“On the Kennedy Bay side—1lst Section is a coarse granular, or sub- 
crystalline rock, light in colour, and containing pyrites, but weathering freely 
to a dark brown. On the west side of this band of rock are two quartz veins, 
5 and 3 inches respectively, trending north-east, and underlying to the west 
at 20°. 
* The samples of these sent gave at the rate of 28 grains per ton of gold. 
“Ind Section and 3rd Section.— Very compact felstone, or indurated 
claystone full of pyrites in large masses and crystals. 
* A glance at the suite of specimens submitted shows that, while there is 
considerable variety in the rocks cut through in the tunnel, after passing 
the 3rd section of 300 feet from the west end they all belong to the same 
group. The presence of carbonate of lime in large quantities, both as a 
constituent of the hardest and densest parts of the rock, and as secondary 
deposits in veins, is very interesting, and shows that, even if these rocks had at 
first a volcanic origin, as has been supposed, they have since undergone much 
alteration. The marked change at 300 feet, and the presence in the rock at 
section 3 of rolled fragments of the more interior rock, is sufficient proof of 
the existence of two formations belonging to different periods. 
“ All the rocks will be exhaustively analyzed and microscopically examined, 
so that the fullest benefit to science may be obtained from this most interesting 
work.”
