Because of the immense value of the rubber product, gold attracts less
attention than it would in some other country. The rubber industry
is extensive and thousands of the wild rubber trees are located and
tapped. The trees usually are found near streams and the search for
them leads the rubber-hunter farther and farther into the unbroken
wilderness. Expeditions from time to time are sent out by rich
owners of rubber "estates" to explore for fresh trees, and after
his sojourn at Remate de Males and Floresta, so full of interest,
Mr. Lange accompanied one of these parties into the unknown, with
the extraordinary results described so simply yet dramatically in
the following pages, which I commend most cordially, both to the
experienced explorer and to the stay-by-the-fire, as an unusual and
exciting story of adventure.

PREFACE

It is difficult, if not impossible, to find a more hospitable and
generous nation than the Brazilian. The recollection of my trip through
the wilds of Amazonas lingers in all its details, and although my
experiences were not always of a pleasant character, yet the good
treatment and warm reception accorded me make me feel the deepest
sense of gratitude to the Brazilians, whose generosity will always
abide in my memory.

There is in the Brazilian language a word that better than any
other describes the feeling with which one remembers a sojourn
in Brazil. This word, _saudades_, is charged with an abundance of
sentiment, and, though a literal translation of it is difficult to
arrive at, its meaning approaches "sweet memories of bygone days."

Although a limitation of space forbids my expressing in full my
obligation to all those who treated me kindly, I must not omit to state
my special indebtedness to three persons, without whose invaluable
assistance and co-operation I would not have been able to complete
this book.

First of all, my thanks are due to the worthy Colonel Rosendo da Silva,
owner of the rubber estate Floresta on the Itecoahy River. Through
his generosity and his interest, I was enabled to study the work and
the life conditions of the rubber workers, the employees on his estate.

The equally generous but slightly less civilised Benjamin, high
potentate of the tribe of Mangeroma cannibals, is the second to whom I
wish to express my extreme gratitude, although my obligations to him
are of a slightly dif
