Section 726, and also from Sections 3035 and 3036. An excel- 

 lent metal is also obtained in various parts from the highly- 

 ferrugiuised conglomerates and compact arenaceous beds of 

 tbe Miocene. 



Conclusion. — Geologically speaking, G-awler and "Western 

 Barossa, thougb moderately provided witb some of the neces- 

 saries calculated to advance people in the general commercial 

 pursuits of life, are not likely ever to attain great mineral 

 prosperity. The soils, formerly of medium fertility, have 

 already yielded their virgin treasures to continuous culture ; 

 and the mineral wealth — never proven to be great — has been 

 steadily decreasing since the auriferous drifts of the South Para 

 and Spike Gully were discovered — the former in 1851 and the 

 latter in 1868. Seeing that both these sources of wealth 

 have passed the zenith of productiveness, especially in an 

 agricultural and horticultural sense, at which the greatest pos- 

 sible return can be obtained for the least possible outlay, it 

 now becomes a serious matter to consider can artificial means 

 be applied to replenish in a day, or a year, the treasure which 

 cost nature thousands — possibly millions — of years to provide.

Paeina. — A private well, about half a mile north-west from 

 the railwav station, had been sunk at the time of my visit, June 

 18, 1882, to a depth of 81 feet. The section is as follows :— 

 Drift overlying Secondary — probably Jurassic — gypsiferous 

 beds, in which salt water Avas struck at 35 feet ; similar gypsum- 

 bearing strata for a further depth of 32 feet ; then a band of 

 fundamental quartzite Avas encountered, from which no water 

 flows, and penetrated to a depth of fourteen feet. The opinion 

 held by local authorities is that an abundant supply of fresh 

 water will be obtained when the quartzite band is pierced; and 

 all that is needed is to puddle back the inflow of salt water 

 derived from the Drift and gypsiferous strata. The creek, in 

 which the so-called "Government Gums" and "well" are 

 situated, has evidently been excavated out of the Secondary 

 limestone, as throughout the neighbourhood the escarpments 

 consist of it. These limestone elevations do not generally 

 exceed 30 feet in height, and are composed — at the surface at
