It was not until November 1st that the Norfolk sailed from the Furneaux Islands on the flood-tide westward. The intervening time had been occupied with detailed exploring and surveying work. Soundings and observations were made, capes, islands and inlets were charted and named. The part of Flinders' narrative dealing with these phases abounds in detail, noted with the most painstaking particularity. Such fulness does not make attractive literature for the reader who takes up a book of travel for amusement. But it was highly important to record these details at the time of the publication of Flinders' book, when the coasts and seas of which he wrote were very little known; and it has to be remembered that he wrote as a scientific navigator, setting down the results of his work with completeness and precision for those interested in his subject, not as a caterer for popular literary entertainment. He preferred the interest in his writing to lie in the nature of the enterprise described and the sincerity with which it was pursued rather than in such anecdotal garniture and such play of fancy as can give charm to the history of a voyage. His book was a substantial contribution to the world's knowledge, and it is his especial virtue to have set down his facts with such exactitude that our tests of them, where they are still capable of being tested, earn him credit for punctilious veracity in respect of those observations on wild life and natural phenomena as to which we have to rely upon his written word. He never succumbs to the common sin of travellers--writing to excite astonishment in the reader, rather than to tell the exact truth as he found it. He was by nature and training an exact man. On the afternoon of November 3rd the sloop entered the estuary of the river Tamar, on which, forty miles from the mouth, now stands the fine city of Launceston. It was a discovery of first-class importance. Apart from the pleasure which they derived from having made it, the two friends were charmed with the beauty of their surroundings. They derived the most favourable impression of the quality of the land and its suitableness for settlement. They worked up the river for several miles, but time did not permit them to follow it as far as it was navigable. Thus they did not reach the site of the present city, and left the superb gorge and cataract to be discovered by Collins when he entered the Tamar again in 1804. The harbour was subsequently named Port Dalrymple by Hunter, after Alexander Dalrymple, the naval hydrographer.
