the effects of the Della fault, and D the structure resulting from the Clark 
fault, which is that existing at the present day. In determining the relative 
ages of these different fault systems the fact of the late ones cutting and 
faulting the earlier ones, as shown in the figures, is important. Valuable 
information is also obtained from the ore deposition, for the period of miner- 
alization seems to have been restricted as compared with that of faulting. 
Thus the Silver fault was mainly premineral; the Della and the Alta faults 
began to form previous to the ore deposition, but continued after it, and the

Clark fault is almost entirely postmineral, only secondary deposits of ore 
having formed along it. 
LENADO. 
Northward from the Alta Argent mine in Smuggler Mountain no 
ore has been found for several miles. Following along the metalliferous 
zone, the first productive locality is in Lenado Canyon, where the 
mining village of Lenado is situated. Pl. X XVII gives a general view of 
this village, now in a rather dilapidated condition. This view is taken,
