58 Mr. Wiiliam Smith’s Geological Map. ‘ 
xxxixth vol. p. 498, and J could I think from other districts, 
increase the list. What Mr. B. calls ‘‘ subterranean” Forests,» 
p. 11, 205, and 269, viz. stumps of Trees buried in peat, are. 
not peculiar to the Lincolnshire and Yorkshire Coast, or 
even to his ‘ low district,” but in every situation from the: 
Land’s-end to John o’ Groats’, on both sides of the Island; . 
on flat shores which have neither wasted or increased by the 
action of the currents, in modern times, the same pheno- 
menon and others occur, indicative of the gradual rise of the 
Sea. In Sutherland this is proved, by the waves having 
lately covered with Beach, the hillocks of Coal-pits worked 
in Queen Elizabeth’s Reign. In the Manuscripts of the 
late ingenious Lecturer, Mr. Waltire, his observations on 
this phenomenon, on the various Coasts of England, and 
also of Holland, which he went to examine, are detailed, as 
J have been informed. Westminster Hall, Boston Church, 
and perhaps other fine old buildings, being now often 
flooded some feet deep by the increasing tides, furnish other 
proofs of the same thing. } 
The contemptuous boast by Mr. B. (p. 45 of your xlth 
val.) of his ignorance of what Mr. Smith may bave done, 
towards a Map of the Strata of England, (for as to faults, 
he had no ground for coupling me and Mr. Smith, as ap- 
pears from your xxxviith vol, p. 441) surely does not seem 
much calculated to raise his character as a philosophical 
enquirer after ¢ruth, or as a liberal historian of the labours 
of his cotemporaries *, to say nothing of the interested views 
which might be taken of such conduct, from one profess 
sional man towards another. 
I am extremely happy, however, to be able to state, that 
the public are not likely to remain long ignorant of Mr. 
* Mr. B’s eagerness to renew his attacks on the subject of Faulls (p. 212 
and 283) would not permit him to appear totally to overlook me as he has 
done Mr. Smith, and it is not unworthy of remark, that in the only instance 
in which Iam expressly referred to, for a single Geological fact or inference, 
#t has been done in an unfair way.—After the account of the Derbyshire . 
Mineral Veins had been written for my Report, Mr. Joshua Gregory, the 
very able and respectable overseer of the Gang Mine near Wirksworth, 
happening to be in town, I either read orrelated to him all the most material 
points therein; on which occasion, and after [had any opportunity of 
making inquiries of other Miners throughout the county, 2s in most, if not on 
every other material point was expressly done; Mr.Gregory stated, that “some 
of the thickest of the clay waytoards” divide even the largest Veins, as com- 
pletely as the Toadstone strata do” (Report I. 245), and for the reasons. 
above stated, I added, “as I am informed by Mr. Joshua Gregory, an expe- 
rienced miner.” Yet Mr. B. p. 226, thus refers to the passage, ‘* Mr. Farey” 
says, “ that where the beds of lime-stone are divided by seams of clay, these 
seams frequently cut off the vein as eftectualiy as the thick beds of Yoad- 
stone,” omitting all mention of Mr. Gregory, or his and my distinction 
that only ‘ some of the thickest” wayboards, were here spoken of.
