Shire Post - I remember those!
Never knew he made any from Eregion though - sorry to have missed 'em.
If there's any mention at all of them, they'd have to be in some of the ancillary material. Silmarillion, Lost Tales, or the like. Eregion was old and gone by LOTR/Hobbit times.
For a translation, I think your best bet is one of the elvish language fora.
