370 PROCEEDINGS OF SECTION C. 
An interesting feature about these rocks is the occurrence on 
many of the harder and denser ones of a coating of what appears to 
be secondary silica which imparts a distinct glaze to them. 
Again, much of the material in the banks of the Leatherbarrel 
Creek, lower down Kosciusko Valley, consists of angular and sub- 
angular fragments of altered rocks, with large slabs of the same 
intermixed, and appears to have been conveyed thither by other 
than ordinary fluviatile agency. On the other hand, there is an 
entire absence of any deposits which might be regarded as lateral 
moraines ; neither did we see any satisfactory evidence of any 
roches moutonnées, perched blocks, boulder clay, or morainic 
débris. 
The probable auriferous character of the region may be briefly 
alluded to. As it possesses features so closely resembling those of 
proved auriferous districts where both plutonic and metamorphic 
action have taken place, it is very likely that auriferous reefs will 
eventually be found near and at the contact of intrusive masses 
and dykes with the sediments, and also in both these and the 
plutonic rocks themselves. The district on the western fall from 
Mount Kosciusko, embracing the upper portions of the basins of 
the Gehi River and Snowy, Gehi, and Leatherbarrel Creeks as 
well as the Snowy and Kosciusko Valleys, is-especially worthy of 
attention. 
These observations were made during two visits to the mount, 
but each time adverse weather militated greatly against continuous 
or connected work being done. 
Nore.—Since writing the ‘above, we notice that in a postscript to a paper (Proc. Linn. 
Soc., N.S.W., 1897, Part IV) on the so-called glaciation on Mount Kosciusko, the Rev. J. 
Milne Curran has evidently assumed that the original of this abstract dealt specially with 
that question. He is under a misapprehensien, as only a small portion of it bore on 
glaciation, and the opinions held by us are herein concisely expressed. 
No. 12.—NOTES ON SAMPLES OF ROCKS COLLECTED 
BY Mr. A. E. KITSON anp Mr. W. THORN. 
By A. W. Howirt, F.G.S. 
(Read Tuesday, January 11, 1898.) 
Tun slices have been prepared of a certain number of the rocks 
collected, and the following notes are the result of an examination 
of them under the microscope :— 
I. Metamorphic— 
(1) Phyllite and fine-grained Nodular Schist. 
II, Igneous— 
(2) Granitic-aplite. 
(3) Quartz Hornblende Diorite. 
(4) Andesite.
