nous population of Colombia. This is a country highly 
developed spiritually, intellectually and materially. The 
use of these plants in the native cultures of a country 
with such a modern civilization represents, paradoxicallly, 
a condition far in advance of that usually found where 
native cultures frequently weaken or disappear. It dem- 
onstrates for the indigenous civilizations of Colombia a 
spiritual power and a cultural balance as well as the ex- 
istence in the mind of the native of a fixed purpose in 
his use of narcotics. It is likewise significant and of a 
value beyond measure for science that we can look in 
this present age to such a rich knowledge of economic 
plants by primitive peoples. Here we have at hand the 
possibility of studying materials 7m situ. For botany, for 
anthropology and for medicine, Colombia is a seemingly 
inexhaustible treasure-house.
