next directed to a line of section pointed out by Mr. Thorp, 
in a communication read by him at the Societj^'s last meet- 
ing, held in Bradford. This line commenced in the Peak 
of Derbyshire, and crossed the Yorkshire coal field south- 
ward of Sheffield and Rotherham ; and although it seems 
to furnish much geological information, yet the Committee 
consider it too far removed from the sphere of the Society's 
operations to be adopted with advantage. Nevertheless, they 
feel assured that a work of so much interest will not remain 
unnoticed, but will, ere long, occupy the attention of geolo- 
gists resident in the neighbourhood of Sheffield and Chester- 
field. 
Another route has subsequently been suggested by Mr. 
Holt, commencing near Halifax, and proceeding in a South- 
Eastern direction towards Doncaster, which, while it deve- 
lopes our own Coal measures to the fullest extent, does not 
altogether lose sight of the original object; for it is supposed 
that, if this line were continued Westward to the Penine 
chain, it would intersect certain strata on the Eastern side 
of that ridge, which are already proved to be identical with 
certain other strata on the Western side, and thus the York- 
shire section and the Lancashire section might be said to 
have a common point of departure, geologically speaking, 
though not geographically. 
Under these impressions, the Committee have determined 
to recommend to the Society the adoption of the last-men- 
tioned line ; and they further consider it advisable to confine 
the attention of the Society exclusively to that part of the 
section which traverses the Coal measures, without regard to 
the Magnesian Limestone and Red Marl deposits, that lie 
farther to the East ; in the hope that, by a concentration of 
the Society's energies to one portion only, we shall more 
speedily and more accurately carry out the fundamental 
object of the Society, namely, the thorough examination and 
elucidation of the Yorkshire Coal field. ^
