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 collections of the NMAHM are two medieval treasures similar as regarding their structure. These are the treasures from villages Mârzești and Morozeni, both discovered in the year 1962 in Orhei district during farming works.
The treasures contain each 17 polish coins made of white metal and are framed into the same chronological limits – the years 1501-1506 and the years 1615, 1616. The coins are issued during the reign of Alexandru the 1st (1492/1501- 1506), Sigismund the 3rd the Old (1506-1548), Sigismund the 2nd August (1545/1548-1572) and Sigismund the 3rd Vaza (1587-1632). In both treasures predominate the Lithuanian ½ grosh: 16 ½ grosh from the period of the three consecutive reigns and a dreipolker from Sigismund the 3rd in the treasure from Mârzești and 13 ½ grosh from the same three reigns, 3 1 ½ grosh and a triple grosh from Sigismund the 3rd in the treasure from Morozeni.
We consider useful for researchers the introduction into the scientific circuit of the two coin deposits with the detailed description of the objects.
