long time to come. There are In tho Equator mine

first class ore Is hand-dresscd here aud sent to
Newark, New Jersey, Tor reduction. Tho second
class Is worked by Huepeden Co., in Georgetown
Eighteen tons Of first class ore sent to Newark
represented an average assay value OF $3.50 IN coin
per ton. After dcducing the expenses OF mining
hauling transporting and reducing and che per-
centage Of loss IN the manipulation, o handsome
profit Is secured. The second class ore has shown
an average assay value OF over $40 In com per ton
T1is Is reduced by Huepeden Co., whose works are
adequate to the present production OF the mine, and
are now being doubled In capacity TO meet the sntlc
pated Increase in the yield. During July and August
the supply OF ore being limited comparatively little
work was done. Between the middle OF July and
the lst OF August nfty-six tons Of ore yielded a
total OF $32os 90 In com, or an average OF sos So
