to assume that not over one.eirhth of
the output is lump ore. The fine orc is

licenses or stringers of ore ground will

one yard of ore to three, four and five
yards of dirt. / have it from an old and
experienced miner that he is TODAY, on
the Cripple Creek ores, washing from
fourteen to sixteen yards of dirt to get
one yard of ore.
In browne ground, we can make no
calculation whatever of even the an.
proximate output of orc from a given
area. What to-day may be breast of
first-class ore ground NAV next week be
cut out wholly or in part by horses of
clay, of varying size, either to be left
standing or removed as deads.
Extraordinary local variations in
phosphorus and manganese take place.
i have in my own present experience an
illustration of this. An open cut work
ing on a hillside was giving good wash
ground. say one to three, and was
normal in phosphorus and manganese
"A shaft sunk some distance back of this
working went through thirty-five feet,
vertically, of high-grade ore ground,
yielding rs per cent. of ore. The per-
centage of iron ran up to "a per cent,
silica under per cent but phosphorus
up to 2.13 per cent. and manganese l. "a
per cent. One hundred feet back of
this ON the same line, the ore gave 46
per cent. of phosphorus and BIS per
cent. OF manganese.
