no information from the study of that country, and will none 
of the members of either Society visit that District? Is 
there no Society at Chesterfield or Derby, with which we 
may correspond ? At all events, in addition to having 
obtained truly valuable information, the executors of this line 
of section would return refreshed with health from a tour in 
the picturesque dales of Derbyshire, and laden with fluor 
spars and marine shells to store our cabinets ; whereas they 
would return from the inhospitable regions of Saltersbrooke 
and Woodhead, where snow is frequently seen in July, half 
perished by cold and want of food, perplexed by the grit 
rocks they had seen, and I question whether any wiser for 
their journey. 
The Chairman having invited discussion, 
Mr. H. Hartop rose and said, — The section on which 
they had heard so very interesting a paper from his friend 
Mr. Thorp, was, as they had heard from the Chairman, 
brought before the Society on a former occasion. At that 
time he thought it would have been better to take a line to 
the south of that suggested by Mr. Morton. He felt, how- 
ever, some delicacy on this point, as he happened to live on 
the very line which he thought best, and as it might there-

recommend a line to which he would not have far to go. 
The line proposed by Mr. Thorp, would go through Roth- 
erham southward of the valley of the Don, but it would here 
be attended with a difficulty which he would point out. (Mr.

direction, and that below Rotherham, by a similar turn, they 
recovered their former direction.) Before, however, Mr. 
Thorp's line reached Rotherham, he would cross this great 
heave in the valley of the Don, which would be a very un- 
favourable circumstance, as the dip of the strata would be
