" Contract. 



"1st. The present contract shall be considered binding for 

 nine years, to be computed from the time the steam-engines 

 may be erected in the different parts of these mines that may 

 be judged suitable. 



"2nd. The miners herein contracting cede their mines in 

 Yauricocha, Yanacancha, Caya Chica, Santa Rosa, and in the 

 mining ridge of Colquijilca, and the company offer the means, 

 steam-engines, and instruments for draining the same, and on 

 these principles the obligations of both parties are as follow, 

 to wit. 



" 3rd. The company binds itself within the period of 

 eighteen months, or sooner if possible, to bring over the steam- 

 engines to drain successively the different parts of these mines,

 and afterwards in Yanacancha, Caya Chica, Santa Rosa, and in 

 the mining ridge of Colquijilca, to sink a general pit for the 

 collection of the waters at a depth of 40 varas from the adit or 

 drainage level of Santa Rosa. 



" 8th. Each miner whose mine situated in the parts above 

 specified is not perfectly drained in consequence of the filtration 

 or natural gravity of the water to the general pit, is to continue 

 a tube to communicate with the said general pit on his own 

 account, in order fully to enjoy the benefit of the draining, it 

 being well understood that the company shall not refuse to 

 admit the waters of any of the mines situated in this part what- 

 ever their quantity may be. And the company shall be further 

 bound to supply funds to any miner who may not have suffi- 

 cient to defray the expenses of such tube of communication at 

 an interest of 6 per cent., to be refunded out of the first metals 

 which may be obtained. 



" 10th. The recompense to be made to the company for the 

 general drain procured in the place or places agreed on, shall 

 be, with regard to Yanacancha and Yauricocha, in consequence 

 of the known richness of those places, and of the timber required 

 by the softness of the ground to secure the mines, 15 per cent, 

 on the ore that shall be extracted therefrom, and lodged either 

 in the common depots or in the respective warehouses ; and in
