Matters of detail relating to punishments and modes of procedure, and summonses, and witnesses to summonses, do not require the mature wisdom of the aged legislator; the younger generation may determine them according to their experience; but when once determined, they shall remain unaltered.
The following are to be the regulations respecting handicrafts:--No citizen, or servant of a citizen, is to practise them.

For the citizen has already an art and mystery, which is the care of the state; and no man can practise two arts, or practise one and superintend another.

No smith should be a carpenter, and no carpenter, having many slaves who are smiths, should look after them himself; but let each man practise one art which shall be his means of livelihood.

The wardens of the city should see to this, punishing the citizen who offends with temporary deprival of his rights--the foreigner shall be imprisoned, fined, exiled.

Any disputes about contracts shall be determined by the wardens of the city up to fifty drachmae--above that sum by the public courts.
No customs are to be exacted either on imports or exports.
