Thus [1321b] we have explained on what principles a democracy and an oligarchy ought to be established. CHAPTER VIII After what has been said I proceed next to treat particularly of the magistrates; of what nature they should be, how many, and for what purpose, as I have already mentioned: for without necessary magistrates no state can exist, nor without those which contribute to its dignity and good order can exist happily: now it is necessary that in small states the magistrates should be few; in a large one, many: also to know well what offices may be joined together, and what ought to be separated. The first thing necessary is to establish proper regulators in the markets; for which purpose a certain magistrate should be appointed to inspect their contracts and preserve good order; for of necessity, in almost every city there must be both buyers and sellers to supply each other's mutual wants: and this is what is most productive of the comforts of life; for the sake of which men seem to have joined together in one community. A second care, and nearly related to the first, is to have an eye both to the public and private edifices in the city, that they may be an ornament; and also to take care of all buildings which are likely to fall: and to see that the highways are kept in proper repair; and also that the landmarks between different estates are preserved, that there may be no disputes on that account; and all other business of the same nature. Now, this business may be divided into several branches, over each of which in populous cities they appoint a separate person; one to inspect the buildings, another the fountains, another the harbours; and they are called the inspectors of the city. A third, which is very like the last, and conversant nearly about the same objects, only in the country, is to take care of what is done out of the city. The officers who have this employment we call inspectors of the lands, or inspectors of the woods; but the business of all three of them is the same. There must also be other officers appointed to receive the public revenue and to deliver it out to those who are in the different departments of the state: these are called receivers or quaestors. There must also be another, before whom all private contracts and sentences of courts should be enrolled, as well as proceedings and declarations. Sometimes this employment is divided amongst many, but there is one supreme over the rest; these are called proctors, notaries, and the like. Next to these is an officer whose business is of all others the most necessary, and yet most difficult; namely, to take care that sentence is executed upon those who are condemned; and that every one pays the fines laid on him; and also to have the charge of those who are in prison. [1322a] This office is very disagreeable on account of the odium attending it, so that no one will engage therein without it is made very profitable, or, if they do,
