a eS HN February 10, 1872.] SCIENTIFIC PRESS. 95 WHY THE WILSON Patent Steam Stamp Mill IS THE BEST AND ‘Most Desirable Mill for Crushing Ores. Because the company give a responalble guarantee that the porchasers shall bo under no expense for repairs for TWELVE MONTHS, and guarantee the mill to cruxh (regular work) One Ton Per Hour of ths Hardest Quartz through the ordinary screens, THERE I8 A SAVING of from Twenty to Forty per cent. running expenses. To pnt one of tho Wilson Milla over tho mountain, from $10,000 to $18,000 Is saved in First Cost. The Wlison Mill will asve in working exponses and repairs enough every aix months to PAY FOR ITSELF. IN EVERY PARTICULAR This Mill is Greatly Superior to the Ordinary Oam @tamp Mill. RECOLLECT This Mill is Fully Guaranteed to do and be all we'claim for it, DO NOT BE DECEIVED by tho cry of ‘ Humbug,” but call and investigate ite merits, Ono can always be eeen at ths Pacific Iron Works. Ten of these Mills aro now in operation. For further partlcnlars addrese WILSON, Gan Francisco, FURMAN KE.
