dillera cle Yana-urcu, or the Llanganatis of the 

 Curaray, consisting chiefly of a wooded mountain 

 with many summits, called Rundu-uma-urcu or 

 Sacha-Llanganati. 



6. Jorobado or the Hunchback, south-south- 

 west half west from Yurac-Llanganati, and between 

 the river Topo and the head of the greater Rio 

 Verde. 



I have conversed with people who have visited 

 the Llanganati district as far as forty years back, 

 and all assure me they have never seen any active 

 volcano there ; yet this by no means proves that 

 Guzman invented the mouths vomiting flame which 

 appear on his map. The Abbe Velasco, writing in 

 I77O, 1 says of Tunguragua, " It is doubtful whether 

 this mountain be a volcano or not," and yet three 

 years afterwards it burst forth in one of the most 

 violent eruptions ever known. I gather from the 

 perusal of old documents that it continued to emit 

 smoke and flame occasionally until the year 1780. 

 Many people have assured me that smoke is still 

 seen sometimes to issue from the crater. I was 

 doubtful about the fact, until, having passed the 

 night of November 10, 1857, at the height of about 

 8000 feet on the northern slope of the mountain, I 

 distinctly saw at daybreak (from 5! to 6.1 A.M.) 

 smoke issuing from the eastern edge of the trun- 

 cated apex.- In ascending on the same side, aloiiL;

' The same morning 'Nov. u), at 4 A.M., I observed a great many 

 shooting-Stars in succession, all becoming visible at the same point 'about 40 

 from the zenith,;, proceeding along the arc of a great circle drawn through 

 Orion's Belt and Sinus, and disappearing behind the cone of Tunguragua.
