From William Stevenson to William Kemp   29 May 185[2]


29th. May 18⁠⟨⁠52⁠⟩⁠

Mr. Wm. Kemp | Galashiels

My Dear Sir,

I was much gratifie⁠⟨⁠d⁠⟩⁠ by the receipt of your kind letter of the 19th. curt., the more especially as from your long silence I was afraid that you might not be enjoying such good health a I would wish.— I am happy how⁠⟨⁠ever⁠⟩⁠ to learn that you continue wel⁠⟨⁠l⁠⟩⁠ in other respects, but for the shak⁠⟨⁠ing⁠⟩⁠ of which you complain.— I belie⁠⟨⁠ve⁠⟩⁠ a change for a week or two w⁠⟨⁠ill⁠⟩⁠ do you much good.— Some rambl⁠⟨⁠e⁠⟩⁠ among the mountains, hammer i⁠⟨⁠n⁠⟩⁠ hand, would tend more to stea⁠⟨⁠dy⁠⟩⁠ your nervous system than any thing else that I know of.—

I am getting on very wel⁠⟨⁠l [one line excised] b⁠⟩⁠usiness matters.— I have however ⁠⟨⁠h⁠⟩⁠ad two or three good field days ⁠⟨⁠(2⁠⟩⁠ of them Sundays, but tell it not in Gath).— ⁠⟨⁠O⁠⟩⁠n one of these occasions I spent ⁠⟨⁠the⁠⟩⁠ day in examining the coast from ⁠⟨⁠E⁠⟩⁠yemouth to Burnmouth.— The phenomena presented there are most ⁠⟨⁠in⁠⟩⁠teresting and shew the immense ⁠⟨⁠p⁠⟩⁠ower of the forces by which the ⁠⟨⁠g⁠⟩⁠reywacke strata there have been ⁠⟨⁠th⁠⟩⁠rown into their present positions.— ⁠⟨⁠Th⁠⟩⁠ere the complicated foldings of ⁠⟨⁠th⁠⟩⁠e strata are beautifully exposed.— Not only do we find the ordinary ⁠⟨⁠s⁠⟩⁠uccession of parallel or nearly parallel ⁠⟨⁠An⁠⟩⁠ti- & Syn-clinal axes,—the result ⁠⟨⁠of⁠⟩⁠ lateral pressure,—but we ⁠⟨⁠h⁠⟩⁠ave instances of another phenomenon ⁠⟨⁠w⁠⟩⁠hich I have not elsewhere observed, ⁠⟨⁠v⁠⟩⁠izt., a turning up of the axes them⁠⟨⁠s⁠⟩⁠elves (here very close set) into ⁠⟨⁠a⁠⟩⁠ vertical, instead of a horizontal ⁠⟨⁠[one line excised]⁠⟩⁠ has evidently been produced by great pressure in the direction of the axes, or from NE to SW.— Thi⁠⟨⁠s⁠⟩⁠ I would call terminal pressur⁠⟨⁠e.⁠⟩⁠ The greywacke system is at this place brought to a sudden terminus, being cut off and thrown down by a great cross fracture⁠⟨⁠.⁠⟩⁠ Disturbing movements have taken place along this line at more than one epoch,—for it is eviden⁠⟨⁠t⁠⟩⁠ from the manner in which the strata of graywacke slate are bent over the sharpest axes without having been broken, that they mu⁠⟨⁠st⁠⟩⁠ have been in a soft & high⁠⟨⁠ly⁠⟩⁠ plastic condition, at the early period when this was effected,—and t⁠⟨⁠he⁠⟩⁠ newer strata of O.R.S. & lower carboniferous have also been di⁠⟨⁠s⁠⟩⁠located in nearly the same direction.— The greywacke here is different from that of any oth⁠⟨⁠er⁠⟩⁠ part of the Lammermuirs, aboun⁠⟨⁠ding [one line excised]⁠⟩⁠ this respect it resembles that of ⁠⟨⁠H⁠⟩⁠assendeanburn, of which it is ⁠⟨⁠m⁠⟩⁠ost likely the true equivalent, the ⁠⟨⁠b⁠⟩⁠earing of the two localities from each ⁠⟨⁠o⁠⟩⁠ther corresponding with the direction ⁠⟨⁠of⁠⟩⁠ the line of strike. I found ⁠⟨⁠n⁠⟩⁠o decided organic remains, but markings were frequently seen most provokingly like some strange organic forms.

