and Blue Vein.
DECIlNED TO TnEORlZE
Harvard Man Followed BY Manager

ingt0n.

Prof. N. s. Shaler followed Mr.. King
on the witness stand yesterday in the trial
of the mining suit of Colusa- Parrot VS..
Anaconda Mining Co. He gave his resi-
dence as Cambridge, Mass, and his pro-
fession as hat of teacher of geology at
Harvard, a work in which he had been
engaged for 40 years. He said he had,
also been state geologist of Kentucky
and president Of the American Geological
society. He had been in Europe about
four years and been interested in Madi-
SON county. Montana, for about three
years. He hau been in Butte about 30 or
40 days altogether. In July, 1898, HI a
begun his examination.
Prof. Shaler said that he had studied
sections of Butte's underground world
and had carefully examined building ex-
cavatiOns, railroad cuts and excavations
for sewers. In all he had examined be-
tween 1900 and $4,000 running feet. The
country arOund the Butte district, he
said, vas laced with veinlets, with an
average Of n veinlet to every three and
a half feet. and one large or not noticeable
vein every 10 feet. He was satisfied
that the whole country hereabouts was
mineralized. He had found but one Sec
ton of SO running feet that had contained
no vein.
The professor aid his Investigations Of
this district had extended from the con-
tinental divide on the east to the Blue
Bird mine on the west and from the Alice
mine on he north to the fiat on the
SOUTH, the latter at one time having been
a lake. His examination Of the A%nacon-
da mine was made with a view to solving
the problems of ore deposits. In the
granite rock which is very widely miner
allied there are many veins running east
and west. The Anaconda and Colusa-
Parrot veins belong to the latter group.
He agreed with Mr.. King that there was
some difference between the two veins.
The mineral deposits in the Anaconda
vein, he said. ave an exceptional contin-
uity. He had made a minut examina-
ton of the workings and found the vein
uniform throughout. The professor said
that intJuly, 1899, he became ware OF the
! presence of another great vein of differ
ent structure which has since been
known as the diagonal or blue vein. He
made an examination of this vein and
found 1t to be a huge brecciated vein,
full Of fragments of granite and the walls
heavily grOOved, showing diverse motion.
This vein formed a splendid passage for
water, unlike other veins of the district.
Its most striking feature was the large
quantity of clay It contained. His de-
auctions were that this vein was a huge
fault which separated the Anaconda and
COlusa-ParrOt veins which originally
had been n and the same vein. He
was satisfied of this because this fault
fissure was ound in the Nipper to the
northwest and extended as lar as the Lit
! tie Minah. It was noticeable also sew
eral miles southwest of Butte where d.
rectly in line with the main fault of the
Anaconda can be seen a lault, which can
be traced for several miles.
Prof. Shaler admitted that the blu or
fault vein was very irregularly MINER
allied and in sharp contrast to the Ana
conda, but he believed that the veins in
controversy were one and the same at
one time. Asked to describe a fault, the
professor said it was a break in the rock,
the left side Of the fractured area being
higher than the other. The vein hllin9
| largely consists Of great slivers of u
try rock and peculiar quality of clay. 1t
might contain some ore, which could get
there by natural replacement from the
broken faces of the once united vein.
Prof. Shaler said that during his ex-
