In addition, as mining developmentproceeded, it was shown that in many of these mines the silver-lead con-tents were gradually replaced in depth by zinc until, finally, in some casesthis latter metal became the chief constituent. As, however, its presencein excess of the smelters limit of 10% subjected such ores to a penalty of50 cents per unit, it can scarcely be a matter of wonder that in cases whereat all possible no mention was made of this metal as a constituent, es
