“ So in a modern city if all the gas were turned off simultaneously at all the burners but one, the flame would no doubt blaze at that one burner with a fierceness such as no single burner could shew when all are burning at the same time. The analogy may help us to understand the process of reasoning which leads the peasantry to insist on the extinction of all common fires when the need-fire is about to be kindled. ”
