Experimental Mine, U.S. Bureau of Mines is a landmark located in the Pittsburgh suburb of Bruceton, Pennsylvania. In 1910, the newly created U.S. Bureau of Mines leased a 38-acre tract of land from the Pittsburgh Coal Company and opened the Experimental Mine. One of the early findings in the Experimental Mine demonstrated that coal dust by itself was capable of propagating an explosion even in the absence of any methane gas. This demonstration was contrary to the old belief widely held at the time that coal dust could not explode without gas. This view had led to the very dangerous and widespread practice of using loose coal dust in mines to pack explosives in boreholes, which had cost many thousands of lives. These early experiments clearly proved that such a practice was too hazardous to continue.

Oliver Miller Homestead
Oliver Miller Homestead

The Oliver Miller Homestead, site of the James Miller House, is a public museum that commemorates pioneer settlers of Western Pennsylvania. It is located in Allegheny County, Pennsylvania's South Park 10 miles (16 km) south of downtown Pittsburgh in South Park Township. The Millers were among the first families in the area when the land was opened for settlement in 1769 - 1770. Oliver Miller died in 1782, a decade before the Whiskey Rebellion, which put the property at the center of early-American history. His son, James Miller, inherited the farm. In 1794, US Marshal David Lennox was led to the home of William Miller, brother of James, by John Neville (who was related to the Millers through marriage) to issue a writ of non-compliance for not registering his still. It came with a steep fine and a summons to Philadelphia. Varying accounts of the event are in agreement that a shot was fired during the confrontation at William Miller's home by someone in the group of men who confronted the marshal. They were probably farmhands working in the field. The eye-witness account states their language was unknown to Lenox and Neville, which might have been a variation of Irish or Scottish. William Miller's homestead was located near the fairway of #7 on the front 9 holes of South Park Golf Course, just up the lane from his brother's property. William was the captain of the local militia, and fate would have it that on the same day, the militia was drilling at Mingo Creek. Word quickly reached the militia about the event that had taken place at William's property which culminated in the assault on Neville's home in the coming days. It was added to the National Register of Historic Places in 1975.
