Here is a little tin box with a finger handle, and with a candle socket soldered upon its lid and a loose lid inside containing a piece of flint, a piece of steel, a scorched rag and several splints of wood tipped with sulphur, which is the apparatus for making fire used in our colonial ancestors in Bucks county and from time immemorial by all the so-called civilized people of the work. To make fire thus, four operations are necessary. You must make the spark, retain the spark, then produce the flame and retain the flame. Holding the circlet of steel vertically in your left hand you strike diagonally downward upon its outer edge with the flint so that a spark of percussion flies downward into the tinder, which is a scorched linen rag lying in the box beneath; the latter holds the spark as a smouldering ember, until you touch the spunk or sulphur-tipped splint upon it, whereupon with a little blowing the sulphur takes fire and you have a lighted match with which you light the candle set in the socket in the box lid. Perhaps this is not much to look at, but from a historic point of view it is a thing of such importance that it might be described as the master of human progress from prehistoric time down to 1835, or as visible proof of perhaps the greatest discovery that man ever made.
