226 Account of a visit to Fuppd ihung. [No. 3 ? 



render it certain that it mtist long have heen in a condition for vege- 

 tation to flourish upon it, but it is scarcely possible, even in the dry 

 climate of upper Burma, that a volcano of Miocene age should have 

 retained its form so perfectly. It is more probably Pliocene. Its 

 bulk is not great, and, from the absence of other vents in the neigh- 

 bourhood, so far as is known, it is scarcely probable, that its volcanic 

 activity can have extended over a lengthened geological period. I 

 could not leam that there was the slightest tradition among the 

 people as to its ever having been in action within the memory of 

 man, a circumstance, on the grounds mentioned, extremely improba- 

 ble. The occurrence, on the summit, of the common brakes, and 

 doubtless of other plants of temperate regions, renders it probable 

 that the close of the glacial period found its surface in a fit state to 

 support vegetation. 



The discovery of a volcano of comparatively recent geological date 

 in Burma is the more interesting from the circumstance that the 

 long line of volcanoes which has been traced throughout the Eastern 

 archipelago has hitherto appeared to end abruptly at Kyouk Phyfa 

 on the Arakan coast. The so-called mud volcanoes of Memboo have 

 no connexion with true volcanic action, but igneous eruptions have 

 been recorded at Kyouk Phyu and Cheduba.* Puppa is very little 

 removed from the continuation of a line passing through Barren 

 island and Ramri, and there is thus a possibility of the extension of 

 the great eastern line of volcanic outbursts into the countries of 

 Western China - y probably, as at Puppa, in the form of extinct cones. 



I left Puppa on the 30th October, and reached Pagan the next 

 day about mid-day, the road by which I returned being somewhat 

 shorter than that by which I went to the mountain. 



* There is a gi«eat peak standing out prominently from the west or Arakan 

 side of the Yoina, a little north of west from Ramri. I have no idea of what 

 its geological formation is> but it does not look like a volcano. Still it may have 

 Leeu one.
