Talk with prudence to a Beggar — The Count of Monte Cristo

Talk with prudence to a Beggar 1
Of "Potose," and the mines!
Reverently, to the Hungry
Of your viands, and your wines!

Cautious, hint to any Captive 5
You have passed enfranchised feet!
Anecdotes of air in Dungeons
Have sometimes proved deadly sweet!
(F.118/J.119)
[1–6] Talk, a Beggar:: the meeting of Edmond Dantes and Abbe Faria.
[7] Dungeons:: Edmond and Faria were in dungeon, not ordinary cells.
[8] air, Dungeons, sweet:: for Edmond, it was a sweet because he had knowledge there and later treasure.
