With the view of enlisting, in support of the Naval Volunteer movement, the potent influences which are derived from the esprit de corps, wherever it may reasonably and prudently be encouraged, it is proposed to associate certain batteries in the London brigade with some of the principal rowing and Corinthian yacht clubs on the Thames, and to give commissions to any gentlemen, otherwise eligible, who are instrumental in raising a full battery of Naval Volunteers. [Sidenote: The rowing and Corinthian yacht clubs.] The following list of some of the principal rowing clubs, will serve to show the large number of gentlemen, from whom assistance may be expected, in promoting the success of a movement for extending the Volunteer service to a certain sphere of naval operations; Name of rowing club Number of members London 480 Kingston 425 Thames 300 Ino 300 Waldegrave 200 Twickenham 175 West London 170 Oscillators 162 North 150 Grove Park 150 Isleworth 100 Ilex 100 Molesey -- The Corinthian yacht clubs on the Thames are equally able to render assistance, and are indeed capable of raising, if they think fit, an entire brigade for the Royal Naval Artillery Volunteer Corps. The resources of the clubs located on the banks of the Thames have been particularly specified; because the present writer, in his connection with the movement under consideration, is more immediately identified with that river. Readers of these pages, residing in the vicinity of any of our great ports, will doubtless be able to discover equally ample materials for the foundation of a sufficient force, for the purposes of co-operation in the defence of the coast, in their own neighbourhood. A corps, though it may be raised at some distance from the sphere of its intended operations, in the event of threatened invasion, will not be the less valuable for the defence of a great port.
