TELLS OF THE GREAT MINE AND OF A ROYAL DIVE UNDER THE SEA.

Botallack, to the dark depths of which we are now about to descend, is

the most celebrated mine in the great mining county of Cornwall. It

stands on the sea coast, a little more than a mile to the north of St.

Just. The region around it is somewhat bleak and almost destitute of

trees. In approaching it, the eyes of the traveller are presented with

a view of engine-houses, and piles of stones and rubbish, in the midst

of which stand a number of uncouth yet picturesque objects, composed of

boards and timber, wheels, ropes, pulleys, chains, and suchlike gear.

These last are the winding erections of the shafts which lead to the

various mines, for the whole region is undermined, and Botallack is only

one of several in St. Just parish. Wherever the eye turns, there, in

the midst of green fields, where rocks and rocky fences abound, may be

seen, rising prominently, the labouring arms, or "bobs," of the pump and

skip engines, and the other machinery required in mining operations;

while the ear is assailed by the perpetual clatter of the "stamps," or

ore-crushing machines, which never cease their din, day or night, except

on Sundays.

Botallack, like all the other mines, has several "shafts" or entrances

to the works below, such as Boscawen Shaft, Wheal Button, Wheal Hazard,

Chicornish Shaft, Davis Shaft, Wheal Cock, etcetera, the most

interesting of which are situated among the steep rugged cliffs that

front and bid defiance to the utmost fury of the Atlantic Ocean.

From whatever point viewed, the aspect of Botallack mine is grand in the

extreme. On the rocky point that stretches out into the sea, engines

with all their fantastic machinery and buildings have been erected. On

the very summit of the cliff is seen a complication of timbers, wheels,

and chains sharply defined against the sky, with apparently scarce any

hold of the cliff, while down below, on rocky ledges and in black

chasms, are other engines and beams and rods and wheels and chains,

fastened and perched in fantastic forms in dangerous-looking places.

Here, amid the most savage gorges of the sea and riven rocks--half

clinging to the land, half suspended over the water--is perched the

machinery of, and entrance to, the most singular shaft of the mine,

named the "Boscawen Diagonal Shaft." This shaft descends under the sea

at a steep incline. It is traversed, on rails, by an iron carriage

called the "gig," which is lowered and drawn up by steam power.

Starting as it does from an elevated position in the rocks that are

close to the edge of the sea, and slanting down through the cape,

_outward_ or seaward, this vehicle descends only a few fathoms when it

is _under the ocean's bed_, and then its further course is far out and

deep down--about two-thirds of a mile out, and full 245 fathoms down!

The gig conveys the men to and from their work--the ore being drawn up

by another iron carriage. There is (or rather there was, before the

self-acting brake was added) danger attending the descent of this shaft,

for the rope, although good and strong, is not immaculate, as was proved

terribly in the year 1864--when it broke, and the gig flew down to the

bottom like lightning, dashing itself to pieces, and instantly killing

the nine unfortunate men who were descending at the time.

Nevertheless, the Prince and Princess of Wales did not shrink from

descending this deep burrow under the sea in the year 1865.

It was a great day for St. Just and Botallack that 24th of July on which

the royal visit was paid. Great were the expectation and preparation on

all hands to give a hearty welcome to the royal pair. The ladies

arrayed themselves in their best to do fitting honour to the Princess;

the balmaidens donned their holiday-attire, and Johnny Fortnight [see

note 1] took care, by supplying the poor mine-girls with the latest

fashions, that their appearance should be, if we may be allowed the

word, _splendiferous_! The volunteers, too, turned out in force, and no

one, looking at their trim, soldierly aspect, could have believed them

to be the same miners who were wont to emerge each evening through a

hole in the earth, red as lobsters, wet, ragged, and befouled--in a

word, surrounded by a halo of dishevelment, indicative of their rugged

toils in the regions below.

Everywhere the people turned out to line the roads, and worthily receive

the expected visitors, and great was the cheering when they arrived,

accompanied by the Duke and Duchess of Sutherland, the Earl of Mount

Edgecumbe, Lady de Grey, Lord and Lady Vivian, General Knollys, and

others, but louder still was the cheer when the Princess rode down the

steep descent to the cliffs in a donkey-carriage.

