Deposits, Limestone Creek.

than that recorded, but from the altitude and latitude of the 
place it is not improbable that this approximate determina- 
tion may be found to be correct within reasonable limits, 
the latitude of the caves being about 87° 7', and the altitude 
3000 feet above sea-level. 
Cavk No. 3. — Dry Cave. 
This is situated close to No. 2, in the same bluff, and is 
probably connected with it by narrow orifices. The interior 
caverns are more lofty, and the stalagmital floors quite dry, the 
scenery being similar to No. 2 Cave, and the general direction 
parallel to the strike of the beds it perforates. The entrance 
is very flat, and at a higher level than No. 2. 
Stony Creek Caves. 
These are, so far as I could examine them, unimportant ; 
flat, low-roofed orifices, through which the flood- waters of 
Stony Creek find their way, and are of limited extent, being 
apparently younger than the Limestone Creek caves. And 
in regard to the latter, it is probable that they are not 
greater than Pliocene age, and have been hollowed since the 
partial denudation of the once superincumbent porphyries, 
for, as previously stated, the mud conglomerates within the 
caves are made up of rounded waterworn fragments of the 
rocks found in situ. I was unable to find anywhere in the 
whole series of calcareous deposits evidences of cavities 
which might have existed and have been filled up by mineral 
constituents during any consolidation of the mass prior 
to the deposition of the porphyries. There are certainly 
numerous small veins of calc spar, but no break in the general 
continuity of the beds. The greater hollowing out of the 
caves on the Limestone Creek are, I think, to be accounted 
for by the more lengthened periods of exposure to subaerial 
influences and the percolation of acid-laden waters; the 
Stony Creek calcareous deposit having been more recently 
laid bare by denudation of the porphyries. So far as a 
superficial examination would enable me to judge, I think 
the marbles at this place will prove of considerable com- 
mercial value, the texture and colour being excellent, and 
the beds more homogeneous than at the Limestone Creek. 
However, this is a matter for determination by commercial 
enterprise, and outside the objects of this paper.
