If you have old boilers, whims, steam hoists, donkey engines or other mining machinery, or ap- paratus that is in good order that you want to sell, advertise them in the Mining Review. If you want such articles advertise for them in the Mining Review. exhibit-openin- e, sub-jecti- ng K,rire Brick CHUR, - Agent, York. The mining academy of Prof. H. Hirsching is now open. Every mining man should take a course of study in natural sciences, lixiviation and electrolysis m this institute. The catalogue provides a special course for the study of lixiviation and the electrolytic processes, and is therefore of great importance to our mining people, who desire to extract metals from ores by cheap processes.
