tion through the to>vnships of Cudworth, Darfield, Billingley, 
and Bolton-upon-Dearne, to the Magnesian limestone ridge ; 
but Mr. Thorp is of opinion that a better development of the 
strata may be had by curving the line, in WooUey, to the 
North-East, and passing through Notton, Roystone, Shafton, 
Brierley, Great Houghton, and Clayton-in-the-Clay, to the 
Magnesian limestone. There is, however, little geological 
interest between Notton and the limestone ridge, (so far as 
regards coal beds,) there being only two workable seams. 
" In conclusion, I may observe, that I recommend this 
line to the attention of the Societ}^, because I think it crosses 
over more bold hills, descends deeper vallies, and conse- 
quently intersects the outcrops of more Coal beds and strata 
than any other line I could suggest, in the middle part of the 
coal-field. It also crosses the country at those places where 
the minerals are known to be of the best quality, and where 
they are most worked, particularly in the valley of the Cal - 
der." 
The Committee recommend that the section should em- 
brace the various details mentioned in the Committee's Re- 
port, at Leeds ; namely, that the surface of the country 
should be carefully levelled and laid dovra ; that towns, vil- 
lages, roads, rivers, canals, collieries, boreholes, and town- 
ship boundaries, should be noticed ; that vertical sections of 
pits and boreholes should be delineated ; that the intersec- 
tion of the " basset" or " outcrop" of coal, ironstone, and 
other strata, should be marked down ; that the crossing of 
" faults," or " throws," should be registered, and the extent 
of the dislocation stated ; and that the continuous position 
and dip of the different beds should be drawn as far as they 
can be correctly ascertained. 
The Committee are further of opinion that, in order to 
make the proposed section as practically and generally use- 
fill as possible, it should be accompanied by a map or plan 
of the fields, &c., as before mentioned, for a distance of five
