Steel is not made from that they call Steel Oar, hut 
Iron, fuch as is made from the rest. 
All the Oars that were feni you lie in one Bed or Seam, 
but the hard Oars lie ufually nest the Rocks on each fide y 
and the foft Oar in the midfl. 
The Rocks between which they lie are a grey Lime- 
stone. 
There is no rock underneath (as you feem to conceive*) 
for the Oar lies between Rocks on each fide, or rather in 
the Clefts of Rocks which they follow, ft ill digging deeper 
many Fathoms. Sometimes the faid Clefts ( which are 
filled with Oar) are an Inch, fometimes a Foot broad % 
fome times three or fout^Tards,but ft ill one continued Vein 
running downwards towards the Center of the Earth.

better, than that which is brought from the Eaft Indies. 
Witnefithe Tea-Pots now to be fold at the Potters in the 
Poukrey in Cheap fide, which not only for Art, but for 
beautiful Colour, too, are far beyond any we have from 
China. Thefe are made of the Engliffi Hematites Staf- 
fordshire, as I take it, by two Dutch-men, incomparable 
Artists.
