Dear Sr,
I recd. yours of 10th Inst. for which I am greatly obligd to you, & as for ye Honour & Honesty of London I never had any great opinion of it, but it abounded in good fellowship when I lived (or rather died) there, for I was sufficiently mortified by virtue of many glasses &c. &c. &c. Nid yw'r Corph etto gwedi dyfod i'w gwbl rinwedd, ond mae'n cryfhau beunydd ag rwy'n meddwl am fyned i drin Corph Benyw o Sir Benfro ar fyrder, ond nid mewn Anuwioldeb eithr fel Joseph Andrews gynt gida Fanny, - Hynny yw os deil yr arfau i'r fath ymladd (a mae arnaf eisiau ei treio ar ryw Elynion eraill yn y wlad hon. Nid wyf i aros yma oddiar wythnos to set our wheels a going. I have brought money here and we have a glorious prospect of Ore, but have not raisd much, my business hath been preparing & opening old works hitherto. The next spring will shew wonders.
If you are askd any Questions about our Cwmsymlog mine, as I Expect some of our Acquaintance here will; I desire the answer may be either Ambiguous, or that it is a secret whether you are Concernd in ye work or no. I have reasons to ask this favour.
I should be glad to know whether you are Acquainted with Sr Wm. Yerby that now Possesses the Llaniden Estate in Anglesey after Ld Uxbridge, who bought it in Chancery; My Father & self are Tenants for some of it. I have some merry things to send you as soon as I get to Milford. I am now in a continual hurry.
If Hurry a Chorph Haras will give you leave to write Half a dozen lines to pembroke directed to be left at ye Postoffice for me and (Inclosd) any sort of an Almanack for next year, as you did last year, I'll send you some digrifwch in return, and be very much obligd into ye Bargain.
I've no time to write more at present.
I am Sr Your Most Humble Servt,
Llywelyn Ddu.'
