1848   Mexico ratifies the Treaty of Guadalupe Hidalgo acknowledging the acquisition of Texas and New Mexico by the United States, which included a small portion of Wyoming, via Texas.

1846  resident Polk approved an act that provided for a line of military posts along the Oregon Trail.  In some ways, this has to be regarded as a major development in the history of the United States and the U.S. Army, as the expansion of the Army on to the Western Frontier dominated much of its character for the next century, even continuing to have an influence into its nature well after the Frontier had closed.  Attribution:  On This Day.

1866  Colonel Carrington left Fort Kearny for Fort Laramie where he received instructions from General Pope to name two new outpost along Bozeman Road Fort Philip Kearny and Fort C.F. Smith.  The widely spaced forts were to form more northerly bastions to guard the Bozeman Trail, the southernmost post, Ft. Reno, having already been established during the Civil War by Patrick Connor.  Carrington was one of a group of officers who remained in the Army following the Civil War when Congress established the policy of making room for some wartime officers who had not come from pre war military service or West Point.  Alfred Terry was another, with both men having been lawyers prior to the Civil War.  Attribution:  On This Day.

1869  Territorial government was formally in effect.  Territorial Supreme Court took the oath of office.

1871  Robert H. Milroy takes office as U.S. Marshall.

1887  Sheridan Post established.

1902  The first Carnegie Library in the United States, the Laramie County Library, opened.  Attribution:  Wyoming State Historical Society.

1915  Dr. Amos Barber, Wyoming's second governor after statehood, whose governorship was marred by the Johnson County War and his general ineffective reaction to it, died.  Barber had a successful career as an Army surgeon before entering private practice, and he followed up on that with service again during the Spanish American War, but his having participated through acts of omission in the large cattleman's invasion of central Wyoming is principally what he is remembered for.

1919  May 19, 1919. Laramie to get a refinery, Daniels comes home, Ataturk in Samsun

Big news in Wyoming, and most particularly in Laramie, was that the Midwest Oil Company, which was very active in Natrona County, had determined to build a refinery in Laramie.

People in Laramie today may be surprised to know that this was even considered, let alone that it was actually built, which it was later that year, although the remnants of the refinery remain there.  Indeed, oddly enough, discussion has been going on for several years on how to clean the remnants of the refinery up, a project that has been ongoing, and on May 5 of this present year a legal notice regarding the final work on it was published.

The refinery operated from 1919 to 1932, making it a plant that closed during the height of the Great Depression.  The same location was later operated for a few years as a Yttrium plant, although most of the refining equipment had been removed in the 1930s.  Clean up of the site is nearly complete.
