and otlierwise useless diamonds, such as constitute the by far 

 greater product of all diggings. 



Afeicaf Diamond Fields. 



Turning now to South Africa, we find that the diamond field 

 has become wonderfully prolific since 1870. The facts ascertained 

 up to November, 1871, have been collected by Professor Rupert 

 Jones, F.G-.S., of the Royal Military and Stafi" Colleges, at 

 Sandhurst, in a reprint of his own paper iu the Geological Mag- 

 azine for February, 1871, supplemented by fresh details of other 

 writers, and printed for private circulation only. These details 

 consist of " Letters hy Mr. Cooper, Government Surveyor, written on 

 the Diamond Fields, Vaal River" with foot-notes by Prof. 

 Jones, — of a paper read before the Society of Arts, " On South 

 African Diamonds, ly Professor Tennant, of King^s College, 

 London," — of some observations by the latter before the Royal 

 Geographical Society " On the Discovery of Diamonds in the Cape 

 Colony" — and of an abstract from the Times of the shipments of 

 diamonds during 1869 and 1870, together with a note from the 

 Proceedings of the Q-eological Society on the large size of 

 diamonds from the Cape, many out of 10,000 examples being 

 from 30 to 90 carats each. 



Since that, he has communicated to the G-eological Society, 

 with additional notes by himself, a paper " On the Diamond Gravels 

 of the Vaal River, South Africa, hy George W. Stoio, LJsq.," and 

 also " Notes on the Fossils of the Devonian Rocks of Witzenberg, 

 Gape Colony." 



Dr. Hooker also communicated a paper, in 1871, to the same 

 Society, by Dr. John Shaw, " On the Geology of the Diamond Fields 

 of South Africa." [See Q. J., Feb., 1872.] 



In 1871 also, a pamphlet, with sections, was published at Cape 

 Town, entitled " Notes on the Diamond Fields, hy F. J. Dunn," 

 formerly on the Geological Survey of Victoria. 



A little book called the " Digger's Practical Guide" went into 

 a second edition at Cape Town, in 1870.
