TO PARRAS, 473 
miles through a defile, we emerged into a broad plain, 
bounded on the east by a high range of mountains. 
This plain was about ten miles across; after it we passed 
a second range, and beyond this another plain of six 
or eight miles more, which brought us to La Noria de 
Pedrecevia, a well with a wheel, distant twenty-seven 
miles from our starting place. Here is a church, ap-

coming into possession, had leased the estate. The

of the mines, and devoted themselves to working over 
the scoria and cinders which lay in the hillocks near 
the town, and from which they were able by some 
improved process to extract a considerable amount of 
the precious metal. Seftor Pedrecefia took possession 
himself about six months before our visit, finding the 
place was fast running down. With this revival it has 
quite an air of business. Don Tomas took us into the
