Suppose 1000 Tradesmen with their Families, Watch-Makers for Instance, settled on one Spot somewhere in the Neighbourhood of _London_, [I only mention _Watch-Makers_, because it is computed, that about 1000 Families, or one-third of the City of _Geneva_ are supposed to be of that Profession.] Now the first Thing which would attract our Notice respecting Navigation, is to lay in a Provision of Sea-Coals; and a yearly Supply of this Commodity for 1000 Families would employ a good deal of Shipping: Fish would be the next Article, Sea-Fish especially, whether fresh or Salt, in respect to which a good many Sailors one Time or other must be, or must have been employed: After this, the like Observation will extend to Cyder, and to other Articles brought Coast-wise; also to Wines, Brandies, Rum, Sugars, Fruits, Oils, &c. &c. imported from Abroad: likewise to Timber of various Kinds for building or repairing, also for making a Variety of Houshold Goods; to Iron, Hemp, Linen Cloth, and other Commodities, especially those of the bulky Kind: Now here I ask, Is it possible to conceive, that, were this Group of Manufacturers to take Flight, like a Swarm of Bees, and settle in some of the Towns or Provinces of _North-America_, they either would, or could employ as many _English_ Seamen in their _new_ Situations, as they do at present in their _old_ ones? And can any Man be so absurd as to maintain such a Paradox? [Remember I limit the Matter to _English_ Seamen only; for as to _Americans_, let their Number be what it may, _Great-Britain_ never was advantaged by them. Not to mention, that several of the _American_ Provinces have disputed, or rather denied, long before the present Disturbances began, the Right of pressing Sailors for the Navy; though it is well known, that this is the only Method whereby a Navy can be manned; and though that eminent Whig, that upright, learned, and truly-patriotic Lawyer [Judge FOSTER] hath demonstratively proved in his Law-Tracts this Right to be as legally and constitutionally vested in the Crown, as any Right whatever.] I will therefore take this Point relating to Sailors for granted; [at least 'till the contrary shall be proved,] and then it will follow, that _British_ or _Irish_ Emigrations are to be considered as being very unfavourable to the Increase of _English_ Sailors, as well as of _English_ Manufacturers; and that the Loss and Detriment to the Mother-Country are very great in both Respects.
