Bunker Hill Bridge is the only surviving Haupt truss bridge in the U.S. and one of only two surviving covered bridges in North Carolina. Patented in 1839, the Haupt truss featured diagonal braces spanning multiple panels, which was an attempt to eliminate the cross-strain found in lattice truss bridges. Although it was almost immediately eclipsed by the Howe truss and never reached the mainstream of covered bridge building, the Haupt truss is of interest for its association with Gen.

The first authenticated discovery of gold in the U.S. occurred on the Cabarrus County farm of John Reed in 1799, sparking the nation's first gold rush. During its peak years, more than a million dollars of gold was recovered a year, making North Carolina a leader in gold production until 1848. This mill, built by the Mecklenburg Iron Works of Charlotte, North Carolina, is original except for the timber work. Two groups of five 750-pound stamps with 5- to 7-inch lift, rose and fell thirty-five times a minute to yield a finely crushed ore.

When the Adams Plant went into operation on August 26, 1895, it represented a key victory for alternating-current systems over direct-current. The clear advantage of high voltage AC for long distance power transmission and the unprecedented size of the plant (it reached its full capacity of ten 5,000-HP generators in May 1900) influenced the future of the electrical industry worldwide.
In August 1895 the Adams No. 1 generating station of the Niagara Falls Power Company first supplied electric power to local industries in Niagara Falls, New York.

This 350-horsepower Corliss type steam engine is an example of a typical late nineteenth century steam engine. The essential feature of Corliss type engines is the valves that admit steam to and exhaust it from the cylinder. The Corliss valve gear made the engine extremely efficient in steam consumption and was the most efficient system for controlling low to medium speed engines.
This particular engine operated for more than eighty years, having been retired not by age but over concern for stack emissions by the U.S. Environmental Protection Agency. The engine was built by the William A.

The historic Folsom Power House #1 marks one of the first successful uses of hydroelectric power in the world and the first successful transmission of power long distance (twenty-two miles to Sacramento). The old Folsom Power House still shelters the machinery generated to drive streetcars and illuminate the city of Sacramento.
In his laboratory at Western Reserve University (Now Case Western Reserve University), Edward W. Morley carried out his research on the atomic weight of oxygen that provided a new standard to the science of chemistry. The accuracy of his analyses has never been superseded by chemical means. His great work, published in 1895, also gave important insight into the atomic theory of matter.
He observed, after carefully analysis of the volume proportions in which hydrogen and oxygen unite, that the atomic weight of oxygen was 15.879.
The plaque commemorating the event reads:
