I have formerly said in this epistle, that I could distinguish your writings from those of any others; it is now time to clear myself from any imputation of self-conceit on that subject. I assume not to myself any particular lights in this discovery; they are such only as are obvious to every man of sense and judgment, who loves poetry, and understands it. Your thoughts are always so remote from the common way of thinking, that they are, as I may say, of another species, than the conceptions of other poets; yet you go not out of nature for any of them. Gold is never bred upon the surface of the ground, but lies so hidden, and so deep, that the mines of it are seldom found; but the force of waters casts it out from the bowels of mountains, and exposes it amongst the sands of rivers; giving us of her bounty, what we could not hope for by our search. This success attends your lordship's thoughts, which would look like chance, if it were not perpetual, and always of the same tenor. If I grant that there is care in it, it is such a care as would be ineffectual and fruitless in other men. It is the _curiosa felicitas_ which Petronius ascribes to Horace in his Odes. We have not wherewithal to imagine so strongly, so justly, and so pleasantly; in short, if we have the same knowledge, we cannot draw out of it the same quintessence; we cannot give it such a turn, such a propriety, and such a beauty; something is deficient in the manner, or the words, but more in the nobleness of our conception. Yet when you have finished all, and it appears in its full lustre, when the diamond is not only found, but the roughness smoothed, when it is cut into a form, and set in gold, then we cannot but acknowledge, that it is the perfect work of art and nature; and every one will be so vain, to think he himself could have performed the like, until he attempts it. It is just the description that Horace makes of such a finished piece: it appears so easy, ----_Ut sibi quivis Speret idem, sudet multum, frustraque laboret, Ausus idem._
