130 The Carboniferous Limestone of West Cumberland. 



Chjetetes. 



Chcetetes septosa, Edwards and Haime, enters in the Seventh Limestone 



and is fairly abundant throughout the series. 

 Ch. depressa, Edwards and Haime, occurs in the Fifth Limestone and in 



wide-spreading sheets in the higher beds of the Fourth Limestone. 



It is also abundant in the First Limestone. 



APPENDIX II. 

 List of Exposures of West Cumberland Limestones. 

 First Limestone. 



(a) At Langhorn, Bigrigg, immediately south of Langhom Farm, i& 

 a fairly large disused quarry in this limestone. About 20 yards 

 west of quarry the limestone can be seen in railway cutting where it 

 is overlain unconformably by Permian breccia. 

 (6) Small quarry behind Orebank House, Bigrigg, overlain by breccia. 



(c) Small opencast behind Bigrigg Moor houses. Old hematite workings. 



(d) Large disused quarry at Overend about a quarter of a mile south- 



east of Henstngham village. The limestone is here overlain by the 

 Millstone Grit. 



(e) Small disused quarry near Birks Farm, Cleator Moor. 



(/) Small exposure in railway cutting leading into Kelton Head Quarry,, 

 north-east of Rowrah Station- 

 Sandstones and Shales. 



The sandstones and shales separating the First from the Second Lime- 

 stones are exposed — 



(a) At Langhorn in disused hematite opencast. 



(b) At Overend quarry. 



(c) In railway cutting at Kelton Head Quarry. 

 Second Limestone. 



The Second Limestone is exposed xmderlying the sandstones and shales 

 at the three places mentioned above. 

 The Orebank Sandstone. 



(a) The best exposure of these beds, which consist of a series of sand- 

 stones and shales upwards of 70 feet in thickness, occurs in the old 

 hematite opencast between Langhom Farm and Orepit Cottages. 

 (6) It is badly exposed in railway cutting at Kelton Head. 

 Third Limestone. 



(a) Small remnant left on the top of Clints Quarry near limekiln on the 



Egremont-Whitehaven Road. 



(b) At Eskett in railway cutting behind Ennerdale Hall. 



(c) At entrance to Rowrah Hall Quarry. 



(d) At entrance to Kelton Head Quarry. 

 Fourth Limestone. 



The great extent to which this limestone is used in connexion with the 

 smelting of the hematite ores of the district, accounts for the many large 

 quarries at present being worked in it. 



The full sequence of the beds from the " White Beds " at the base to 

 the top of the " Junceum Beds " are exposed in one large and two small 

 quarries at Clints, whilst the " Rough Beds " and some of the beds above 

 are exposed in a series of small knolls in Gillfoot Wood and on the 

 western side of the Egremont-Whitehaven Road. 



At Yeathouse Quarry, near Yeathouse Station, Frizington, the beds 

 from the " White Beds " to the base of the " Saccammina Beds " are 

 exposed. 



At Eskett Quarry, {- mile east of Winder Station, and behind Ennerdale 

 Hall at Rowrah Head, and Rowrah Quarries near Rowrah Station, and at 

 Kelton Head Quarries, the full sequence is exposed, all of the beds being 

 accessible for examination. 



A small exposure of the " Rough Beds " occurs near Scalesmoor Farm, 

 Lamplugh.
