settling the Longitude were no less Numerous, and made as
often as the Sun and Moon came in play; so that it was impossible for any
Material error to creep into our reckoning in the intermediate times. In
justice to Mr. Green,* (* From this phrase, and from various remarks in
Mr. Green's own log, it would appear that Mr. Green was not very easy to
get on with; but there is no doubt of his unwearied zeal in astronomical
observations.) I must say that he was indefatigable in making and
calculating these observations, which otherwise must have taken up a
great deal of my time, which I could not at all times very well spare;
not only this, but by his instructions several of the petty Officers can
make and calculate these observations almost as well as himself. It is
only by such Means that this method of finding the Longitude at Sea can
be put into universal practice; a Method that we have generally found may
be depended upon within 1/2 a degree, which is a degree of Accuracy more
than sufficient for all Nautical purposes. Would Sea Officers once apply
themselves to the making and calculating these Observations they would
not find them so very difficult as they at first imagine, especially with
the Assistance of the Nautical Almanack and Astronomical Ephemeris, by
the help of which the Calculation for finding the Longitude takes up but
little more time than that of an Azimuth for finding the Variation of the
Compass; but unless this Ephemeris is Published for some time to come,
more than either one or 2 Years, it can never be of general use in long
Voyages, and in short Voyages it's not so much wanted.* (* The "Nautical
Almanac" was first published for 1767. That for 1770 was not published
until 1769; but it seems probable that Cook either had proof sheets, or
the manuscript calculations.) Without it the Calculations are Laborious
and discouraging to beginners, and such as are not well vers'd in these
kind of Calculations.
[Account of New South Wales Coast.]
SOME ACCOUNT OF NEW WALES.* (* Called in Admiralty and the Queen's Copy
New South Wales. It would appear that for this part of the voyage Mr.
Corner's copy was the first written, and that Cook's first idea was to
christen the country New Wales.)
In the Course of this Journal I have at different times made mention of
the Appearance or Aspect of the face of the Country, the Nature of the
Soil, its produce, etc. By the first it will appear that to the Southward
