Mill Is Also Under
Way At Miami.

spiratiOn mill. whose floor area viii
be S27 by zoe feet, s inow being con
structed; the first concrete having now
been poured, although some prelfm-
mary work with the concrets plant
was tried two days before. 1t is prob
able that the exact dimensions and
nature of the details Of the mills
structure are unknOW as yet even to
the builders, the final outcome Of the
mill being necessary to base plans OF
detail upon.
Grading for the notation test mill
IS well under way and 1t should be
constructed within six months. Its
capacity will be 500 tons daily. AS
the Inspiration mill construction is
under supervision of chief engineer
H Kenyon Burch who was in charge
Of construction OF the Miami mill, IT
is generally thought that the new mill
will develop more than its proposed
capacity Of 1900 tons daily: for the
Miami mill. built to handle 1000 tons
handled 90 per cent more than that
during its first month Of operation
At the Inspiration. mine work Is
tagging somewhat underground be-
cause OF the general readjuStmenE

for concrete material
