many cascades and mountain torrents glistening as silver. 

 Brush and some small trees began to appear, and, as we de- 

 scended, became thicker. Rain began again and continued 

 through the rest of the day. 



Shortly after 5 p. m., we reached a settlement called 

 Yanacachi, where we spent the night in the only house open 

 to travellers. 



We made an earlier start in the morning, the road leading 

 down the valley towards the river. Orange and banana trees 

 were found here, also coffee. At noon, we thought we 

 would be able to reach Chulumani before nightfall, and so 

 kept on after a light lunch. In some places, the road ex- 

 tended along a precipice hundreds of feet above the river. 

 Only in a few places is the side of the road protected. We 

 made the ascent of a mountain surpassing anything we had 

 yet attempted, but accomplished the climb and reached Chulu- 

 mani in the valley beyond without accident. Our mules, how- 

 ever, were badly used up. It was near here that I saw my 

 first Morpho (M. Achillaena Hubn.). There being no public 

 house here, we were quartered with new made friends. 



On the following morning, I collected on a road down 

 to the valley and up the other side. The weather being 

 unfavorable, results were not satisfactory. My later excursions 

 were made in different directions to the valley beneath. 



Chulumani consists of one and two story houses built of 

 adobe. There are two squares in the town, one used as a 

 market place. From La Paz, Indians bring on mules dried 

 sheep or " chalona," dried beef, potatoes, onions, etc., also 

 cheese in small cakes, which is very popular. On the re- 

 turn trip they take coca, sometimes bananas and oranges. 



The lower slopes of the valley are studded with terraced 

 patches of coca, with occasional planting of orange or 

 banana trees. 



It is impossible to follow the bottom of the valleys for any 

 great distance because in places the steep sides are covered 

 with impenetrable brush and the bottom narrows and permits 

 he streams to pass only through deep fissures in the rock.
