Baltimore–Washington Telegraph Line
The Baltimore–Washington telegraph line was the first long-distance telegraph system set up to run overland in the United States. Building of line In March 1843, the US Congress appropriated to Samuel Morse to lay a telegraph line between Washington, D.C. and Baltimore, Maryland, along the right-of-way of the Baltimore and Ohio Railroad. Morse originally decided to lay the wire underground, asking Ezra Cornell to lay the line using a special cable-laying plow that Cornell had developed. Wire began to be laid in Baltimore on October 21, 1843. Cornell's plow was pulled by eight mules, and cut a ditch wide and deep, laid a pipe with the wires, and reburied the pipe, in an integrated operation.Dilts, James DThe Great Road pp. 295–96 (1993) However, the project was stopped after about of wire was laid because the line was failing. Morse learned that Cooke and Wheatstone were using poles for their lines in England and decided to follow their lead. Installation of the lines and ...

The First Telegram
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pr ...

First Transcontinental Telegraph
The first transcontinental telegraph (completed October 24, 1861) was a line that connected the existing telegraph network in the eastern United States to a small network in California, by means of a link between Omaha, Nebraska and Carson City, Nevada, via Salt Lake City. It was a milestone in electrical engineering and in the formation of the United States of America. It served as the only method of near-instantaneous communication between the east and west coasts during the 1860s. For comparison, in 1841, the news of the death of President William Henry Harrison had taken 110 days to reach Los Angeles. Background After the development of efficient telegraph systems in the 1830s, their use saw almost explosive growth in the 1840s. Samuel Morse's first experimental line between Washington, D.C. and Baltimore—the Baltimore-Washington telegraph line—was demonstrated on May 24, 1844. By 1850 there were lines covering most of the eastern states, and a separate network o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Book Of Numbers
The book of Numbers (from Greek Ἀριθμοί, ''Arithmoi''; he, בְּמִדְבַּר, ''Bəmīḏbar'', "In the desert f) is the fourth book of the Hebrew Bible, and the fourth of five books of the Jewish Torah. The book has a long and complex history; its final form is possibly due to a Priestly redaction (i.e., editing) of a Yahwistic source made some time in the early Persian period (5th century BC). The name of the book comes from the two censuses taken of the Israelites. Numbers begins at Mount Sinai, where the Israelites have received their laws and covenant from God and God has taken up residence among them in the sanctuary. The task before them is to take possession of the Promised Land. The people are counted and preparations are made for resuming their march. The Israelites begin the journey, but they "grumble" at the hardships along the way, and about the authority of Moses and Aaron. For these acts, God destroys approximately 15,000 of them through vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alfred Vail
Alfred Lewis Vail (September 25, 1807 – January 18, 1859) was an American machinist and inventor. Along with Samuel Morse, Vail was central in developing and commercializing American telegraphy between 1837 and 1844. Vail and Morse were the first two telegraph operators on Morse's first experimental line between Washington, D.C., and Baltimore, and Vail took charge of building and managing several early telegraph lines between 1845 and 1848. He was also responsible for several technical innovations of Morse's system, particularly the sending key and improved recording registers and relay magnets. Vail left the telegraph industry in 1848 because he believed that the managers of Morse's lines did not fully value his contributions. His last assignment, superintendent of the Washington and New Orleans Telegraph Company, paid him only $900 a year, leading Vail to write to Morse, : "I have made up my mind to leave the Telegraph to take care of itself, since it cannot take car ...

B&O Railroad Museum
The B&O Railroad Museum is a museum and historic railway station exhibiting historic railroad equipment in Baltimore, Maryland. The Baltimore and Ohio Railroad (B&O) company originally opened the museum on July 4, 1953, with the name of the Baltimore & Ohio Transportation Museum.
