Fig. 108. — A tislimg party near Yuriniaf;uas. Roots of a poisoiKjiis plant locally 

 known as " barbasco " are mashed in water in the bottom of a canoe. The water 

 is thrown into a small stream, resulting in the stupefying of large numbers of 

 fish. These are then readily caught with net or spear. 



Fig. 109. — The final process of making herbarium specimens. When the 

 plants are brought in, portions are laid between sheets of blotting paper and 

 corrugated cardboard, cinched together, and slung over oil burners. The heat 

 passing through the cardboards dries the specimens in a short time.
