It is quite an easy matter to produce artificial light by burning any combustible substance; we have only to start the chemical combinations which we call combustion, and the conflagration will proceed on its own account. Indeed, we know the great difficulty of stopping a fire as long as it can get at plenty of combustible material. A single match might set enormous forests on fire.

Even when the spark was produced successfully, and the tinder ignited, there was no flame. The smouldering rag had to be carefully nursed until a brimstone match was lighted by it.
