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.
Deposit of Flint Raw Material from the Late Tripolian Settlement Sharin III
Tyragetia, serie nouă, vol. IV [XIX], nr. 1, Arheologie. Istorie Antică
This article is dedicated to the deposit of the flint blades, found in the settlement of the latest period of development of the Tripolian culture (C II) Sharin III (v. Sharin, Uman’ district, Cherkassy region, Ukraine). Regarding the analogous deposits (Halep’ye, Sandraky, Ivano-Frankovsk, Kosenovka) from the Southern Bug and Dnieper and the Southern Bug and middle Dnestr rivers, we may consider them as deposits of raw material. Taking into account the location of the deposits (near buildings), value and prestige of the high quality flint from Volynia, this deposits can be connected with rituals. Further, the depositions were the part of a ritual of «leaving the settlements».
List of illustrations: Table 1. The results of the radiocarbon dating of the remains of building (№ 2), were the Sharin deposit was found. Fig. 1. Location of the deposits of flint raw material and workshops in the area of Tripolian culture (period C II): 1 - Sharin; 2 - Kosenovka; 3 - Halep’ye; 4 - Sandraky; 5 - Ivano-Frankovsk; 6 - Kislitskoe 7 - Bodaki.
