Excerpt from Practical Instructions: In the Search for and the Determination of the Useful Minerals, Including the Rare Ores; For the Prospector, Miner, and as a Ready Reference for Everybody Interested in the Mineral Industry

IT is the aim of this little book to furnish severely simple, but fully dependable, means by which any one can determine the useful minerals.

The few apparatus required can be made at the mere cost of thirty minutes' labor. Any druggist can supply the few inexpensive chemicals necessary. The whole outfit need not weigh a pound.

Absolutely no skill is required to carry cut any of the tests. Many of the tests are gorgeously simple. The following are a few instances taken at random: A match ﬂame positively identifies a very important metal. A burning pine sliver de termines a leading ore of silver. A live coal serves to identify each one of two valuable minerals which are physically similar. Half a dozen taps of the hammer assign certain ores to the class to which they belong.

Minerals which are similar in appearance are differentiated one from the other by some striking characteristic.

Simple tests are given by which the rare ores may be readily recognized.
