2D OCTOBER.--At 6 A.M. the thermometer gave a temperature of 59 deg.. The height above the sea was 1081 feet. In tracing back our old track, I sent Corporal Graham to examine a part of the river channel likely to contain water, and the report of his pistol some time after in the woods, welcomer than sweetest music to our ears just then, guided us to the spot, where he had found a small pond containing enough for all our wants. For the men, having no more tea or sugar, a good drink was all that was required; the poor fellows prepared my tea not the less assiduously, although I could have had but little comfort in drinking it under such circumstances, without endeavouring to share what was almost indivisible. We this day performed a long journey, reaching our former bivouac, of the 16th September, on Graham's creek, at an early hour. Three emus were seen feeding close by; but, although several attempts were made to get near them, with a horse stalking, we could not kill any of them. 3D OCTOBER.--Soon after we had quitted our bivouac, the emus were again seen on the plains. I could not deny the men the opportunity thus afforded them of obtaining some food; for, although they concealed their hunger from me, I knew they were living on bread and water. Graham succeeded in wounding one of the birds, which, nevertheless, escaped. He then chased a female followed by about a dozen young ones, towards us, when we caught three. It had occurred to me this morning, to mark and number the bivouacs we had occupied thus far, for the purpose of future reference, when any other party might proceed, or be sent again, into this country. I had, therefore, cut the number 73 on a tree at this bivouac of 3d October, under the initials N.S.W. We pursued a straight course over the downs, east by compass, until we joined our old route along the water-course, from our camp near the gap, and this brought us back, at an early hour to that spot, where I marked a tree with the figures 72. 4TH OCTOBER.--We recrossed the brigalow range, (where the temperature, at 9 A.M., was 79 deg.,) and alighted by the pond at the junction of the Nivelle and Nive; near where we had passed the night of the 12th September. This day we again saw the CALLITRIS; a tree so characteristic of sandy soils, but of which we had not observed a single specimen in the extensive country beyond. Marked 71 on a tree.
