Mr. Farey’s Notes on Mr. Bakewell’s Geology. 363 
P. 130. his new System, as observed in my second Note on 
p- 60; Mr. B. seems, in forming this Class, to 
have been rather too ‘ well educated,” see his 
Note on p. 353. 
135, 1.1, been found under it*.—* “ Red sandstone, or 
sand-rock,”’ in this case, evidently refers to the 
different Red Marl strata, in or below the middle 
parts of the British series of strata, as observed in 
my 2d Letter (p. 104); and although the practical 
Colliers of the Ashby-de-la-Zouch Coal-field, 
and of some others perhaps, surrounded in whole 
or in part, by faulis, which have elevated their 
(denudated) Coal-measures, from too great a depth 
to be reached under the Marl beyond the fault, 
(see my Note on p. 142, and Rep. i. 174) may 
believe, and maintain with Mr. B. (see also pages 
134, 268, 273, &c.), that ‘Coal is never found un- 
der the Red Marl” (or red Sandstone), and may, 
as the Writer mentions in page 232 of your pre- 
sent volume (perhaps Mr. Jameson) consider it 
madness to seek for Coal, in districts composed 
of red sandstone,” or red Marl; yet in Somerset- 
shire (as well as in Lancashire, I believe, as Mr. 
B. hints, p. 135), the fallacy of this old rule has 
Jong been known. Until about 50 or 60 years 
ago, all the Coal-pits to the SW of Bath, had 
Shale, Bind, and Grit beds only in their sinkings, 
, and it was then confidently asserted, that the Red- 
ground or Marl to the East of them, entirely “ cut 
off” all the Coal-measures (sce Mr. B’s pages 
134, 268, 273, &c. and your 105th page, Note): 
but a practical old man, of the name of Bush, from 
an attentive examination of the edges of the strata 
in the gullies to the eastward, discovered, and 
maintained, that their Coal-measures regularly 
underlaid the red ground to the East ; and in the 
process of the workings, and sinking of deeper 
Pits, as steam Engines became more general, his 
opinion has been fully confirmed, and great num- 
bers of Coal-pits, in different valleys, between 
hills capt with Lias, (and even with Bath stone 
on this, in some instances) have since been sunk, 
through considerable thicknesses of Red Marl. 
These facts, induced the trial in a deep valley 
to the north of these, at Bath-Easton, which I have 
mentioned, Rep, i.116, and which has since been 
abandoned,