The Botallack cliffs themselves, however, were the central point, not

only of the interest, but of the grandeur of the scene, for here were

presented such a view and combination as are not often witnessed--nature

in one of her wildest aspects, combined with innumerable multitudes of

human beings swayed by one feeling of enthusiastic loyalty. Above, on

every attainable point, projection, and eminence, men and women

clustered like gay flies on the giant cliffs, leaving immense gaps here

and there, where no foot might venture save that of a bird. Midway, on

the face of the precipice, clung the great beams and supports of the

Boscawen Diagonal Shaft, with the little gig perched on them and the

royal party seated therein, facing the entrance to the black abyss--the

Princess arrayed in a white flannel cloak trimmed with blue, and a straw

hat with a blue ribbon round it, and the Prince clad in miner's costume.

Underneath, a dizzy depth to gaze down, lay the rugged boulders of the

shore, with the spray of the Atlantic springing over them.

Deafening was the cheer when the gig at last entered the shaft and

disappeared, and intense the anxiety of the vast multitude as they

watched the descent--in imagination, of course, for nothing could be

seen but the tight wire-rope uncoiling its endless length, and

disappearing like a thin snake down the jaws of some awful sea-monster

that had climbed so far up the cliffs to meet and devour it! Now they

are at the shore; now passing under the sea; fairly under it by this

time; a few minutes more and they have reached the spot where yonder

seagull is now wheeling above the waves, wondering what new species of

bird has taken possession of its native cliffs. Five minutes are

passed--yet still descending rapidly! They must be half a mile out from

the land now--half of a mile out on the first part of a submarine tunnel

to America! "Old England is on the lee," but they are very much the

reverse of afloat; solid rock is above, on either side and below--so

close to them that the elbows must not be allowed to protrude over the

edge of their car, nor the head be held too high. Here even royalty

must stoop--not that we would be understood to imply that royalty cannot

stoop elsewhere. Those who dwell in Highland cottages could contradict

us if we did! Presently the rope "slows"--the lower depths are reached,

and now for some time there is patient waiting, for it is understood

that they are examining the "levels," where the stout men of Cornwall

tear out the solid rock in quest of copper and tin.

After a time the thin snake begins to ascend; they are coming up now,

but not so fast as they went down. It is about ten minutes before the

gig emerges from that black hole and bears the Prince and Princess once

more into the light of day.

Yes, it was a great day for Botallack, and it will dwell long in the

memories of those who witnessed it--especially of that fortunate captain

of the mine who had the honour of conducting the Princess on the

occasion, and of whose enthusiasm in recalling the event, and in

commenting on her intelligence and condescension, we can speak from

personal observation.

But, reader, you will say, What has all this to do with our story?

Nothing--we admit it frankly--nothing whatever in a direct way;

nevertheless, indirectly, the narrative may possibly arouse in you

greater interest in the mine down which we are about to conduct you--not

by the same route as that taken by the Prince and Princess (for the

Boscawen Shaft did not exist at the period of our tale), but by one much

more difficult and dangerous, as you shall see.

Before we go, however, permit us to add to the offence of digression, by

wandering still further out of our direct road. There are a few facts

regarding Botallack and mining operations, without a knowledge of which

you will be apt at times to misunderstand your position.

Let us suppose that a mine has been already opened; that a "lode"--that

is, a vein of quartz with metal in it--has been discovered cropping out

of the earth, and that it has been dug down upon from above, and dug in

upon from the sea-cliffs. A shaft has been sunk--in other words, a hole

excavated--let us say, two or three hundred yards inland, to a depth of

some forty or fifty fathoms,--near the sea-level. This shaft is perhaps

nine feet by six wide. The lode, being a layer of quartz, sometimes

slopes one way, sometimes another, and is occasionally perpendicular.

It also varies in its run or direction a little here and there, like a

wildish horse, being sometimes met by other lodes, which, like bad

companions, divert it from the straight course. Unlike bad companions,

however, they increase its value at the point of meeting by thickening

it. Whatever course the lode takes, the miner conscientiously follows

suit. His shaft slopes much, little, or not at all, according to the

"lie of the lode."

It is an ancient truism that water must find its level. Owing to this

law, much water accumulates in the shaft, obliging the miner to erect an

engine-house and provide a powerful pumping-engine with all its gear, at

immense cost, to keep the works dry as he proceeds. He then goes to the

shore, and there, in the face of the perpendicular cliff, a little above

the sea-level, he cuts a horizontal tunnel about six feet high by three

broad, and continues to chisel and blast away the solid rock until he

"drives" his tunnel a quarter of a mile inland, which he will do at a

rate varying from two to six feet per week, according to the hardness of

the rock, until he reaches the shaft and thus provides an easy and

inexpensive passage for the water without pumping. This tunnel or level

he calls the "Adit level." But his pumping-engine is by no means

rendered useless, for it has much to do in hauling ore to the surface,

etcetera. In process of time, the miner works away all the lode down to

the sea-level, and must sink the shaft deeper--perhaps ten or twenty

fathoms--where new levels are driven horizontally "on the lode," and

water accumulates which must be pumped up to the Adit level, whence it

escapes to the sea.

