Preface. xv 



Amazons, a subject which is destined to arrest the atten- 

 tion of enterprising men and nations. 



This edition has been prepared by adding to the narra- 

 tive of the expedition of 1867 a description of a more 

 southerly route, with such fresh observations as would 

 most likely interest the practical man. To swell the vol- 

 ume with scientific details would defeat the purpose of 

 the work, which is to present a popular yet accurate pict- 

 ure of the fairest and most promising part of our south- 

 ern continent. For elaboi-ate papers the naturalist is re- 

 ferred to the Proceedings of the Philadelphia, Boston, and 

 Salem societies. Some of the following chapters, abbre- 

 viated, have already appeared in the Scientific American, 

 Independent, Evening Post, Engineering and Mining 

 Journal, and Annals and Magazine of Natihral History. 



Special thanks for extraordinary favors are due to Sr. 

 Pinienta Bueno, of Para; to Mr. Meiggs, of Lima; to Wil- 

 liam R. Garrison, Esq., of New York ; to the Pacific Mail 

 Steamsliip Company; to Mr. Wettermann, of Chachapoyas; 

 and to Doctor Gait, Captain Rochelle, and other members 

 of the Peruvian Hydrographical Commission, under Admi- 

 ral Tucker. Tlie Map of the Maranon and several pages 

 derive their chief \alue, if not their existence, from the 

 generous contributions most courteously furnished by this 

 Commission.
