Several causes are supposed to have contributed to suspend the pursuits of the English in America. Previous to its discovery, the Portuguese had explored the Azores, or Western Islands; in consequence of which they claimed this continent, and contended for the exclusion of the Spaniards from the Western Ocean. The controversy was decided by the Pope, who, on the 7th of May 1493, of his own "mere liberality and certain knowledge, and the plenitude of apostolic authority," granted to Spain, the countries discovered or to be discovered by her, to the westward of a line to be drawn from pole to pole, a hundred leagues west of the Azores; (excepting such countries as might be in the possession of any other Christian prince antecedent to the year 1493;) and to Portugal, her discoveries eastward of that line. The validity of this grant was probably strengthened, in the opinion of Henry, by other circumstances. He set a high value on the friendship of the King of Spain, with whom he was then negotiating the marriage which afterwards took place between his eldest son and Catharine, the daughter of that monarch. Ferdinand was jealous to excess of all his rights; and Henry was not inclined to interrupt the harmony subsisting between the two crowns, by asserting claims to the country discovered by Cabot, which was obviously within the limits to which the pretensions of Spain extended. [Sidenote: Renewed by Elizabeth.] The fisheries of Newfoundland were carried on by individuals, to a considerable extent, and a paltry traffic was continued with the natives; but no serious design of acquiring territory, and planting colonies in America was formed until the reign of Elizabeth, when a plan for making permanent settlements was proposed and patronized by several persons of rank and influence. To select a man qualified for this arduous task, and disposed to engage in it, was among the first objects to which their attention was directed. Sir Humphry Gilbert had rendered himself conspicuous by his military services, and by a treatise concerning the north-west passage, in which great ingenuity and learning, are stated by Dr. Robertson, to be mingled with the enthusiasm, the credulity, and sanguine expectation which incite men to new and hazardous undertakings. On this gentleman the adventurers turned their eyes, and he was placed at the head of the enterprise. On the 11th of June 1578, he obtained letters patent from the Queen, vesting in him the powers that were required; on receiving which, he, with the associates of his voyage, embarked for America. But his success did not equal his expectations. The various difficulties inseparable from the settlement of a distant, unexplored country, inhabited only by savages; the inadequacy of the supplies which could be furnished for a colony by the funds of a few private individuals; the misfortune of having approached the continent too far towards the north, where the cold barren coast of Cape Breton was rather
