THE PHILIPPINE ISLANDS. 55 



pies about two -thirds of the bottom. Its level 

 seems to be the same as that of the Lagiina. On 

 the southern edge of this pool are several hills of 

 sulphur, which are slowly burning. Towards the 

 south and east of it, a narrower crater is bemnninir 

 to form itself in the interior of the great crater. 

 The arch which it makes surrounds, like the 

 mora'me of a glazier, the burning hills by which it 

 is produced, and rests with both its ends on the 

 pool. The pool boils, from time to time, at the 

 foot of the burning hills. 



You can clearly distinguish, in the internal wall 

 of the crater, the situation of the difterently colour- 

 ed scoriae of which it consists. Smoke ascends from 

 some points of it. 



We observed from the place where we made a 

 drawing of the crater, a place on the opposite side 

 of it, where a fall into the interior seemed to afford 

 a slope, from which it might be possible to descend 

 to the bottom. It cost us much time and trouble 

 to gain this point, as we found the sharp and pointed 

 edge on which we walked, in many places impass- 

 able, and were frequently obliged to descend on the 

 outside almost to the bank. Being under the wind 

 of the fire, we were but slightly incommoded by 

 the sulphureous exhalations. 



The place just mentioned is that on which, 

 during the last eruptions, the water poured that 

 was thrown up. We attempted to descend into 

 several clefts, but were ultimately obliged to aban^
