LETTER IL 39 



1 5. This Plain ended at the Verge of a vaft 

 and deep Cavity, which I fhall now delcribe in 

 the eafielt and beft method my parts and memory 

 will allow of. This Cavity feems by the eye 

 about a Mile in circumference, is exadly round, 

 and the infide as fteep as could be defcended into, 

 and that not without the help of the Shrubs and 

 Bufhes growing in it, and but in two places only. 

 I looked down into it with Horrour, obferving 

 large and continual Clouds of Steam to arife up 

 from the hot Veins of Sulphur, Brimflone, &c^ 

 with which the bottom of it every where abound- 

 ed. The infide of this prodigious Cavity ( for at 

 leaft half way downwards ) was folid rock over- 

 run with very fhort blackifli Mofs 5 and the Rim 

 at Top, except in that part of it which joyned to 

 and indeed made part of the plain, was not above 

 twenty, or perhaps in one or two places fcarce 

 ten yards wide. 



16. A furlong or better off on our left hand 

 towards the South Eaft upon this Rim, is a large 

 rocky Mount called Mount Mifery from a rafli 

 fool-hardy Perfon, who in attempting to get up 

 fo fteep a Precipice fell backwards, and met with 

 Phaeton's^ deftiny of courfe. It is the higheft 

 point of Land on St. Chrijhpher^^ and by the in- 

 habitants is computed to meafure from the Sea 

 fide a perpendicular mile and a half : however, 

 I cannot think it fo high by a full quarter of a 



c 4 mile.
