AREQJJIPA. 



On the following morning, I boarded the train for Arequipa. 

 We ascended from sea level to a height of 7550 feet, the 

 railroad winding about the mountains in a most bewildering 

 way, constantly ascending. At the outset, were undulating 

 hills covered with flower-bearing plants, then tracts covered 

 in places with cacti, followed by a long tract nearly flat, 

 barren and sandy. Toward the end of the journey, the ground 

 became rough and broken on our right, while on the left was 

 a refreshing green valley opening out before Arequipa. We 

 stopped at many small stations on the way. It was only 

 at these that trees or shrubs were seen, and about these, figs, 

 strawberries and pears are occasionally grown. 



My first day in Arequipa was spent in preparing for jour- 

 neys to come. The remaining days here were devoted to 

 tramping about the adjoining valley in search of butterflies 

 which were extremely scarce. All the land that nourishes 

 vegetation is irrigated, and it was only in this irrigated valley 

 that any collecting was possible. Five species of butterflies, 

 two of them the same as those taken at Mollendo, were all 

 that were taken. (Pieris Blanchardii Butl., P. Microdice 

 Blanch., Pamphila Begga Prittw., Butleria Cypselus Feld., 

 and one unidentified Hesperid.) 



Arequipa lies at the base of several high mountains, the 

 highest being Vol Misti, snow covered at points. The houses 

 are built of a soft volcanic stone, the poorer ones of mud. 

 The inner court is nearly always present. The majority are 

 inhabited by Indians and poorer natives, and are far from at- 

 tractive. The streets are paved, most of them having a 

 narrow channel of running water on the side. The stores were 

 fair, considering the locality, offering native products at very 

 low prices, but charging exorbitantly for any imported goods. 

 The days were very warm, but the nights, owing to the 

 proximity of the mountains, were quite cold. 



Two trains each week leave Arequipa for Puno, one of 

 them connecting with the weekly steamer across Lake Titicaca, 

 which lands one some forty-eight miles from La Paz, the cap- 

 ital of Bolivia.
