The various functionaries, governors of towns, tax-collectors, heads of stations, and officers whose duty it was to patrol the roads and look after the safety of merchants, were, for the most part, selected from among natives who had thrown in their lot with Assyria, and probably few Assyrians were to be found outside the more turbulent cities and important fortresses. The kings and chiefs whose territory was attached to a given province, either took their instructions direct from Nineveh, or were sometimes placed under the control of a resident, or _kipu_, with some sort of escort at his back, who kept watch over their movements and reported them to the suzerain, and saw that the tribute was paid regularly, and that the military service provided for in the treaties was duly rendered. Governors and residents alike kept up a constant correspondence with the court, and such of their letters as have chanced to come down to us show what a minute account of even the most trifling occurrences was required of them by the central authorities. They were not only obliged to report any fluctuation in the temper or attitude of their subordinates, or any intrigues that were being entered into across the frontier; they had also to record the transfer of troops, the return of fugitives, the pursuit of deserters, any chance scuffle between soldiers and natives, as well as the punishment inflicted on the rebellious, the appearance of a portent in the heavens, or omens noticed by the augurs. There were plenty of envious or officious tongues among their followers to report to headquarters the slightest failure of duty, and to draw attention to their negligence. Moreover, it seems certain that the object of thus compelling them to refer to the king at every turn, was not merely in order to keep him informed of all that took place in his dependencies, but also to lay bare the daily life of his prefects before his eyes. The latter were entrusted with the command of seasoned troops; they had considerable sums of money passing through their hands, and were often obliged to take prompt decisions and enter into diplomatic or military transactions on their own responsibility; in short, most of them, at any rate, who were stationed at the furthest confines of the empire were really kings in all but title, insignia, and birth. There was always the danger lest some among them should be tempted to reassert, in their own interest, the independence of the countries under their rule, and seek to found a dynasty in their midst. The strict supervision maintained over these governors generally nipped any ambition of this kind in the bud; in some cases, however, it created the very danger it was intended to prevent. If a governor who had been recalled to Nineveh or Calah in order to explain his conduct failed to clear himself completely, he at once fell into disgrace; and disgrace in Assyria, as in other countries
