He struck Australia at its south-east point, and followed the whole coast to the northward, mapping it as he went. When nearing the northern end the voyage nearly came to a premature conclusion by the ship grounding on a coral reef, twenty miles from the land. Cook's seamanship was, however, equal to the occasion. The ship was got off, much damaged and leaking severely, and carried into a little port they discovered not far off. Here she was cleared out and laid upon the ground, the tide sufficing to dry enough of her bottom to let the carpenters repair it. The wisdom of Cook's choice of a ship of the build of the Endeavour was here very apparent. It was not every ship that could be safely beached in this way without danger of falling over. After long delay she proceeded on her voyage, and soon had a second narrow escape. The long line of coral reefs that front the northern part of Eastern Australia, for a distance of 1200 miles, approach the coast about the place where the ship had grounded. The passage between the outer reef and the land is strewn with shoals, and finding his further progress much impeded by them, and fearful of a repetition of his disaster, Cook with some difficulty found a channel to seaward, and gained the open ocean. He was, however, yet determined to follow the land he was exploring, and more especially to solve the great question as to whether Australia was joined to New Guinea or no; and three days after his escape from the line of reefs he found himself with a light wind, embayed on the outer side of them, with the reefs close to him, and the ship drifting slowly but surely on them, the heavy swell of the great ocean breaking mountains high on their outer edge. Here again calmness and promptitude saved him, and the ship was pushed through a narrow channel in these terrible reefs into the smooth, though reef-dotted, waters within. No event in the voyage is more dramatically narrated, though without any exaggeration, than this hair-breadth escape. With the caution born of recent dangers, Cook now slowly found his way through the maze of reefs, by a route that no one has again followed, to the northern point of Australia, and was rewarded for his pertinacity by finding the channel now known as Torres Strait, which led him between New Guinea and Australia.
