OF CORNWALL. 57 
At Tehidy, the feat of Francis Baffet, Efq; the rooms fhook, 
and the grounds, without doors, were obferved to move. The fhock 
was felt fenfibly at Redruth, St. Columb, Bodman, &c. along to 
Camelrord, which is about ninety miles from the idles of Scilly. From 
Marazion, Eaftward, it was felt at feveral places, in like manner, as 
tar as Loftwythyel : but at Lifkerd, about ten miles Eaft ofLoftwy- 
bu , C fahltl7 P erceived > and that by a few perfons : it 
was ltill lefs fenfible at Loo and Plymouth, “ fcarcely fufficient to 
“ excite curiofity or fear b .” 
The times of its duration were various. At Keneggy, we thought 
t e noife could not have lafted above fix feconds ; at Trevailer, not 
two miles diftant to the Weft, it was thought to have lafted near 
half a minute ; in the parifh of Gwynier, half a minute ; at Ludg- 
van three miles Eaft of Penzance, the noife was rather longer than 
hdf a minute ; but the fhaking felt in the garden, and oblrved in 
the houies, lhort and momentary. In Germo great-work, feven 
miles Eaft of Penzance, it lafted only a few feconds ; but in the 
iiles of Scilly, it was computed at forty feconds. 
So was this Earthquake felt in towns, houfes, and grounds adja- 
cent; 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 fhock was fenfibly 
felt eighteen fathom deep ; in the mine, called Bofcadzhil-downs, 
more than thirty fathom. 
At Huel-ridi mine, in the parifh of Lannant, people faw the 
earth move under them, firft quick, then in a flower wavy tremor ; 
and the ftage boards of the little winds or fhafts, twenty fathom 
deep, were perceived to move. 
In Herland mine, commonly called the Manor, in the parifh of 
of Gwynier, the noife was heard fifty-five and fixty fathom deep, 
as if a ftuddle had broke, and the deads d were fet a running : It 
was nothing like the noife of thunder. 
In Chace-water mine, the fame noife was heard, at leaft feventy 
fathom under the furface. J 
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 fvvift, and apparently horizontal tre- 
mor ; its continuance was but for a few feconds of time, not like 
t under, but rather a dull, rumbling, even found, like deads run- 
mng under ground. In the Smith’s fhop the window-leaves fhook, 
and the flaring of the houfe cracked ; the Whim-houfe fhook fo
