Newbold Plow - cast iron plow by Charles Newbold
The Newbold Plow
The plow evolved from the all-wood designs of antiquity, to the use of iron parts. In 1720, the first English patent for a wooden moldboard sheathed with iron was issued to Joseph Foljambe. From that the evolution to plows made with cast iron moldboards and shares occurred in Scotland in 1785 by James Small. These cast iron plows were then imported to the U.S.
Charles Newbold, born in Chesterfield, NJ (1780), spent his teenage years investigating the use of cast iron to improve on the heavy iron-clad wooden plow then available. He was issued the first US patent for a plow on 26 Jun 1797. The plow was cast as one piece—the moldboard, share, and land-side all cast together—with wooden handles and beam added.

The issue of whether to permit slavery in the territories organized in this new land consumed Congress at the end of the 1840s. During the war, Congressman David Wilmot introduced the Wilmot Proviso, a proposal to ban slavery in any new territory acquired from Mexico. The measure passed in the House of Representatives but failed in the Senate.
Congress was also seeking resolutions for several other controversial matters. Antislavery advocates wanted to end the slave trade in the District of Columbia, while proslavery advocates aimed to strengthen fugitive slave laws. But the most pressing problem was California: the many emigrants who had flocked to the territory upon the discovery of gold in the late 1840s had forced the question of its statehood and status as a slave or free state.
The presidential election of 1848 determined which of these issues would be tackled first.
There would be Major conflict at first but as I understand it would be resolved
