[4] He also portioned out the land among the demes into thirty parts, ten belonging to the suburbs, ten to the coast, and ten to the inland district; and he gave these parts the name of Thirds, and assigned them among the Tribes by lot, three to each, in order that each Tribe might have a share in all the districts. And he made all the inhabitants in each of the demes fellow-demesmen of one another,1 in order that they might not call attention to the newly enfranchised citizens by addressing people by their fathers' names, but designate people officially by their demes; owing to which Athenians in private life also use the names of their demes as surnames.2
