Few people realize that Brazil is larger than the United States of North America, Germany, Portugal, and a few other countries taken together. The interior is practically a terra incognita--although the ancient Jesuits and, at a later date, escaped slaves and native rubber collectors have perhaps found their way inland to a considerable distance.a selection from the PREFACE SOUTH America is, to my mind, "the Coming Continent"--the Continent of the future. Everybody knows the wealth of the Argentine, Peru, Chile, and Bolivia; but the interior of Brazil, the largest and richest country of all, not unlike forbidden Tibet, was perhaps better known a century or two ago than now.

When I started on the transcontinental journey I did not take Europeans with me. It is not easy to find men who can stand the strain of so long a journey. I was also not surprised, although I was disappointed, not to be able to obtain suitable officers in Brazil to go part of the journey with me, so that I might be relieved of a portion of the tedious scientific work of the expedition, especially taking and computing daily astronomical observations, to which much time has to be devoted. All the work of all kinds eventually fell upon my shoulders, and after departing I found myself filling the posts of surveyor, hydrographer, cartographer, geologist, meteorologist, anthropologist, botanist, doctor, veterinary surgeon, painter, photographer, boat-builder, guide, navigator, etc. The muleteers who accompanied me--only six, all counted--were of little help to me--perhaps the reverse. So that, considering all the adventures and misfortunes we had, I am sure the reader, after perusing this book, will wonder that we got back at all, and will be indulgent enough to give me a little credit for saving, through innumerable disasters--and perhaps not altogether by mere luck--all my note-books, all my scientific observations, as well as all the vocabularies I made of the various Indian languages of tribes found on my way. Also for bringing all my men out alive.
