have completed the number of yards required, or until the pro- 

 gress of the work indicates a proper situation for forming a new 

 line of levels and channels of communication to those mines 

 which are not yet drained. In proportion to the successive 

 acquisition to these subterranean works which are daily ad- 

 vancing, will be the increased operations of the mines, and 

 consequently the increased prosperity of the mining interest, 

 which had most astonishingly 'fallen from the degree it had 

 attained in former years. 



" In a short time, similar effects will be seen in the three 

 remaining mineral ridges of Yauricocha, Caya, and Yanacancha, 

 productive of ores of a better quality than that of Santa Eosa, 

 which has nevertheless obtained the preference for the erection 

 of the first engine upon it from its being more abundant in its 

 peculiar produce, and on account of the greater number of 

 persons interested in this property ; as also its contributing 

 immediately to relieve the necessitous, by employing the work- 

 men in the vicinity of the mines. In my opinion, no event so 

 beneficial has occurred as the erection of the steam-engine, 

 since the discovery and addition of these dominions to the 

 crown of Castile. From this time, by the help of these 

 machines, immense and incalculable riches will accrue to the 

 nation.

 duced by the grand steam-engine placed over the mine of Santa 

 Rosa, one of those situated in the mountains of Pasco, for the 

 purpose of draining the mine and extracting the ores.
