A deposit of contorted vo})y lava on the same coast about 

 one mile tarther noith. 



Hot springs on the south-east side of Port Ilesolution, 

 temperature about 100°. 



Hot springs on the west side of Port Resolution, 

 temperature about 200°. 



Stratified beds of a sort of argillaceous sandstone, closely 

 allied to ])umice stone, and used by sailors for holystoning the 

 <lecks, alternated with this, bands of cinders or slag. Tlieseai*e 

 seen in the cliffs on each side of the entrance to the harbour, 

 Avhere the sea has ex|)Osed a vertical section to view. 



Hot beds of white clay occur fuither to the west. These 

 are soft, when opened with a stick emit jets of sulphurous 

 steam, and have a temperature ranging up to 200° Fah. 



A small lake exists to the southward of this, the water of 

 which has a temperature of about 100° Fah. 



Beds of sulphur lie close to the active cone, as well as a 

 large deposit of lava which stands piled up to a height of 

 about 200 feet, the precipitous fice of which indicates that 

 it has issued forth in a very viscous state. 



Just at the foot of the mount and beyond it, there lies a 

 beautiful fresh water lake about one-and-a-half miles long by 

 half-a-mile in width. It is fed by one of the largest streams 

 in the island, it has no outlet to the sea, but disposes of its 

 superfluous waters by pouring them continuously into large 

 crevices on that edge whicli is next to the volcanic cone. 



The cone itself is composed of loose scorire lying at an 

 angle of about 2 to 1, with hardened lava protruding here 

 and there, and blocks of a more porous nature strewn upon 

 its surface. 



The top of the cone is occupied by two distinct craters of 

 about equal size and form, one, the farthest west being active, 

 the other extinct. The active cratei' is an oval basin about 

 700 feet long, 500 feet wide, and loO feet deep. Two la'ge 

 and one smaller vents occupy the bottom, the larger ones 

 being about .50 feet in diameter ; from these and from cracks 

 in the sides ot the ciater, jets of steam continually rise, and 

 the ground everywhere is almost too hot to toucli. Between 

 the eruptions, the crater is empty of lava, and there is 

 nothing but the hissing steam jets to indicate the existence 

 of the tremendous forces imprisoned below. 



Plate 7 gives a general view of the volcano from the 

 north-east, the entrance to Port Resolution being shown 

 on the extreme left.
