Farabee, Willian Curtis: The South Americar. Indian in his 
relation to Geographic Environment ». 
« Every geographical factor had its influence in this 
development. Sea and bay, lake ad river, mountain and 
vailey, forest and desert, temperature and humidity, wind 
and rain, sunshine and cloud, each and all had their effect 
in isolating or uniting, separating or deflecting, expanding 
or confining, the migrating peoples and in determining 
their physical developmert, their forms of culture, their eco- 
nomic and political organization. Man has followed no plan, 
has no standard. Whatever advancement he has made has 
been by chance rather than by choice, by accident rather

was decided to send an expedition for three years to the 
Amazon Valley for the purpose of making ethnological col-

layed and will probably not reach the field until the early 
months of 1913 ». 1. s. c., vol. IV, pp. 1 ss. 
« Ths Amazon River has challenged exploraticn since 
men who conquered Peru passed over the Andes and launch- 
ed their improvised craft on the waters that led them to 
the Atlantic. To the Spanish and Portuguese adventurers 
of the sixteenth century the greatest river system in the 
world was not unknown, yet to-day ists shores present for 
the most part an unbroken forest. 
Though names as Bates, Wallace, Mareoy, Coudreau 
and Agassiz are forever associated with the history of its 
exploration, especially on account of their contributions to 
to the natural history of the Amazon, the great wilderness 
has not been conquered. These men and others who, for 
the last four centuries, have followed its course from the 
Andes to the Atlantic and traced many thousand miles of
