256 Mr. Farey’s Notes on Mr. Bakewell’s Geology. 
[P. 265] Coal-measures occupy the surface, mentioned in my 
Note on page 108, and numerous large blocks of Basalt 
seattered pretty generally in- the alluvium (derived probably, 
from the ruins of the eastern end of this Dyke, in the Sea), 
there seem no facts to show the existence of Basalt wnder this 
district,for the Alum Shale extends deeper than a boring could 
be madé on theCoast near Mulgrave-Castle, (Mr. B. p. 266, 
and my Note thereon) and to the northward, to which the 
measures are rising, and Red Marl and Gypsum appear, near 
the mouth of the Tees ; these I have formerly supposed to be 
separated by a great fault? P. M. xxxix. p. 95, and towards 
the” bottom of the note in p, 96, have suggested, other 
queries respecting this Red Marl, one of which appears to 
me of greater importance, since reading an account of the 
strata in Gothland, in Dr. Thomson’s Travels in Sweden ; 
where, evidently, I think, the Danby-Dale Coal-field occurs, 
(and not that of Newcastle, as is\there said) N of Hessing- 
borg: the Coal-field near Boulogne, described in the 2d 
Lidit. of Williams’s Min. King. il. p. 335, is with difficulty 
referred to the Danby-Dale, or to any other of our Coal- 
fields, from the particulars there given; it seems however 
to occur in the eastern end of our great south-eastern de- 
nudation, (P. M. xxxv. p. 130) below the chalk, but how 
far? it is extremely interesting to know, more accurately : 
perhaps some of your Readers can supply more particulars 
of this part of the French Coast, and of the southern part 
of Sweden, &e. Do not these Coal-measures also appear 
ucross the northern extremity of Jutland, north of the Vi- 
borg district ? Do they not occur on the north-eastern side 
of Bornholm Island, in the Baltic? Do not lifted and de- 
nudated parts of these Coal strata appear at Rehburg on 
the NW, and Osterwald on the SE of Hanover? and again 
near Aix-la-Chapelle and near Liege? see M. De Luc’s Geo, 
Trav. in France, &c. vol. i. pp. 342, 345, 365, 366, and 
260 ; Kirwan’s Geo. Ess. p. 305, and Parkinson’ s Organic 
Remsiy/181.001 have mentioned, Po ME xXx? pe 100 N, 
the probability, that very thin seams of Coal, belonging to 
this field, have been noticed in the wells on the north side 
of Battel, in Sussex. Mr. Charles Smith, a Coal-master 
in Yorkshire, lately informed me, that about the year 1800, 
he sent some of his Colliers to Ashdown Park, in Sussex, to 
bore there for Coals, for his friend Thomas Bradford, Esq. 
and that in boreing 150 yards, they passed through nine 
thin seams of Coal ! which probably therefore belong to this 
Danby-Dale Coal-field? So may the Coal in Portl and 
Island, and at Kimmeridge, which I have not seen.
