In the neighbourhood of Paris the cultivation of edible mushrooms is

extensively carried on in the catacombs or caverns, seventy or eighty

feet below the surface, where the temperature is uniform all the year

round. In one of the caves of Mount Rouge there are no less than six or

seven miles of mushroom bedding. Among the wonders of the subterranean

world must be classed the bone caves of Europe and other parts of the

world. In some caves in England, the bones of a prodigious bear have

been found, and many hundreds of those of a hyena, considerably larger

and more formidable than those existing in Africa. Besides the bear and

hyena, upwards of a hundred species of extinct animals have been found

in the ossiferous caves of Great Britain, among them being those of the

elephant and a rhinoceros. Though in Europe bone caves contain the

remains of animals very different from those now existing in the same

regions, yet in the caves of Brazil extinct species of nearly all the

territorial quadrupeds now inhabiting this region occur. The Australian

caverns contain fossil bones of a large extinct kangaroo. In New

Zealand the wingless apteryx is still found in the wilds, and the caves

of that country show us that it was preceded by other wingless birds of

gigantic stature; among them the moa, which, when alive, must have stood

about thirteen or fourteen feet high. A complete leg of the bird has

been discovered six feet in length, and portions of the eggs show that

they had been about 6 or 7 inches diameter.

CHAPTER TEN.

ARRANGEMENTS OF THE MINES.

In Germany mining operations are carried on in the most systematic

manner. Miners are dressed as their ancestors were hundreds of years

ago, and they cling pertinaciously to their ancient usages. In some

workings prayers are offered up, led by the engineer, before the miners

descend to their work, while they stand grouped round him at the opening

of the mine, a custom which might well be adopted in our own country.

The German miner retains also the superstitions of his forefathers, and

still believes in the genii of the mines, named Nickel and Kobald, after

whom he has called two metals, nickel and cobalt, originally discovered

in the mines of Saxony.

The Germans have introduced into their mines a regular military system,

and the engineers, who are denominated captains, wear when in full dress

a uniform of a very military appearance, set off by epaulets and gold

embroidery. Not inferior to them, however, are the Cornish miners,

their captains being those who have risen by their industry and

intelligence from the lowest to the highest grades, although men of less

education than their German brethren.

The Spanish miners are a sober and frugal race, enjoying their

cigarettes even while at work. On leaving the mine they put on their

snuff-coloured cloaks and broad-brimmed sombreros. In the southern part

of the Peninsula they wear grass sandals, cloaks of bright colours, and

handkerchiefs bound round their heads. Leading lives of toil and

hardship, their huts are wretched abodes built of stones and mud, their

beds the ground, an iron or copper kettle hung from the roof above the

fire in the centre of the cabin, a few wicker baskets, and a waterbottle

of porous clay constitute their furniture. Still, the lot of the miner

of the Sierra Morena is far superior to that of the miner of Almaden,

who, poisoned by the noxious vapours of mercury, quickly succumbs, ere

he has gained the prime of manhood.

In South America the mining operations of the inhabitants somewhat

resemble those of their Spanish ancestors, their habits and customs

being imitated by the Indians, who have, however, to perform the harder

part of the work. While Mexico and Peru were under the mother country,

the Mita or law of compulsion existed, the Indians being forced to toil

against their will in the mines, but since the emancipation of the

colonies and the abolition of that nefarious law, they have returned to

their agricultural pursuits, and are only occasionally found of their

own free will labouring in the mines.

Various modes are adopted for descending the mines. In some merely a

single rope or chain with a loop at the end in which the miner places

his foot is used, even when the depth is several hundred feet; in other

mines baskets or tubs in which three or four men can stand are employed.

While one of these is hauled up, another descends, and often fearful

accidents have occurred by the tubs striking against each other, when

their occupants have been thrown out. Occasionally the ropes and chains

have given way, and the hapless miners have been dashed to pieces.

Some few years ago, as the engineer and several men of the mine of Meons

were descending standing in a tub, each with a lamp in one hand, and

holding on to the chain above him with the other, a couple of tubs

loaded with coal unhooked theirs, which fell to the bottom.

Providentially they had not relaxed their grasp of the chain above their

heads, and at once letting go their lamps and desperately seizing it

with both hands, they continued their descent, though huge lumps of coal

were falling out of the tubs above them. Wonderful to relate, they

reached the bottom in safety. On another occasion, while the same

engineer was ascending in a tub, it was upset in consequence of the

engineman raising the rope too suddenly. The engineer hanging on by one

leg, with his head downwards was hoisted a height of forty yards, before

the alarm was given and he was lowered to the bottom.

In the same mine, another engineer, while descending in a tub, had his

clothes caught by a strut which projected from the side of the pit; he

here hung suspended while his companions continued to descend, terrified

for his safety and alarmed for their own, as should he fall, they

expected to be crushed by his weight. In vain they shouted for

assistance, the men at the top of the pit having gone out of hearing.

