bring their line up to the millstone grit, it would be no dis- 
advantage if they did not terminate at the same point. The 
line he should recommend was neither north nor south, but 
that which would best develope the construction of the strata 
between the millstone grit of Yorkshire and that of Lanca- 
shire. He thought the line across Derbyshire would be a 
very interesting one, and he hoped it would at some future 
time be undertaken. But they appeared there as a West- 
Riding Geological Society, and whilst he should be exceed- 
ingly glad for theirs to join the Lancashire line, he did not 
think that they ought to go away from the best point, and go 
across Derbyshire in order to do so. In the line which he 
(Mr. Hartop) had pointed out, there would be one advantage, 
namely, the use of the Wentworth House section, which the 
geological world had had so many years before them, which, 
although not quite correct throughout, was still exceedingly 
accurate, considering the knowledge which existed at the 
time it was made. He thought he might say that that sec- 
tion had made more geologists in the West-Riding than any 
other yet produced. They had had the opportunity of ex- 
amining the country where that section was originally formed, 
and since that period it had been corrected, and was now as 
good as could be obtained. This subject, he was aware, to 
a meeting like the present, was a very dry one, and therefore, 
he proposed they should have a meeting in the evening, in 
order to discuss the matter more fully.

The paper which I have very inadvertently engaged to bring 
before you, and for which I most sincerely solicit your kind 
indulgence, though originally designed for a very different 
company, has on the present occasion received the title of
