I want to know the answer to the following question:
In addition to cannon fire, what did Franklin suggest to act as Parisians' alarm clock?
All the background I'm provided with is that "During his time as an American envoy to France, Benjamin Franklin, publisher of the old English proverb, "Early to bed, and early to rise, makes a man healthy, wealthy and wise", anonymously published a letter suggesting that Parisians economize on candles by rising earlier to use morning sunlight.". Is that enough to answer the question?
