pregnated with ferruginous matter, depositing an ochre, which is 
sometimes used in the pottery. 
It appears, upon inquiry, that the space of time from the Bovey 
Coal being first worked, to the present, is a period of upwards of 
ninety years. The annexed sketch shows the arrangement of strata. 
The white denotes the argillaceous strata, the black points out the 
strata from which the coal is procured ; and the lightly shaded are 
strata containing an inferior kind of coal, not worth taking up. 
OBSERVATIONS. 
The spot now worked for the Bovey Coal, is situated in low 
boggy ground, which extends several miles : it is said to be the 
lowest in the county, but this is an assertion not true. To the south 
of the shaft, about a quarter of a mile, is a bog, from which has 
been taken (several feet below the surface) many trees of the fir 
kind ; several eighteen inches in diameter, together with pine-nuts, 
but no traces of coal. 
This is the account with which our friendly guide favoured us, 
and to us it has proved highly gratifying; since we have been 
thereby enabled to compare the present state of this curious spot, 
with that in which it existed near fifty years ago, according to the 
description given by Dr. Milles. To you, for the same reason, it 
cannot but prove particularly acceptable. 
Yours, &c.
