252 Further Geological Queries. 



6th. Ill what direction and degree do the Coal-measures of 

 Tindal-fall dip? : what is the serifs sunk through in their Pits? ; 

 are there in the vicinity either eastward or westward, any consi- 

 derable masses or strata of Basalt in any of its varieties (not 

 Dvkes) ? ; and if so, where are they situated ])recisely ? ; In 

 what direction do thcv dip and take-cover ? ; and what are the 

 strata hasseting from under them, in an opposite direction?. 



An intelligent Gentleman, who has all his life resided in the 

 elevated country south of Jedburgh, and who, though no pro- 

 fessed Mineralogist, is well acquainted locally, with all " the tract 

 due west and north-west of the Cheviots," happening to call on 

 me a few davs ago, and to whom I shoued Mr. Winch's Map 

 and description of the Cheviots, in tlie Geological Transactions, 

 professed his ignorance of any coarse slaty Rocks (like those 

 about Hawick and Selkirk which he knows well) in the vale of the 

 Beaumont, or on Carterfell; although there are (he says) some 

 patches, or a narrow range of such coarse slaty Rocks, along the 

 south-eastern verge of Cheviot, although far less extensive, he 

 believes, than the '* Grauwakke slate " district, coloured there 

 in Mr.W's iNIap, who has written Carter-fell in the same, instead 

 of its true position, to the SW, facing the head of Reed Dale: 

 and certainly this Scotch Gentleman said, the coarse slaty Rocks 

 here, do not join on the surface, or near it, to those like them 

 about Hawick. I beg therefore to inquire, 



7th. Can the very lower part of the Coal, Sandstone, Shale 

 and Limestone series, sometimes called by Mr.Winch the " Lead- 

 mine Measures," which he represents as surrounding and lap- 

 ping on the north, the east, and the southern flanks of the Che-^ 

 viot mass, be in like manner traced continuously, on its western 

 side, from Kerryburn to Mindrum ? If so, by what route, ex- 

 actly? ; and what are the dips, at several points, in this range ?. 



For the theoretic opinions of Mr. W. or any other persons, as 

 to whether Basalt " owes its origin to n differenl cat/^e froni 

 the reiiularly stratified Rocks with which it is associated," the 

 Querist had not the most distant intention of asking: but his 

 wish was, and is, for the communication of precisely localized 

 fads, regarding the present positions and circumstances of this 

 and all others of the mineral Masses or strata, of which the 

 northern parts of England are composed, and for such he will ever 

 feel obliged. He will now however, not let slip the opportunity 

 of remarking, that after examining carefully, many score miles 

 of the ranges of Basaltic masses, he has uniformly found them, 

 us distinctly stratified and interlaid between regular strata, as 

 most of the latter are, with regard to one another : not one 

 anomaly as to Basaltic strata appearing, except in degree, from 

 what is very common with other strata.
