Unheeding each small street-boy elf

Who tauntingly cries, “clean thyself!”

Mild Dustman! in thy filthy face

A moral he who looks may trace,—

A moral which, perchance, hath struck

Thyself, when ’neath thy weight of muck;

For, to my fancy, in thine eye

A quaint philosophy doth lie,

Which says, “who dirt from others sweeps

More dirt upon himself but heaps!”
