As regards the internal circumstances on which the progress of the

mining industry depends, these are the employment of the most improved

methods and means of production. They comprise the most perfected

machinery and appliances, and the latest processes of metallurgical and

chemical science. Speaking generally, it may be said that on the Rand at

the present time are employed the most up-to-date skill and technical

knowledge, and the latest devised mechanical appliances. This, by the

way, is only true of individual mines however. The equipment of the mass

varies greatly, and necessarily so, since the conditions of one mine

differ vastly from those of its neighbour; and distant and even

contiguous localities require unlike treatment, according to the nature

of the ore or reef worked and other local conditions. The improvement

effected hitherto is evidence, however, of the initiation and energy

which have been displayed by the heads of the mining industry in the

past, and an earnest for the future, while the progress achieved abides

as an invaluable guide for all future mining operations in like

geological formations.

The knowledge of how best to treat the peculiarities of the banket reef

has, however, only been slowly gained, and at the cost of much money and

many unavoidable blunders. For instance, the only metallurgical

operation for the extraction of gold employed up to 1889 was the

stamping mill, and fine gold and amalgam were necessarily abundant in

the tailings which were cast away on the spoil heap. The cyanide

process, and that of the treatment of slimes, were only applied in 1891

and 1898 respectively. Their use has added millions to the yearly output

of gold. The amalgamation process, the chlorination treatment of

concentrates, and the use of frue vanners are other innovations

gradually introduced as results of experiment and experience, and which

have likewise increased the efficacy of the extractive operations.

Similar progress has been shown in the improvement effected in the

mechanical equipment. At first the mining operations were confined to

the primitive digging of a huge trench over the site of the outcrop,

with the simplest delver's tools furnished by the locality. This method

has advanced to the stage of sinking shafts to the enormous depth of a

mile into the bowels of the earth, equipped with the most elaborate

hoisting plant, with underground equipment lit and worked by

electricity, and the complementary surface establishments, at a cost

running into hundreds of thousands of pounds. There yet lies before the

industry the general adoption, not only of these but of other

improvements which experience has shown to be desirable, such as the

practice of sorting of ore, the use of heavier batteries on the score of

greater economy, &c., and their utilisation is merely a question of

time. As, therefore, all these improvements and betterments have been

successively made, and the mining industry is only now gradually--it is

not yet, so far as a large number of them are concerned--entering into

the full use of them, it is obvious that future mining operations must

not only enjoy the same favouring circumstances as those which enabled

the huge mining output of the past, but a very much better environment,

through the more general use of all those methods which experience and

science have shown to be advisable. As a consequence, and in the measure

of the value of these improvements, will the effective output be

ameliorated from now onwards.

The value of the improved circumstances of the mining industry alluded

to is convertible into figures in the terms of working costs and

divisible dividends. The former may be said to be the barometer of the

latter. In the past, in the early days of the mining industry, when the

problems of mine equipment and gold extraction and winning were only

imperfectly understood, the wasteful expenditure of money on inefficient

methods and appliances swallowed up in many cases every vestige of

profit.

It was incidental to the first operations on the then unknown geological

formation of the Rand, when the very science of the goldfields had to be

created. Costs of working on the Rand are now, through the excellent

system devised by the Chamber of Mines, tabulated so that the outlay of

individual mines, or of the mining industry in the aggregate, may be

seen at any moment at a glance. For instance, taking the record for the

eight years from 1890 to 1898 inclusive, for example, the working costs

ranged from 80.8 per cent. of the total value of the gold produced by

eighty-five companies in 1890 down to 68.1 per cent. in 1898, the last

full year before the war, the decrease showing the extent of the

progress made in reducing the working costs. Simultaneously the

dividends increased from 19.2 to 31.9 per cent., testifying to the close

kinship with the costs factor. These figures are a general average taken

over the aggregate of the mines working, and do not represent the ratios

of working costs of individual mines, which differ of course according

to the greater richness of the ore, the fewer difficulties to be

dealt with in winning it, and the methods employed to secure the end in

view. This is exemplified by the fact that in a few of the best equipped

mines costs have been brought down to as low as 17s. 6d. per ton, while

on others they rise to 79s. 6d. and above. The Robinson mine is a case

where, despite adverse circumstances, the enlightened employment of the

latest appliances of science and mechanics has resulted in reducing

costs to an extremely low level. In 1888 the working costs of the mine

were 72s. 1d. per ton; in 1892 they were reduced to 46s. 5d., and in

1896 to 30s. 11d. They have subsequently been reduced to a still lower

figure, and this despite the fact that the ore changed from an oxidised

character to a pyritic, involving greater difficulty and cost to treat.

