Persons wishing to organise a corps to form part of a brigade of Royal Naval Artillery Volunteers should place themselves in communication with the Secretary of the Admiralty. Whenever it is practicable, a brigade will be formed at each of the large ports in the kingdom, and the batteries composing the brigade will be raised in the immediate neighbourhood of the port. When the Volunteers are not of sufficient strength at any port to form a brigade, the batteries enrolled on a part of the coast formed into a district will be formed into a brigade, and will be called a district brigade. The object of this organisation is to unite separate batteries under one head, to secure uniformity among them, and to afford them the advantage of an officer-instructor. Candidates for enrolment as members of the Royal Naval Artillery Volunteers must be of good character, and physically fit for the service; their eligibility will be judged by the commanding officer of the corps, assisted by such others of the corps as he may think fit to appoint for that purpose. No person below the age of 17 is to be enrolled in the corps without the special authority of the Admiralty. Boys of 14 years of age and upwards may be enrolled for the purpose of being trained as buglers. Men belonging to any other force liable to be called out for service in case of war are not to be enrolled. Apprentices are not to be enrolled without the consent of their masters. Persons dismissed from any other service or corps for misconduct are not to be enrolled without the special sanction of the Admiralty.
