England to South Africa to run clear across the ocean on a long stretch till within sight of the coast of Brazil before turning towards the Cape of Good Hope. All, however, that we can deduce from accidental voyages, like that of the Spaniard, Alvarez de Cabral, across the ocean is that even if there had been no other way for mankind to reach America they could have landed there by ship from the Old World. In such a case, of course, the coming of man to the American continent would have been an extremely recent event in the long history of the world. It could not have occurred until mankind had progressed far enough to make vessels, or at least boats of a simple kind. But there is evidence that man had appeared on the earth long before the shaping of the continents had taken place. Both in Europe and America the buried traces of primitive man are vast in antiquity, and carry us much further back in time than the final changes of earth and ocean which made the continents as they are; and, when we remember this, it is easy to see how mankind could have passed from Asia or Europe to America. The connection of the land surface of the globe was different in early times from what it is to-day. Even still, Siberia and Alaska are separated only by the narrow Bering Strait. From the shore of Asia the continent of North America is plainly visible; the islands which lie in and below the strait still look like stepping-stones from continent to continent. And, apart from this, it may well have been that farther south, where now is the Pacific ocean, there was formerly direct land connection between Southern Asia and South America. The continuous chain of islands that runs from the New Hebrides across the South Pacific to within two thousand four hundred miles of the coast of Chile is perhaps the remains of a sunken continent. In the most easterly of these, Easter Island, have been found ruined temples and remains of great earthworks on a scale so vast that to believe them the work of a small community of islanders is difficult. The fact that they bear some resemblance to the buildings and works of the ancient inhabitants of Chile and Peru has suggested that perhaps South America was once merely a part of a great Pacific continent. Or again, turning to the other side of the continent, it may be argued with some show of evidence that America and Africa were once connected by land, and that a sunken continent is to be traced between Brazil and the Guinea coast.
