1:08:01
another back breaking job
for the fire must not go out.
1:08:04
Night or day
1:08:05
either Pierre or Marie
had to be on hand all the time.
1:08:09
Dogged determination
kept them going
1:08:11
through month after month of
such arduous dangerous work
1:08:15
but even so
it began at last to tear on
1:08:18
both Pierre and Marie.
1:08:30
This was something they had to
fight continually
1:08:32
the gas fumes.
1:08:37
Eventually, months run into years
1:08:40
The kind of works changed
1:08:42
but Pierre had to build
1:08:43
or assemble their equipment
and with any material
1:08:46
that lay at hand.
1:08:48
What was left of
the original pitch blende
1:08:50
had now to be filtered and
1:08:52
re-filtered to
remove other elements.
1:08:55
And this work were not
quite so physically strenuous
1:08:58
was hard enough
1:08:59
specially during
the hot summer days.
1:09:04
And so the work went on
until presently
1:09:07
everything had been removed
1:09:08
from the tons of ore
except two final elements
1:09:12
one was barium and the other
1:09:14
which they had began to
think of it
1:09:15
in their heart
as their own element
1:09:17
was the precious illusive radium.
1:09:20
Pierre and Marie thought that
1:09:22
the end of their task
must surely be in sight.
1:09:25
All that was now left was to
separate these two survivors
1:09:30
barium and radium.
1:09:32
This was the problem to
separate barium
1:09:35
and radium somehow or other.
