First Voyage Round the World | Page 6

those who started with that view found, when embarked on that vast expanse, that prudence dictated that they should have a moderate certainty of, by a certain time, falling in with a place of sure refreshment. The provisions they carried were bad at starting, and by the time they had fought their way through the Straits of Magellan were already worse; water was limited, and would not hold out more than a given number of days. Every voyage that is pursued tells the same story--short of water, and eagerly looking out for an opportunity of replenishing it. The winds were found to blow in fixed directions, and each voyager was fearful of deviating from the track on which it was known they would be fair, for fear of delays. And ever present in each captain's mind was the dread of the terrible scourge, scurvy. Every expedition suffered from it. Each hoped they would be exempt, and each in turn was reduced to impotence from its effects.
It was the great consideration for every leader of a protracted expedition, How can I obviate this paralyzing influence? And one after another had to confess his failure.
It is yearly becoming more difficult for us to realise these obstacles.
The prevailing winds and currents in each part of the ocean are well known to us: the exact distance and bearing from one point to another are laid down in the chart; steam bridges over calm areas, and in many cases conducts us on our entire journey at a speed but little inferior to that of land travelling by railroad; modern science preserves fresh and palatable food for an indefinite period; and, in a word, all the difficulties and most of the dangers of long voyages have disappeared.
Take one element alone in long voyages--the time required. The average progress of a ship in the eighteenth century was not more than fifty miles a day. Nowadays we may expect as much as four hundred miles in a full powered steamer, and not less than one hundred and fifty in a well-fitted sailing ship.
But navigation, and more especially the navigation of the unknown Pacific, was very different in Cook's days, when all the obstacles above mentioned impeded the explorers, and impelled them to follow a common track.
There were a few who had deviated from the common track.
The Spaniards, Mendana, Quiros, Torres, in the latter part of the sixteenth century, starting first from their colonies in Peru, had ventured along the central line of the Pacific, discovering the Marquesas, certain small coral islands, the Northern New Hebrides, and the Solomon Islands; but their voyages, mainly for fear of Drake and his successors, were kept so secret that no one quite knew where these islands lay.
Abel Tasman, in 1642, coming across the Indian Ocean from the westward, had touched at Tasmania, or, as he called it, Van Diemen's Land, had skirted the western coast of the north island of New Zealand without landing, and had stretched away to the north-east, and found the Tonga Group.
The English Buccaneers were not among these discoverers; Dampier, Woods Rogers, and others, all went from Acapulco to the Ladrones, looking out for the valuable Spanish galleons from Manila, and they added little or nothing to the knowledge of the Pacific and what it contained.
It was not therefore strange that the imagination of geographers ran riot amongst the great unknown areas. They were impressed, as they looked at the globes of the day, with the fact that, while the northern hemisphere contained much land, the southern showed either water or blank spaces; and starting with the ill-founded idea that the solid land in either hemisphere should balance, they conceived that there must be a great unknown continent in the southern part of the Pacific to make up the deficiency. This was generally designated Terra Australis Incognita, and many is the ancient chart that shows it, sketched with a free and uncontrolled hand, around the South Pole. It was held by many that Tasman had touched it in New Zealand; that Quiros had seen it near his island of Encarnacion, and again at Espiritu Santo (New Hebrides), but no one had been to see.
In George III's reign the desire to know more of this unknown ocean arose in England. The king himself took great interest in it, and for the first time since Queen Elizabeth's age, when Davis, Frobisher, Drake, Narborough, and others, had gone on voyages of discovery, the pursuit was renewed.
In 1764 the Dolphin and Tamor, under the command of Commodore Byron and Captain Mouat, sailed on a voyage round the world. They spent some time, as ordered, in exploring the Falkland Islands, and, after a two months' passage through Magellan Strait, they stood across the Pacific. They, however, also followed near the well-beaten track, and
