scene that met our eyes! Oh, boy!

Yes, certainly, Miss ConnOr. II he

Madeline looked searchingly at

he told me at the hospital this morn
ing that II we three saw our chance
to work Unmolested to go aheai
without him. What do you say about
pushing the test at the Bureau of
Standards this afternoon"
1t was agreed to, and within an
hour the three found themselves ready
for work in the laboratory assigned
them at the Bureau OF Standards. They
sat around a small table, upon the
surface OF which lay the precious
chart and the triangle.
Boys" began Madeline, 'I wonder
II you fully understand what we are
fully working for? also wonder what
value you place upon the information
which you believe the chart and tri-
angle hold. am convinced that our
enemies think that the secret Of
transmitting the baser metals into
gold can can be extracted from this
triangle, which, as you know, was cut
out from the chart. A part OF it can,
but fathers final instructions to me,
lead me to believe that / alone have
the knowledge TO create the entire
chemical formula to complete the
chart.
''EOw, you will recall. that the other
day we treated the chart from which
the triangle was cut. The chart,
which is made Of the finest long
fbred asbestos paper, specially treat
ed to increase its tensile strength, has
been impregnated with certain sub
stances, which,, when submitted to
particular chemical reactions and
treatments. will. give up much OF the
secret. We heated the chart in an
electric furnace kept at a tempera-
ture Of 24O degrees for .one-half hour
and then boiled ii in liquid air for
one hour to oxidiZe il. The chart then
placed in the safe was perfectly void
of any visible characters, as the
emersion in the Potomac had washed
away any characters that were
soluble to water! 1t thus appears that
the triangle would have no tale for
US, but it has, partially. The radio
activity that took place during its
ten hours exposure has ihdeIibly
burnt in certain characters, which.
when deciphered, will help us solve
our problem. 1t remains for US to
develop this chart, as you would d

Turning to the delicate apparatus
already set up, Madeline hastily in
spected IL. made a few minor adjust
ments, and placing the chart in a
holder between a telescope sight,
fitted for flter screens, and a small
glass tube containing the radio
active substance, she asked Hender-
son to turn out the electric light.
Cautioning the men to shield their
eyes and bodies behind a special
screen, She closed. a knife switch,
and with a sputter the glass tube was
