Australasia (it is necessary, if wearisome, to repeat) consists of islands, great, small, and very small; Australia being so large an island that it ranks as the fifth and smallest of the continents. The insular character of Australasia has caused most of the great adventures connected with its discovery and colonization to be extraordinary feats of ocean rather than of land travel. But when we consider the size of the sailing ships, or of the mere junks, boats, or canoes in which some of the journeys were made, and the fact that the home of the explorers was not two, three, or four thousand miles away across the sea (as in the discovery of America and the West African coast), but more than treble that distance; that these hardy adventurers had to reach the unknown islands of the Pacific either round the stormy Cape of Good Hope or the still more stormy Cape Horn in ships on which we might hesitate to embark in order to cross the Bay of Biscay or the Irish Channel: the achievements of the Australasian pioneers in the sixteenth, seventeenth, eighteenth, and early nineteenth centuries become almost unbelievable in their heroism and power of endurance. The _Victoria_ of Magellan's fleet which sailed from Spain to the Pacific and back across the Atlantic and Indian oceans was of 85 tons capacity! Matthew Flinders in 1803 crossed the Indian Ocean from North Australia to Mauritius in a schooner of 29 tons! Sir James Brooke sailed in 1883 from the mouth of the Thames to conquer North Borneo from the pirates in a sailing yacht of 148 tons.
