Spain, France, Holland, and England each sought to rival the other in the magnitude and value of their discoveries. As the primary object of each of these European potentates was the same, and it was likely to lead to much conflict of jurisdiction, the necessity of some general rule became apparent, whereby their respective claims might be acknowledged and adjudicated without resort to the arbitrament of arms. Out of this necessity grew the rule which became a part of the recognized law of nations, and which gave the preference of title to the monarch whose vessels should be the first to discover, rather than to the one who should first enter upon the possession of new lands. The exclusion under this rule of all other claimants gave to the discovering nation the sole right of acquiring the soil from the natives and of planting settlements thereon. This was a right asserted by all the commercial nations of Europe, and fully recognized in their dealings with each other; and the assertion, of such a right necessarily carried with it a modified denial of the Indian title to the land discovered. It recognized in them nothing but a possessory title, involving a right of occupancy and enjoyment until such time as the European sovereign should purchase it from them. The ultimate fee was held to reside in such sovereign, whereby the natives were inhibited from alienating in any manner their right of possession to any but that sovereign or his subjects. The recognition of these principles seems to have been complete, as is evidenced by the history of America from its discovery to the present day. France, England, Portugal, and Holland recognized them unqualifiedly, and even Catholic Spain did not predicate her title solely upon the grant of the Holy See. No one of these countries was more zealous in her maintenance of these doctrines than England. In 1496 King Henry VII commissioned John and Sebastian Cabot to proceed upon a voyage of discovery and to take possession of such countries as they might find which were then unknown to Christian people, in the name of the King of England. The results of their voyages in the next and succeeding years laid the foundation for the claim of England to the territory of that portion of North America which subsequently formed the nucleus of our present possessions. The policy of the United States since the adoption of the Federal Constitution has in this particular followed the precedent established by the mother country. In the treaty of peace between Great Britain and the United States following the Revolutionary war, the former not only relinquished the right of government, but renounced and yielded to the United States all pretensions and claims whatsoever to all the country south and west of the great northern rivers and lakes as far as the Mississippi.
