A recent test OF the capacity Of the
Miami mill was surprising in its re-
suits. in that il showed that 755 tons
had been run through the unit used for
tho purpose, and demonstrated that
each unit of the mill will be able TO
handle 200 tons daily or twice the
amount originally estimated as the ca
pacity Of the mill, or 1000 tons for the
six units.
Two cars Of concentrates, averaging
so tons per car, were shipped TO the
Cananea smelter April II, and another
car Of so tons was sent. out April y.
The manner Of impounding the tall
ings is an ingenious as well as eco
nomical one A trough containing out
let's at regular intervals in its bottom
is built across the mouth of the arroyo
at a height that will mark the top of
the dam. The tailings from the mill
flow through this fume and are dis
tributed evenly by means Of the gate
controlled outlets The result is
steadily rising wall of tailings that in
time will be a wall fifty feet high be-
hind which the tailings of the concen-
traitor will be held. Because of the
height of the mill above the bed of the
canyon the wall can be raised as need
ed almost indefinitely
Unit No. 4 is ready for operation and
will begin handling ore as soon as COM
pletion Of the mechanism controlling
the ore pocket in the mine is COM
plete. 1t is equipped with Burch rolls
instead of the Chilean mills through
which the ore passes before entering
the units. Until the Burch rolls are
tested it will not be known whether
units . and 6 will be equipped with
Burch or Chilean method. From the
fact. however, that the Burch primary
rolls that first handle the ore that lat
or enters the Chilean mills above UNI
its 1, and 3. seem wholly satisfac-
tory il seems almost certain that il
viii be used also for the remaining un-
It's.
President Deister, OF the Deister
Manufacturing company. who is super
vising the installation and preliminary
operation Of the Deister tables and
concomitant mechanism. says the mill
as a whole is almost perfection. and
that too much cannot be said in praise
OF the thoroughness of equipment and
precise operation Of the plant.
At the Inspiration property moth

at present. Underground development
and churn drilling from the surface
are being carried along at their GUS
tomary gait. but until the Joe d, u.|
generator. the Ball high-speed eener-
ator engine, the two electric Iocomo-
tives for underground hauling, and
other integers Of the proposed equip
ment are on the ground it viii be inn

gress at the mine.
Despite the fact that il seems the I
Compauys intention % build their con- /
centrator at Wheatdelds. such "a pro- /
Gram fails to gain public belief That .
the Inspiration would haul its low
grade ores more than ten miles from /
the mine in preference to pumping wa
ter TO the latter seems incredible. /
However, the preliminary steps for
placing the concentration at WhoatfeIdsI /
seem TO be in progress. A two-mIIe
wagon road connecting the proposed
site Of the concentration with BAH G.
Pringle's road, and thus with the main
high road between Whcatfcls and I
Miami IS being constructed, aud con-
siderable preliminary surveying both |
by the railroad and the Inspiration |
company has been done.
