%8 GEOLOGICAL STRUCTURE. 



does not appear to be very rapidly worn away. 

 Large masses of travertine hung from the rocks on 

 the sides of the brook, embedding sticks and other 

 things, but I never saw any organic remains in the 

 fundamental rock. I believe the pool, which is 

 called Ranoo Klakka, to be an old crater ; and 

 about half a mile S.E. of it is another similar cir- 

 cular pool, called Ranoo Pakis. The two occupy 

 the extremities of a low ridge, from which the 

 ground slopes gently in every direction, and it ap- 

 peared to me that the beds had a qua- quavers al 

 dip from each of the pools. Certainly, on the S.W. 

 side of Ranoo Klakka the beds dipped from it to 

 the S.W. and seemed to curve round it ; and at 

 one or two detached points on other sides, I observed 

 a slight dip from the pool. I made the height of 

 the passangerang of Klakka, by the mean of four 

 observations, to be 811 feet above the sea. Ranoo 

 Klakka was said to be 65 fathoms or 390 feet deep. 

 The temperature of its water, at a depth of three 

 feet, was 88°, although the air in the shade never 

 rose above 87° in the hottest part of the day, and at 

 nine o'clock at night was at 79°. 



On a little eminence, overlooking Ranoo Pakis, 

 about half a mile from the guest-house, was a small 

 wooden pandopo, that seemed to have been erected 

 solely for the purpose of enjoying the view, which was 

 certainly a most lovely one. About sixty feet below 

 was the still water of the lake, environed by a steep 

 bank covered with dense bush and jungle. From the
