onkland (Aurelia), wkicli are down 1,200 and 1,300 feet respectively. Had it con- 
'nued with its regular strike and dip, the ‘ Tliird Bed ’ would have been met with in the 
OTmer shaft at a depth of about 750 feet, and in the latter at about 900 feet. The 
•country passed through in the two shafts is very similar, consisting chiefly of altered 
’’atiSed rocks of a grey or greenish colour. The lines of stratification are well 
^''irked in the finer grained rocks. Some of the deepest rocks are very much altered 
chloritic, and resemble the lowest beds on the northern side of the field 
IS difficult to understand how the very groat thickness of the fine laminated grey- 
-VTith shales, which occurs in the Union, the South Ellen Harkins and Wilmot, 
® Ellen Harkins, the Wilmot Extended, &c., &c., would thin out and disappear 
in so short a distance ; and it is far more probable that a fault occurs between 
j ® ^-Wo points; if so, it must run in a direction so as not to disturb the Upper Shales, 
they are continuous throughout the Smithfield, Glanmire, and Monkland Claims, 
only direction that such a fault could run in would be about north-north-east, or 
about 
parallel with that in the Monkland and Abyssinia,

About two and a-half miles further south-east, near the Dawn Shaft, a bluish 
Westone is seen. It can only be traced for a few yards, and the direction of its dip is 
Immediately west of it are the thick masses of shale which occur every- 
j. West of the [auriferous] Gympie beds. It would appear, therefore, that this

from this bed.” 
“In the No. 2 South Ellen Harkins Leasehold the laminated grey wacke with
