In this short monologue the speaker points out a distinctive feature of New York City – steam or “fumo” that regularly erupts from manhole covers. He explains that the phenomenon is caused by a massive, city‑wide steam heating system that runs beneath Manhattan. The system transports high‑pressure water vapor for heating and other purposes, and the steam is released through the manhole grates as a safety vent. The speaker mentions that a knowledgeable tour guide clarified this for him, emphasizing that the visible steam is simply the venting of the underground high‑pressure steam network.
