part 1] THE ANDES OF PEUIT AND BOLIVIA. Gl 



The Author found it difficult to account for the pre-Inca civilization 

 of the High Andes, except on the assumption of a recent elevation ; 

 a corresponding depression of about 1500 feet would render the 

 country round Tiahuanacu capable of cultivation. He referred 

 once more to the pre-Spanish burial-tumuli, just above high-water 

 mark near Arica, as precluding the possibility of any elevation of 

 the coastal region since historic times. This, in his opinion, did 

 not necessarily apply to the high plateau. 



In conclusion, he expressed his gratitude to the late Mr. W. E. 

 Balston, who enabled him to visit South America, and shared in 

 Prof. Sollas's regret that Mr. Balston had not lived to see the 

 result of the expedition which bore his name.
