general, I have the greatest reason to hope that it will be found as free from error as any that has not been corrected by subsequent and successive observations. The latitudes and longitudes of all, or most of the principal head-lands and bays, may be confided in, for we seldom failed of getting an observation once at least every day, by which to correct the latitude of our reckoning, and observations for settling the longitude were equally numerous, no opportunity that was offered by the sun and moon being suffered to escape. It would be injurious to the memory of Mr. Green, not to take this opportunity of attesting that he was indefatigable both in making observations and calculating upon them; and that, by his instructions and assistance, many of the petty officers were enabled both to observe and calculate with great exactness. This method of finding the longitude at sea, may be put into universal practice, and may always be depended upon within half a degree, which is sufficient for all nautical purposes. If, therefore, observing and calculating were considered as necessary qualifications for every sea officer, the labours of the speculative theorist to solve this problem might be remitted, without much injury to mankind: neither will it be so difficult to acquire this qualification, or put it in practice, as may at first appear; for, with the assistance of the nautical almanack, and astronomical ephemeris, the calculations for finding the longitude will take up little more time than the calculation of an azimuth for finding the variation of the compass. CHAP. VI. DEPARTURE FROM NEW SOUTH WALES; A PARTICULAR DESCRIPTION OF THE COUNTRY, ITS PRODUCTS, AND PEOPLE: A SPECIMEN OF THE LANGUAGE, AND SOME OBSERVATIONS UPON THE CURRENTS AND TIDES. OF this country, its products, and its people, many particulars have already been related in the course of the narrative, being so interwoven with the events as not to admit of a separation. I shall now give a more full and circumstantial description of each, in which, if some things should happen to be repeated, the greater part will be found new.
