OCR Page 1 of 5January 19, 1917.
On January 16th I arrived at the General Electric
Company's plant at 8:30 and ment immediately to the office
of A. H. Hinman, Purchasing Agent. Mr. Hinman was not in
town, but I consulted his secretary who learned from Mr.
Hull, one of their other purchasing agents that the matter
of luminous material, according to their records, had been
dropped.
Upon careful inquiry I found that they had en-
deavored to loeste our names on the files. I found the
Radium Chenical Company's neme on the list and that they
mere evidently purchasing material from then. They in-
formed us that the Engineering Department forwarded the
necessary information to them and then purchased upon re-
commendation received, but as soon as a concern ceased to
be in line for competitive business they took the name from
the files and transferred it back to the Engineering Depart-
ment where it originated. I found a record of this transfer
on September lst, 1916.
I then visited Mr. W. S. Andrews who was extremely
courteous and informed me that to his knowledge only fifty
of the luminous pendents had been manufactured to date. Mr.
Andrews showed me very many interesting things in his labor-
atory and presented me with samples of fused Wilimite together
with a vacuum tube containing a small amount of mercury and
neon. This tube is a demonstration of the slight amount of
electricity needed to produce light in neon atmosphere By
shaking the tube the mercury generates electricity and the small
amo'unt of electricity makes the neon highly luminous.
