oxidizing waters, for if they had they
would have oxidized the ore below"
rs it your opinion that wherever you
find the top of the sulphide ore you
| have proof that no water from the sur
| face has gone down deeper than the
top?"
Yes, sir. I don't believe that it has
gone any deeper than the permanent
water level
Where does the water go when it
reaches this level?"
| Il account for it by drainage"
| ut flows off?'
Yes, sir; it flows off"
| Let us understand this. Do YOU
hold that when the water from above,
| trickling down slowly, reaches the
water level, it finds the rock saturated
at that level. or the water standing
stagnant in the assures THEREOF
Both. If the surface water trick

MI Hughes read an authority upon
Underground waters which said that
the water below the water level is not
stagnant, and that it is continually
passing downward through the rocks
by capillarity. Mr.. King said that the
authority was admirable. and agreed
with it. But he explained that the
| movement by capillarity is very slow
and the waters are practically stag
nant.
rs the water from above just as ca
pable of oxidizing the ore below the
water level as above, I'd like to
know?" said Mr. Hughes.
1T would be sometimes, and some
times it would not said the witness
Two glass plates with ore samples
| affixed to them were submitted to the
witness. He said that he could not see
what the ores were very well, but
thought they We're ores of certain
| character. Mr.. Hughes asked if they
We're not samples of two depositions
one or the other, and said that re
wished to show the court what was
meant by two dispositions. Mr.. King
said that they We're, as nearly as he
could see, such samples, but he did not
regard either as secondary. He had
testified that there have been several
primary dispositions in the east and
west veins, and he thought these We're
| two of them.
What conditions would you require
! to prove secondary deposition" asked
Mr. Hughes.
Il can't say; I don't know what
traces nature would leave" said a!r.

Then you could not tell detective
what to search for?'
| No"

Mr.. King said that he had seen up
per sulphides upon a layer of lower
| ores on the line of the permanent
water level in copper mines.
| rs there not sulphuretted hydrogen
in the underground waters some
times?" asked Mr.. Hughes.
Yes" said the witness
DO not copper pyrites form in I'M
foreground waters when organic mat
ter is encountered?"
Yes"
Then if sulphates of copper came in
| contact with organic matter in the wa
ter, would not sulphide ore be formed ~
IF the copper sulphates in the water
| trickling downward met with organic
matter in sufficient quantity and on a
| permanent level that might happen"
Then. you must be taken as an anti
| redepositionist below the permanent
water line I'm to understand"
Yes, sir"
