have already fallen, owing to excavations chap. 
beneath their foundations. All the metallic veins ^ 
extend north and south; their inclination or dip- 
ping being from tvest to east, at an angle of about 
60°. They run parallel to each other. The 
principal veins are six m number ; but there are 
many smaller ramifications from these, which 
often prove very rich. The six principal veins 
are as follow ; beginning from the luest, and pro- 
ceeding eastivard. 
' I. The first is called Theresa-schadt. In this Thereia- 
schadt. 
vein the matrix of the ore is principally clay, and 
red ferruginous jasper, or sinople, so penetrated 
by clay, and by the oxide of iron, that it is often 
friable. The ore itself is for the most part lead, 
the matrix being everywhere traversed by small 
veins and crystals of quartz. The average 
width of this vein is two fathoms : its depth 
unknown. 
II. The second is called the Hospital vein, and Ho,pitcd 
. . Vein. 
corresponds with that of Theresa; but it is 
much broader, being about twenty-two fathoms 
wide, although not pure throughout this width. 
It contains many foreign substances belonging 
to the mountain in which it lies. It is distant 
from the Theresa vein 120 fathoms.
