tion of the coal. The iron pyrites is met with very frequently. 

 There are springs impregnated with ferruginous matter, depositing 

 an ochre, which is sometimes used in the pottery. 



It appears, upon enquiry, 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 descrip- 

 tion given by Dr. Milles. To you, for the same reason, it cannot 

 but prove particularly acceptable. 



Yours, &c.
