In the internal administration of his empire Shar-Gani-sharri appears to have inaugurated, or at any rate to have organized, a regular system of communication between the principal cities and the capital. The references to separate cities, which occur in the contemporary inscriptions of his reign, are not numerous. From the texts found at Nippur, we know that he rebuilt E-kur, the great temple of Enlil, and many of the bricks which formed his temple-platform and that of Narâm-Sin have been found in place.[56] The mace-head from Abû Habba[57] is an indication that, like his predecessors on the throne of Kish, he devoted himself to enriching the great temple of the Sun-god in Northern Babylonia; while one of his date-formulæ supports the tradition of his building activity in Babylon.[58] But such votive texts and records throw no light upon his methods of government, or upon the means he took to retain his hold upon the more outlying districts of his empire. Some striking evidence upon this point has, however, been recovered at Tello, and this is furnished, not by any formal record or carefully inscribed monument, but by some rough lumps of clay, which had been broken and thrown on one side as useless _débris_ during the reigns of Shar-Gani-sharri himself and his successor. Along with the dated tablets of this period there were found at Tello, in a mound to the S.S.E. of the "Tell of Tablets," a number of sun-dried lumps of clay, most of them broken in pieces, but bearing traces of seal-impressions upon their upper surface.[59] A careful comparison and examination of them showed that on their under sides impressions of cords and knots were still visible, and it was evident that the clay had been used for sealing bales or bundles of objects, which had been tied up and secured with cords. Some of the seal-impressions bear short inscriptions, consisting of the name of the king and that of some high functionary or officer of state, such as "Shar-Gani-sharri, the mighty, the king of Akkad: Lugal-ushumgal, patesi of Lagash, thy servant"; here the king is addressed in the second person by the officer whose name and title were engraved upon the seal. Similar inscriptions occur upon impressions from the seals of the shakkanakku or grand vizir, the magician of the royal household, and the king's cup-bearer. The seals were obviously employed by the officials whose names occur in the second part of each inscription, the name of the king being also included to give them the royal authority. The right to use the royal name was evidently a privilege enjoyed only by the higher officials of the court.
