THE INCAS AND OTHER RULERS OF PERU. 27 



The illustration of " painted hills " here offered represents 

 what may be seen in many parts of Peru, and especially along 

 the slopes which border the southern deserts, notably Tarapaca 

 and the adjoining provinces, and on the rocky walls of the few 

 rivers which traverse those sandy wastes where the rainless 

 climate permits the preservation for ages of these curious relics 

 of bygone inhabitants. 



I must here state that my thanks are due to Mr. Ed. Manly, 

 M.I.C.E., formerly Engineer-in-Chief of the Nitrate Railways 

 Co., and Mr. Herbert J. Griffin, the present managing director 

 of that undertaking, for their kind and important assistance in 

 the preparation of this paper.