This mine was the first to introduce frue vanners, the cyanide process

and the treatment of slimes, expending as much as £80,000 in the last

innovation. By means of these it raised its gold extraction from 65 to

90 per cent., and gave encouragement and impetus to all mining on these

fields. The latest costs published for the month of September this year

of thirty-six mines in working give an average of 26s. 3d. per ton,

which shows that operating charges are now at about the same ratio as

they were before the war. Although so reduced, however, they are still

relatively higher than they may be expected to be when the mines settle

back into their normal grooves. The reason for this is that only a few

mines are now working up to their full battery power, and, while costs

are on the full scale, results are less, surface dumps are being drawn

upon for mill service instead of the mine itself, owing to lack of full

supply of labour, &c. When, however, the effects of the important fiscal

reductions just made have had time to exercise their effect in reducing

the cost of imported mining stores, foodstuffs, and the smaller

machinery and metal goods charged by the mines to the working account,

further reductions in the working costs will be possible. Of the actual

money value of this per ton of ore milled, various opinions have been

ventured. It has been estimated by experts that it is possible under

favouring circumstances to reduce the expense of working by some 10s.

per ton, at which rate ore yielding over 5.6 dwt. per ton bullion could

be made to yield a profit. The importance of this not only in improving

the present position of all mining undertakings, but in stimulating the

low-grade mines to come into the working stage, can hardly be

overestimated. With the various difficulties besetting the mining

industry removed, the future working cost level should be lower than at

any preceding period, taking into account the benefit of the recent

fiscal reductions and other governmental assistance in prospect.

Allusion has been made to the probable continuation of the Rand

formation beyond its present area; but, as a matter of fact, the

Witwatersrand series of reefs, or an amplification of them, has been

more or less proved for a distance of nearly one hundred miles to the

north and south. The strike of the reefs is not uniformly continuous--in

fact, the reefs are intersected by quite a numerous series of faults,

and in many places they have been subjected to extensive denudation, to

the extent of complete obliteration of the outcrop in places.

Nevertheless at various points very remunerative mines have been

established, and although, on the whole, the character of possessing a

low-grade ore is attributed to these reefs, this is probably due more to

the very incomplete prospecting to which the area has been subjected

than to any actual lack contrasted with the better known central section

of the Rand. On this subject Mr. Bleloch makes the apposite observation

that "it is not reasonable to think that only the richest portions of

the Witwatersrand zones have been laid open on the surface, and that the

sections which remain covered are poor. It is probable that many

portions of these hidden areas contain reefs, if not rich at least

payable, and this may especially be hoped for in that region where the

reefs are completely hidden, and at the two ends of which, where they

are exposed, they are found to be payable."

The eastern section of this greater Rand is about 30 miles in extent, or

140 miles if the contours of the outcrops be followed. In the western

section the conglomerate may be followed for 90 miles as far as

Klerksdorp, when the formation swerves back to the Vaal River. So far

back as 1890 gold-bearing reefs on the banks of the Vaal River were

known, and identified by experts as the south-western rim of the

Witwatersrand basin; but lack of railway facilities and cheap coal then

precluded their profitable working. This district is now surrounded by

railways, and the circumstances are so improved that the possibility of

creating a new Rand in the locality is regarded as feasible by both

experts and capitalists, as, albeit only low-grade ore has as yet been

met with, this is properly held to be hardly a fair index of what lies

below, for experience in the Central Rand has shown that the reefs often

improve lower down. The recently reported "new discoveries" of reefs

actually refer to this particular district.

The prospect before these outlying areas of the Rand is further

authoritatively confirmed by a recent report of the Commissioner of

Mines, in which he observes: "While the expansion of the Witwatersrand

is certain, the future of mining in the outlying districts will largely

depend upon the introduction of a mining law which will give greater

facilities and hold out greater rewards to the individual prospector and

small capitalist." This observation is true regarding many other mining

fields in the Transvaal besides that of the Greater Rand.

Although in speaking of gold-mining in the Transvaal the Witwatersrand

is usually meant, it must not be lost sight of that the Transvaal

possesses other gold-fields of great potentialities and of older date.

The De Kaap fields in the Barberton district were the object of

attention before those of the Witwatersrand were discovered, and at one

time bulked hugely in the public eye. Unknown reserves, both of alluvial

and quartz gold, exist, those reefs of the latter which have been worked

yielding in many cases a much higher ratio of gold to the ton than do

the famed banket beds of the Witwatersrand. The Sheba mine in this

district, a case in point, is one of the most remarkable gold mines in

the world, nearly 90 feet of ore having been taken out of some stopes.

