Kayser, E. A. Geological and Mining Report on the Etheridge Gold- 

 field, N. Queensland. Queenslander, vol. x. n. ser. no. 11, p. 24. 



The Etheridge gold-field lies in a large basin at a height of 1200 ft., 

 about 225 miles W. of Cardwell. The basin consists of six rock-forma- 

 tions: — a. Mctamorphic granite traversed by auriferous quartz-reefs ; 

 h. Metamorphic mica-schists, associated with a; c. Hard crystalline 

 diorite with auriferous quartz-reefs ; d. Hard grey granite, producing 

 a hungry, gritty soil ; e. Porphyry, forming rough rocky ridges ; /. Con- 

 glomerate and sandstone. The last three have not been found to be 

 auriferous. The quartz-reefs are rich in minerals, as iron-pyrites, 

 galena, manganese, red and brown oxide of iron, oxide of copper, ochre, 

 and white and yellow lead-ore. R. E., Jun.

To a great extent identical with the paper read before Roy. Soc. 



N. S. Wales in 1873, and published as a pamphlet (8vo, Sidney) in 



the same year. The diamond-drift lies in a basin -shaped valley of 



Devonian or Carboniferous age, and in places is overlain by a basaltic 



flow, near Bingera. The diamonds are found near the surface of the 



drift only; are usually small; the individual crystals not well developed,
