NormanI herewith present to you the following as my graduating thesis. It consists of twenty eight pages of written matter and three plates ; the whole being a description of tests made for determining the best method of treatment for the ores of the Perigo Mine, Gilpin Co., Colo., together with the designs of the plant to be used. As most of my time was spent on laboratory work, the drawings are not what I would desire, but they may serve to give an idea of the nature of the plant.
