What is your opinion based on?"
asked Mr.. Hughes.
Upon my knowledge, sir said Mr..
Akers. m
Where are the projections on the
map dangerous or improper?"
Where they indicate that a stope
crosses fault, creating the impression
that the ore extends across the fault,
when it does not"
What fault does the cross section
cut2"
1T cuts both, SIR" e
The witness explained that the cross
section was automatically correct,
and that projection is proper, though
sometimes dangerous.
A plan map of cross sections was
hung up, and the witness described the
section of the country cut by cross
section K.
Asked if he would describe the zone
between the faults as starting with
very fine material at the east fault
and shading off into solid rock to the
west, he said he would not.
He said that he had approved of the
coloring of the defendants maps, and
the cross section of the Lloyd tunnel
was pulled down.
How much of the porphyry on this
section is protector" asked Mr..
Hughes.
Very little in the upper part, SIR"
said the witness.
He described the parts Of the por-
phyry that are disclosed in the work.
ings.
"And all the rest of it is projected,
Is it?" asked Mr.. Hughes.
cred from other places" said the wit
ness.
A couple of other cross section maps
of the defendant We're hung up, and
the witness said that certain parts of
the porphyry shown upon them were
projected. The 700 level map, showing
body of porphyry east of the east
width of 25 feet. was brought out.
There is not a working in the
ground showing that porphyry, is
there?" said Mr.. Hughes.
mo. SIR
And it is not projected from any,
where else, either, is 1T"
oh yes, sir; it is.
From where?"
"It Is farther west"
The witness explained where the por-
phyry is that furnished base for the
projection.
How long is the body of porphyry
on the 500 leveI?" asked Mr.. Hughes
"One, two, three, four hundred. Four
hundred and fifty feet, if you like" said
the witness.
Are there any workings that show
it?"
mo. sir
Are there any dotted lines or other
conventional signs to show that any
of this perphyry has been projected?"
asked Mr.. Hughes.
mo, sir; there has been no attempt,
sir, to use conventional signs. In this
case they would be entirely superflu-
ous"
do not engineers use dotted lines
to show protection"
Yes. SIR
why are they not used here?"
Because, where there are no work.
ings, projection is understood"
Then what is the difference between
this and plaintiffs cross section K
map?'
I'm that map the red lines showing
veins are drawn through workings"
How is that?"
They pass diagonally through verti-
cal workings"
THE workings are vertical, and they
are diagonal Are they in workiags?"
Yes, sir; they pass through workings
diagonally.' ..
The witness stated that the measure
ments of the ore bodies between the
faults that he gave Mr.. Patterson Fri
day were intended to show the ex-
not purport to show the continuous
extent.
Are there not broken and crushed
timbers that intercept passage through
| the workings across the west fault?"
asked Mr.. Hughes.
Yes, sir" said the witness.
Then. the crushing is not confined
! within the faults?"
"Oh, no, sir: not entirely"
How far does the crushing extend
on the powder vein on the ass level?"
| For 200 feet
There is a closing of the drifts on
| two or three other levels for dis
| lance of 100 feet or more west of the
| west fault.
The witness testified that the ground
| is all so heavy that when a working
| is once crushed it is very difficult to
| find. He has spent hours trying to
determine the existence of a working
| that had become closed. This is true
of the ground west of the faults, as
well as that within them. 1t had pre-
vented Mr.. Akers from making ex-
animation of many old workings.
The redirect examination of Mr.
Akers was taken up by Mr.. Patterson.
will you explain the difference be-
| tween the zone between the faults and
that outsider" asked Mr.. Patterson.
| The ground between the faults is
| much crushed and broken as a mass,
| and the granite is much altered" said
| the witness.
The witness said that the proportion
of crushed timber between the faults Is
very much greater than that outside.
! He said that the makers of the de-
PENDANTS maps were entirely warranted
in making the projections of porphyry
| that they had made, under the rules
