the Strata of the Vicinity of Bridlington. 201 
Bridlington Harbour, on the coast of Yorkshire, three occasional 
Visitors of that place, Dr. John Storer, Mr. James Watt*, and 
Mr.Gavin Inglis, have offered their several conjeciwres. Mr.Milne, 
a resident, has done the same, and Mr. Hume has analysed its 
waters,without the facts of the stratification, of that part of the 
country, having sufficiently transpired, to enable myself and others 
of your Readers, who have never had the opportunity of ex- 
amining that part, to form any safe opinion. My object there- 
fore is now, to request the favour of Mr. Winch, whom I have 
understood to intend an examination this Summer of the northern 
part of the Yorkshire Coast, and I hope of this part also, and any 
other practical Investigators of the strata, that they would an- 
swer the following queries, through the medium of your pages, viz. 
Ist, Is the “‘ very solid Clay” through which the borer passed 
28 feet (vol. xlv. p. 433) in reality a bed of alluvial Clay?; 
as the bed of “ cretaceous flinty Gravel,” 15 feet thick, 
through which the borer is said to have passed, next after 
the Clay, may be supposed to indicate; owing to the fact, 
indisputable among practical Men, that real Gravel, is not 
found under any regular Strata: or, | 
2d, Is the Clay above mentioned, an undisturbed stratum? ; and 
the flints which are mentioned, as occurring in Gravel, in 
reality, the fragments of nodules of Flint broken by the 
boring chisel, which were dispersed in the Marl or soft 
Chalk which was bored through, 15 feet, before a larger 
nodule, or a continuous bed of flint, stopped the further pro- 
gress of the boring, into the Chalk Rock beneath?: or, 
instead of their being real Flints, which were bored up, were 
they not chert nodules, broken perhaps by the auger? and 
**the solid rock” which stopped the boring, concretion 
of a bed of the Sand, into the stone, usually called Gray 
Wethers?: or, 
3d, Instead of the Clay which was bored through, being part of 
the Plastic, Potters’, or Brick Clay, regularly covering the 
upperChalk (sometimes without, but more commonly with, 
a Sand intervening) as I have supposed in the last query: 
may it not form a stratum, between the upper and lower 
Chalk?: if it be correct, that -the same stratum of Clay, 
stretches up the Woids, so as to confine down the water in 
the Chalk around the Gipsies Springst. Because, if it be
