Wickham saw that there were difficulties that would prevent the
gathering of wild rubber from keeping pace with the growing
demand. Although millions of rubber trees still stood untouched in
the Brazilian forests, only those trees near the river banks could
be tapped because of the impossibility of getting the rubber out
of the dense vegetation. Life in the jungle was dangerous and
lonely, and therefore rubber gatherers were not easy to find. They
were compelled to work far from their families and friends, and in
constant danger from wild beasts, reptiles and death-bearing
fevers. It is no wonder that rubber obtained in this way came to
be known as "wild rubber." Moreover, transporting the crude
product through the jungles was hard and expensive and the rubber
obtained under these conditions was not always so clean or high in
quality as might be wished.

"If rubber trees grow from the seeds which nature scatters in the
jungle," said Wickham to himself, "why should they not grow from
seeds put into the ground by hand?"

"If rubber trees could be raised from seed, they could be planted
in the open in rows where they could easily be tended and tapped,
and the rubber gathered quickly and safely. Instead of having to
brave the dangerous jungles, men could plant and cultivate rubber
in spots of their own choosing so long as they chose places where
the climate was right."

For many years people only laughed at Wickham's great idea, but
like Goodyear he had faith enough to persevere. While in Brazil he
planted some rubber seeds to see what would happen. The seeds DID
grow, and the book which Wickham wrote about his idea and his
