Mining Department. In a “ wash-out ” which exposed 
the underlying rocks, at a point midway between Reedy 
Creek and Smoking Gully, we found, within a tract 
marked on the map as occupied by metamorpliic schist, 
strata hearing a resemblance to lower silurians. There 
were, first, fifteen inches of unaltered sandstone with thin 
veins of quartz; second, twelve inches of knotted argil¬ 
laceous mica schist; third, a rather . , 
greater thickness of sandstone with thin 
veins of white quartz ; and lastly, another 
layer of the same knotted argillaceous 
mica schist. The strike was N. 40° W., 
dip N. 50° E. 80°. 
For some distance further our route 
was through altered lower Silurian rocks, 
metamorphosed schists, and granitoid 
schists, until we reached a point three 
miles south of Bindi station, when we 
suddenly entered on the Devonian lime¬ 
stones. Well grassed rounded hills, with 
smooth slopes, and scanty timber of low 
growth on the lower parts of the rises, 
are characteristic of this formation. This ^ \/- : 
limestone is fossiliferous. 
A section through Bindi shows the 
rocks in this position :— 
For the purpose of examining the so- 
called upper palaeozoic rocks, one of us, 
in company with Mr. Alfred Ilowitt, left 
the party and followed the course of the 
Tambo for some distance. 
Ascending the river, we found, first, 
a granitic rock, in places somewhat
