These considerations, added to the state of our provisions, of which, at the reduced ration of three pounds of flour per man per week, we had but ten weeks remaining, determined me to proceed no farther westward with the main part of the expedition; but as the state of the greater part of our horses was such as absolutely to require some days’ rest and refreshment, before we attempted to return eastward, I considered that it would be acting best up to the spirit of my instructions to proceed forward myself with three men and horses, and as we should carry nothing with us but our provisions, we should be enabled to proceed with so much expedition, as to go as far and see as much in three days as would take the whole party at least seven to perform.

My object in thus proceeding farther was to get so far to the westward as to place beyond all question the impossibility of a river falling into the sea between Cape Otway and Cape Bernouilli.  In my opinion, the very nature of the country altogether precludes such a possibility, but I think my proceeding so far will be conclusive with those who have most strongly imbibed the conviction that a river enters the sea between the Capes in question, which was certainly an idea I also had entertained, and which nothing but the survey of a country, without either hills or permanent streams, could have destroyed.

I must observe as a remarkable feature in this singular country, that for the last fifty miles we have not seen a stone or pebble of any kind, save two, and they were taken out of the maws of two emus.  I am now firmly persuaded that there are no eminent grounds in this part of the country, until these low sandy hills [Note:  From Encounter Bay to this slight projection (Cape Bernouilli), the coast is little else than a bank of sand, with a few hummocks on the top, partially covered with small vegetation, nor could any thing in the interior country be distinguished above the bank.  Flinder’s Voy.  Vol.  I. p. 197.] which bound the south-western coast-line are reached; and these, in my judgment, are the only barriers which prevent the ocean from extending its empire over a country which was probably once under its dominion.

July 6.—­A fine and pleasant morning; one of the horses was found dead, the greater part of the others in a very weakly state.

July 7.—­At eight o’clock, taking with me three men, I proceeded to follow the course of the stream; I attempted in the first instance to keep away from the banks, but was soon obliged to join them, as the morasses extended outwards and intersected my proposed course in almost every direction.  About three miles and a half from the tent, a large arm extended from the north bank to a considerable distance on that side; the banks continually getting lower, and before we had gone six miles it was evident that the channel of the stream was only the bed of a lagoon, the current now being imperceptible, with small gum trees growing in the middle.  Three
