Mr. Weaver on the 
very rarely, occurred crystallized in octohedrons, and also in the 
elongated garnet dodecahedron, of which I retain specimens. 
3. The ascertained fact that several of the contemporaneous veins 
of quartz, contained in the mountain, were metalliferous, yielding 
magnetic ironstone, iron pyrites, copper pyrites, blende and iron 
ochre, with chlorite, and quartz crystals. 
Under these considerations, the measures proposed by the direc- 
tors were : to continue the stream works, progressively advancing 
toward the head of the several streams ; to examine more closely 
the solid mass of the mountain, by means of trenches to be cut in 
various directions down to the firm rock ; to explore more fully the 
veins already known, and those which might be discovered near the 
surface by the trenches ; and lastly, to try these veins, at a consider- 
able depth from the surface, by means of a gallery or level, to be 
driven into the mountain, in a direction nearly at right angles with 
the general range of the veins, selecting that quarter where they 
appeared to be most numerous. 
These measures, receiving the sanction of Government, they were 
carried into effect: and numerous trials were made by driving and 
sinking on the veins previously known, and subsequently discovered. 
The mineral substances obtained, were subjected to the operations 
both of fire and of amalgamation ; but in no instance was a particle 
of gold elicited from them either by the one or the other process. 
So unsatisfactory a result led to the persuasion, that the gold formed 
no part of the veins which appear in the mountain ; and hence 
Government were induced to abandon the enterprize. 
The same conclusion seems to apply to the tinstone, wolfram, and 
manganese, in discovering which the mining operations equally 
failed. What is then the primary source of these substances, found 
detached in the beds and banks of the streams ? It is not improbable