On Sunday last I had an ⁠⟨⁠e⁠⟩⁠xcursion up the Watch Water ⁠⟨⁠to⁠⟩⁠ near its source. I found in ⁠⟨⁠t⁠⟩⁠heir proper position the slates ⁠⟨⁠w⁠⟩⁠hich are the equivalents of those ⁠⟨⁠o⁠⟩⁠n the Dye from which I last year procured a piece of a graptolite. On this occasion I was unsuccessful in my search for graptol⁠⟨⁠ites⁠⟩⁠ but found plenty very curious markings. Some interesting sect⁠⟨⁠ions⁠⟩⁠ are seen in the course of the Watch, shewing very beautiful ⁠⟨⁠[one line excised]⁠⟩⁠ near the West Side of Derrington Law (the larger of the two). I had the good fort⁠⟨⁠une⁠⟩⁠ to fall in with the junction of the porphyry with the O.R.S.,—wh⁠⟨⁠ich⁠⟩⁠ I have in vain sought for for some years past,—there being n⁠⟨⁠o⁠⟩⁠ deep sections exposed and the alluvial cover near the junction being thick.— The junction referred to is seen in a section m⁠⟨⁠ade⁠⟩⁠ by a small burn, and though the rocks are only exposed to a depth of 3 or 4 feet at most, ye⁠⟨⁠t⁠⟩⁠ some highly interesting metamorp⁠⟨⁠hic⁠⟩⁠ phenomena are exhibited.— It i⁠⟨⁠s⁠⟩⁠ therefore now demonstrated tha⁠⟨⁠t⁠⟩⁠ the Derrington porphyry is mor⁠⟨⁠e⁠⟩⁠ recent than the Old red Sands⁠⟨⁠tone,⁠⟩⁠ thus confirming the opinion I hav⁠⟨⁠e⁠⟩⁠ long held regarding it.— The clayst⁠⟨⁠one⁠⟩⁠ dykes of the conglomerate as well as those seen intersecting the re⁠⟨⁠d⁠⟩⁠ sandstones on the Blackadde⁠⟨⁠r⁠⟩⁠ above Greenlaw are also referr⁠⟨⁠ed [one line excised]⁠⟩⁠

A few weeks ago I had an ⁠⟨⁠e⁠⟩⁠xcursion with Mr. Turnbull ⁠⟨⁠of⁠⟩⁠ Abbey St. Bathans & Mr. Rose ⁠⟨⁠t⁠⟩⁠he Mineralogist.— We inspected ⁠⟨⁠t⁠⟩⁠he old copper workings near Elmford & having set some men to work, discovered a ⁠⟨⁠c⁠⟩⁠onsiderable quantity of sulphurat⁠⟨⁠ed⁠⟩⁠ carbonate of copper in a sort ⁠⟨⁠o⁠⟩⁠f string vein running nearly East & West.— The copper occurs ⁠⟨⁠i⁠⟩⁠n a breccia formed of angular ⁠⟨⁠f⁠⟩⁠ragments of greywacke which ⁠⟨⁠h⁠⟩⁠ad accumulated (under water) ⁠⟨⁠i⁠⟩⁠n a fissure opened in connection with the ⁠⟨⁠g⁠⟩⁠reat dislocation which crosses ⁠⟨⁠t⁠⟩⁠he Lammermuirs at this place. It is questionable if the ore ⁠⟨⁠w⁠⟩⁠ill be found in sufficient ⁠⟨⁠q⁠⟩⁠uantity to pay, but upon the ⁠⟨⁠w⁠⟩⁠hole the appearances are ⁠⟨⁠[whole line excised]⁠⟩⁠

Now, my dear sir, sin⁠⟨⁠ce⁠⟩⁠ I have got a house of my ow⁠⟨⁠n⁠⟩⁠ I should like extremely if you would honor me wit⁠⟨⁠h⁠⟩⁠ a visit for a few days in th⁠⟨⁠e⁠⟩⁠ course of the Summer.— Try what you can do this Sea⁠⟨⁠son⁠⟩⁠

Hoping to hear from you soon, and with kindest rega⁠⟨⁠rds⁠⟩⁠ and best wishes for the welfa⁠⟨⁠re⁠⟩⁠ of yourself & Family, | I remain | My Dear Sir | Yours Ever Truly | Wm. Stevenso⁠⟨⁠n⁠⟩⁠

P.S. Please remember me to Dr. Boy⁠⟨⁠ ⁠⟩⁠ I thought much of him for the shor⁠⟨⁠t⁠⟩⁠ time that I had the pleasure of his ⁠⟨⁠[one line excised]⁠⟩⁠ ⁠⟨⁠I⁠⟩⁠f I had an opportunity I should be ⁠⟨⁠h⁠⟩⁠appy to send the M.S. of my lecture ⁠⟨⁠f⁠⟩⁠or your perusal.
