plain. Where streams retained water, the Indian horses were 

 located, and about these districts were some signs of culti- 

 vation, barley and potatoes being the main product. In the 

 distance on all sides, rose snow capped mountains. We cov- 

 covered but fifteen miles this first day, spending the night 

 at an isolated " tambo," called Ventilla. On the following 

 day, we reached Calamarca, twenty-two miles beyond. This 

 is a fair settlement, occupied, as are all the villages here, 

 solely by Indians, with the consequent inactivity and lack of 

 energetic movement. We lunched the next day at Ayoaya, 

 a plate of soup and three eggs, divided with the Indian. W"e 

 intended to reach Chicta, the next lonely tambo, by sunset, 

 but were in error as to distance and travelled the last two 

 hours by moonlight. The sinking of the sun, the dreari- 

 ness of the surroundings and the cold, oppressed me greatly, 

 and thoughts of home and its comforts filled my eyes to over- 

 flowing. The distance covered today was 30 miles, a suffi- 

 ciency for one day, considering the flat monotony of the trail. 



Sicasica, twelve miles beyond, was our next stopping place. 

 We hired post mules here to carry our loads, in order to 

 save our animals a bit, and as a result we made better time, 

 passing first Aroma, an isolated tambo, and then Pandura, 

 twenty-seven miles from Sicasica. Caracollo was the next 

 place we reached, and we rested there for a day. We had 

 travelled southeast to this settlement, but now our road, the 

 only one, led due east. Leaving early, we reached the hilly 

 country, our past route being over the level monotonous 

 pampa. At sunset, we reached a small Indian settlement 

 called Im, and passed the night there, having covered thirty- 

 six miles since morning. Tambos, or post stations, are situ- 

 ated at irregular intervals, and are usually one story build- 

 ings, surrounding a large yard. They are obliged by law 

 to grant travellers lodgings and food, also to let mules if 

 they are desired. They charge twenty cents per league, and 

 ten cents per league to the Indian who goes to bring the 

 mules back. 



The rooms of the tambos are bare of furniture, a raised 

 platform of hardened mud answering for a bed.
