Pave, becaufe it feera’d impoitible to reduce them to their 
feveral proper Species . However, clofe by the Pit we 
found a valuable Curiofity, viz,, a Stone for fubftance 
like thofe they make Lime of 5 of a comprefs’d Cylinder 
Form } and as it were cut off even at each End : About 
8 Inches long, and 3 in breadth: Its Superficies adorn’d 
with equidiftant Dimples, like Dr. Plot's Lepidotes^ Hifi. 
Ox. chap. 5. par. 55* and in each Dimple a fmall Circle; 
and in the Center of each Circle a little Stud like a Pins 
head. This is the only Curiofity of the kind I have 
feen } and is not referable to any thing I can think of, 
either in the Animal or Vegetable Kingdom. Among 
the Iron Oars of the fame Hills we found fome new 
Spars, and feveral Specimens of Oars (hot into a conlrani: 
and regular Figure, tho’ not reducible to any Animal 
or Vegetable Bodies. 
About 5 Miles thence, at a place called Pont y PvpI 
in this County (where, as alfo at Lhan Elhi, there are 
Furnaces and Forges,) we found more Coal and Iron- 
Mines } and collected fome fair Reprefentations of the 
Leaves of Capillary Plants on the Iron Oar, but found 
no Branches. One Major Hanbury of this Pont y Pool , 
(hew’d us an excellent Invention of bis own, for dri- 
ving hot Iron (by the help of a Rolling Engin mov’d 
by Warer) into as thin Plares as Tin : But without a 
Draught of the Machine 1 cannot give you a Notion of 
it. They cut their common Iron Bars into Pieces of 
about two foot long} and heating them glowing hot, 
place them betwixt thefe Iron Rollers } not acrofi, but 
their Ends lying the fame way as the Ends of the Rol- 
lers. 1 he Rollers (moved with Water) drive out thefe 
Bars to fuch thin Plates, that their Breadth, which was 
about 4 Inches, becomes their Length, being extended 
to about 4 Foot} and vvhst was before the Length of 
the Bars is now the Breacth of the Plates. With thefe 
Plates he makes Furnaces, Pots, Kettles, ^Jauce-Pans, &e.
