That the postal system cannot have been very much developed, is clear from the means adopted to announce the New Moon in various localities. This official announcement certainly necessitated a complete system of communication. At first, we are told (_Rosh ha-Shanah_, ii, 2), fires were lighted on the tops of the mountains; but the Samaritans seem to have ignited the beacons at the wrong time, so as to deceive the Jews. It was, therefore, decided to communicate the news by messenger. The mountain-fires were prepared as follows: Long staves of cedar-wood, canes, and branches of the olive-tree were tied up with coarse threads or flax; these were lighted as torches, and men on the hills waved the brands to and fro, upward and downward, until the signal was repeated on the next hill, and so forth. When messengers were substituted for these fire signals, it does not appear that they carried letters; they brought verbal messages, which they seem to have shouted out without necessarily dismounting from the animals they rode. Messages were not sent every month, but only six times a year; and a curious light is thrown on the means of communication of the time, by the legal decision that anyone was to be believed on the subject, and that the word of a passing merchant who said that "he had heard the New Moon proclaimed," was to be accepted unhesitatingly. Nowadays, busy men are sometimes put out by postal vagaries, but they hardly suffer to the extent of having to fast two days. This calamity is recorded, however, in the Jerusalem Talmud, as having, on a certain occasion, resulted from the delay in the arrival of the messengers announcing the New Moon.