Not until they reached the bottom could they send any aid to their

companion. He in the meantime had been vainly endeavouring to find some

support so as to relieve the strain on his torn garments, which

threatened every instant to give way. After hanging thus for twenty

minutes, he was at length set free, but no sooner was he received in the

tub than he became insensible. A severe illness of long duration

followed, but he ultimately recovered, though he ever afterwards

preferred going down the ladders to descending in a tub. Anecdotes of

the same description could be given without end. Most accidents of this

character have ended fatally. To avoid them various inventions have

been devised, one of which is known as the mounting machine, or

man-engine. It consists of two parallel rods, furnished at equal

distances with steps, while one is raised to a certain height the other

is lowered to the same distance. While the movement of the crank is on

its turning point, the miner passes from the step on which he is

standing to the opposite step of the other. As they are constantly

moving up and down, his next step is back again to the rod he had before

left, which rising a few feet, he is able to step back to the other,

just as it, having gone down, is once more ascending; and thus he

reaches the top with little fatigue.

Far superior to this mode of ascending or descending are the

safety-cages introduced of late years, which have guides the whole

length of the shaft, and bonnets or roofs to protect the heads of the

men within. They are made with several stages, in which either the tubs

or waggons can be placed, or where the miners can stand or sit. If a

rope breaks, a spring placed above the cage and kept taut by the tension

of the rope, is set free, and acts upon a double clutch made of the best

tempered steel. This catch or wedge falls between the wooden guide and

a part of the cage, and brings the latter immediately to a stand-still.

By this means numberless accidents have been prevented. The man-engines

which have been described are dangerous for novices, for should a person

stop at the wrong time, he may be hurled to the bottom, or crushed at

the return stroke.

One of the most frequent accidents to which miners are exposed arises

from an outbreak of fire-damp. To avoid this, various safety-lamps have

been invented. The most celebrated is that known as Sir Humphrey Davy's

lamp. The flame is enclosed in a fine wire gauze, through which, under

ordinary circumstances, the gas cannot penetrate. There are other lamps

in use constructed on the same principle, but superior in some respects.

Too often, however, the miners open them at some fatal moment, or enter

the mine, against orders, with naked candles. Still, by means of these

lamps, when properly employed, many accidents have been prevented.

Another invention exists by which a person can enter in the midst of

impure air. The apparatus was devised by Monsieur Kouquayrol, a French

engineer. It consists of a reservoir made of sheet iron, into which the

air is forced, and, by an ingeniously contrived pump, is secured like a

knapsack to a man's back, and the air is conveyed by means of a tube to

the mouth of a nose, and thus into the lungs at the ordinary pressure,

while a small external valve allows of the escape of the air after it

has been respired.

A still more simple apparatus has been invented by Monsieur Galibert.

The system for condensing the pure air is more perfect, while the

reservoir consists of a well-prepared goat-skin, which, when inflated, a

man can with ease carry on his back. It is furnished with a similar

contrivance to the former, a tube passing from the reservoir to the

mouth, while the nostrils are compressed, the eyes and head are

protected, so that provided with it, a person may exist for a quarter of

an hour in the foulest atmosphere, or in the midst of dense smoke.

Although the metal miner is subjected to fewer accidents than are his

brethren working in coal mines, the atmosphere in the former is far more

destructive to human life. In lead mines, the duration of life averages

scarcely more than thirty-two years, and in those containing arsenical

pyrites or quicksilver ores, the average is still lower. Before the use

of gunpowder in underground operations, the rocks containing the ore

were attacked with fire, indeed the practice is still retained in some

countries. Huge wood fires are made up against the face of the rock,

which becomes shattered and traversed by cracks, and when cooled, it is

easily detached with a pick or fork. Of late years, however, machines

have been devised for boring or breaking the rock. Some form a hole by

the continuous motion of a rotating drill, others by means of

intermittent blows. One of these rock-boring machines, manufactured by

Messrs. Turner, of Ipswich, performs its work by a combination of both

these operations. By the employment of these machines, the formation of

the tunnel under Mount Cenis was greatly facilitated. An example has

already been given of the way in which people have been saved from the

effects of inundations in mines, others have been dug out when buried by

the fall of roofs, but almost countless are the numbers who have

perished from other causes, for if the first have destroyed their

hundreds, the fire-damp in coal mines has proved the destruction of

thousands. It was at one time considered right every night to provoke

an explosion by lighting the fire-damp in order that the working stalls

should be accessible next morning. The man who performed this dangerous

operation wore a thick covering of wool or leather, his face was

protected, and his head was covered by a hood like a monk's cowl. He

crept along the ground, carrying in his hand a long pole with a light at

the end of it. He was known in the English mines as the fireman, but in

the French he was called either the cannonier, the monk, or the

penitent, the latter name being given him from his dress resembling that

of certain so-called religious orders in the Romish Church. Too

frequently the hapless penitent was destroyed by the explosion he had

provoked.

Our two friends, however, might have written several large volumes had

they given accounts of even a portion of the interesting matters

concerning mines which they gathered up during their long and varied

tour.

Mark did not fail to benefit largely by the information he obtained, and

he ultimately, with the numerous improvements he introduced, became the

proprietor of two of the coal mines in which he had worked in his

boyhood, while his young sister, on whom he had had the satisfaction of

bestowing a high-class education, refined in mind and manners, became

the wife of his friend and fellow-traveller.
