[96] Cook describes this as a small tree or shrub with five white petals shaped like those of a rose. The leaves were like a myrtle, and made an agreeably bitter beverage. If this was strongly brewed it acted like an emetic. On the way north from Dusky Bay towards Queen Charlotte Sound, six or seven waterspouts were seen. According to Cook, they were caused by whirlwinds which created a kind of funnel or tube of water, which ascended in a spiral stream up to the clouds. In one of them a bird had been enclosed, which the seamen saw being whirled round and round as it was carried upwards. It appeared to Cook that, although these spouts reached the clouds, it was not from the rainwater of the clouds being drawn down to them, but by the column of whirling water ascending from the sea to the clouds above. When in the southern Indian Ocean Cook had arranged with Captain Furneaux that if they should be separated by weather (as they were) they should rendezvous at Queen Charlotte Sound. The _Adventure_ was separated from the _Resolution_, and after searching for her in vain set out on a lonely voyage of 4200 miles through an utterly unknown sea and reduced to an allowance of 1 quart of fresh water a day. They steered for Tasmania, reached the south coast of that island, and landed there on 10 March, 1773, finding the soil very rich and the country well clothed with woods, and plenty of water falling from the rocks in brilliant cascades 200 or 300 feet perpendicularly into the sea. They were the second white men to land in Tasmania. The _Adventure_ anchored for five days in the bay since called after her. The trees of the forest they found mostly burnt or scorched near the ground, owing to the natives setting fire to the underwood, so as to make passage easy through the forest. There seemed to be little variety of trees, which were mostly of the eucalyptus kind; but there was an abundance of birds, Australian "crows" with their sharp white beaks, several kinds of duck, parakeets, and a large white bird about the size of a small eagle and very like one.[97] As for beasts, they only saw one, which was a kind of opossum (phalanger), but from the traces they saw of others (kangarus) they believed the land to contain deer. There were many signs of the natives--rough wigwams or huts,[98] in which there were bags and nets made of grass, stones and tinder for striking fire, spears sharpened at the end with a shell or stone--but the people themselves kept out of the way of the Europeans and were not once seen. [97] Probably _Haliœtus leucogaster_, a white and grey fish-eating eagle.
