Considering our situation in its different bearings, it struck me that the men who were to return to Wellington Valley with an account our our proceedings for the Governor's information, had been brought as far as prudence warranted. There was no fear of their going astray, as long as they had the river to guide them; but in the open country which we were to all appearance approaching, or amidst fields of reeds, they might wander from the track, and irrecoverably lose themselves. I determined, therefore, not to risk their safety, but to prepare my dispatches for Sydney, and I hoped most anxiously, that ere they were closed, all symptoms of disease would have terminated.

In the course of the day, however, Spencer, who was to return with Riley to Wellington Valley, became seriously indisposed, and I feared that he was attacked with dysentery. Indeed, I should have attributed his illness to our situation, but I did not notice any unusual moisture in the atmosphere, nor did any fogs rise from the river. I therefore the rather attributed it to exposure and change of diet, and treated him accordingly. To my satisfaction, when I visited the men late in the evening, I found a general improvement in the whole of them. Spencer was considerably relieved, and those of the party who had inflammation of the eyes no longer felt that painful irritation of which they had before complained. I determined, therefore, unless untoward circumstances should prevent it, to send Riley and his companion homewards, and to move the party without loss of time.

We had not seen any natives for many days, but a few passed the camp on the opposite side of the river on the evening of the 25th. They would not, however, come to us; but fled into the interior in great apparent alarm.

DEPARTURE OF TWO MEN FOR WELLINGTON.

On the morning of the 26th, the men were sufficiently recovered to pursue their journey. Riley and Spencer left us at an early hour; and about 7 a.m. we pursued a N.N.W. course along the great plain I have noticed, starting numberless quails, and many wild turkeys, by the way. Leaving that part of the river on which Mr. Hume and I had touched considerably to the left, we made for the point of a wood, projecting from the river line of trees into the plain. The ground under us was an alluvial deposit, and bore all the marks of frequent inundation.

The soil was yielding, blistered, and uneven; and the claws of cray-fish, together with numerous small shells, were every where collected in the hollows made by the subsiding of the waters, between broad belts of reeds and scrubs of polygonum.

CONSULTATION.

On gaining the point of the wood, we found an absolute check put to our further progress. We had been moving directly on the great body of the marsh, and from the wood it spread in boundless extent before us. It was evidently lower than the ground on which we stood; we had therefore, a complete view over the whole expanse; and there was a dreariness and desolation pervading the scene that strengthened as we gazed upon it. Under existing circumstances, it only remained for us either to skirt the reeds to the northward, or to turn in again upon the river; and as I considered it important to ascertain the direction of the Macquarie at so critical and interesting a point, I thought it better to adopt the latter measure. We, accordingly, made for the river, and pitched our tents, as at the last station, in the midst of reeds.

There were two points at this time, upon which I was extremely anxious. The first was as to the course of the river; the second, as to the extent of the marshes by which we had been checked, and the practicability of the country to the northward.

In advising with Mr. Hume, I proposed launching the boat, as the surest means of ascertaining the former, and he, on his part, most readily volunteered to examine the marshes, in any direction I should point out. It was therefore, arranged, that I should take two men, and a week's provision with me in the boat down the river; and that he should proceed with a like number of men on an excursion to the northward.
