Book Description
Excerpt from A Pathological Survey of the Para Rubber Tree (Hevea Brasiliensis) In the Amazon Valley In the Tropics, where plant pathology is in its beginning, it seems desirable to record all fungi on a given host, for the reason that under the conditions of clearing away the native forest, fungi which now seem unimportant may later cause disease on the introduced crop. This has been largely true in the case of Hevea. Aside from the more practical consideration given to each fungus, some details with regard to the chief characteristics of the different species and the classes, orders, families, and genera to which they belong are pre sented. It is hoped that this will give the bulletin a wider useful ness from a taxonomic standpoint and will also explain many of the terms necessarily used in a work of this kind.

Book Description
Excerpt from The Rubber Country of the Amazon I think it was in 1870 that I started to outfit my first expedition to the Amazon. It was not in any sense scientific nor had I the interests of the rubber trade then at heart. It was to be a hunting and fishing trip solely, varied by occasional battles with Indians. A treacherous companion, to whom I incautiously confided some of the outfitting details, betrayed the trust to my mother. She confiscated my gun, an elder sister hid the ammunition, so I was compelled to abandon the attempt for a short time, (forty years in retrospect is not long). And what a satisfaction to feel that one's early ambitions are finally realized, at least in part. The delay in the journey altered my viewpoint somewhat, and changed the equipment. The gun, hunting knife, and lasso did not seem so important as a Letter of Credit; nor did I have that intense yearning for slaughter that dominated Expedition No. I. Then, too, much rubber research in other tropical countries made the prospect of this trip particularly alluring. From the time when La Condamine made his report to the Royal Geographical Society at Paris upon the curious gum that he found in the Brazils, the Amazon river has been visited by a procession of specialists. Some went for adventure, some for trade and some in the interest of science. To such as Humboldt, Agassiz, and Spruce whose search was for knowledge the reward was the richest of all. With one-half of the worlds product of india rubber coming from the mighty Amazon, with the great northern states of Brazil, and notable portions of Peru and Bolivia dependant wholly upon the rubber business it seemed time that the story of "Ouro Preto" (black gold as the Brazilians most appropriately call india rubber), be fully and fairly told. Personally I am more than pleased that it is my fortune thus to tell the story. Not altogether my own experiences but a composite sketch, to which Governors of states, Captains of trading vessels, half breed rubber gatherers, American, English, German and Brazilian business men have all contributed.

Book Description
Excerpt from Palm Trees of the Amazon and Their Uses In this little work careful engravings from my original drawings are given, with a general description of each species, and a history from personal observation of the various uses to which it is applied, and of any other interesting particulars connected with it. Several of the species here figured are new, and among them is the Palm which produces the piassaba, the coarse fibrous material of which brooms for street-sweeping are now generally made.

Book Description
Famous explorer and author, Joseph Fourde Woodroffe spent his life conquering the unknown and sharing his knowledge with other historians and explorers via his books. One of two books Woodroffe wrote on the Amazon, "The Rubber Industry of the Amazon" is an in-depth exploration of the culture, commerce, and capitalization of the resources and people along the mighty Amazon river. The second longest river in the world at 4,345 miles, the Amazon has long been a paragon of mystery, housing some of the world's most valuable resources and the most reclusive native people. An international rubber 'boom' in the 1800s exposed this region to the undue influence of European and Asian investors, culture, and disease, resulting in major changes within the region. Woodroffe makes an effort to expose the horrendous treatment of the native people, emphasizing the incredible toll of outside influence and the unjust monopolization of both resources and profits for outside gain, much of which he attributes to the folly of the Monroe Doctrine. This doctrine, established for former president, James Monroe, is an attempt to prohibit European colonization and instead view new forays into colonization as acts of international aggression. Woodroffe is of the opinion that the United States has no business in South America and that by refusing to allow colonization, the U.S. is actually harming the native people of the Amazon. While Woodroffe's position may not be popular among today's historians, there is no arguing with the compelling and detailed logic delineated in "The Rubber Industry of the Amazon." This book tells a fascinating story of civilization and industrialization, and clearly articulates a staunchly conservative view of capitalism. It would be an excellent read for anyone interested in World politics, commerce, the history of the Amazon basin, early exploration of the Amazon, or a general interest reader, hoping to glean new insight into the world of the mysterious and ancient Amazon rain forest.

Book Description
Excerpt from The Ceara Rubber Tree in Hawaii The latex, or milky sap, of the rubber tree is of very complex composition, containing starch, sugars, gums, resins, proteids, and salts, as well as rubber. The milk tubes are not continuous - that is, it is not possible by cutting through the network of tubes at the base of the tree to drain out all of the latex. The latex-bearing tissues may rather be compared to a series of short tubes joined end to end with permeable diaphragms between. In the living plant there is free transfer of latex from one tube to another, but there is no circulation comparable with the circulation of the blood in ani mals. There is no rise and fall of the sap, as is the common belief, and so far as has been determined, there is no ruling direction of movement at any time of the day or period during the growth of the plant. The circulation of the sap in the tree or of latex in the milk tubes is simply a process of life, a phenomenon of growth. The rubber in the latex in the milk tubes is supposed to exist as an emulsion, somewhat comparable to fat globules in milk. When a milk tube is ruptured, to permit its contents to escape, the rubber globules rapidly agglutinate, the function of rubber apparently being to close up wounds and prevent the loss of water from the tree by evaporation. The flow of latex when the milk tube is ruptured is not due to the continuity of the tubes, as would be supposed, but is because the latex is under tension in the growing trees. When the pressure is relieved by the breaking or cutting through of the tissues containing the latex, the tension being released, the milk tubes for a short radius around the wounds quickly empty themselves of their contents.

Book Description
The first complete account of the rise and fall of the rubber economy in Brazil provides a dramatic example of one of the boom and bust cycles traditionally associated with Brazilian economic history. The Amazon rubber trade was one of the most important export booms in the history of Latin America, dominating the economic life of the Amazon for 70 years until the successful cultivation of rubber trees by the British in Southeast Asia. Yet this long period of vigorous economic activity left the basic structure of Amazonian society relatively unchanged. One of the author's main concerns is to explore why rubber exports did not generate substantial growth in either the industrial or the agricultural sector, and she finds the answers primarily in the relations of production and exchange that characterized the Amazon's extractive economy. The study also considers the impact of political decentralization and regionalism on the Amazonian economy, draws comparisons with the coffee boom in Sao Paulo that induced sustained industrial growth in that area, and traces the consequences of the rubber economy's collapse on the social, political, and economic life in the Amazon.
