but almoft all Pentagonal, or Hexagonal,- only we ob» 
ferved that a few had feven fides ; and many more Pen- 
tagons than Hexagons ; but they were all irregular, for 
none that we could obferve had their fides of equal 
breadth; the Pillars are fome of them ij, fbmeiS 
Inches, fome two Foot in Diameter, none of them are 
one entire Stone, but every Pillar confifts of feveral 
Joynts or Pieces, as we may call them, of which fome 
are fix, fome twelve, fome eighteen Inches, fome two 
Foot deep. 
Thefe Pieces ftand dole one upon the other, not joyn- 
ing with flat furfaces ; for when you force one off the 
other, one of them is always Concave in the middle, 
the other Convex. There are many of this kind of 
Joynts, which lye loofe upon fome part of the Caufway, 
and on the Strand, which were blown or wafli'd ofiF the 
Pillars : Thefe Joynts are not always placed alike, for 
in fome Pillars the Convexity is always upwards, and 
in others it {lands always downwards. They always 
1 1 lye as clofe as 'tis pofTible for one Stone to lye upon 
anoiher, fb that on the out-fide of the Pillars you can 
but difcern the crack chat joyns the two Stones : When 
' you force them aiunder, both the Concave and Convex 
Superficies are very fmooth, as are alfo the fides of the 
Pillars which touch one another : For when we pulled 
away fome of the Pillars which ftood outwards to the 
Weather, the fides of the Pillars which ftood next be- 
hind them looked as freih as Scones newly hewen, be- 
; ing of a whitiih Free-ftons colour, but a fioer clofer 
gret ; whereas when we broke fome pieces off them , 
the infide appeared l^ke dark Marble. 
' The Pillars that are made up of thele Joynts ftand fo 
clofe one to another, that a Knife can hardly be thruft 
in between the fides of: them \ and though fome have 
five fides, and others of them fix, yet t!ie Contextures 
of them are (b adapted, that there is no vacuity be- 
tween
