viscous mud were thrown over the rim. In 1895 the general shape 

 of the cone had not changed in any way, but on its top there was a 

 crater of about five feet in diameter filled with a very viscous mud 

 •which slowly flowed off through a break on the eastern rim of the 

 crater. The temperature of the mud was 82 F. 



2(b) To the west of No. 3 (a), rises a blunt cone No. 3 (b), which 

 has not been active since 1888 ; its sides are much denuded by rain 

 water, which has eroded deep furrows in it. On its west side, close 

 to the base is a small vent, hardly a few inches in diameter, which is 

 filled with liquid mud. 



3(c) On the southern side of 3 (a), close to the base, is a parasitic 

 cone of about 6 feet in height with very steep slopes. In 1888 and 

 1889 there was a small crater at the top filled with muddy water, 

 which was slowly flowing off. In 1895 it had entirely ceased to act. 

 From the above description it will be seen that the general shape 

 of No. 3 cone had not altered. It is, however, quite certain that the 

 vent of No. 3 (a) has undergone several changes, that it was com- 

 paratively active in 1888; in 1S89 the activity had decreased, while 

 in 1895 it begun with renewed vigour. Vent 3 {b) showed no signs 

 of a change, while No. 3 (c) had become entirely extinct. The tem- 

 perature also exhibits some changes ; in 18S8 it was between 69° and 

 77 while in 1895 it was at the same vent 82 F. 



No. 4, — A high cone rising about 40 feet, north of No. 3 (a). Like 

 the former, it consists of a gently inclined base on which rises 

 rather suddenly a cone with very steep sides. In 1888 it hardly 

 exhibited any signs of activity ; there was a small vent on the top, 

 out of which flowed a narrow stream of mud with a temperature of 

 75 F. In 1889 it had resumed its activity ; on the top was a crater of 

 about a foot and a half in diameter filled with a very viscous mud, which 

 rose to the rim of the crater, gas bubbles were frequent and large, 

 and after a very heavy outburst the mud ran over the rim. In 1895 

 the cone had again relapsed into inactivity, but at its northern base 

 where it seemed to have been traversed by some deep fissures very
