Let no one pay any duty either on the importation or exportation of goods; and as to frankincense and similar perfumes, used in the service of the Gods, which come from abroad, and purple and other dyes which are not produced in the country, or the materials of any art which have to be imported, and which are not necessary--no one should import them; nor, again, should any one export anything which is wanted in the country.

Of all these things let there be inspectors and superintendents, taken from the guardians of the law; and they shall be the twelve next in order to the five seniors.

Concerning arms, and all implements which are required for military purposes, if there be need of introducing any art, or plant, or metal, or chains of any kind, or animals for use in war, let the commanders of the horse and the generals have authority over their importation and exportation; the city shall send them out and also receive them, and the guardians of the law shall make fit and proper laws about them.

But let there be no retail trade for the sake of moneymaking, either in these or any other articles, in the city or country at all.
With respect to food and the distribution of the produce of the country, the right and proper way seems to be nearly that which is the custom of Crete; for all should be required to distribute the fruits of the soil into twelve parts, and in this way consume them.

Let the twelfth portion of each as for instance of wheat and barley, to which the rest of the fruits of the earth shall be added, as well as the animals which are for sale in each of the twelve divisions, be divided in due proportion into three parts; one part for freemen, another for their servants, and a third for craftsmen and in general for strangers, whether sojourners who may be dwelling in the city, and like other men must live, or those who come on some business which they have with the state, or with some individual.
