King Henry was no sooner made acquainted with the success of John Cabot, than he gave an invitation to mariners of character and ability to enter his service, for the purpose of attempting further discoveries. Cabot declared, he doubted not to make discoveries for him equally honourable and advantageous as those Columbus had made for Ferdinand and Isabella. Accordingly, terms were proposed and agreed on between them. "Henry, in the eleventh year of his reign, gave a commission to John Cabot and his three sons, Sebastian, Lewis, and Sancius, and their heirs, allowing them full power to sail to all countries and seas of the east, west, and north, under English colours, with five ships of such burden and force as they should think proper, and with as many mariners as they should chuse to take on their own cost and charges, to seek out and discover all the isles, countries, regions and provinces of heathens and infidels they could find, which to all Christians before that time had remained unknown." In these letters-patent though it appears that Henry granted them a right to occupy and possess such lands and countries as they should find and conquer, yet he laid them under an obligation to erect the English standard in every place, and reserved to himself and his heirs the dominion, title and jurisdiction of all the towns, castles, isles and lands they should discover; so that whatever acquisitions they should make, they would only occupy them as vassals of the crown of England. And lest they should be inclined to go to some foreign port, he expressly bound them to return to Bristol, and to pay him and his heirs one fifth part of all the capital gains, after the expences of the voyage were deducted: and, for their encouragement, he invested them with full powers to exclude all English subjects, without their particular licence, from visiting and frequenting the places they should discover. [Sidenote] A. D. 1497. [Sidenote] The discovery of Sebastian Cabot. Soon after receiving this commission from the king, John Cabot died; and his son Sebastian, who was also a skilful navigator, set sail in 1497, with the express view of discovering a north-west passage to the eastern spice islands. Directing his course by his father's journals to the same point, he proceeded beyond the 67th degree of north latitude; and it is affirmed, that he would have advanced farther, had not his crew turned mutinous and ungovernable, and obliged him to return to the degree of latitude 56. From thence, in a south-west course, he sailed along the coast of the continent, as far as that part which was afterwards called Florida, where he took his departure, and returned to England. Thus England claims the honour of discovering the continent of North America, and by those voyages of John and Sebastian Cabot, all that right and title to this extensive region, founded on prior discovery, must be vested in the crown of England.
