material for the purpose. That the Torah was not to be written on a vegetable product was an assumed first principle. The Samaritans went so far as to insist that the animal whose hide was needed for so holy a purpose, must be slain Kasher. Similarly with divorce documents. A Get on paper would be held legal _post factum_, though it is not allowed to use that material, as it is easily destroyed or mutilated, and the use of paper for the purpose was confined to the East. Some allowed the Book of Esther to be read from a paper copy; other authorities not only strongly objected to this, but even forbade the reading of the Haftarah from paper. Hence one finds in libraries so many parchment scrolls containing only the Haftarahs. The Hebrew word for letter, Iggereth, is of unknown origin, though it is now commonly taken to be an Assyrian loan-word. It used to be derived from a root signifying to "hire," in reference to the "hired courier," by whom it was despatched. Other terms for letter, such as "book," "roll," explain themselves. Black ink was early used, though it is certain that it was either kept in a solid state, like India ink, or that it was of the consistency of glue, and needed the application of water before it could be used. For pens, the iron stylus, the reed, needle, and quill (though the last was not admitted without a struggle) were the common substitutes at various dates. We must now return to the subject with which we set out, and make a few supplementary remarks with regard to the actual conveyance of letters. In the Talmud (_Baba Mezia,_ 83b) a proverb is quoted to this effect, "He who can read and understand the contents of a letter, may be the deliverer thereof." As a rule, one would prefer that the postman did not read the correspondence he carries, and this difficulty seems to have stood in the way of trusting letters to unknown bearers. To remove this obstacle to free intercourse, Rabbenu Gershom issued his well-known decree, under penalty of excommunication, against anyone who, entrusted with a letter to another, made himself master of its contents. To the present day, in some places, the Jewish writer writes on the outside of his letter, the abbreviation [Hebrew: beth-cheth-daleth-resh-''-gimel], which alludes to this injunction of Rabbenu Gershom. Again, the Sabbath was and still is a difficulty with observant Jews. Rabbi Jose ha-Cohen is mentioned in the Talmud (_Sabbath_, 19a) as deserving of the following compliment. He never allowed a letter of his to get into the hands of a non-Jew, for fear he might carry it on the Sabbath, and strict laws are laid down on the subject. That Christians in modern times entrusted their letters to Jews goes without saying, and even in places where this is not commonly allowed, the non-Jew is employed when the letter contains bad news. Perhaps for this reason Rabbenu Jacob Tarn permitted divorces to be sent by post, though the controversy on the
