WITH THE YOEKSHIRE COAL-FIELD. 
Ill 
The committee recommended that the section should embrace 
the various details mentioned in the committee's report at Leeds, 
namely, that the surface of the country should be carefully levelled 
and laid down, that towns, villages, roads, rivers, canals, collieries, 
boreholes, and township boundaries should be noticed, the vertical 
sections of pits and boreholes should be dehneated, that the inter- 
section of 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. It was also recommended 
that a map or plan of the ground on each side the liue of section to 
the extent of five or ten chains should be made, and that the scale 
of lengths should be 264 feet (or 4 chains) to 1 inch, and that of 
depths be 40 feet to 1 inch. It is further requested that members 
who may furnish details of sinkings or borings should draw them on 
an uniform scale of 8 feet to 1 inch. The section as proposed was 
25 miles in length, and comprised between 3,000 and 4,000 feet of 
strata. ''In a work so extensive it is obvious that the combined 
talent and exertion of all the geologists in the society will be required 
to accomplish it. The committee had the satisfaction to announce 
that the following gentlemen had volunteered to assist in the prepara- 
tion of the several portions of the section: — In the townships of 
Northowram and Hipperholme, ]\Ir. Martin ; in Clifton and Harts- 
head, Mr. Holt ; in Mirfield, Mr. Bull ; in Thornhill and Shitlington, 
Mr. Briggs ; in Bretton, Crigglestone and "Woolley, Mr. Morton and 
Mr. Embleton ; in Notton, Roystone and Shafton, Mr. Hall ; in 
Brierley and Great Houghton, Mr. Hartop ; and in Clayton and South 
Elmsall, Mr. Thorp. 
At this time the Midland Railway was in progress, designated 
the North Midland at that time, and the council of the society made 
a request to Mr. Swanwick, the engineer to the line, that he would 
allow a number of the members to inspect the cuttings along the 
route. This permission was readily granted, and the 25th June, 
1840, fixed for the visit. The members met at the Scarborough 
Hotel, at Leeds, and breakfasted between 6 and 7 in the morning.
