The morning was rather cool, with clouds and distant thunder. We now proceeded in a northerly direction until we were impeded by scrub, about three miles from the camp. Through this we cut our way, keeping as closely in the northern direction as the openings would allow. At length the wheels of one of the carts, and the axle of another, became unserviceable, and could not be repaired, unless we halted for two days. As they could only be dragged a few miles further, I went forward as soon as we got clear of the scrubs, which extended three miles, in search of water for an encampment. I came upon a slight hollow and followed it down, but it disappeared on a level plain, bounded on each side by rising grounds. One dry pond encouraged my hopes, and I continued my search along a narrow flat, where the grass had been recently on fire. From this point, and while pursuing a kangaroo, I came upon a well marked watercourse with deep holes, but all these were dry. Tracing the line of these holes downwards to where the other flat united with it I found, exactly in the point of junction, as I had reason to expect, a deep pool of water. Once more therefore we could encamp, especially as two very large ponds on a rocky bed were found a little lower than that water first discovered. This element was daily becoming more precious in our estimation, and I had reason to be very anxious about it, on account of Mr. Finch, who was following in our track. The spot on which we encamped was covered with rich grass, and enclosed by shady casuarinae and thick brush. The prospect of two days' repose for the cattle on that verdure, and under these shades, was most refreshing to us all. It was, indeed, a charming spot, enlivened by numbers of pigeons, and the songs of little birds, in strange, but very pleasing notes.
Here I again remarked that among these casuarinae scrubs the eucalyptus, so common in the colony, was only to be seen near water; so that its white shining bark and gnarled branches, while they reminded us of home at Sydney, also marked out the spots for fixing our nightly home in the bush.
EXCESSIVE HEAT AND DROUGHT.
January 7.
The night had been unusually hot, the thermometer having stood at 90 degrees, and there had not been a breath of wind. Few of the men had slept. Thus even night, which had previously afforded us some protection from our great enemy, the heat, no longer relieved us from its effects; and this incessant high temperature which weakened the cattle, dried up the waters, destroyed our wheels, and nourished the fires that covered the country with smoke, made humidity appear to us the very essence of existence, and water almost an object of adoration. No disciple of Zoroaster could have made proselytes of us. The thermometer ranged from 96 to 101 degrees during the day, and during the last five nights had stood as high as 90 degrees between sunset and sunrise. From the time the party left Sydney rain had fallen on only one day. We left each friendly waterhole in the greatest uncertainty whether we should ever drink again, and it may be imagined with what interest, under such circumstances, I watched the progress of a cloudy sky. It was not uncommon for the heavens to be overcast, but the clouds seemed to consist more of smoke than moist vapour. The wind, from the time of our first arrival in the country, had blown from the north or north-west, and the bent of trees, at all exposed, showed that these were the prevailing winds.
DESCRIPTION OF THE WOODS.
The country when seen from an eminence appeared to be very generally wooded, but the lower parts were perfectly clear, or thinly strewed with bushes, and slender trees, chiefly varieties of acacia. The principal wood consisted of casuarinae which grew in thick clumps, or scrubs, and very much impeded, as has already been stated, our progress in any given direction. I found that these scrubs of casuarinae grew generally on rising grounds, and chiefly on their northern or eastern slopes. We saw little of the callitris tribe, after we had crossed the first hill beyond our last camp on the Namoi. On the contrary, these casuarinae scrubs and grassy plains seemed to characterise the country to the westward and northward of the Nundewar range, as far, at least, as we had yet penetrated. The course of this chain of ponds appeared to be parallel to that on which we had previously encamped, 36 degrees North of West. A yellow, highly calcareous sandstone occurred in the bed and banks of this stream, forming a stratum from two or three feet in thickness, and in parts of the upper surface nodules of ironstone were embedded.
On examining our wheels, we found that the heat had damaged them very much, some of the spokes having shrunk more than an inch. The carpenter managed however to repair them this day.
January 8.
The morning was cool and pleasant, with a breeze from the west. We left the ponds (named Wheel Ponds) exactly at six A.M., and, after travelling a mile, entered a scrub through which we were compelled to cut a lane with axes, for three miles; when at length the wood opened, and some trees of that species of eucalyptus called box grew on the flats. At five miles from our camp I shot a kangaroo.
