Josuua Henpr, Esq.—Dear Sir :—I take pleasure in cerlifying to the cfficiency of the two last Concentrators ordered trom you. We havertn them steadily since July last, with but a very trifling expense forrepairs, The additional length of step is a devided improvement. The first six sent to us have run stcadily for nearly nine months, and are still doing good work. * # * The concentrations from the eight pans alone much more than pay our entire surface expenses. Without them we should lose a large proportion by any system of concentration now in use, The eight Concentrators receive the pulp from our 24 stamps, which are crushing 1,040 tons per month. Our sales of Sulphurets last month amounted to 70 tons, or nearly 7 per cent. of the mass crushed. The sul‘. phurets from the reconcentration, contained about 10 per cent. sand. In addition to their properties as concentrators, they baye done us good service as amalgamators, they having saved us the past month 50 ounces of hard amalgam, worth £350, which otherwise would have heen lost.
