Embark in this voyage, in order
to make drawings and paintings of such places in the countries we should
touch at, as might be proper to give a more perfect, idea thereof, than
could be formed from written descriptions only.
And it being thought of public utility, that some person skilled in natural
history, should be engaged to accompany me in this voyage, the parliament
granted an ample sum for the purpose, and Mr John Reinhold Forster, with
his son, were pitched upon for this employment.[15]
The Board of Longitude agreed with Mr William Wales and Mr William Bayley,
to make astronomical observations; the former on board the Resolution, and
the latter on board the Adventure. The great improvements which astronomy
and navigation have met with from the many interesting observations they
have made, would have done honour to any person whose reputation for
mathematical knowledge was not so well known as theirs.
The same Board furnished them with the best instruments, for making both
astronomical and nautical observations and experiments; and likewise with
four time-pieces, or watch machines; three made by Mr Arnold, and one made
by Mr Kendal on Mr Harrison's principles. A particular account of the going
of these watches, as also the astronomical and nautical observations made
by the astronomers, has been before the public, by order of the Board of
Longitude, under the inspection of Mr Wales.[16]
Besides the obligation I was under to this gentleman for communicating to
me the observations he made, from time to time, during the voyage, I have
since been indebted to him for the perusal of his journal, with leave to
take from it whatever I thought might contribute to the improvement of this
work.
For the convenience of the generality of readers, I have reduced the time
from the nautical to the civil computation, so that whenever the terms A.M.
and P.M. are used, the former signifies the forenoon, and the latter the
afternoon of the same day.
In all the courses, bearings, &c., the variation of the compass is allowed,
unless the contrary is expressed. And now it may be necessary to say, that,
as I am on the point of sailing on a third expedition, I leave this account
of my last voyage in the hands of some friends, who, in my absence, have
kindly accepted the office of correcting the press for me; who are pleased
to think that what I have here to relate is better to be given in my own
words, than in the words of another person; especially as it is a work
designed for information, and not merely for amusement; in which, it is
their opinion, that candour and fidelity will counter-balance the want of
ornament.[17]
