THE HEINTZLEMAN SIiEVE.
Cross, we started on a visit to the Cerro Colorado mine,

At that time the main shaft had reached a depth of one hundred and twenty feet, and the ore seemed to yield far better

yielded sixty dollars to the ton; at a depth of sixty feet it
had yielded nearly two thousand dollars to the ton; and an
