■ a The Method of Cleaning up Gold. — c [n the mode of cleaning up and securing a he gold from the riffles and sluice-boxes, o md the treatment by the quicksilver and •■ litric acid processes so well known to r niners, the final residuum, after obtaining „ ;he amalgam and the treatment with acids, a s usually thrown away, under the impres- I don that all the gold has been secured. J But Mr, E. R. Chapin,of this city, while ° manager of the Columbian Fluming Com- c pany discovered that this was not the fact ; a but that if the acid was slowly evaporated, f guile a large per centagein addition might * yet be secured. This course he followed with the most gratifying; results. That d company saves enough, in this way, every s year, to pay the salary of their superin- o tendent. To illustrate how important an g item this is in the : process of cleaning-up *' we will mention two. or three cases, all the ? acts of which we know as recent. TheE. s Xi, Hunter claim, in the residuum of which J/AOO dollars had been taken, 385 dollars ii vas found afjter evaporation ; the Sawmill ° ?lat Company saves 1,000 dollars a year ' tnd My. Hawes, in his claim up Matelot v iulch, secures from 300 to 400 dollars.— k 'Jolumbia Courier. t
