338 Remarks and Queries on llie Slrailfudtlon of Lancashire, 



shire near Ttigleton, past Hornby to Lancaster Common, 

 (p. 278), the Limestone Kock ol" Chipping and Clithcroe, 

 is not a different one from that i)f Dakon (not Daiton as 

 engraved), C;l»-tmel, VVarton, &c.? having this coal seam, 

 and perhaps nearly the whole of the shale and grit (brown) 

 between them ? or are ihey one rock and the connexion 

 complete through Yorkshire and Westmoreland, having 

 the brown upon it W., in a sort of trough or basin ? Does 

 rot the Limestone of Kendal, Cartmel, and Daiton lay upon 

 the Slate, &c. (green) where these districts adjoin each other 

 across Lancashire? and does not this Limestone Rock, af- 

 ter crossing the Duddon River, proceed somewhere near, 

 Kavenglass, Egremonl, Cockermouth, 8cc. in Cnmberland ? 

 overlaying the Slate, 5:c. to its East? or does the slate in 

 any part of this course, by approaching the coast, push the 

 Limestone out to sea? does not the Coal-field of White- 

 haven and Workington, &c. overlay this Limestone Rock, 

 to the East of these places ? and how far South and North, 

 and through what villages, can this junction of Coal-

 stone Rock, by approaching the coast, push these Coal- 

 measures out to sea?

 my paper in the recent PhilosophicalTransactions above al- 

 luded to. Dr. C. will be enabled to comprehend more fully 

 the objects of my several inquiries, and which I trust will 

 appear of such importajice to him, and others among your 

 readers, as soon to procure answers to them. 



The Maps and Sections, and other mineral documents in 

 the possession of the late Duke of Bridgewater's agents at 

 Worsley, and those in possession of Francis Astlcy, Esq.*, 

 of Diickingfield Lodge, Cheshire, are unusually extensive 

 and complete, I believe; and I doubt not, but on proper ap- 

 plication by Dr. C. or any other gentleman, who would 

 kindly undertake the task of collecting and arranging these 

 important materials, that the gentlemen alluded to, and the 

 other Lancashire coal -owners and their leasees, would per- 

 mit the necessary extracts and copies to be taken, with the 

 same readiness which I have uniformly experieiiced, in all
