mills as follows:
There are two reasons why stamp
mills are used more than Gillian mills
for crushing gold ores. First on ac-
count of the character of the work
they do, and, second, on account of the
cost and ease of repairs. Under the
| hrst head 1t may be said that the
stamp mill produces a sharp, angular
! product In which the precious metal
| is usually freed but not ground to an
impalpable powder, while the Gillian
mill, owing to the slipping of the rollers
| on the dies, grinds much of the ore to
an impalpable powder, and this is IL
able to cause more or less of the ma
| terial to wash away, without becoming
| amalgamated. Under the second head
| may be considered the difference in
construction. The stamp mill is COM
| posed of comparatively small wearing
| pieces, which are easily and quickly
| replaced and repaired. so that it forms
| an almost ideal machine for use in out
lying districts which are difficult Of
| access, while the heavy tires and dies
| for the CHILEAN mill are hard to place,
! heavy to handle and difficult to trans
port, and N many cases difficult to
| obtain. All these facts taken into con-
| sidera ton have acted in favor of The
stamp mill for the crushing of gold
| ores.
In 1898 there were 45 dividend paying
gold mining companies in the Trans
vaal, South Africa; the dividends ag-
gregated s5,0s9,7s5 The number of
non-producing gold mines in that dis
trict last year was 40. The mines total
expense was e10.961,S12; the output
| was G16,240630. OF this amount the
Rand contributed 1920 per cent. The
| relative expense was as follows Sal
aries and wages to whites, 1882 per
nI
per cent; explosives, 11.S5 per cent.
| fuel, So per cent; building material,
| SS1 per cent: iron, tools. shoes and
dies. lubricating, betting. etc. 4.31 per
cent; chemicals. 1926 per cent; light
ing, 1.29 per cent; animal food, .32
per cent; sundries, SO per cent; total,
| 100 per cent. The average yield per
ton of ore milled was 27.14 shillings.
There were 9034,79 tons extracted:
the mills crushed 1861 ,OS9 tons of ore.

The lease and bond recently secured
upon the Silver Key property at Park
City is apt to cut more of a figure In
| the operations Of the camp than APP
pears on the surface. Up to now 1t has
been supposed that James NJ. Kennedy
| was the lessee and that he had taken
hold of the mine simply to work it for
the ores it contained. 1t transpires,
| however, that S. V. Shelp, manager of
| Walker Bros store, and others, who
are supposed to be acting for the Walk
| ers, have a lease and bond on the group
| of nine or 10 patented claims, consti-
| tuting the Silver Key company's hold
ings, and that a plan of extensive de-
velopment work is now being perfect
| ed for the winter months. There are

City seems to be better than it has in

Gold pockets occur under many con-
ditions-in black slate, in tale, in dia-
| base, at contacts, in limestone and in
diorite, but usually where two or more
veins or seams converge. There are
usually three separate assures. crevices
or veins. First is the vein of quartz
| proper. This is usually barren except
where the pockets occur. Next is the
| crossing-a seam or small vein or
| crack-cutting across the vein, and the
third the gold seam. the latter being
important. 1t strikes nearly parallel
with the vein and dips toward it.
Where these three unite the pocket of
gold may or may not be found. The oc-
currence of pockets is very uncertain
under any circumstances; and, al
though the searching for pockets has
| Deen reduced TO almost a science, the
element of luck is an important factor.
G.. S. Batterman, one of the best
known mining men in the Rocky
mountain states. was on the stand as
an expert in an important mining case
in Nevada and was under cross-ex-
animation by rather young and
Smart attorney. The question relat-
ed to the form that ore was found in,
generally described as kidney Jumps"
Nov, Mr.. Batterman," said the at
torney, how large are these Jumps
you say they are oblong-are they as
long as my head?" Yes" replied Mr..
Batterman, but not as thick" The
attorney subsidized, and even the Judge
could not help smiling.-Pittsburg Die

The negotiations between Joseph Lei
ter and the owners of 10 asphaltum
| claims in Rio Blanco county, Colo, near
the Utah line, have fallen through
Mr.. Letter had an option on the claims
for s15O,000, but 1t expired on the 14th
and will not be extended. The Letter
| syndicate, however. has completed the
purchase of so asphaltum claims on
the south side of the Uintah reserva-
ton, in Utah, for $25,000..
The claims are undeveloped. 1t is
learned that another eastern syndicate
is after the Colorado asphaltum lands
upon which Letter held an option, and

closed up within few days.
Conditions are reported to be very
| prosperous at Ely, New. The Chain
man and Robust mills are both run

The Chairman is being operated by
Salt Lake parties. New York parties
are reported to have tied up nine cop
