This book is about exploring old gold and silver mines in Part One. Part Two is about actual experiences using various recovery equipment to find gold. Part Three is a look at some of the million dollar gold mines from present to the 1800's. Part Four is about new equipment to recover gold from rivers and streams.

Fresh water has become scarce and will become even more so in the coming years, as continued population growth places ever greater demands on the supply of fresh water. At the same time, options for increasing that supply look to be ever more limited. No longer can we rely on technological solutions to meet growing demand. What we need is better management of the available water supply to ensure it goes further toward meeting basic human needs. But better management requires that we both understand the history underlying our current water regulation regime and think seriously about what changes to the law could be beneficial. For Golden Rules, Mark Kanazawa draws on previously untapped historical sources to trace the emergence of the current framework for resolving water-rights issues to California in the 1850s, when Gold Rush miners flooded the newly formed state. The need to circumscribe water use on private property in support of broader societal objectives brought to light a number of fundamental issues about how water rights ought to be defined and enforced through a system of laws. Many of these issues reverberate in today’s contentious debates about the relative merits of government and market regulation. By understanding how these laws developed across California’s mining camps and common-law courts, we can also gain a better sense of the challenges associated with adopting new property-rights regimes in the twenty-first century.

The first full account of the government-sanctioned genocide of California Indians under United States rule Between 1846 and 1873, California's Indian population plunged from perhaps 150,000 to 30,000. Benjamin Madley is the first historian to uncover the full extent of the slaughter, the involvement of state and federal officials, the taxpayer dollars that supported the violence, indigenous resistance, who did the killing, and why the killings ended. This deeply researched book is a comprehensive and chilling history of an American genocide. Madley describes pre-contact California and precursors to the genocide before explaining how the Gold Rush stirred vigilante violence against California Indians. He narrates the rise of a state-sanctioned killing machine and the broad societal, judicial, and political support for genocide. Many participated: vigilantes, volunteer state militiamen, U.S. Army soldiers, U.S. congressmen, California governors, and others. The state and federal governments spent at least $1,700,000 on campaigns against California Indians. Besides evaluating government officials' culpability, Madley considers why the slaughter constituted genocide and how other possible genocides within and beyond the Americas might be investigated using the methods presented in this groundbreaking book.
