The application of the narrative to North America is not, however, without its difficulties. Vespucci makes no mention of the Antilles, through which his course must have led him; perhaps not seeing them by reason of fog; or he had instructions not to concern himself with what the admiral had already discovered. He also refers to a larger work, never published, in which details were to be given. Neither does he mention the prominent peninsulas of Yucatan and Florida, nor the lofty mountain peaks which he would naturally have seen in following the Mexican coast. He claims to have sailed north-west from Pánuco 870 leagues (over dry land?) to the best harbor in the world. M. Varnhagen's explanation of this difficulty is that Vespucci simply states incidentally that he left Pánuco "tuttavia verso il Maestrale" still toward the north-west, not intending to include in this course the whole voyage of 870 leagues. All the windings of the coast and the entering and leaving of many ports or rivers must be taken into account to make up a distance of 870 leagues between Pánuco and Cape Cañaveral; and the latter port would hardly be considered the 'best harbor in the world' except by a great stretch of the imagination, or by a navigator little acquainted with good harbors. The archipelago of Ity has generally been supposed to be Hayti, but there is probably no reason for the identity beyond the resemblance of names. The Bermudas when discovered in 1522 were uninhabited, but this does not prove that they were always so; the Spaniards may have returned and captured the people for slaves. Indeed the Bermudas may have been the archipelago of San Bernardo, famous for its fierce Carib population, but generally located off the gulf of Urabá. It may even have been named by Vespucci, for on San Bernardo's day, the 20th of August, he was probably there. Thus have I given, and let me hope without prejudice, the arguments for and against this disputed voyage; and from the evidence the reader may draw his own conclusions. To me the proofs seem conclusive that Vespucci made no voyage to South America prior to 1499, when he accompanied Alonso de Ojeda. Against a North American expedition the evidence, if less conclusive, is still very strong; since the most that can be claimed in its favor is a probability that the Central American coast was visited by some navigator before 1502, and a possibility, though certainly a very slim one, that Vespucci accompanied such navigation.