Thus down, down, he goes, sinking his shaft and driving his levels on--

that is, always following the lode _ad infinitum_. Of course he must

stop before reaching the other side of the world! At the present time

Botallack has progressed in that direction to a depth of 245 fathoms.

To those who find a difficulty in realising what depth that really is,

we would observe that it is equal to more than three and a half times

the height of St. Paul's Cathedral in London, nearly four times the

height of St. Rollox chimney in Glasgow, and considerably more than

twice the height, from the plain, of Arthur's Seat, near Edinburgh.

When the levels have been driven a considerable distance from the shaft,

the air naturally becomes bad from want of circulation. To remedy this

evil, holes, or short shafts, called "winzes," are sunk at intervals

from the upper to the lower levels. These winzes are dangerous traps

for the unwary or careless, extending frequently to a depth of ten or

fifteen fathoms, and being bridged across by one or two loose planks.

Ladders are fixed in many of them to facilitate progress through the

mine. When a miner drives the end of his level so far that the air will

not circulate, a new winze is usually sunk down to him from the level

above. The circulation is thus extended, and the levels progress

further and further right and left until they occupy miles of ground.

The levels and shafts of Botallack, if put together, would extend to not

less than forty miles, and the superficial space of ground, on and

beneath which the mine lies, is above 260 acres.

When the lode is rich, and extends upwards or downwards, it is cut away

from between levels, in a regular systematic manner, strong beams being

placed to support temporary platforms, on which the miners may stand and

work as they ascend. When they have cut all the lode away up to the

level above them, a false timber bottom is made to replace the rocky

bottom of the level which is being removed. Thus, in traversing the old

workings of a mine one suddenly comes to great caverns, very narrow, but

of such immense height above and depth below that the rays of your

candle cannot penetrate the darkness. In such places the thick short

beams that were used by the old miners are seen extending from side to

side of the empty space, disappearing in dim perspective. Woe betide

the man who stumbles off his narrow plank, or sets his foot on an

insecure beam in such places! Where such workings are in progress, the

positions of the miners appear singularly wild and insecure. The men

stand in the narrow chasm between the granite walls above each others'

heads, slight temporary platforms alone preserving them from certain

death, and the candles of those highest above you twinkling like stars

in a black sky.

In these underground regions of Botallack, above three hundred men and

boys are employed, some of whom work occasionally by night as well as by

day. On the surface about two hundred men, women, and boys are employed

"dressing" the ore, etcetera.

Other mines there are in the great mining centres of Cornwall--Redruth,

St. Just, St. Austell, and Helston, which are well worthy of note--some

of them a little deeper, and some richer than Botallack. But we profess

not to treat of all the Cornish mines; our object is to describe one as

a type of many, if not all, and as this one runs farthest out beneath

the sea, is deeper than most of the others, and richer than many,

besides having interesting associations, and being of venerable

antiquity, we hold it to be the one most worthy of selection.

With a few briefly stated facts we shall take final leave of statistics.

As we have said, the Boscawen shaft measures 245 fathoms. The

ladder-way by which the men ascend and descend daily extends to 205

fathoms. It takes a man half an hour to reach the bottom, and fully an

hour to climb to the surface. There are three pumping and seven winding

engines at work--the largest being of 70 horse-power. The tin raised is

from 33 to 35 tons a month. The price of tin has varied from 55 pounds

to 90 pounds per ton. In time past, when Botallack was more of a copper

than a tin-mine, a fathom has been known to yield 100 pounds worth of

ore, and a miner has sometimes broken out as much as 300 pounds worth in

one month.

The mine has been worked from time immemorial. It is known to have been

wrought a hundred years before it was taken by the present company, who

have had it between thirty and forty years, and, under the able

direction of the present manager and purser, Mr Stephen Harvey James,

it has paid the shareholders more than 100,000 pounds. The profit in

the year 1844 was 24,000 pounds. At the termination of one period of

working it left a profit of 300,000 pounds. It has experienced many

vicissitudes of fortune. Formerly it was worked for tin, and at one

period (1841) was doing so badly that it was about to be abandoned, when

an unlooked for discovery of copper was made, and a period of great

prosperity again set in, during which many shareholders and miners made

their fortunes out of Botallack.

Thus much, with a humble apology, we present to the reader, and now

resume the thread of our narrative.
