cMicountered in gold washing. The section exhibited by a 
‘ claim ’ is somewhat as follows : — 
Vegetable soil 9 inches. 
Ferrugineous Concretions. 
Strata of Granitose Sand of variable character. 
Thin Strata of Cla)', Mica, Sand, &c. 
Washing Stuff. 
Ttotten Granite Bottom. 
1 he ‘washing stuff’ forms the lowest stratum, varying in 
thickness from almost nothing up to two or three feet, but 
averaging two or three inches. It consists of: — 
1 . Coarse granitose sand. 
2. Small quantities of clay. 
3. Fine particles of yellow mica. 
4. Gravel composed of felspar pebbles, chiefly red, some- 
times green or other colours; and quarts either massive or 
crystalline, often in very large crystals. 
5. Black iron (magnetic-titanite of iron), sand, and a few 
scarce pieces of hgematite and specular iron ore. 
6. Topaz sand. 
7. Gold dust. 
I found some reefs of quartz in the neighbourhood of the 
diggings, some of which had been tested for gold, but 
unsuccessfully. They run W.N.W. and E.S.E., whereas 
true auriferous reefs are said to be uniformly North and 
South in direction. In these reefs the quartz is supported 
between walls of felspar rock much decomposed. It a])pears 
to me that such reefs as these originate in the separation of 
the constituents of granite, but I have not hoard of the same 
elsewhere. Now, the fact of gold being associated in tlie
