pure Clay, and then a Bed of foft, moift, black, (limy 
Earth ; and below this are Hills of a Kind of Earth 
without any Mixture of Grit or Sand. * Here are firft 
found Particles and Veins of Salt 5 and, descending a 
good Way through this and Some Salt Rocks, we 
enter into the firft Story, where there are a great 
many Alleys and Crofs-ways (which are run out to 
conftdcrable Diftances), and many large Caverns, out 
of which Salt has been cut. Here the Floor, Walls,

in that Way, hewed out of the Salt Rock, and well 
wrought in different Orders of Architecture. Some

the Mine, have a very beautiful EffeCt. In Some Places 
the Sides of the Alleys, and Some of the great Vaults, 
are lined and doubled withTimbers, where they thought 
the Pillars of Earth or Salt left for Supporting the 
Superior Weight might prove too weak. I observed 
in one Place, that a Sinking of the Earth Some Years 
ago had crufhed Some of the Baulks almoft flat, and 
made a Rent in the Salt Rock on the other Side, 
about nine Inches wide. 
Notwithftanding there is no Remembrance or Tra- 
dition of any remarkable Accident by the Falling-in 
of thefe Mines, yet they have lately discovered a 
Wooden HouSe, which muft have been Swallowed 
in very long ago. Thefe Mines were on Fire in the 
Year 1644.. but this Accident muft have happened 
long before that time j for they have a Plan of thefe 
Works, taken about 200 Years ago, with Pvcmarks
