to adopt that mode of reaching the Strait:

And whereas, although that specific object was successfully achieved by
the survey of Raine Island Passage, and by the erection of a durable
beacon there to render it the more accessible, yet it appears that much
is still to be done in those seas in order to make the approach to the
Strait more secure and certain, as well as to afford the choice of
another entrance farther to the northward in case of vessels overshooting
the latitude of Raine Island by stress of wind, or current:

We have, therefore, thought proper to appoint you to the command of the
Rattlesnake, for the purpose of carrying out these objects; and you are
here by required and directed, when that ship is in every respect ready
for sea, to proceed in her to Madeira for the verification of your
chronometers--from thence to Simon's Bay at the Cape of Good Hope, for a
supply of water, and to land the 50,000 pounds you have been ordered to
convey to that colony; then to make the best of your way to the
Mauritius, to land the treasure (15,000 pounds) entrusted to your charge
for that island; and having so done, to proceed to King George Sound for
the purpose of carrying its exact meridian distance to Sydney, where you
will lose no time in preparing for the execution of the important service
entrusted to you.

The several objects of that service have been drawn up under our
direction by our Hydrographer; but notwithstanding the order in which
they are placed, we leave to your own discretion the several periods of
their performance, and likewise the times of your return to Sydney to
revictual and refit--being satisfied that your zeal in pushing forward
the survey will never outstrip your attention to the health and comfort
of your crew.

You will take the Bramble and her tender, the Castlereagh, under your
orders, and employ them in those places which require vessels of a
lighter draft of water than the Rattlesnake. They are to be attached as
tenders to the Rattlesnake, and to be manned from that ship; and such of
the present crew of the Bramble as may have served five years
continuously, and volunteer to remain on the surveying service in
Australia, are to be entered in the Rattlesnake under the provisions of
the Act of Parliament. The books of the Bramble are to be closed, and she
is to be considered as no longer in commission; and you are here by
authorised, after being joined by her and by the Castlere
