These divisions of the soil had a double object. On the one hand, they formed the most certain means of insuring order and discipline; and on the other hand, they supplied the inhabitants with the most convenient method for transacting their public business in common. By a police regulation which I have already mentioned, every free individual, above twelve years of age, was obliged to enrol himself in a certain association, which he could not abandon without the permission of the chief. A stranger might not remain for more than two days with a friend, unless his host gave surety for him, and at the end of forty days he was compelled to place himself under the surveillance of some association. It is remarkable that the details of these laws of classification and subordination were almost the same in all those parts of the Roman Empire occupied by the barbarians--in Gaul and Spain, as well as in England. When one of the members of a special association had committed a crime, the association was obliged to bring him to trial. This point has given rise to much discussion among learned men. {43} The County Courts. Some have maintained that the association was bail for its members, not only for their appearance before the court of justice, but also for the crime which they might have committed. I think that every Anglo-Saxon association was bound only to bring the culprit to trial. If he had made his escape, the association had to prove, sometimes by twelve and sometimes by thirty witnesses, that it knew nothing of his whereabouts; and it was fined only when it could not produce witnesses to prove that it had not abetted his escape. This obligation of every local corporation to pay for its guilty and absent members, existed also in Gaul at this time. The Gallic corporation was moreover answerable for the execution of the sentence: I do not think this was the case in England, where it was bound only to bring the culprit to trial.
