' ' dips 1 in 8 to the N W ; " or " dips N W 1 in 8 ; " that is imagining AC level, and 8 

 of any measure (as inches, feet, yards, fathoms) CB, or the perpendicular descent 

 or fall of the seam in that length, is 1 of the same measure. This T express on my 

 maps, by writing a small 8 at the point of the dart. I hope I shall soon receive a 

 long letter of neto facts and corrections from you, of the suggestions I have sent to 

 you, as to the structure of your interesting District, the technical mineralogy of 

 which is rather out of my way, but exactly in that of my friend Mr. Lowry, who 

 may perhaps give you some useful hints, as to the sale at or near home (perhaps at 

 Kendal, Penrith, Carlisle, Whitehaven, etc. ) of Strata Maps, coloured by you, as 

 I have recommended in my last. 



I am, dear Sir, 



Yours very truly, 



J. FAREY, Senr. 



In a second letter, dated March 17th, 1823, Farey asks Otley 

 numerous geological questions, and alludes to Jonathan's first meeting 

 with "Strata Smith," often called the Father of English Geology; he 

 says — " Mr. Smith's conduct, on your first meeting with him in summer, 

 182 1, affects me, much more with shame and regret, than with surprise. 

 Had he met me there, or any one else, who he knew had laboured at the 

 "knotty parts" he was examining, he probably would alike have shunned 

 us." . . . Smith and his nephew, John Phillips, afterward the well- 

 known and accomplished Professor, stayed shortly after for some time 

 at the Queen's Head, Hesket Newmarket, having business in connection 

 with the High Pike Mine.

 Dear Sir, — 



My apology is due to you for not sooner answering your kind letter of the 

 12th December, 1821. For some weeks after that date I had not seen Mr. W. 

 Forster's book, and could not therefore immediately understand and reply to j'our 

 remarks thereon ; and in the meantime, I was fortunate enough to be employed by 

 the Commissioners of His Majesty's Woods, Forests, &c., to investigate and report 

 on the Slate rocks and quarries in the vicinity of Bangor, in North Wales ; which 

 has given me a good opportunity of comparing the stratification there with that 

 which surrounds you in Cumberland : confirmatory of the important fact which 

 you taught me (having myself never seen about the western halfoi your mountains)
