"A little later a quarrel arose. The crew had taken possession of some tortoises which the natives claimed, without having in the least assisted in capturing them. When they found that their demand was not acceded to, they retired in fury, and set fire to the shrubs in the midst of which the English encampment was situated. The latter lost all their combustible commodities in the conflagration, and the fire, leaping from hill to hill, afforded a magnificent spectacle during the night." Meantime Messrs. Banks, Solander, and others, enjoyed many successful hunts. They killed kangaroos, opossums, a species of pole-cat, wolves, and various kinds of serpents, some of which were venomous. They also saw numbers of birds, kites, hawks, cockatoos, orioles, paroquets, pigeons, and other unknown birds. [Illustration: Tahitian fleet off Oparee. (Fac-simile of early engraving.)] After leaving Endeavour River, Cook had good opportunities of testing the difficulties of navigation in these latitudes. Rocks and shallows abounded. It was necessary to cast anchor in the evening, for it was impossible to proceed at night through this labyrinth of rocks without striking. The sea, as far as the eye could reach, appeared to dash upon one line of rocks more violently than upon the others; this appeared to be the last. Upon arriving there, after five days' struggle with a contrary wind, Cook discovered three islands stretching four or five leagues to the north. But his difficulties were not over. The vessel was once more surrounded by reefs and chains of low islets, amongst which it was impossible to venture. Cook was inclined to think it would be more prudent to return and seek another passage. But such a detour would have consumed too much time, and have retarded his arrival in the East Indies. Moreover there was an insurmountable obstacle to this course. Three months' provisions were all that remained. The situation appeared desperate, and Cook decided to steer as far as possible from the coast, and to try and pass the exterior line of rocks. He soon found a channel, which shortly brought them to the open sea. "So happy a change in the situation," says Kippis, "was received with delight. The English were full of it, and openly expressed their joy. For nearly three months they had been in perpetual danger. When at night they rested at anchor, the sound of an angry sea forced them to remember that they were surrounded by rocks, and that, should the cable break, shipwreck was inevitable. They had travelled over 360 miles, and were forced to keep a man incessantly throwing the line and sounding the rocks through which they navigated. Possibly no other vessel could furnish an example of such continued effort."
