1830-1839

McCormick was born on the 620-acre farm known historically as “Walnut Grove Farm” in 1809.  He built the first practical grain reaper, which was successfully demonstrated in a field of oats owned by John Steele in nearby Steeles Tavern in 1831.  

The Borden Base Line is a 39,009.73 feet (7.42 miles ) survey line through the State of Massachusetts. The line was the first project of its kind undertaken in America and its establishment was the key element for Massachusetts pioneering mandate to survey the entire state. 

The challenge was to use trigonometrical principles, instead of astronomical observation alone, to provide greater accuracy in surveying large areas.

Opened in 1835, the Thomas Viaduct was the first multiple-arch, stone railroad viaduct in the United States. The viaduct is composed of eight arches each with a clear span of about 58 feet. The viaduct has an overall length of 614 feet and a height of about 60 feet above the Patapsco River. Construction of the viaduct began in August of 1833, and a ceremony marking its completion was conducted on July 4, 1835. The viaduct was constructed for the Baltimore and Ohio (B&O) Railroad and is named in honor Philip E. Thomas, who served from 1827 to 1836 as the first president of the B&O.

The St. Charles Avenue Streetcar Line is the oldest surviving interurban-urban passenger rail transportation system in the United States. Originally incorporated as the New Orleans Carrollton Rail Road in 1833, service began in 1835. A variety of motive power had been used including horses, mules, overhead cable, steam engines, and ammonia engines before electrification in 1893. The 900-series cars presently in service were designed and built by the Perley A. Thomas Car Company of High Point, North Carolina, in 1923 to 1924.

The 50-mile Houston Ship Channel is a manmade port for ocean-going vessels, stretching from the Gulf of Mexico to Houston and Harris County, Texas.   

For more than 174 years, the Canton Viaduct has stood as a dominating structure on the New England landscape. When completed in 1835, the slightly curved, granite masonry bridge - 615 feet long, 70 feet high, and 22 feet wide - carried a single track of the Boston and Providence Railroad, providing a critical link in the establishment of rail service between Boston and New York. In 1860, a second track was added. With few major alterations, the viaduct has continued to provide safe rail transportation to heavier and faster loads throughout the 20th century.

Ithamar A. Beard, an engineer of some prominence in New England, surveyed the mill brook and selected the best site for a storage dam. Contractor Simeon Cobb, knowledgeable of contemporary civil engineering practices, made major changes to the dam's original design, converting the linear dam into a gentle arch.

Built with a single set of tracks consisting of hardwood rails and wooden ties, and using wooden trestles to carry it over low-lying areas, the 136-mile Charleston-Hamburg Railroad was one of the longest railroads in the world when it was completed in 1833. It also became the first railroad in the United States to be powered entirely by steam, the first to carry mail under contract, and the first to provide regularly scheduled passenger service.
