of water never ceasing, and its feeble echoes seeming to rustle with mysterious whisper throughout these shadowy cells and proclaim the wonder-work in process of construction.
It was with a strange feeling of relief that they pa.s.sed on out of these awe-inspiring caverns into a region where, in delightful contrast, the eyes were welcomed with a sight of what could only be the dwelling-places of the inhabitants of a kind of fairyland. Here all was graceful pinnacle, delicate spire, tapering point, and slender pillar, each frosted alike with silvery rime, which made the finger shrink when touching them; for it seemed, according to everyday knowledge, quite startling that these beautiful works of nature should feel cool and temperate; the visitor felt that they ought to sting the nerves with pain, for their sparkling effect looked so exactly as though it had been produced by frost.
Icy, too, appeared much of the beauty now--the sparkling fairy couches spread with frosty lace, the gauzy floating folds encrusted with gems.
Everywhere the lights flashed and glittered, refracted in a thousand colours; for here, too, seemed to be the caves of crystal-land, the homes of the water sprites who dwelt where water had now become pure, solid, and perfect for evermore, where water had become pure ice that was not cold, where even the floor was white sparkling sand scattered with gleaming sh.e.l.ls, above which the water fays floated, and the sea sprites played and chased fish in the ice grottoes.
Such were some of George Henty's impressions of the Grotto of Adelsberg, and he concludes by saying that any traveller who has ever had the opportunity of seeing that home of nature's wonders lit up as he had, would surely bear him out in saying that, so far from exaggerating, he has but touched upon a few of the varied and extraordinary beauties of the place.
CHAPTER THIRTEEN.
MINING FOR MERCURY.
Still feeling his great interest in mining to an extent that makes one wonder that he did not make that pursuit the work of his life to the same extent as he made yachting the pleasure, Henty now made his way to Idria to make a careful examination of the quicksilver mines, the property of the Austrian government. The journey was undertaken partly from its being likely to form an interesting letter, but still more probably from a desire to foster his own inclinations. And no wonder!
For it is not every man who could write in perfect sincerity, ”My experience of mines is very extensive,” and then go on to talk like a past master of mining in general, not in support of this a.s.sertion, but in proof of his general knowledge.
Reaching the quicksilver mines, which are, as is probably known, very few and far between upon the face of the earth, he gives a thorough description of the place. The workmen, he tells us, number some six hundred, the buildings connected with the mine are good and well kept, the posts and doors painted the familiar black and yellow of Austria, while the imperial arms, surmounted by the two crossed hammers, are fixed to the various offices.
In old works accounts are given about condemnation to the quicksilver mines and the convict life of the unfortunates, but Henty's account of the place seems to prove everything to be very businesslike and matter-of-fact, and the old descriptions that blackened the administration would appear to have been extremely highly coloured. The government has erected a theatre for the use of the workmen, and has in other ways laid itself out to study their comforts in a manner for which its habitual detractors would hardly have given it credit.
The pay of the miners is about eightpence a day, apparently a very small sum, but which is above the average gain in a country where the necessaries of life are extremely cheap. When they are ill, and this is not infrequently the case, for the fumes of mercury are extremely deleterious, they receive three-quarter pay, together with medicine and medical attendance, while they are provided for in old age.
After this brief socio-political statement, the businesslike miner and student of geology speaks of the formation of the country where the mines are situated. This is an oolite limestone, that is to say, the cream-coloured soft building stone so familiar in building, which hardens in time, and is generally dubbed Bath-stone.
He was rather surprised that a quicksilver mine should be here, and he made a careful examination of the surface of the neighbourhood before descending, but could discover no signs of the existence of a mineral vein, and so felt at a loss to imagine what induced the original investigators to set to work at that particular spot.
Here is his version of the old story which credits the discovery of quicksilver as being due to a barrel-maker who, after making a tub, placed it under a dropping spring to see if it would hold water. When he came to look at it again, he found it contained what he took to be a certain amount of glistening water; but on attempting to move the tub, he discovered it to be so heavy that he could not lift it, the supposed water being the enormously heavy liquid, quicksilver.
Henty also relates that a spring that arose in Idria had been observed to deposit in the hollows of the stone small quant.i.ties of quicksilver.
