51. Those who have charge of the city are divided into six bodies of five each. The first has the inspection of everything relating to the mechanical arts; the second entertain strangers, assign lodgings, observe their mode of life, by means of attendants whom they attach to them, escort them out of the country on their departure; if they die, take charge of their property, have the care of them when sick, and when they die, bury them. The third class consists of those who inquire at what time and in what manner births and deaths take place, which is done with a view to tax (on these occasions), and in order that the deaths and births of persons both of good and bad character should not be concealed. The fourth division consists of those who are occupied in sales and exchanges; they have the charge of measures, and of the sale of the products in season, by a signal. The same person is not allowed to exchange various kinds of articles, except he pays a double tax. The fifth division presides over works of artisans, and disposes of articles by public notice. The new are sold apart from the old, and there is a fine imposed for mixing them together. The sixth and last comprises those who collect the tenth of the price of the articles sold. Death is the punishment for committing a fraud with regard to the tax. These are the peculiar duties performed by each class, but in their collective capacity they have the charge both of their own peculiar province and of civil affairs, the repairs of public works, prices[389] of articles, of markets, harbours, and temples. 52. Next to the magistrates of the city is a third body of governors, who have the care of military affairs. This class also consists of six divisions, each composed of five persons. One division is associated with the chief naval superintendent, another with the person who has the charge of the bullock-teams, by which military engines are transported, of provisions both for the men and beasts, and other requisites for the army. They furnish attendants, who beat a drum, and carry gongs;[390] and besides these, grooms, mechanists, and their assistants. They despatch by the sound of the gong the foragers for grass, and insure expedition and security by rewards and punishments. The third division has the care of the infantry; the fourth, of the horses; the fifth, of the chariots; the sixth, of the elephants. There are royal stables for the horses and elephants. There is also a royal magazine of arms; for the soldier returns his arms to the armoury, and the horse and elephant to the stables. They use the elephants without bridles. The chariots are drawn on the march by oxen. The horses are led by a halter, in order that their legs may not be chafed and inflamed, nor their spirit damped, by drawing chariots. Besides the charioteer, there are two persons who fight by his side in the chariot. With the elephant are four persons, the driver and three bowmen, who discharge arrows from his back.
