Description of the Bare Hills. 355 



Returning again to the point H and tracing off, upon the margin 

 of the brook as before, the distance of one hundred and eighty 

 seven yards from H to J, we discover immediately opposite, or across 

 the brook, and under a shelving projection of rocks near the water's 

 edge, a thick vein of the red Lithomarge, of a pure and beautiful 

 quality. In obtaining specimens from this locality, the same pre- 

 cautions are necessary as in the former instance. 



At the distance of two hundred and thirty yards from the point 

 H, we come to the opening of another deep ravine that stretch- 

 es away to the south. Between the bridge and this point, we ob- 

 serve a remarkable instance of " accessory minerals disseminated" 

 through the entire mass of the rocks ; for, independently of the gran- 

 ular chrome, oxidulous iron, &c. there are numerous crystals or spic- 

 ule, of a substance resembly hornblende intermixed with, and run- 

 ning in all directions through the rocks. 



Of the gisement or geological situation of the rocks of this dis- 

 trict I have hitherto said nothing, by reason of the ambiguity, or dif- 

 ficulties that exist at almost every point. In general, they seem to 

 be promiscuously thrown together in utter confusion. In some pla- 

 ces, something more like order is manifested in their relative position, 

 and at this place they appear to incline to the North West. 



Resuming again our position at the opening of the ravine, and 

 tracing it upon the margin of the small run of water that flows from 

 its head, we find much to interest the mineralogist, in the variously 

 modified substances that are presented to view, as the rocks are, 

 in many places, exposed in situ. As the particular localities upon 

 the sides of this ravine and those to be hereafter mentioned are so 

 readily found, and easy of access, it is considered unnecessary to 

 make any further references, to actual admeasurements or points of

distance. 



Upon the slope of the hill on the east side of the ravine just men- 

 tioned, and but a few rods from the brook at K, extensive operations 

 have been carried on for the purpose of obtaining chrome, of which 

 large quantities, of an excellent quality, were raised. The works, I 

 believe, were carried to the depth of about eighty feet, but have, for 

 some time, been abandoned. In the prosecution of these works, 

 many interesting specimens of minerals were thrown upon the sur- 

 face, such as the red and white lithomarge, green foliated talc, stea- 

 tite, silicate of magnesia, and other magnesian substances. A little 

 farther up the ravine on the west side at L, are extensive excava-
