 But engineer Schmeiser's report con
 tains greater, though less definite sur prises.
 1.-The fact," he says, "that that tht
 above tract under consideration has {
 length of only eleven and oue-half mile s
 while the Rand is about fifty miles long
 warrants the conclusion that the tota
 results of mining here must considerably
 exceed the figures as above worked out even If many of the mines lying outside
 of this tract should prove to be less pro
 tltable than those lyIug near Johannes berg.
 But a reduction of the cost of pro- | duction will probably hereafter permit
 the working of even other reefs which
 are not now considered profitable. from this fact further increase Tn produc- ton would result. Already the Robin Sen GC:a Mining Company has decided
 to begin work this year upon the Man
 Reefs, since It has been shown by the
 largest investigations to contain gold in
 paying quantities at lower depths.
 The cognlomerate reefs at Klerkshop,
 about l25 southwest of Johannesberg,
 resemble Tn their character some of the
 members of the NitWatersrand group,
 and are therefore often considered to be western squirt or otfshoots of it. At this place, unfortunately, swindling schemes Tn mining shares began contem- poraneously with the sudden develop ment ef the mining industry at the Rand, and the reaction from this spec ulatlon has not yet been overcome. In my opinion considerable mining in dustry can be developed here when the confidence of the public has been re- gained, when capital turns in this dl- rection, and when soul q business man. agement has been introduced. Mining here, owing to the mere limited extent of the deposits, will, of course, remain far behind that at the Rand. The mea- sure of its development can rot yet be estimated.
 'lhe gold fields at Bryheid, 1SO miles southeast of Johannesburg, which I did not personally investigate, is said to be similar m its geological character to that of the Witwatersrand and Klerks- drop. Reports, however, vary greatly
 
 Ut remains to be mentioned that gold-bearing copglomerate reef was dis covered at Havertsburg, in the Zout- pansberg district; also that similar reefs exist on the Duivei's Kantoor and on the tops of the mountains which inclose the De kaap district to the south and east. Even through these deposits do not contain more than 415 pennyweig hts about S4 worth) of gold to the ton, still they furnish proofs that the appearance of gold in conRlomerates in the Trans vaal is of extraordinarily wide ex- tent.
 In the De Ksap, Little Letaba, Nal msni, Marabastad, Houtboschberg and Selati gold fields the metal occurs pI in- cipally ID quartz veiEs which take the direction and dip of the noun tains, but sometimes running crosswise to the strata of the mountains.
 ''Some of the deposits in the northern part of the Transvaal are to be explain d either as oslitc or as lentIcular veins, that is, as Assures, which diminish with the trend and dip of the strata for the consioera ole distance, GwindliDg finally at mere fuccan and swelling later. to a thickness.

 Up at the present time a eonsidera- ble depth has been reached only in the Sheba mine. near Barbeton, where a perpendicular depth of 3S0 feet below the outcroppIng and l65 feet below Fig tree Creek has been reached. All other mining enterprises in the De Kaap dis trict are still at work above the level of the valley. The Letaba and the Birth | day mines in the little Letaba gold field l have reached depths of l30 acd POO feet. | Nearly ell the other enterprises here and in the remaining gold fields are, however, scarcely more than experiment tai, works, which have as yet reached no depth.
 "The development of all these gold fields is hindered by tie lack of capital by the wretched means of trapspOrta- ton, by the lack of coal and by climate OlbCA Mining on large scale is therefore car ried o1 St present only in the Sheba mine, which is operated under specially favorable coHdi ions. From October l, 1892 to Septem Der 30, 1893, there were removed from this mine 33,26l toBs of ore, producing 31, ,S55 ounces of gold, or lS.6 pennyweights per ton, at cost of production of S7S0 per ten.
 'As soon as tbe Witwatersrand, with | it's still great demands for new capital, | has been sufficiently provided for; when, further, the railroad lines from Lorenzo Marquez to Pretoria, with branch line to Barketon, and the line from Kamati- | Poort to Leysdrop have been complet- | ed; finally, as soon as the establishments | already planned and in process of build l ing for transforming the water power of several rather large streams into cleo tric power, to supply the lack of coal, have gone into successful operation, then vein mining will also undoubtedly show a rnpld development. This form of miniug msy then contribute for an indefinite period, and in no inconsider- able measure to the increase of gold in the Transyaal
