gh Mr. Moore did not meet with the exciting adventures of some
subsequent explorers, he encountered numerous difficulties and novel
experiences in his many months of travel through the hinterland of Japan
and China. The attitude toward foreigners thirty years ago was not as
friendly as it has since become, but Edison, as usual, had made a happy
choice of messengers, as Mr. Moore's good nature and diplomacy attested.
These qualities, together with his persistence and perseverance and
faculty of intelligent discrimination in the matter of fibres, helped to
make his mission successful, and gave to him the honor of being the
one who found the bamboo which was adopted for use as filaments in
commercial Edison lamps.
Although Edison had satisfied himself that bamboo furnished the most
desirable material thus far discovered for incandescent-lamp filaments,
he felt that in some part of the world there might be found a natural
product of the same general character that would furnish a still more
perfect and homogeneous material. In his study of this subject, and
during the prosecution of vigorous and searching inquiries in various
directions, he learned that Mr. John C. Brauner, then residing in
Brooklyn, New York, had an expert knowledge of indigenous plants of the
particular kind desired. During the course of a geological survey which
he had made for the Brazilian Government, Mr. Brauner had examined
closely the various species of palms which grow plentifully in that
country, and of them there was one whose fibres he thought would be just
what Edison wanted.
Accordingly, Mr. Brauner was sent for and dispatched to Brazil in
December, 1880, to search for and send samples of this and such other
palms, fibres, grasses, and canes as, in his judgment, would be suitable
for the experiments then being carried on at Menlo Park. Landing at
Para, he crossed over into the Amazonian province, and thence proceeded
through the heart of the country, making his way by canoe on the rivers
and their tributaries, and by foot into the forests and marshes of
a vast and almost untrodden wilderness. In this manner Mr. Brauner
traversed about two thousand miles of the comparatively unknown interior
of Southern Brazil, and procured a large variety of fibrous specimens,
which he shipped to Edison a few months later. When these fibres arrived
in the United States they were carefully tested and a few of them found
suitable but not superior to the Japan
