—Quæ censet amiculus, ut si

Cæcus iter monstrare velit

—Hor.

Though strength of genius, by experience taught,

Gives thee to sound the depths of human thought,

To trace the various workings of the mind,

And rule the secret springs, that rule mankind;

(Rare gift!) yet, Walpole, wilt thou condescend

To listen, if thy unexperienc'd friend

Can aught of use impart, though void of skill,
