and Don Tomas Gal legos ; and lastly, Mr. Bull, and all those 

 associated in this great work, whom you recommend to my 

 notice. Your Lordship, by having exerted yourself to facilitate, 

 by all the means which your zeal and authority could procure, 

 the happy consummation of so profitable an enterprise, has 

 added a new claim to the many preceding which you possessed, 

 to the high consideration of the king and the public.

Extract from the 'Lima Gazette' of the 25th of September, 1816. 



" We have the satisfaction of communicating to the public 

 the information that the company for draining the mines of 

 Pasco have just received accounts from their agents in that 

 mineral territory ; and they promise for our next Gazette a 

 description of the state of the works for fixing the remaining

 Santa Eosa Mine last Saturday, the 14th instant, at 10 o'clock 

 at night we began to act ; at 11 o'clock the pitmen went down 

 to clear the shaft, and have not since ceased working an

 remained at the bottom of the shaft, and clogged every moment 

 the buckets and suckers of the engine, lasted till Wednesday ; 

 but this being accomplished, at 12 o'clock at noon they began 

 to break through the level. At half a yard below the shaft we 

 found a lively coppery ore, with its particles of silver. This 

 bronze-coloured ore indicates that the veins of Yauricocha and 

 San Diego incline to the west, or towards the Santa Rosa Mine. 

 The mines in the vicinity of this pit are all dry. Some of them, 

 at the distance of 300 yards, in the ridge of Santa Rita, have 

 also felt its effects ; and even as far as the territory of Caya, 

 behind our steam-works, the waters have fallen in several mines. 

 Don John Vivas has begun to work in San Diego Mine. They 

 are also going next Monday to begin working in several points 

 of the Santa Rosa Mine. The pit is already 8 yards in depth,
