812 E. WILSON ON THE SOUTH-SCARLE SECTION, 
61. On the Soura-Scarte Section *. By E. Wrutsoy, Esq., ¥.G.S. 
(Read June 25, 1879.) 
Ar South Scarle, a point about halfway between Newark and 
Lincoln, an unsuccessful boring for coal some short time ago dis- 
closed a most interesting, but, so far as its lower portion was con- 
cerned, somewhat puzzling geological section. The object of this 
communication is to identify, if possible, the lower rocks passed 
through in these borings. 
The following generalized section is quoted from a paper “ On a 
deep Boring for Coal at Scarle, Lincolnshire,” by Prof. KE. Hull, F.R.S., 
F.G.S. (see Proc. Inst. Civil Engineers, vol. xlix. part iii.) :—

Down to 26 feet in the Lower Magnesian Limestone the above 
classification of the Scarle cores appears to be approximately correct. 
Below that depth, however (1827 feet), there came up from 50 to 
60 feet of a very hard dark grey to black rock, generally oolitic, 
though apparently unfossiliferous, the analysis of which showed it 
to be an argillaceous dolomite. This was succeeded by 16 feet of 
sandy (?) sediment too loose for cores; then came 118 feet of grey 
earthy limestones or calcareous shales, with a foot or so of greenish 
grit or breccia at the base. Last of all (at 2020 feet), compact red 
or purplish-red clays with nodules of hematite were penetrated to 
a depth of 10 feet. On seeing the first specimens of the “grey 
earthy limestones,” Professors Ramsay and Hull both came to the 
conclusion, founded on lithological grounds, that these rocks were 
to be referred to the Lower Yoredale series. The succession below, 
however, of fine greenish grit, or breccia, and chocolate-coloured clays 
proved very puzzling; and the fact of such strata not being known
