If cloth'd in black you tread the busy town,
Or if distinguish'd by the reverend gown,
Three trades avoid: oft in the mingling press
The barber's apron soils the sable dress;
Shun the perfumer's touch with cautious eye,
Nor let the baker's step advance too nigh.
Ye walkers too, that youthful colours wear,
Three sullying trades avoid with equal care:
The little chimney-sweeper skulks along,
And marks with sooty stains the heedless throng;
