On the next day, we covered thirty miles to a settle- 

 ment called Challa. Two hours after leaving Challa, we 

 crossed the ridge which we had been crossing for two 

 days. We went down, down into the valley, vegetation 

 gradually increasing. At night, we reached Tapacari, where 

 we remained through the following day. As it happened, 

 a religious festival was in progress and the settlement was 

 full of Indian "bands." A number of small images were 

 carried about. The man and woman of the tambo had 

 much trouble in placing their image in its case. The 

 image represented a knight, sword in hand, mounted on a 

 silver horse, with an attendant in some fancy dress stand- 

 ing at its side. One of the horse's legs being broken, it was 

 steadied with a stone. To whom all this homage is directed, 

 1 was unable to find out, although I heard it was in behalf 

 of El Senor Santiago, whoever he may be. That night, 

 one of the mules at the tambo became sick, and they all 

 considered it a punishment because they had broken the leg 

 of the horse. 



Parotani was reached on the evening of July 26th, after 

 travelling eighteen miles through the valley, whose sides 

 were steep and only thinly covered with vegetation. On 

 the 2 yth, we reached Cochabamba, having travelled two 

 hundred and fifty miles from La Paz. 



NORTH FROM COCHABAMBA. 



We spent two days here buying provisions and hiring 

 fleteros for our trip to the north. Leaving on the morning 

 of July 30th, we travelled two days over an undulating 

 country with scarcely any vegetation, camping at spots which 

 offered grass tor our animals. We soon reached Choro, a 

 scattering of huts near Cocapata, which was our objective 

 point. During the day, we saw many wild vicunas. Choro, 

 like Cocapata, is in a high region, trees and shrubs grow- 

 ing only in the valleys. The rest of the country is covered 

 with grass, interspersed with high rocky ridges, some of 

 them covered with snow.
