TERRA AUSTRALIS. 
George's Sound, and carrying on your survey from thence to the 
eastward . 
You are to repair from time to time, when the season will no 
longer admit of your carrying on the survey, to Sydney Cove ; from 
whence your are to return in the execution of these instructions, so 
soon as circumstances will enable you so to do. 
You are to be very diligent in your examination of the said coast, 
and to take particular care to insert in your journal every circum- 
stance that may be useful to a full and complete knowledge thereof, 
noting the winds and weather which usually prevail there at different 
seasons of the year, the productions and comparative fertility of the 
soil, and the manners and customs of the inhabitants of such parts as 
you may be able to explore ; fixing in all cases, when in your power, 
the true positions both in latitude and longitude of remarkable head 
lands, bays, and harbours, by astronomical observations, and noting 
- the variation of the needle, and the right direction and course of the 
tides and currents,, as well as the perpendicular height of the tides; 
and in case, during your survey, any river should be discovered, you 
are either to proceed yourself in the tender, or to direct her com- 
mander to enter it, and proceed as far up as circumstances will permit ; 
carefully laying down the course and the banks thereof, and noting 
the soundings, going on shore as often as it shall appear probable that 
any considerable variation has taken place either in the productions 
of the soil or the customs of the inhabitants ; examining the country 
as far inland as shall be thought prudent to venture with the small 
number of persons who can be spared from the charge of the vessel, 
wherever there appears to be a probability of discovering any thing 
useful to the commerce or manufactures of the United Kingdom. 
When you shall have completely examined the whole of the 
coast from Bass's Strait to King George the third's Harbour,you are, 
at such times as may be most suitable for the purpose, (which may be 
seen on a reference to Mr. Dalrymple's memoir, an extract of which 
accompanies this,) to proceed to and explore the north-xvest coast of 
New Holland, where, from the extreme height of the tides observed 
by Dampier, it is probable that valuable harbours may be discovered.
