Map of Bolivia, Showing Forest and Agriculture Areas, and Mineral Localities
This 1912 map shows the agricultural, forest, and mineral wealth of Bolivia. Mineral production is shown as located mainly in the western part of the country, in or near the Andes Mountains. The locations of mines producing antimony, bismuth, copper, gold, lead, silver, wolfram, and tin, Bolivia’s most important mineral product, are indicated. Tin was mined in the departments of Cochabamba, La Paz, Oruro, and Potosí. Production boomed in the late-19th century–early 20th century, as the extension of the rail line to Oruro made possible the export of ...
An Account of a Voyage up the River de la Plata, and Thence over Land to Peru: With Observations on the Inhabitants, as Well as Indians and Spaniards, the Cities, Commerce, Fertility, and Riches of That Part of America
Acarete du Biscay was a Frenchman, possibly of Basque origin, about whom very little is known. In December 1657 he embarked from Cádiz, Spain for the Plate River region of South America, posing as the nephew of a Spanish gentleman to circumvent a ban by Spain on visits by foreigners to its New World possessions. In 1658 he traveled overland across the Argentine pampas to the silver mines of Potosí, located in present-day Bolivia. In 1672, Acarete published an account of this trip in his native French. A later version ...
Porkknocker Ready for his Journey Across the Mountains, on his Back is a Warishi
This photograph shows a man on the savannahs of Guyana, carrying his equipment and belongings in a warashi (a knapsack-like basket) on his back. He appears to be prepared for a trek into the interior of Guyana, in search of gold and diamonds. A porkknocker is a Guyanese prospector and miner who extracts and processes gold and diamonds using simple methods. These rugged individualists have been responsible for some of the great discoveries of gold and diamonds in Guyana's interior. The photograph is from the collection of the Columbus ...
Searching for Diamonds
This photograph shows three porkknockers in the interior of Guyana. A porkknocker is a Guyanese prospector and miner who extracts and processes gold and diamonds using simple methods. These rugged individualists have been responsible for some of the great discoveries of gold and diamonds in Guyana's interior. There are many stories of porkknockers who struck it rich, but then spent their fortunes in ways both tragic and comic. The photograph is from the collection of the Columbus Memorial Library of the Organization of American States (OAS), which includes 45 ...
The Book on the Properties of Precious Gems
The title page identifies this manuscript as a copy of Kitab khawas al-jawāhir (The book on the properties of precious gems), written by Yaqūb ibn Ishāq al-Kindī in the ninth century.

The Blossoms of Thoughts Regarding the Precious Stones
Azhār al-Afkār fī Jawāhir al-Ahjār (The blossoms of thoughts regarding precious stones) is considered the most detailed and complete treatise of the Middle Ages on stones and their properties. Lapidaries, or treatises devoted entirely to the discussion of precious stones and their features, can be traced to ancient Greece. Pliny, in his Naturalis Historia (Natural history), mentions at least 20 authors as sources of his knowledge of stones, even though, of the works he cites, only the treatise On Stones by Theophrastus (circa 371–287 BC) has survived. Theophrastus’s ...

Churchill resigned from the cabinet of Lord Salisbury in December 1886. To recover his health and restore his finances, in 1891 he made a long visit to South Africa, where he hunted, made investments in gold mines, and ...
Africa, with All Its States, Kingdoms, Republics, Regions, Islands, &c
This 1794 map by Solomon Boulton (Bolton) was adapted from one originally published in 1749 by Jean Baptiste Bourguignon d’Anville (1697–1782), the French geographer and cartographer. D’Anville reformed European cartography by rejecting plagiarism and unconfirmed cartography. D’Anville’s maps often had blank spaces in places where earlier maps had been filled with figments of the imagination and features based on hearsay evidence. This map shows gold, silver, and gemstone mines, the hot springs near the settlement of Caledon, and the towns of Stellenbosch and Drakenstein. Also ...
