nortli to sontli. At, tlie soiitli-western end of thin track, 

 near Binoga,r, tho Mountain Limestone and tlio Coal-measures 

 are separated l)y a narrow nock of Conglomerate, less than a 

 quarter of a mile across, wlii(;h is also divided again I'rom a 

 spur by a narrow strip of Millstone Grit, which also helps 

 to bridge over, at this point, the space between the Coal-, 

 measures and tho Limestone. 



The Bath and. Bvercreech .Railway, between Chilcompton 

 and Binegar, runs through, the Conglomerate for about two 

 miles ; and some very good sections are laid bare in some 

 of tho cuttings, ]iarticularly near tho bridge on tho road 

 from Wells to Chilcompton. As far as the author remem- 

 bers, there were no boulders found in these cuttings ; but 

 the Conglomerate was composed of pebbles u]) to about two 

 inches in length, cemented together very closely, and very 

 dark in colour. Although the before-named railway crosses 

 the Mendips very near their highest point, this was the 

 only Conglomerate passed tlirough in its entire length of 

 twenty-six miles, and it almost escaped altogether, only 

 I)assing along the north-west edge of the strata. It 

 is wortliy of note that this railway throughout, although ■ 

 I'ising upwards of 7U0 feet over tho Mendips, passed lor 

 twenty-one miles through Oolitic and Triassic strata. 



A friend of the author's recently, in buihling a house 

 near the foot of Worleberry Hill, on the south side of it, 

 at Weston-super-Mare, in excavating a site for a stable 

 through what was expected to have been Limestone, came 

 upon a ca])ital bod of Dolomitic Conglomerate of the Cleve- 

 (ton ty])0, from wliich he had the house built, instead of 

 from tho Mountain Limestone, as had been intended. The 

 Coiigioniei-ato is very light in colour, and, at a distance, 

 the house has the a])])oarance of being l)uilt of the Inferior 

 Oolite.
