| Then Mr. Patterson offered that the
witness be allowed to explain the con
| ditions surrounding the displacement OF
| the porphyry dyke to the court Mr.
Hughes objected. The court sustained
| the objection and Mr.. Patterson took
| an exception.
Mr. Tyler. supposing the veins east
! and west Of the faults We're continuous
and Identical what would their mutual
| or general conveyance or divergenca
| or their strike indicate as to a crossing
| of the Veins at the east?" said Mr.. Pat
| terson.
1T might indicate curvature to the
south, but it would not necessarily in
dictate a crossing" said Mr.. Tyler.
The witness said that he thought the
| ore deposits would have gone up and
down definitely and regularly, instead
of being in the limited form they are
vertically had the broken area between
the faults been produced by a concen-
tratlon of ore through crossings of the
east and west veins and not by fault
ing.
The witness said that the samples of
the defendants witnesses containins;
pebbles of ore were not taken from
veins or parts of veins or opposite veins.
but from the crevices of the faults
themselves.
Have you any knowledge of a geo.
logical law whereby mineral solutions,
passing through fissure. will mineral
ize some pebbles and omit others?'
asked Mr.. Patterson.
II have not" said the witness.
Have you any practical experience
Of such a thing?"

State whether the atmospheric water,
falling upon such surfaces as our foot
hills and mountains here present, con-
tains sufficient organic matter to rede-
post oxidized sulphides in the form of
sulphide ore.
1T does not
estate whether this is the rule as to
atmospheric water, or the exception"
1T is the rule"
What do we understand by organic
matter?"
1T is vegetable or animal matter I'M
der process of decomposition
Mr.. Patterson read a quotation from
a geological work, in which the writer
says that certain agencies do not pre-
cipitate sulphides, but attack and de-
COMPOSE them.
DO you agree with the writer in
this?' asked MI Patterson.
II do" said the witness.
"What is sulphuretted hydrogen?"
1T is a chemical element composed of
two atoms of pyrites and one of sui
phur.'
In what way does it usually ex-
ist?"
I'm connection with sulphur springs.
The water of such springs brings sui
phuretted hydrogen gas to the surface
with it usually"
IF there We're sulphuretted hydrogen
in this ground, how would it be mani
fested?'
1T would exist in connection with the
underground waters and its smell would
make it known"
state the difference between an
oxidizng agent and reducing agent"
"The first decomposes the substance
acted upon and takes it up in solution;
the second reduces or precipitates
chemicals already dissolved"
What are the characteristics of the
waters forming the two agents?''
In order to be a reducing solution,
water must contain an excess of or
ganic matter: if the organic matter is
in less quantity, the water acts as an
oxidizing agent. The two cannot exist
at the same. time. If there is an excess
of organic matter in the water the
oXidizing property is overcome by the
reducing property"

a geological work read by MI Hughes
