From the book's Preface:

In preparing this little work the author has felt the difficulty
which arises in a theoretical disseration on so eminently
practical a subject as prospecting.It seems like giving rules
and prescriptions for hunting or fishing or any other natural
or practical pursuit.Though theory and practice are not at
variance when happily combined, yet either without the other
proves very unsatisfactory.Thus, the reader without the
other proves very unsatisfactory.Thus, the reader of this
book, should he start out armed only with its theory, will
find himself for some time pretty much "at sea" when he
comes to actual practice in the field.As, however, he grad-
ually obtains some practical experience, he may find this little
work of use to him.So, also, the seasoned prospector, who
has hitherto to trusted to luck, keenness of observation,
intuition and experience, may find himself in the future much
better equipped by acquiring a little of the theory.

Whilst we have endeavored ta give the prospector all
assistance in our power, as to the best means of educating
himself, describing his outfit, etc., we have devoted special
attention to the description of such geological and other phe-
nomena as he is likely to meet with in connection with his
work, so that he may have an intelligent idea of them when
he encounters them.

We have selected just as much material as we think would
be most interesting and useful to him, saving him the time
and trouble of wading through heavy tomes and laboriously
picking out from a vast amount of, for his purpose, super-
fluous matter, that which he will most require.

The work is intended to be a popular one, addressed to-
the average student, prospector and miner and to the
general public. The illustrations are largely drawn by the
author from Colorado mines and Rocky Mountain subjects
which are most familiar to him.

This is a book which views and presents the gold and other precious metal extractions from a new wider angle, extending to include both the Earth and the metallurgical sciences. Some of the topics are: - Gold and silver mineral occurrences in their ores; - Photomicrographs of refractory and amenable mineral/ores; - How irregular gold and silver distributions may be used for the efficient planning of the extraction process; - Microanalytical techniques; - Descriptions or uranium and many base metals for comparison. The book is written for a broad audience, from the manager of operations to the metallurgist, field geologist and other earth scientists, to the professor and student alike. ... Read more

Product Description
Take a trip back in time, to the days of old, to the days of gold, to the days of '49. "The California Gold Country: Highway 49 Revisted" will take the reader on a trip through California's Gold Rush Country, stopping at mining camps and historic sites along Highway 49, The Golden Chain Highway. 266 full-color photos easily identify the old buildings and sites that date back to the 1850's. A history of each mining camp still around for visitors to see today is included, relating how the camp was discovered, its early settlers, and interesting stories. Brief biographies of such famous Gold Rush-era citizens as John Sutter, James Marshall and Black Bart are also included. An excellent resource for students interested in the California Gold Rush, don't forget to take it along on your next trip to the Gold Country. In a peaceful, gentle valley surrounded by fine stands of tall timber, James W. Marshall served as the construction superintendent of a sawmill being built for Captain John Sutter. As work on the mill neared completion, it was found that the water flowing through the tailrace was backing up, which prevented the waterwheel from turning properly. To solve this problem the tailrace had to be deepened to increase the flow of water and thereby create a stronger force to turn the wheel.

With the men working on deepening and widening the race during the day, it became Marshall's custom to raise the gate every evening to let the water wash out as much sand and gravel through the night as possible; in the morning, while the men were getting breakfast, he would walk down, shut off the water, and look along the race to see if any further work needed to be done. It was on one such morning that Marshall reached into history by picking up a few glittering flakes of gold, uncovered by the digging of the race and the action of the water, which wa shed away the rocks, gravel and sand, and left the gold.

Returning quickly to the mill, Marshall shouted to the men, "Boys, by God I believe I have found a gold mine!" And even after they tested the material--it was bitten, hammered, compared to a $5 gold piece, and boiled in lye--some still expressed their disbelief. Whereupon Marshall firmly replied, "I know it to be nothing else." ... Read more