This came to the notice of a merchant from Trieste, who happened to be stopping in the neighbourhood. Being a business man whose head was screwed on the right way, he came to the conclusion that this quicksilver must issue from the rock in company with water, and that if he sank to a sufficient depth, the source from which the spring drew the mercury would be discovered. Without any delay he obtained a grant from government, began to sink, and carried on quicksilver-mining for some years with success. But it soon became evident to him that the primary source of the fluent metal was much deeper down, and to reach it much larger capital was required than he could command; so, still acting as the business man, he sold his works to the government, no doubt at an excellent profit, and by the government they have been carried on ever since. They are now the richest and most extensive of any in Europe, with the exception only of those at Almaden, in Spain.
Henty's stay in Idria was only short; but being furnished with a guide, and having put on the suit of miner's clothes provided for visitors, he commenced his descent. This was made by means of a number of inclined shafts of admirable masonry, worked in a perfect oval, and about seven feet in height. These can be best conceived by imagining a perfectly dry London sewer being placed nearly on end. In these shafts small stone steps were formed, by which the descent was made without fatigue or difficulty. He considered that these shafts were superior, both in arrangement and workmans.h.i.+p, to anything he had ever seen in his great experience.
On descending he noticed that the mine was worked, to speak technically, in five levels, and that in some places the quicksilver was in the familiar glistening globules in a soft and partially decomposed state.
But the greater portion occurred in the aforesaid limestone itself, and even where it was present in the enormous proportion of eighty per cent it was not visible; but the ore resembled very rich brown haemat.i.te ironstone. In describing his visit, Henty goes on to write about the warmth of the atmosphere and the close mineral odour, and to relate how, in consequence of the deleterious mercurial fumes, the miners are unable to work in the richest parts for more than two hours at a time.
He continues, then, quite as a man accustomed to inspecting mines, declaring that the timbering, i.e. the supports, of the levels, ventilation, and other arrangements of the mine are good. But he never saw labour so completely thrown away in any undertaking of the kind he ever visited; for the miners were constantly employed upon poor barren-looking stuff, which the most unpractised mining man--including, of course, himself--might have seen would never lead to anything. Had their work taken the shape of small galleries for exploration, it might have been explicable; but the men were almost all engaged in greatly widening previously-made pa.s.sages where nothing whatever had been found, nor was likely to be. He accounts for this, like a practical man, by supposing that, as a miner could only work for a few hours a week upon the rich spots, and as the management are obliged to keep a large succession of men for working continuously, they put the men to work in the barren places purely to keep them employed.
Satisfied with his inspection, he at last made the ascent, coming up a nearly perpendicular shaft, worked by water-power, in the large and dirty basket in which the ore is lifted to the surface. He then proceeded to the smelting-houses, where the quicksilver is extracted from the ore. These were about a mile from the town; but the furnaces were not at work at that time of year--October--on account of the fumes thrown off being so extremely deleterious to vegetation and to the cattle which fed upon it, as in grazing they, of course, took up a certain amount of the mercury deposited upon the herbage.
The smelting, or, as it might more properly be called, the distilling, of the mercury is only carried on in winter, when the fumes that escape from the furnaces fall upon the surface of the snow, which in that mountainous country covers the earth, and are washed away when the thaw comes in the spring. The poorer ores are crushed under stamps, and the mineral is separated by dressing and shaking tables. The richer stuff is at once carried to the furnaces, where it is roasted, and the mercurial fumes which are evolved by this process are collected in adjoining chambers. Henty goes on, like a mining expert, to criticise the imperfect way in which the processes are carried out, adjudging that under better management the fumes which spread over the surrounding country would be far less noxious.
The total amount of quicksilver produced by this one mine annually is about two thousand five hundred pounds, and this is exported in iron bottles for the use of the gold and silver mines of Mexico, Peru, and Brazil.
Surprise was expressed at the commencement of this chapter that literature had not lost her able writer for boys by his being absorbed by the mining profession. His remarks concerning miners gained from his own observation pretty well justify this comment, for, moralising upon the people under observation at the quicksilver mines of Idria, he says that among no cla.s.s of the population of various countries is there so great a resemblance as between miners. However the peasantry in general may attire themselves, the miner wears a universal garb. He shaves closely, so that the dust and dirt, which his occupation involves, may be the more readily removed when he returns to the upper air; and if the workers in the lead-mines of the island of Sardinia (where he had been, to study them), the Slav from Illyria, the Frenchman, the Belgian, the Cornish, Welsh and Newcastle miner, with all of whom he had made acquaintance, were ma.s.sed together, the shrewdest observer would be puzzled to separate the men belonging to the different nationalities.
