His regulations as to the public "posts" and "spies" will show how much he cared for the interests of the state. The earlier Emperors, in order to gain the most speedy information concerning the movements of the enemy in each territory, seditions or unforeseen accidents in individual towns, and the actions of the governors and other officials in all parts of the Empire, and also in order that those who conveyed the yearly tribute might do so without danger or delay, had established a rapid service of public couriers according to the following system:--As a day's journey for an active man, they settled eight stages, sometimes fewer, but never less than five. There were forty horses in each stage and a number of grooms in proportion. The couriers who were intrusted with this duty, by making use of relays of excellent horses, frequently covered as much ground in one day by this means as they would otherwise have covered in ten, when carrying out the above commissions. In addition, the landed proprietors in each country, especially those whose estates were in the interior, reaped great benefit from these posts; for, by selling their surplus corn and fruit every year to the state for the support of the horses and grooms, they gained considerable revenue. By this means the state received, without interruption, the tribute due from each, and, in turn, reimbursed those who furnished it, and thus everything was to the advantage of the state. Such was the old system. But Justinian, having commenced by suppressing the post between Chalcedon and Dakibiza, compelled the couriers to carry all despatches from Byzantium to Helenopolis by sea. They unwillingly obeyed; for, being obliged to embark upon small skiffs, such as were generally used for crossing the strait, they ran great risk of being shipwrecked, if they met with stormy weather. For, since great speed was enjoined upon them, they were unable to wait for a favourable opportunity for putting out to sea, when the weather was calm. It is true that he maintained the primitive system on the road to Persia, but for the rest of the East, as far as Egypt, he reduced the number of posts to one, for a day's journey, and substituted a few asses for the horses, so that the report of what was taking place in each district only reached Byzantium with difficulty and long after the events had occurred, when it was too late to apply any remedy; and, on the other hand, the owners of estates found no benefit from their products, which were either spoilt or lay idle.
