For your farther information and guidance, you will receive herewith a paper marked A, which is a copy of one lately received by me from Earl Bathurst, His Majesty’s principal Secretary of State for the colonies, and which I am directed by his lordship to make the groundwork of my instructions to the officer whom I might think proper to select for, and entrust with the due execution of the services therein required.  And I therefore refer you for all farther instructions to the paper thus alluded to; persuaded you will do every thing in your power to comply with and execute, as far as your means will allow, the several orders and directions therein contained; communicating these instructions to the several persons employed with you on the expedition, in as far as they are severally concerned in making the observations and collections pointed out in the said instructions from the Secretary of State.

Sixth.—­It will of course be necessary in order to ascertain the exact distance and direction of your journies, whilst prosecuting your discoveries, that the country through which you travel shall be regularly chained and laid down upon a chart; but I leave it optional with yourself to do this either during your outward or homeward bound journey; and as it is expected that the Lachlan River will be found to empty itself into that part of the sea on the south-west coast of Australia, between Spencer’s Gulf and Cape Otway, it is hoped you will he able to make all the necessary discoveries, and return again to Bathurst considerably within five months; as the greatest distance from thence to that part of the coast, where the river is supposed to fall into it, cannot exceed six hundred miles.  It is also hoped and expected, that the Lachlan and Macquarie Rivers unite at some distant point from where Mr. Evans terminated his trace of the Lachlan River; and in case these two rivers are found to form a junction, the exact place of their confluence must be clearly and exactly ascertained in regard to latitude and longitude, and noted down accordingly.  The latitude and longitude of the junction of both or either of these rivers with the sea, or inland lake, must also be accurately ascertained and marked down in the chart to be made of your entire tour and discoveries.

Seventh.—­On your return from your journey to the sea-coast to Bathurst, you are to direct all the journals or other written documents belonging to, and curiosities collected by the several individuals composing the expedition, to be carefully sealed up with your own seal, and kept in that state until after you have made your report in writing to me at Sydney, of the result of the expedition.

Eighth.—­I have only to add, that I wish you to set out from Sydney on the present service, on Monday, the 31st of this present month, so as to arrive at Bathurst, on or before the 8th of the ensuing month.
