THE COMSTOCK LODE, 45 



Like the west vein, it is faced witli selvages of clay. That on the east, parting 

 it from the country propylite, contains the same rolled pebbles as were men- 

 tioned in the Belcher, which, through the whole lode, distinguish the east clay 

 from the west selvage; the latter is drier, more uniformly pasty, and carries 

 no pebbles. Ore was wholly wanting in the Crown Point workings of this 

 vein down to 30 feet above the 500-foot level, where, 130 feet east of the shaft, 

 and 60 feet south of its plane, a small silver deposit made its appearance, occu- 

 pying 20 feet of the quartz body, narrowing as it descended, and entering it 

 like a wedge. In the Yellow Jacket, 60 feet north of Crown Point shaft, on 

 this same level, lying in similar contact with the east clay, was also a small 

 body of workable ore, 30 feet long and 20 feet high. Above the sixth station 

 this same body was sufficiently rich to be worked. A similar concentration 

 occurred above the 700-foot level, and continued north through the Kentuck 

 claim into the Yellow Jacket. On the 800-foot level the ore occupied three 

 sheets in the quartz, thinning to mere edges upward, but widening downward, 

 decreasing in richness until the ore was disseminated throughout the vein. 

 On the 800-foot level the bonanza began to pitch to the north; on the 900- 

 foot level there remained only 25 feet of ore, which in a few feet of depth ran 

 into the Kentuck, leaving below this, as far as the deepest explorations have 

 gone in the Crown Point, a vein of utterly barren quartz. All the western 

 cuts from the low levels discover a large clay-seam, approaching gradually in 

 depth toward the west selvage of the east vein. It is without doubt the same 

 wall which, higher up, curves over to a horizontal position and terminates the 

 west vein. 



A considerable change takes place in the short distance of 270 feet, 

 between the plane of the section just described and that through the Yellow 

 Jacket south shaft; also on Atlas-Plate 8, The western vein has increased from 

 50 to an average_of 110 feet wide, its west selvage maintaining nearly the same 

 dip as in the Crown Point mine, but recurving slightly to the east. The eastern 

 side of this vein makes a bold swell to the east on the 190-foot level, recurving 

 to the west on the 360-foot level, and again ■widening out upon the terminating 

 wall to nearly 200 feet. The ore, instead of being distributed equally through 

 the whole of this large mass of quartz, is on a central zone or sheet about 

 equaling the whole thickness of the vein in the Crown Point section. The
