And no man could change his habitation without a warrant or certificate from the borsholder of the tithing to which he formerly belonged.
When any person, in any tithing or decennary, was guilty of a crime, the borsholder was summoned to answer for him; and if he were not willing to be surety for his appearance, and his clearing himself, the criminal was committed to prison, and there detained till his trial.

If he fled, either before or after finding sureties, the borsholder and decennary became liable to inquiry, and were exposed to the penalties of law.
Thirty-one days were allowed them for producing the criminal; and if that time elapsed without their being able to find him, the borsholder, with two other members of the decennary, was obliged to appear, and, together with three chief members of the three neighboring decennaries, (making twelve in all,) to swear that his decennary was free from all privity, both of the crime committed, and of the escape of the criminal.
If the borsholder could not find such a number to answer for their innocence, the decennary was compelled by fine to make satisfaction to the king, according to the degree of the offence.[*] [* Leges St.Edw.cap.

Such a regular distribution of the people, with such a strict confinement in their habitation, may not be necessary in times when men are more inured to obedience and justice; and it might, perhaps, be regarded as destructive of liberty and commerce in a polished state; but it was well calculated to reduce that fierce and licentious people under the salutary restraint of law and government.

But Alfred took care to temper these rigors by other institutions favorable to the freedom of the citizens; and nothing could be more popular and liberal than his plan for the administration of justice.
