"Our greatest consumers of platinum are the electricians, particularly the
incandescent light companies. I supply the platinum wire for both the
Edison and the Maxim companies, and the quantity they require so
constantly increases that the demand threatens to exceed the supply of the
metal. Sheets of platinum are bought by chemists, who have them converted
into crucibles and other forms."
The reporter's curiosity was awakened by Mr. Baker's mention of the old
lady who made those very fine draw plates, and on his return to the city
he hunted her up. Mrs. Francis A. Jeannot, the lady in question, was found
in neat apartments in a handsome flat in West Fifty-first street. Age has
silvered her hair, but her eyes are still bright, and her movements
indicate elasticity and strength. She is a native of Neufchatel,
Switzerland, and speaks English with a little difficulty, but whenever the
reporter's English was a little hard for her a very pretty girl with
brilliant eyes and crinkly jet-black hair, who subsequently proved to be a
daughter of Mrs. Jeannot, came to the rescue. With the girl's occasional
aid, the old lady's story was as follows:
"I have been in this business for thirty years. I learned it when I was a
girl in Switzerland. Very few in this country know anything correctly
about it. Numbers of people endeavor to find it out, and they experiment
to learn it, especially to do it by machinery, but without success. But,
ah, me! It is no longer a business that is anything worth. Thirty years
ago many stone draw plates were wanted, for then there was a great deal
done in filigree gold jewelry. Then the plates were worth from $2.50 up to
as high as $15, according to the magnitude of the stones and the size of
the holes I bored in them. Now, however, all that good time is past.
Nobody wants filigree gold jewelry any more, and there is so little demand
for fine wire of the precious metals that few draw plates are desired. The
prices now are no more than from $1.25 up to say $8, but it is very rare
that one is required the cost of which is more than $4. And of that a very
large part must go to the lapidary to pay for the stone and for his work
in cutting it to an even round disk. Then, what I get for the long and
hard work of boring the stone by hand is very little. 'By hand?' Oh, yes.
That must always be the only good way. The work of the machine is not
perfect. It never produces such good plates as are made by the hand and
eye of the trained artisan. 'How are they bored?' Ah, sir, you must excuse
me that I do not tell you that. It is simple, but there is just a little
of it that is a secret, and that little makes a vast difference between
producing work which is good and that which is not. It has cost me no
little to learn it, and while it is worth very little just now, perhaps
fashion may change, and plates may be wanted to make gold wire again to an
extent that may be profitable. I do not wish to tell everybody that which
