“To ascertain this point is worthy of a practical experiment in a geographical point of view, as the knowledge of the direction that mountains and rivers take, the bones and blood vessels of bodies terrestrial give us at least a picture of the body of that skeleton.  To these Mr. Sturt will no doubt direct his particular attention, as constituting the main object of such an expedition, and these, with the great features of the country, its principal productions in the animal and vegetable part of the creation, the state and condition of the original inhabitants, will render a great service to the geography of the southern part of Australia.”

On this memorandum the Secretary of State observes, in a private letter to Captain Grey, that came to hand before the receipt of Lord Stanley’s public despatch:—­

“In considering Sir John Barrow’s memorandum, enclosed in my public despatch, you will see that a strong opinion is expressed against ascending the Darling in the first instance, and in favour of making a direct northerly course from Adelaide to Mount Arden.  I do not wish this to be taken as an absolute injunction, because I am aware that there may be local causes why the apparently circuitous route may after all be the easiest for the transport of provisions, and may really facilitate the objects of the expedition.  In like manner I do not wish to be understood as absolutely prohibiting a return by Moreton Bay, extensive as that deviation would be, if it should turn out that the exploration of the mountain chain led the party so far to the eastward as to be able to reach that point by a route previously known to Captain Sturt or to Major Mitchell, more easily than they could return on their steps down the Darling.  What Captain Sturt will understand as absolutely prohibited, is any attempt to conduct his party through the tropical regions to the northward, so as to reach the mouths of any of the great rivers.  The present expedition will be limited in its object, to ascertaining the existence and the character of a supposed chain of hills, or a succession of separate hills, trending down from N.E. to S.W., and forming a great natural division of the continent; to examining what rivers take their source in those mountains, and what appears to be their course; to the general lie of the country to the N.W. of the supposed chain; and to the character of the soil and forests, as far as can be ascertained by such an investigation as shall not draw the party away from their resources, and shall make the south the constant base of their operations.”

I presume, from the tenor of Sir John Barrow’s memorandum, that he was not fully aware of the insurmountable difficulties the course he recommends presented.  Valuing his judgment as I did on such an occasion, and anxious as I was to act on the suggestions of the Secretary of State, the strongest grounds could alone have made me pursue a course different to that which had been recommended to me.  Certainly the fear
