stand yesterday in the trial of the min
ing suit of the Colusa-Parrot Mining Co.
VS.. the Anaconda Copper Mining Co.
Mr.. Macfarlane said he was at present
a resident of Salt Lake. He had made
several careful examinations of the
ground involved in the present contro-
/ versy and had been familiar with the
ground for the past IA years. The wit
ness began by tracing the outcrop of the
| various big veins on the hill. Their he
described the workings of the Colusa-
Parrot, especially the four veins which
had been referred to by Mr.. Sizer as be-
ing in Colusa-Parrot ground.
The ore body at the 900 level of the
Colusa-Parrot No. 10 raise had become
the hanging wall streak of the Anaconda
vein. On the same level vein No. 2 Of
theC olusa-Parrot could be found in raise
No. l and vein No. 8 could be traced in
the old workings above. At the 1000
level the identity of veins Nos. l and 2
had become lost in the Anaconda vein,
but No. 3 vein was traceable eastward.
Vein No. 4 at this point was the main
body.
On the 100 level Mr.. Macfarlane said
that the -four veins of the Colusa-Parrot
became merged into the Anaconda vein.
The witness followed the various bodies
from the upper levels down to the deep
est workings, through the various raises,
and claimed that there was undoubtedly
a union of the Anaconda and Colusa-
Parrot veins He had failed, he said to
discover any blue or fault vein but he
had discovered clay seams within the
ore bodies of the Colusa-Parrot. Some
of these seams appeared to cut off the ore
but they did not as ore had been found
on either side of all of them. h was
shown at the 600 of the Never Sweat, and
again in the Ramsdel-Parrot where the
Colusa-Parrot vein had been found some
500 feet farther east.
On Characterization by Mr.. Vaile the
witness reiterated his belief that there
was a union of the two vein at depth.
He was questioned relative to the fs-
sure theory of the defendants and was
taken all over the ground from the sur.
face to the 1900 foot workings, but Mr..
Macfarlane commended that there was a
continuous connection between the ore
bodies.
The cross-examination of Mr.. Macfar-
lane was continued his morning, occu-
plying about half an hour. It was con-
Quoted by Mr.. Vale, the impetuous
ner of the attorney being in marked on
trast to the deliberate manner of the
mining engineer. Mr.. Macfarlane con-
tended that the No. 2 ore body connect
ed with a wide stope at the 500 level of
the Colusa-Parrot. Mr.. Macfarlane adj
mitted that the plaintiffs assays showed
that for a distance of 50 feet north of
the Colusa-Parrot shaft there was no
commercial ore. The ground, however,
he said, was mineralized to some extent.
South of the shaft for a hundred feet
or more the witness admitted tha the
samples showed no commercial ore.
Prof. George Washington Tower, Jr.,
followed Mr.. Macfarlane. Professor
Tower said he had graduated from the
geological department of Harvard in
1895, and after finishing his course had
worked in the United States geological
survey, in the Aspen, Butte, Tintic and
Black Hills districts and in the San Juan
mountains of Colorado. He had, been in
the employ of the United States for four
years, his duties being to make exam
nations of mines and reports of a scien-
tific nature of the same. He had spent
about six months examining the princi-
pal mines of Butte.
In May of 1899 he severed his connec-
ton with the survey, and since then has
been engaged in the mines of Butte
principally the mines of the Montana
Ore Purchasing company and of w. A.
Clark. He has also made several trims
to Utah and Arizona and to various por-
tons of the state. He first became
familiar with the ground in controversy
in May. 1899. when he made an examina-
ton for the purposes of this LITIGATION.
III all ne raS spent some so or GO DAYS
underground. studying the connecting
properties. the Anaconda, Never Sweat,
Colusa- Parrot, Salisbury and other
mines.
Professor Tower stated that he sur
race lines of the ground in LITIGATION had
already been gone over pretty thor
oushly. The Colusa-Parrot and Ana
conda lodes. he said. We're clearly trace
able on the surface. He hough he
Colusa-Parrot one of the best apexes in
the district. His testimony from this
point on related largely to the assure
system of the ground. The most i'm
portant assures. he said, were the east
ana west ones. as they We're generally
the ore channels :Ad the courses of the
greatest ore bodies. There were two
groups OF east and west fissures-th.
Anaconda and Colusa-Parrot. Their
general dip was southerly. The fissure
seen in the railroad cut betwee the
Never Sweat and COlusa- Parrot was also
seen in No. 5 raise and other workings
of the COlusa-P Parrot. There was a
northwest assure system also, but not
as persistent as the others. He de-
scribed some of those he had noted. On
the 2OO-fOot level of the ColuGa- Parrot he
had found one assure Just west OF the
No. 4 raise. This {issure had a north-
west strike and a dip of about. Is degrees.
another assure had been noted in the
No. 5 raise south from the Never Sweat.
ihere were several others on the san
level.
On the 300 level a fissure was shown at
the NO. 5 raise n another on the east
or the No. I raise. On the 400 a strong
insure was noted southeast of No. 4
raise. Another one east of the No. s
