Having thus regulated the city and its concerns, he augmented the population of Italy by planting in it no less than twenty-eight colonies,A.U.C. 726 and greatly improved it by public works, and a beneficial application of the revenues. In rights and privileges, he rendered it in a measure equal to the city itself, by inventing a new kind of suffrage, which the principal officers and magistrates of the colonies might take at home, and forward under seal to the city, against the time of the elections. To increase the number of persons of condition, and of children among the lower ranks, he granted the petitions of all those who requested the honour of doing military service on horseback as knights, provided their demands were seconded by the recommendation of the town in which they lived; and when he visited the several districts of Italy, he distributed a thousand sesterces a head to such of the lower class as presented him with sons or daughters.

The more important provinces, which could not with ease or safety be entrusted to the government of annual magistrates, he reserved for his own administration: the rest he distributed by lot amongst the proconsuls; but sometimes he made exchanges, and frequently visited most of both kinds in person. Some cities in alliance with Rome, but which by their great licentiousness were hastening to ruin, he deprived of their independence. Others, which were much in debt, he relieved, and rebuilt such as had been destroyed by earthquakes. To those that could produce any instance of their having deserved well of the Roman people, he presented the freedom of Latium, or even that of the City. There is not, I believe, a province, except Africa and Sardinia, which he did not visit. After forcing Sextus Pompeius to take refuge in those provinces, he was indeed preparing to cross over from Sicily to them, but was prevented by continual and violent storms, and afterwards there was no occasion or call for such a voyage.

Kingdoms, of which he had made himself master by the right of conquest, a few only excepted, he either restored to their former possessors, As in the case of Herod, Joseph. Antiq. Jud. xv. 10. or conferred upon aliens. Between kings in alliance with Rome, he encouraged most intimate union; being always ready to promote or favour any proposal of marriage or friendship amongst them; and, indeed, treated them all with the same consideration, as if they were members and parts of the empire. To such of them as were minors or lunatics he appointed guardians, until they arrived at age, or recovered their senses; and the sons of many of them he brought up and educated with his own.

With respect to the army, he distributed the legions and auxiliary troops throughout the several provinces. He stationed a fleet at Misenum, and another at Ravenna, for the protection of the Upper and Lower Seas.The Adriatic and the Tuscan. A certain number of the forces were selected, to occupy the posts in the city, and partly for his own body-guard; but he dismissed the Spanish guard, which he retained about him till the fall of Antony; and also the Germans, whom he had amongst his guards, until the defeat of Varus. Yet he never permitted a greater force than three cohorts in the city, and had no (praetorian) camps.It was first established by Tiberius. See c. xxxvii. The rest he quartered in the neighbourhood of the nearest towns, in winter and summer camps. All the troops throughout the empire he reduced to one fixed model with regard to their pay and their pensions; determining these according to their rank in the army, the time they had served, and their private means; so that after their discharge, they might not be tempted by age or necessities to join the agitators for a revolution. For the purpose of providing a fund always ready to meet their pay and pensions, he instituted a military exchequer, and appropriated new taxes to that object. In order to obtain the earliest intelligence of what was passing in the provinces, he established posts, consisting at first of young men stationed at moderate distances along the military roads, and afterwards of regular couriers with fast vehicles; which appeared to him the most commodious, because the persons who were the bearers of dispatches, written on the spot, might then be questioned about the business, as occasion occurred.

In sealing letters-patent, rescripts, or epistles, he at first used the figure of a sphinx, afterwards the head of Alexander the Great and at last his own, engraved by the hand of Dioscorides; which practice was retained by the succeeding emperors. He was extremely precise in dating his letters, putting down exactly the time of the day or night at which they were dispatched.
