and we are proceeding with th<> gmitost activity. The workmen 

 are relieved every two hours, and as they go out they give up 

 their tools to those who succeed them, by which means not a 

 minute is lost. Continuing thus, in the course of a month we 

 shall be at more than 20 yards depth, and have many mines in 

 full activity. The winding engine raises a basket (which is a 

 load) in two minutes ; the draining or steam-engine, with two 

 vibrations per minute, keeps the surface always dry. Both 

 work with the greatest ease, certainty, and regularity. 



"'By dint of searching after a vein of coal, we have at last 

 found one near at hand, of excellent quality and of great rich- 

 ness. The pit we are now at work at is at the distance of a quarter 

 of a league from Kancas, and at the same distance from Yista 

 Alegre which the Cerro is from these works. We have likewise 

 found a vein of plumbago, which was an object of search, on the 

 supposition that it was coal. This substance, of which much 

 is consumed, mixed with grease, to soften the friction of the 

 piston, &c., we have now here ; and thus the necessity of sending 

 to Lima, or perhaps to Europe, for it is obviated.' " 



Within six months of the setting to work the pump-

" We have had the pleasure of receiving a letter from Pasco, 

 dated 6th instant, containing the following account : 



" The second engine established in the mine called Yanacaiicha, 

 which is far superior in point of beauty, convenience, and size 

 to that called Santa Kosa, was set to work on Friday last, and 

 notwithstanding the great quantity of water which filtered into 

 this mine the engine with only half its power drained the mine 

 completely in nine minutes. This filtration did not happen in 

 Santa Rosa, on account of the quantity of hard copper ore on 

 which the engine is situated.
