This book on Field Testing For Gold and Silver is a practical manual for prospectors and miners was first published in 1911. The object of this little book is to demonstrate, in the most practical manner possible, how field tests can be made for gold and silver with exceedingly cheap and portable apparatus, and that tests so to obtained are equal to, and may even be made superior to, the ordinary assay as conducted in the laboratory, with its expensive and stationary appliances. To meet the demand for the practical, the procedure suggested in each class of test is decribed in detail, and tables of the apparatus and ingredients necessary are given under their respective numbers, the numbers in the case of apparatus being also applied to the illustrations of the same. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
