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.

Among Early Paleolith monuments on the territory of Moldova, Bobulești V site prominently ranks in the Răut river basin. It was situated on the surface of the Răut river third terrace between Gura Camencii and Bobulești villages, Florești region. On the surface of the terrace, badly destroyed by yearly floods, over three thousand of flinty objects – Early Paleolith nucleus, chips and tools typical for apprentice monuments of the region have been gathered. Dwellers of the site used Klektonian technique to chip off flint. Typological classification of the Bobulești V tools is made by the method of F. Bordes. Each object is described in order. Hollow and toothed tools, also many rostral shapes (N62) typical for Early Paleolith monuments of this region constitute a remarkable part of the tools.
Immediate analogies of the flint articles of Bobulești V site we find among Early Paleolith monuments Duruitoarea Veche, Mersyna, Ripiceni-Izvor, Luca-Vrubleveckaja which form a group of peoples sites of the Risskaya glaciation’s epoch.