The quartz reefs extend over a distance of 30 miles, mainly in the hilly

districts, while the alluvium occurs in most of the river valleys. The

development of the district in the past has been hampered by a number of

remediable causes, chief among which are unscientific working,

monopolist concessions, excessive railway and customs burdens, and

general governmental neglect. With the removal of these, gold-mining

here is believed by experts to offer prospects not inferior, perhaps, to

those of the Rand. The recent Government proclamation throwing open the

district to pegging, with the contemplated modifications in the Gold

Law favouring prospectors, are earnests that this splendid mineral

reserve will at last have that justice done to it which is its due. Next

in importance to the De Kaap gold-fields come those of the Lydenburg

district. The gold exists here in a similar quartz reef formation, with,

also, unusually rich alluvial tracts; but not one-tenth of its resources

are known, although since the start of the workings an output valued at

£2,000,000 sterling has been achieved. A number of paying companies are

at work, but the drawbacks under which the development of these fields

labour are very much those which prevail on the Barberton fields. The

northern gold-beds, including the Zoutpansberg, Klein Letaba, Murchison,

Selati, &c., are likewise of the quartz formation, and they have been

worked to a limited extent over a longer period than either of the two

preceding fields. The Murchison gold-belt is particularly noticeable

among these fields. The principal or southern reef, 18 inches in

thickness, is said to extend for 18 miles, and to be workable down to

1000 feet, and to contain a gold contents of £25,000,000 sterling. The

northern reef is estimated to be capable of producing £20,000,000 of

gold. Development waits, in all these auriferous regions, primarily on

the provision of railway facilities to get up machinery and mining

requisites; and the extension of the Pietersburg line, which has been

promised, or the completion of the long-projected Selati railway from

where it left off, would be as the breath of life to the mining industry

here. Two other promising mining fields, generally separately grouped

but really a portion of the De Kaap system, are the Komati or Steynsdorp

and the Swazieland gold-fields. The former exists on the Swazieland

border, not far from Barberton, and is rightly regarded as merely an

outlier of the mineral formations of that district. The numerous reefs

have, however, only yielded as yet low-grade and refractory ores. The

Swazieland fields have only been prospected in the north-west of that

territory, but the results have shown that a considerable body of ore

exists. Its gold output in 1898 totalled 8256 oz. Minor fields are those

of Malmani, on the western border near Mafeking, the Pretoria quartz

reefs, and the banket beds of Vryheid (the last now incorporated into

Natal). The prospects of all these fields are very large, and their

requirements are alike. Conditions tending to lessen the cost of

working, and facilities to induce the advent of the prospector and to

justify the investment of capital, will reverse in their cases the

dubious records of the past, while adding immensely to the wealth of the

Transvaal's gold production resources.

The sum of the foregoing observations is that the future of the

Transvaal mining industry presents a vista of incalculable prosperity.

In the restricted area of the Central Rand alone there is a treasure

of at least £2,871,000,000 awaiting appropriation; and, beyond this huge

sum, there are reserves in the Greater Rand which, reckoned on the basis

of mileage alone, would sixfold this amount. Moreover, as the confines

of the Rand reef formation have not yet been determined, should they be

found to stretch into Natal and Zululand on the one hand, or into

Rhodesia on the other, as recent discoveries would seem to indicate, the

productive possibilities of the future are enlarged proportionately.

Apart from its banket reefs the Transvaal likewise possesses huge gold

reserves in its quartz reef fields in the De Kaap, Lydenburg,

Zoutpansberg, and other districts to the south-east, east, and north,

not to speak of the already opened and promising grounds on the extreme

west, which await development when the Rand conglomerate beds are

exhausted, if they do not--as in all probability they will--receive

attention beforehand. The value of these resources is attested by the

best of all evidence--that of actual productive yield in the past. In

the matter of circumstances, means, and paying results from mining, it

has been shown, and it is incontestible, that the industry now stands,

in every particular, upon a much more advantageous basis than it ever

enjoyed. As regards processes and mechanical appliances, the new era

opens with the substantial asset in hand represented by the accumulated

skill and knowledge of past painful and costly experience and

experiment, so that new mines making a start may lay down their

equipments with the greatest practical certainty and economy and

assurance of successful results, even on low-grade properties previously

deemed unremunerative. In respect of external circumstances, the

conditions are already so improved, or in course of improvement, that

working costs have been--and will be more so in the future, when all the

beneficent proposals contemplated by the Government, and the local

advantages resulting from the new order of things have had time to come

into operation--lessened to the extent of yielding substantial

accretions to the dividends of the already paying mines, while

facilitating the development of the deeper mines, and the multitude of

minor low-grade concerns hitherto incapable of profitable working.

