A Corner in the Snake Park at Butantan (Sao Paulo) 



(Snakes from al! parts of the country are sent to Butantan ; every month their poison is 



extracted for the preparation of a serum which has been proved to be 



an excellent remedy in case of poisoning by snakes) 



Mill for grinding Indian Corn 



(The corn is placed in a hole in the tree trunk, into which the cone at the end of the beam 



fits. Through the filling and emptying of the water-trough at the other end the 



beam rises and falls and thus the cone crushes the corn.
