this mass has been removed, and the surface now exposed presents an unequal distribution of 
it, but in no place an amount worth the expense of raising. It presents, however, the same 
general arrangement as all other veins, that of parallel bands or stripes. In some portions the 
ore is in the proportion of one half, the other half being white flint. Considered as a vein, its 
strike or course is west of north, or N. 10° W., and its dip west. Ten or fifteen feet beneath 
the solid plate of ore, a passage has been made in the solid rock for at least one hundred feet. 
It commences on the northern slope, and runs nearly south. No ore was discovered by 
this procedure, and it could not have been reached, even if there is an abundance of ore, in 
consequence of the dip of the vein. The entrance into the rock being made on the eastern 
side of the vein, and parallel to its course, the adit or drift seemed to be beneath it; whereas 
if the drift had been made east and west, it would have crossed it at a point west of the pre¬ 
sent drift. 
The great difficulty of obtaining ore at this place, is probably in consequence of the great 
derangement produced by several transverse dykes. In the distance of one hundred feet on 
the line of the ore, there are nine dykes, a ground plan of which I have given in the following 
diagram (fig. 82), from which we have a strong probability that they have had more or less 
to do in obscuring the true relations of this mass of ore. The dykes vary in width, but their 
several courses are parallel. Their directions are N. 55° E. 
The relative position of the four veins which I have now described, may be illustrated, as 
a whole, by the following section. They lie nearly in the same east and west range, pursu¬ 
ing in general a course nearly north and south, while the ridges upon which they outcrop 
strike north-northeast and south-southwest.
