But whatever the subject, your exquisite taste
Will ensure a design very charming and chaste,
Like yourself, full of nature and beauty—
Yet besides the good points you already reveal,
You will need a few others—of well-temper'd steel,
And especially form'd for the duty.
For suppose that the tool be imperfectly set,
Over many weak lengths in your line you will fret,
Like a pupil of Walton and Cotton,
Who remains by the brink of the water, agape,
