There was another _bit-karê_, which had a very different meaning and was used for a very different purpose. This was “the House of Cereals,” the storehouse or barn in which were stored such tithes of the temples as were paid in grain. The name is also sometimes applied to the _sutumme_, or royal storehouses, where the grain and dates collected by the tax-gatherers were deposited, and from which the army and the civil servants were provided with food. The superintendent of these storehouses was an important personage; he was the paymaster of the state officials, in so far as they received their salaries in kind, and the loyalty of the standing army could be trusted only so long as it could be fed. Similar storehouses existed in Egypt, from the age of the eighteenth dynasty downward, and it is probable that the adoption of them was due to Babylonian influence. They gave the King a powerful hold upon his subjects, by enabling him to supply them with grain in the years of scarcity, or to withhold it except upon such terms as he chose to make with them. The exportation of the grain, moreover, was a yearly source of wealth and revenue which flowed into the royal exchequer. In Babylonia, as in Egypt, the controller of the granaries was master of the destinies of the people. CHAPTER X. LETTER-WRITING We are apt to look upon letter-writing as a modern invention, some of us, perhaps, as a modern plague. But as a matter of fact it is an invention almost as old as civilization itself. As soon as man began to invent characters by means of which he could communicate his thoughts to others, he began to use them for holding intercourse with his absent friends. They took the place of the oral message, which was neither so confidential nor so safe. Classical scholars have long been familiar with the fact that letter-writing was one of the accomplishments of an educated Greek and Roman. The letters of Cicero and Pliny are famous, and the letters of Plato and Aristotle have been studied by a select few. Even Homer, who seems to avoid all reference to the art of writing as if it were an unclean thing, tells us of “the baleful characters” written on folded tablets, and sent by Prœtos to the King of Lycia. Criticism, it is true, not so long ago doubted the facts of the story and tried to resolve the characters and the tablets into a child’s drawings on the slate. But archæology has come to the rescue of Prœtos, and while we now know that letters passed freely backward and forward in the world in which he is supposed to have moved, Mr. Arthur Evans has discovered the very symbols which he is likely to have used. Even the Lycians, to whom the letter was sent, have been found, not only on the Egyptian monuments, but also in the tablets of Tel-el-Amarna.
