Reasons for an augmentation of at least twelve thousand mariners, to be employed in the merchants-service, and coasting-trade [electronic resource] : with some thoughts on the means of providing for a number of our seamen, after the present war is finished; also to support a constant additional Marine-Force, in order to the cheaper and more expeditious decision of our future Quarrels; and to render Pressing necessary in a less degree. Also to promote the Benefit of Ship-Owners and Under-Writers; to extend, the Navigator of these Kingdoms, and to take care of the Poor who incline to a Sea-Life. Likewise, to make Provision for the Boys fitted out by the Marine-Society, when they shall be discharged from the King's Ships. With some Remarks on the Magdalen-House.
