LETTER 11. 59 



thofe Woods. Black-Rock Pond is about a quar- 

 ter of a mile diftant Northwards from Charles 

 Town ; the Water whereof is milk warm, occa- 

 iioned no doubt, by a mixture of thefe hot with 

 cold Springs, and yet it yields excellent Fiflies 

 in their kind, ^viz, Silver-Fiflies, Slimguts, and 

 the beft Eeles in the world perhaps : Silver-Fifli 

 has a bright deep body of about eight inches long, 

 which taftes like an EngliOi Whiting: Slimgut 

 has a large Head, in too great a fize to its Body, 

 which may be from ten to two-and- twenty inches 

 long ; it eats like our Gudgeons, and is not un- 

 like them in colour : Their Eeles have no rank 

 tafte at all, which makes them fo much admired. 

 For a farther account of this Pond, fee paragraph 

 9, 10, II, and 12, of my firft Letter. 



38. We are diflurbed not a little by frequent 

 Earthquakes, which we look upon to be caufed 

 by thefe Veins of Sulphur, Brimftone, (^c, that 

 being over-heated, either blow up on a fudden like 

 a Granade or Bomb-Shell, at lead fhake the ground 

 till it gets vent out into the open Air, or elfe burn 

 gradually away, leaving the ground about them 

 fo hollow till it at laft drops in : The former of 

 which cafes was (in my opinion) the fate of the 

 great Mountain at St. ChriJIophers, when the pro- 

 digious Cavity was made ; for it feems to have 

 undergone fome fuch terrible Convulfion. Earth- 

 quakes are obferved there to be moil frequent in
