the Ihaking felt in the garden, and obferved in the 
houfes, fhort and momentary. In Germo great Pin- 
work, feven miles eaft of Penzance, it iafted only a 
few feconds ; but in the ifles of Scilly it was com- 
puted at 40 feconds. 
Thus was this earthquake felt in towns, houfes, 
and grounds adjacent but ftill more particularly 
alarming in our mines, where there is lefs refuge, 
and confequently a greater dread from the tremors 
of the earth. 
In Carnorth adit, in the parifh of St. Juft, the 
ftiock was fenfibly felt 1 8 fathom deep ; in the mine 
called Bofcadzhill-downs, more than 30 fathom. 
At Huel-rith mine, in the parifh of Lannant, peo- 
ple faw the earth move under them, firft quick, then 
in a flower wavy tremor j and the ftage-boards of 
the little winds or fhafts 20 fathom deep were per- 
ceived to move. 
In Herland mine, commonly called the Manor, 
in the pari ill of Gwynier, the noife was heard 55 
and 60 fathom deep, as if a ftuddle (3) had broke, - 
and the deads (4) were fet a running. It was nothing 
like the noile of thunder. 
In Chace- water mine the fame noife was heard, 
at leaft 70 fathom under the furface. 
At Huel-rith mine, near Godolphin, the noife 
was feemingly underneath. I felt (fays the director 
of the mine) the earth move under me with a 
prodigious fwift, and apparently horizontal tremor: 
its continuance was but for a few feconds of time.
