THE BLACK DANGER. QI

The Orange River Colony and the Transvaal would probably more 

 than adjust the difference, if accurate figures were available ; but 

 there is obviously no cause for alarm. Still I am compelled again 

 to point out that it is the high Coloured death rate that really 

 keeps the balance ; true, the Cape white birth rate is very good, and, 

 with an increasing white population, will increase the Cape's pro- 

 portion of white to black daily, but I must mention that of Coloured 

 children born in the 34 largest towns of the Cape Colony — and they 

 constitute 25% of the whole — over 50% die before they are 5 years 

 old, the fact that the Natal Coloured excess of births over deaths 

 is nearly double the Cape's I am afraid clearly points out that Town 

 life does not suit the native, to put it very mildly. 



The white population of South Africa {i.e.; the four colonies) 

 to-day is probably 1,250,000 and the Coloured population 4.300,000. 

 In igo6 I, foolishly, perhaps, ventured to prophesy that in the year 

 2006 the white and Coloured populations would be equal : time only 

 will prove the result, but, with a Union of our States, restored 

 confidence in the great future of this fair land of ours, the great 

 flood of immigration it must bring, the healthy lives of our people 

 with their high birth rate and low death rate, and, alas, I must say 

 alas, the growing tendency of the natives from many causes quite 

 outside the scope of this paper, to flock to the towns and there lower 

 their vitality, I am inclined to repeat my prophecy, at any rate I 

 am quite convinced there is no " Black Danger." 



CHROMITE ORE FROM THE TRANSVAAL.— 



Samples of this ore, from Jachtlust, were forwarded to the Imperial 

 Institute by the Government of the Transvaal towards the close 

 of igo8. The material consisted chiefly of chromite. with some 

 impurity in the form of pyroxene and felspar. Portions of the 

 samples which contained only a small amount of impurity, partly 

 pyroxene and partly felspar, had a specific gravity of about 4*35. 

 A lump containing a considerable amount of impurity, nearly all 

 pyroxene, had a specific gravity of about 4'io. The two qualities 

 of ore were separately analysed, and gave the following results 

 (Imperial Institute Bulletin, Vol. VII., No. 3, 1909) : — 



ist quality- -nd t|iiality. 



Per cent. Per cent. 



Chromium sesquioxide Cr.Oj 47'<' 3'^'4 



Ferrous oxide FeO -3'99 -i'5 



The first quality ore was pronounced a marketable product 

 having an English value of about £3 5s.' per ton, c.i.f. (March, 

 1909). The second quality ore, though saleable, would have a 

 value of only about £2 los. per ton, c.i.f., that is, the current rate 

 for an ore containing 40 per cent, of chromium sesquioxide.
