MINBU. 37 



In 1889 the general shape had not altered; there were still 

 eicht vents visible, of which, however, one on the top of a low parasitic 

 cone, had ceased to be active, while a second one ejected gas only, 

 which came out with hissing noise without being accompanied by 

 mud. The northern vent was the most active; it formed a crater- 

 like basin filled with muddy water, which seemed to be in a state of 

 boilincr caused by the incessant rise of gas bubbles. Five feet to the 

 west of this was another, and 15 feet south of the first a third 

 vent. These three vents were all situated inside a low crater filled 

 with mud in a more or less liquid state. Of the smaller ones, a low 

 cone, which was very active in the previous year, had ceased to be 

 active, the others were small holes filled with watery mud in which 

 gas bubbles rose. 



In March 1895 there were, besides a number of smaller, seven chief 

 vents, one of which, the low cone already mentioned, was not active. 

 The others were all more or less active, and produced in one case a 

 considerable stream of mud. Beginning in the south, vent (a) is 

 represented merely by an opening out of which flows a stream of 

 very liquid mud. The opening itself is marked by the incessant rise 

 of gas bubbles ; the temperature of the mud was 84 F. 



Next to this, about 10 feet west, were a series of small holes, 

 filled with very liquid mud, one of which was very active, incessantly 

 throwing up gas bubbles ; the temperature of the mud was 79 F., 

 whilst in another case it was 78 F. 



(c) About 30 feet north of (a) there were a series of small vents 

 arranged in a line running in easterly direction towards (g), the 

 extinguished cone. None of these vents were very active. A small 

 stream of very viscous mud was flowing out from the largest vent (c) ; 

 gas bubbles were rare. 



{d) About 7 feet north of (c) there was a hole which was exceed- 

 ingly active. A large stream of watery mud flowed out of it, and the 

 position of the hole was marked by the permanent rise of large gas 

 bubbles, which sometimes threw the mud some distance up, but 

 without forming a crater or cone. The temperature was 85 F.