Estimates have been adventured in the earlier part of this chapter of

the amount of the saving of working costs to the extent of 10s. per ton,

but this is a pure approximation, and the actual outcome is likely to be

twofold or more. Similarly the yield of gold per year from the Rand

central district of 37 to 40 millions is only a rough estimate, the

production in the future, as in the past, being likely to be much above

the forecasts, taking into view the beneficent circumstances which will

henceforth rule, the full appraisement of which is at present

impossible.

Altogether, therefore, the outlook is one of undimmed brightness, for

the misgivings entertained in some quarters regarding new taxation

burdens to be imposed, calculated to hamper or hinder the progress of

the industry, must be allowed to have no shadow of substance. The

pronouncements of the Government hitherto, and the recommendations of

their Transvaal adviser, are clear on this head. Taxation will naturally

have to be borne, and the tax on profits was accepted in principle by

the mining industry before the war. Its incidence, whatever be the

amount, will only reduce to a fractional extent that portion of the

yield set apart for dividends, which will bear the burden, whatever it

be, with the greater ease in view of the accretion of dividends rendered

possible by the new conditions. There are, indeed, grounds for assuming

that a part of the agitation on foot is lacking in singleness of aim,

and engineered by persons who have some secondary object to gain. The

rank and file of the mining industry, as well as the best sense of the

Anglo-Saxon community, has, however, confidence in the Government that

it will do nothing harmful to the best interests of the new Colonies in

general, and its staple industry in particular, and, moreover, will be

true to the English principle of inviting the taxed to its councils. It

is in this particular light that the visit of the Secretary of State for

the Colonies to South Africa has such special interest at this

juncture.

THE AGRICULTURAL OUTLOOK

BY LOUIS CRESWICKE

Almost the last message of that prophetic statesman Rhodes was

characteristic: "Support Milner through thick and thin," he curtly and

emphatically said. It is therefore Lord Milner's opinion of the future

settlement of the country which should not merely be read, but marked

and learnt and inwardly digested, by all who are anxious for the

development of British interests in the new Colonies, and who shrink

from a recurrence of the horrible scenes of the past, which owed their

origin mainly to long years of vacillation on the part of Governments

that "swallowed up" the Boers at one moment only to disgorge them the

next. Lord Milner, as Mr. Chamberlain has put it, "is the most effective

instrument in our possession." To his subtle yet gigantic brain, to his

detailed yet comprehensive labours, we are indebted for a plan out of

the chaos, a practical plan by which Briton and Boer may be efficiently

planted side by side on the soil for the agricultural and political

well-being of the newly-acquired Colonies.

It must be remembered that the agricultural resources of the conquered

territory have hitherto been inadequately developed. As it was half a

century ago, so it remains to-day--a pastoral country importing its

cereals, its dairy produce, and even its hay from foreign parts. The

motto of the Boer has never been "Forward," nor has industry been his

strong point. The happy farmstead of five thousand acres which served to

keep his ancestor, served also to keep him comfortably till the date of

the war. Progress lay not with him but with the British settlers in the

region of the Rand, or with the crafty Hollanders who pulled the wires

of the misguided autocrat whose ambitious aim was to "stagger humanity."

The sole appreciable advance came from Great Britain. While mining

hummed apace, agriculture crept laboriously; the country, teeming with

promise, remained in parts entirely barren, in others overrun by the

uncombatted yellow tulip or the incango, both weeds deadly to the soil.

The veldt and the karroo, say the pessimists, offer no home for the

Englishman. They moreover aver that only so long as the mines hold out

will the settler remain in South Africa. But there are others, Lord

Kitchener and Lord Milner among them, who see in the country the latent

possibility of modern North America, or, at least, a great agricultural

future which will endure long after the history of the mineral districts

is a closed volume. The science of irrigation in its most modern

development--"the foundation-stone on which can be built the permanent

prosperity of South Africa"--is capable of transforming the profitless

deserts into flowering gardens and fruitful orchards which in very few

years will do more than pay their way. But to properly develop any

scheme requiring eternal vigilance, industry, and foresight, it is

necessary that a goodly sprinkling of the enterprising British

population shall be dispersed all over the land, so that not in the

towns alone will the characteristics of the dominant race be maintained.
