Potosi, Wisconsin
Potosi is a village in Grant County, Wisconsin, United States. The population was 646 at the 2020 census. The village is in the Town of Potosi. History Potosi is located where Wisconsin's lead ore belt intersects with the Mississippi. The post office (1837 to present) was originally located between Van Buren and Head of the Hollow, then at Van Buren, then at La Fayette. In 1839, the leaders of three settlements (Snake Hollow, sometimes called Head of the Hollow, Van Buren, and La Fayette) decided to combine the villages. The new, larger community was named Potosi, and the post office moved one last time, to the center of the new, merged community. There are several explanations for the origin of the name Potosi, but the correct one is unknown. Many mining towns are named Potosi, ultimately derived from the fabled silver mines of Potosí, Bolivia. Another explanation is that Potosi was named for Potosi, Missouri, where a lot of the early lead miners originated. Another expla ...

Brief history In 1866, the United States Army Corps of Engineers established the U.S. Army Engineer School, Engineer School of Application at Fort Totten (Queens), Willets Point, New York. The first commander of this school, Major Henry Larcom Abbot, was almost single-handedly responsible for designing and supervising the program of research and development that defined the strategy and tactics for the mine defense of American harbors. Abbot experimented with underwater explosives, fuzes, cabling, and electrical equipment for over a decade before publishing the first manuals on the use of mines in coast defense in 1876–77. At least one experimental controlled minefield was emplaced at this time, at Fort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Potosi, Wisconsin
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inland Waterways Commission
The Inland Waterways Commission was a United States federal agency, created by Congress in March 1907 at the request of President Theodore Roosevelt, to investigate the transportation crisis that recently had affected the nation's ability to move its produce and industrial production efficiently. The immediate crisis centered on insufficient railroad capacity developed by the private sector, and competing but neglected inland shipping, the navigation of which had been deemed under federal purview since 1824. The temporary commission lasted until the end of Roosevelt's presidency, but his conservationist progressive interest was focused more than on transportation alone.
