MEXICAN MINES. 



By the last accounts from Mexico it is learnt that the adit on the 

 great Biscaina Vein at Real del Monte, is cleared to a point where a 

 stream of water coming from the western ground has been intercepted, 

 and instead of falling to the deep parts of the mine, it will now be 

 carried off. It is proposed also to employ the power which may be 

 derived from this water, to drain a part which is expected to be pro- 

 ductive, and at present out of the reach of the steam engines. This 

 will be done by one of the hydraulic machines called pressure engines, 

 which it is ascertained can be placed there, and may relieve this part 

 of the mine from water sooner than other means which are pursuing.
