"It will be valuable not only to the prospector, but to the geologist and chem. ist."--Miner, Silver Cliff, Colo.

"It is a complete guide for prospectors and miners, and if its directions are followed some considerable good must necessarily result from its publication."-Record, Canon City, Colo.

"While it does not pretend to contain a full knowledge of geology, mineralogy and metallurgy, yet it does give all that is necessary for the prospector to know; and the book will prove a valuable one to that class of people."--Silver World, Lake City, Colo.'"

"It has not before been our pleasure to read so useful and so carefully prepared a work on all the important questions constantly occurring to the prospector as the little pocket edition written by Mr. Pomeroy. He starts out with the assertion that intelligence is needed in finding, and the blind dependence in the pick is not a safe or profitable mode of discovering mines. There is hardly a point useful to the miner not included in this small book. Tests for gold and silver, character of rock and position of the formation, blowpipe assays, glossary- in fact, it is a full exposition in a convenient form of just what we daily want to know. Mr. Pomeroy has done the country and the business of mining a great service in preparing a work that will tend to make prospecting a study requiring intelligence and care, as should any legitimate business.

The book is at our office for reference any time, though it is hoped that every man who cares to be called a good and faithful miner will purchase a copy for himself. It will repay careful and daily study; in fact, to be without it will be a confession of blind confidence in your own ignorance."-- Bonanza, Gothic, Colo.

"Every miner and prospector should have one of these books, as they tell how to locate, relocate, and work claims. All mining laws are embodied in this book, making it valuable."-- Miner, Prescott, Arizona.

"It is a very useful work for the searcher after precious metals, and will materially aid him in prospecting and locating mines, and should find ready sale in this section."--Arizona Citizen, Tucson, Arizona.

"It is valuable to prospectors and mineral hunters. It shows in what formation the different classes of mineral can be found, and how to seek for the precious deposits. Not only to the prospectors but to the more pretentious scientists can this work become valuable. It treats of geology, mineralogy, chemistry and metallurgy, and describes true fissure veins. An annotation of the mining laws of the United States, and State and Land Office Rules are also added. Every prospector and mining operator should have a copy."--Nugget, Tombstone, Arizona.

"There can be found much that will interest and prove instructive to the miner. It devotes considerable space to geology, mineralogy, chemistry, metallurgy, and good sound advice to any one starting on a prospecting trip. Besides this it contains the mining laws, and much other valuable information."--Demoocrat, Santa Fe, New Mexico.

"The book tells how and where to find gold and silver mines, and how to make chemical_tests and blowpipe assays of any substance conceived to be an ore."-- Golden Era, White Oaks, N. M.

"It is a valuable book, containing much useful matter that we never before saw compiled."--Madisonian, Virginia City, Montana.

"It contains a fund of useful information for the miner and prospector, and constitutes a hand book of information that will be found valuable to all persons engaged in mining enterprises."--Mining Journal, Silver City, Ark.

"If you will give us exclusive sale to Utah, Idaho and Montana, we would advertise it in a large way, and try and push sales. GEO. F. PRESCOTT," Salt Lake City Tribune, Utah.

PREFA СЕ.

Mining interests in this country have long attracted considerable attention, and, at the present day,. instead of showing any signs of abating, the interest manifested is greater than ever before.

Men of every age, character and Social condition hurry to the mining districts in search of fortunes, sanguine of success, but wholly unprovided witli "the" means of attaining it; without any knowledge of mining enterprise without any guide or assistance from the experience of others trusting only in their own judgment, which is in these matters entirely uneducated and practically worthless, or in luck, as much a superstitious fancy in this business as in any other.

Any business, to be successful, requires special knowledge and skill, and this is peculiarly true of mining, since it is based upon a correct understanding of several of the most difficult of the sci

ences.

Fortunes have been wasted in the senseless search for mineral veins in places where they could not by any possibility exist, and many valuable mines have brought nothing to their discoverers because they did not know how to make good use of their property after they had found it.

A thorough knowledge of geology, mineralogy, metallurgy and chemistry would require a long course of study; but as very much of these is not important to the prospector or miner, it is proposed in this small volume to bring together in a convenient shape so much of them as is directly valuable to him, that he may have an opportunity of learning to recognize the metalliferous rocks, the precious ores and their simple tests and assays, as well as their (vi)
