In the first treatise, we have joined the fact that the whole magical medicine of the Indians is based on certain religious ideas: the plants are inspired by ghosts to whom they owe their supernatural properties. These ideas can be further carried out and illuminated by examining the intoxicating and narcotic drinks of the Indians and the ideas associated with these drinks in greater detail. It is a well-known fact that the drunkenness is one of the Indian vices and that drinking action in the social life of most tribes play an excellent role.Every more important event in the life of the Indian, marriage, birth of a child, funeral, hunting and war trains, and above all purely religious festivals must be celebrated with excessive drinking of any fermented beer so that everything is going well. Such facts make it self-evident that certain religious ideas are associated with fermented drinks and drinking lags, and a more detailed investigation of the customs and traditions of the Indians confirms this assumption. Since this side of the Indian religion and magic has never been made an object of closer studies, I am only using my own research. These refer to the most important tribes of the Argentine and Bolivian Gran Chaco, partly to the wild or semi-civilized Indians of Ecuador.
