One of the great technical achievements that revolutionized the idea of time and space, opening a new era in the history of communication, is telegraphy. It is based on the transmission of electrical signals through a cable over long distances, allowing people to communicate instantly. The telegraph spread very quickly and a network of wires stretched around the world.
In 1837, the American painter and physicist Samuel Morse invented the first electromagnetic device for telegraphy, patented in 1840. To send messages by wire, Morse developed in 1838 a simple code of dots and dashes, which represented the letters of the alphabet, known as "Morse code ".
Both Morse code and the telegraph machine were improved over time, with the telegraph becoming the most widespread system of communication and information transmission for more than a century, until the advent of the Internet. The telegraph system consisted of a series of stations repeaters along the transmission line route. Each station had an operator who received and transmitted messages by telegraph. The Morse machine transmitted about 25 words per minute, which were recorded in code on a paper tape. The operator in charge of transmitting the message would decode it and write it on paper using a special typewriter.
In Bessarabia, the telegraph entered in 1860: on April 8, the Bender telegraph station began its activity, and on April 24, the one in Chisinau, following the construction of the first Odesa-Chisinau-Leova telegraph line. Currently, telegraph services have been discontinued. The only ones who still use coded communication are radio amateurs.
The Morse telegraph machine shown comes from the Osinoostrovsky electrotechnical plant, Soviet Union, and dates back to 1934. The exhibit was restored by Mihail Culașco.
The military fortification from Semeni village: „Petru cel Mare’s table”
Tyragetia, serie nouă, vol. III [XVIII], nr. 2, Istorie. Muzeologie
The author tries to find a proper answer for the question of the late military entrenchment situated on the bank of river Prut, on the North of Semeni village (Ungheni).
According to some historians statements, it represents so called „table” where took place the meeting of the Moldovian reigning D. Cantemir and Russian tzar Petru the Great in 1711 summer, during the well-known Prut Campaign.
Such opinion as this one was wrongly and exageratly exploited in the soviet time in order to give rise to some ideological assumptions.
Beginning with 2001, the subject was brought again into attention, focusing on the idea of installing a monument in that place.
Continuing to investigate and to consult the historical sources of that time, the author makes the conclusion that the meeting place of the two dignitaries was the old settlement Tutora, but the origins of the entrenchment in Semeni could have totally others work circumstances, frequently present in the region in the XVII-XVIII centuries.
