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.

In the given study one has brought into discussion the problem of fair trade evolution only in the south of Basarabia, in the town-ports Ismail, Reni and Chilia, in the first half of the 19th century. The fairs were organised twice a year – in autumn and spring, before the sowing and after the harvesting. These fairs were known as being manufactured, especially those from Ismail, which respectively had also a greater commercial circuit, a situation favoured by the territorial-administrative statute of the specific town, as well as river – ways much easier of access and more practical towards the port of Ismail. Along with the goods of import, of which the main role was played by those made of flax, hemp, wool, cotton and silk, within the fairs were also sold local goods, most of them agro-food ones - cereal, wine, honey, salt etc. The fairs from the towns Reni and Chilia attracted not only local tradesmen, but also foreign ones, from the Russian internal provinces and abroad.
The fair trade in the south of Basarabia, in the period under discussion, was influenced by the harvests volume, the growth in number of the markets and shops, the Russian commercial and custom-house policy, as well as the plague in year 1848 and in year 1855 and the war in Crimeea.
