To spill, should breakage follow your advice!
Head-break to him will be heart-break to you
For having preached "Disturb no ruins here!
Are not they crumbling of their own accord?
Meantime, let poets, painters keep a prize!
Beside, a sage pedestrian picks his way."
A sage pedestrian—such as you and I!
What if there trip, in merry carelessness,
And come to grief, a weak and foolish child?
Be cautious how you counsel climbing, then!
