HEIGHTS OF CENTRE AND BOUNDARY. Jl 



here and there to be seen on the broken edges of 

 the crater. Near the present orifice was another 

 circular space marked out at the bottom of the crater, 

 quite smooth, and strewed with small pebbles, which 

 was probably an older orifice lately filled up. 



A little detached from this cone another conical 

 mound of great regularity rose from the plain, the 

 surface of which was of a reddish colour, and was 

 scantily covered with young trees and small bushes, 

 but neither in this nor on any other part were any 

 lava streams visible. The Bromo is occasionally 

 much more active than when we saw it, exhibiting 

 a bright light, or appearance of flames, as it was 

 described to us, and throwing up hot stones, cinders, 

 and ashes. I observed the barometer at the edge 

 of the crater where we stood, which was its lowest 

 part, and also at the edge of the Sandy sea at the 

 foot of the precipice near the road to Wonosari. 

 and I found that the point of the crater was 516 

 feet, and the peak of the Ider-Ider 1378 feet above 

 that part of the Sandy sea. Some part of the 

 central mass, however, rose at least 300 feet above 

 the part of the crater where I observed. This 

 active vent was certainly on a small scale, and but 

 an insignificant exhibition of volcanic power. Still, 

 to lean over the crater and listen to the roar below, 

 and watch the power with which the blasts of steam 

 or smoke were blown into the air, afforded the 

 mind a present measure by which to estimate and 

 call up to the imagination the condition of things
