cartographers, who have drawn them to make the map look pretty. They do not exist. I have left them in order to draw the attention of the reader to them. The position of the Arinos-Juruena is from 1 to 1? degrees farther west than it is there drawn, and should be where I have marked the red line of my route.
(f) Everything that was of interest pictorially, geologically, botanically, or anthropologically was photographed or sketched. Astronomical observations were constantly taken to determine the positions of our camps and places of importance.
Botanical and geological collections were made, but unfortunately had to be abandoned.
(g) During the journey the head waters of the following important rivers were visited: The Rio Vermelho, Rio Claro, Rio Araguaya, Rio Barreiros, Rio das Mortes, Rio S. Louren?o, the Cuyaba river, the Xingu, the Paranatinga, the Paraguay river (Paran��), the Rio Arinos, the Secundury.
(h) The entire course of the river Tapajoz was studied, and also the entire course of the Amazon from its mouth almost to its birthplace in the Andes.
(i) Useful vocabularies were drawn up of the following Indian languages: Bororo, Apiacar, Mundurucu, Campas or Antis.
(k) The expedition has furthermore shown that it is possible with poor material in the way of followers to accomplish work of unusual difficulty.
(l) That it is possible for people in a normal condition of health to go at least sixteen days without food while doing hard work.
(m) That it is possible to cross an entire continent--for one entire year--in the company of dangerous and lazy criminals without any weapon for protection--not even a penknife--and to bring forth from such poor material remarkable qualities of endurance, courage, and almost superhuman energy.
(n) Last, but not least, on that expedition I was able to collect further evidence that a theory I had long held as to the present shape of the earth was correct. I had never believed in the well-known theory that a continent, now submerged, once existed between America, Europe and Africa--in other words, where the Atlantic Ocean is now. That theory has found many followers. In support of it one is told that such islands as Madeira, the Canaries, the Azores, are the topmost peaks of a now partly submerged range of mountains which once stood upon that vanished continent. It is also a common belief that Northern Africa underwent the contrary process, and was pushed up from under the sea. That is why--it is said--the Sahara Desert, which was formerly, without doubt, an ocean bed, is now dry and above water.
One has only to look at any map of the entire world to see what really happened to the earth in days long gone by. Let me first of all tell you that there never existed a continent between Africa and South America. In fact, I doubt whether there is as much as a square mile between those two continents more submerged to-day than it was thousands upon thousands of years ago.
Here is what really happened. The earth at one period changed its shape--when, is merely guesswork, and is of no consequence here--and the crust of the earth--not the core, mind you--split into two great gaps from Pole to Pole, with a number of other minor fissures. In other words, the earth opened just like the skin of an over-heated baked apple. The African and American continents, as well as Australasia, with New Guinea, the Celebes Islands, the Philippine Archipelago and China, which before that event formed part of one immense continent, thus became divided, leaving North and South America isolated, between the two great Oceans--the Atlantic and the Pacific--which were then, and only then, formed.
It is easy, by looking intelligently at a map, to reconstruct the former shape of the world. You will notice that the most western portion of Africa fits exactly into the gap between North and South America, while the entire African coast between Dahomey and the Cape Colony fits in perfectly in all its indentations and projections into the coast line of South America. The shores of Western Europe in those days were joined to North America, and find to-day their almost parallel and well-fitting coast line on the east coast of the United States and Canada. On the opposite side of the world, the western side of South America, the same conditions can be noticed, although the division of the two continents (America and Asia) is there much wider. Fragments were formed, leaving innumerable islands scattered in the Pacific Ocean, half-way between the actual continents of Asia, Australia and America. A mere glance is sufficient to see how well Australia fits in along the Chilian and Peruvian coast, the great island of New Guinea along part of Peru and Ecuador, and the west coast of the Central American Isthmus. The Philippine Islands lay probably
