The restless ambition of the Cabots incited them to a further voyage in February 1498, the charter on this occasion being granted only to the father. They again started from Bristol, and sailed along the North American coasts from the ice-bound shores of Newfoundland[7] to the sunny Carolinas or Florida. The younger Cabot afterwards wrote that he sailed "unto the Latitude of 67 degrees and a halfe under the North Pole ... finding still the open Sea without any maner of impediment, he thought verily by that way to have passed on still the way to Cathaia which is in the East."[8] This voyage is recorded by Sir Humphrey Gilbert, and was frequently quoted as a reason for England's claim to North America. "The countreys lying north of Florida, God hath reserved the same to be reduced unto Christian civility by the English nation. For not long after that Christopher Columbus had discovered the Islands and continent of the West Indies for Spaine, John and Sebastian Cabot made discovery also of the rest from Florida northwards to the behoofe of England."[9] The Cabots disappear from English history for a time and there are no records of the reception of this voyage. It was undoubtedly of twofold importance; it started that "will o' the wisp" of the North-West Passage, that led so many men to risk and lose their lives; and it may also be regarded as the foundation-stone of the English power in the West. The next few years of the history of the exploration of America is filled with the records of Spaniards, Italians, and Frenchmen. The voyage of the Bristol merchants by which North America had just been discovered had no effect, and awakened no enthusiasm in the hearts of the English during the early portion of the sixteenth century. Henry VII. and his more adventurous son were both such severe and orthodox Catholics that they hesitated to trespass upon the limitations laid down by the bull of Alexander VI., by which everything on the western side of an imaginary line between the forty-first and forty-fourth meridians west of Greenwich belonged to Spain; while the Brazil coast, the East Indies, and Africa south of the Canary Islands fell to Portugal. Between 1500 and 1550 only two true voyages of discovery have been chronicled. The first was in 1527, when a canon of St Paul's, erroneously named Albert de Prado, sailed with two ships in search of the Indies. It is probable that this was the voyage of John Rut of the Royal Navy, with whom, there is reason to suppose, a Spaniard, called Albert de Prado, sailed. They failed to make any real discoveries, but brought back a cargo of fish from the inhospitable shores of Newfoundland and Labrador. The second voyage was that of Master Hore, in 1536, who, it is supposed, set out in the spirit of a Crusader, but who was more probably a briefless barrister accompanied by "many gentlemen of the Innes of Court and of the Chancery."[10] They were shipwrecked on
