will never burn, but they will do to sell to the unwary maid-of-all-work. About twenty years ago Chemistry discovered that the tinder-box might be abolished. But Chemistry set about its function with especial reference to the wants and the means of the rich few. In the same way the first printed books were designed to have a great resemblance to manuscripts, and those of the wealthy class were alone looked to as the purchasers of the skillful imitations. The first chemical light producer was a complex and ornamental casket, sold at a guinea. In a year or so, there were pretty portable cases of a phial and matches, which enthusiastic young housekeepers regarded as the cheapest of all treasures at five shillings. By-and-by the light-box was sold as low as a shilling. The fire revolution was slowly approaching. The old dynasty of the tinder-box maintained its predominance for a short while in kitchen and garret, in farm-house and cottage. At length some bold adventurer saw that the new chemical discovery might be employed for the production of a large article of trade--that matches, in themselves the vehicles of fire without aid of spark and tinder, might be manufactured upon the factory system--that the humblest in the land might have a new and indispensable comfort at the very lowest rate of cheapness. When Chemistry saw that phosphorus, having an affinity for oxygen at the lowest temperature, would ignite upon slight friction, and so ignited would ignite sulphur, which required a much higher temperature to become inflammable, thus making the phosphorus do the work of the old tinder with far greater certainty; or when Chemistry found that chlorate of potash by slight friction might be exploded so as to produce combustion, and might be safely used in the same combination--a blessing was bestowed upon society that can scarcely be measured by those who have had no former knowledge of the miseries and privations of the tinder-box. The Penny Box of Lucifers, or Congreves, or by whatever name called, is a real triumph of Science, and an advance in civilization. Let us now look somewhat closely and practically into the manufacture of a Lucifer Match.
