That is, When that advantageous Island shall be well peopled, it may become so strong and potent as to over-power the neighbouring Isles, and also a part of the main Land, especially the Maritime parts. And already in their infancy they have given testimony of their power and courage in their bold attempts upon _Campeche_ and _Santa Martha_; and in that notable attempt upon _Panama_ on the Western side of _America_: especially considering this Island is sufficiently large to contain a numerous people, of a Northern and warlike descent, addicted to martial affairs both by Sea and Land, and advantageously seated to infest their neighbours both of the Isles and the Continent, and like to be a receptacle for Colonies of the same originals from _Barbadoes_ and the neighbour Isles. _When_ Spain _shall be in_ America _hid; And_ Mexico _shall prove a_ Madrid. That is, When _Spain_, either by unexpected disasters, or continued emissions of people into _America_, which have already thinned the Country, shall be farther exhausted at home: or when, in process of time, their Colonies shall grow by many accessions more than their Originals, then _Mexico_ may become a _Madrid_, and as considerable in people, wealth and splendour; wherein that place is already so well advanced, that accounts scarce credible are given of it. And it is so advantageously seated, that, by _Acapulco_ and other Ports on the South Sea, they may maintain a communication and commerce with the Indian Isles and Territories, and with _China_ and _Japan_, and on this side, by _Porto Belo_ and others, hold correspondence with _Europe_ and _Africa_. _When_ Mahomet's _Ships in the Baltick shall ride._ Of this we cannot be out of all fear; for, if the Turk should master _Poland_, he would be soon at this Sea. And from the odd constitution of the Polish Government, the divisions among themselves, jealousies between their Kingdom and Republick; vicinity of the Tartars, treachery of the Cossacks, and the method of Turkish Policy, to be at Peace with the Emperour of _Germany_ when he is at War with the Poles, there may be cause to fear that this may come to pass. And then he would soon endeavour to have Ports upon that Sea, as not wanting Materials for Shipping. And, having a new acquist of stout and warlike men, may be a terrour unto the confiners on that Sea, and to Nations which now conceive themselves safe from such an Enemy. _When_ Africa _shall no more sell out their Blacks._ That is, When African Countries shall no longer make it a common Trade to sell away the people to serve in the drudgery of American Plantations. And that may come to pass when ever they shall be well civilized, and acquainted with Arts and Affairs sufficient to employ people in their Countries: if also they should be converted to Christianity, but especially unto Mahometism; for then they would never sell those of their Religion to be Slaves unto Christians.
