In England, as well as Scotland, the right to erect and hold ports and havens is vested in the crown; though a subject may have such right by charter, grant, or prescrip- tion, but in all cases charged with the right of the public to use it. In England such grantee is bound to repair, but in Scotland only to the extent of the dues received. The insufficiency of the common-law power led to an extended course of legis- lation for the control of ports and harbors, through what is known in Great Britain as the harbor authority, which is vested in commissioners or bodies corporate or other- wise. Such bodies are charged with the duty of general supervision of the con- struction, extension, improvement, and lighting of the harbor and collection of dues therefrom. The general consolidation act of 10 Vict. c. 271, defined these duties and powers in detail as did the general act of 24 & 25 Vict. c. 47, supplemented by various local acts. In Torts. To receive clandestinely or without lawful authority a person for the purpose of so concealing him that another having a right to the lawful custody of such person shall be deprived of the same.

For example, the harboring of a wife or an apprentice in order to deprive the husband or the master of them; or, in a less technical sense, it is the reception of persons improperly; Poll. Torts 275; 10 Ν. H. 247; 5 111. 498. It may be aptly used to describe the fur- nishing of shelter, lodging, or food clandes- tinely or with concealment, and under certain circumstances, may be equally ap- plicable to those acts divested of any accom panying secrecy; 55 Fed. Rep. 415. The harboring of such persons will sub- ject the harborer to an action for the injury; but, in order to put him completely in the wrong, a demand should be made for their restoration, for in cases where the harborer has not committed any other wrong than merely receiving the plaintiff's wife, child, or apprentice, he may be under no obliga- tion to return them without a demand; 1 Chit.
