This evening, by moonlight, I conducted a dray, carrying two platforms, to the place where the narrow channel, feeding the swamp, could be passed without our meeting beyond any other impediment to the drays. The sleepers used for this purpose were made of pine (CALLITRIS PYRAMIDALIS), found half a mile back from our camp. They were fourteen feet long, two feet wide, being composed of cross-pieces, two feet long, fixed at each end between two sleepers, so that they somewhat resembled a wooden railway. These, when laid at the proper distance apart to carry both wheels, were bedded on the soft earth, and the interval between was filled to a level with them, by layers of polygonum and long grass, alternate with earth, forming together a mass of sufficient resistance to support the feet of the draught oxen. The whole formed a compact bridge or gangway. Thermometer at sunrise, 51 deg.; at noon, 95 deg.; at 4 P. M., 107 deg.; at 9, 70 deg.;--with wet bulb, 61 deg.. 13TH MARCH.--The party once more moved onward, and the drays trundled across the swampy arm by means of our bridge, which, even in the event of an accession of water there, might have proved serviceable on our return. Three miles beyond it we had to ford the Narran, passing over a gravelly bottom to the eastern bank, and encamping there. The drays were slow in arriving at this ford and camp, as the ground was soft and hollow, but by sunset all had crossed, and our camp established on the Narran. Thermometer at sunrise, 71 deg.; at noon, 100 deg.; at 4 P. M., 100 deg.; at 9, 71 deg.;--with wet bulb, 65 deg.. The height of this camp above the sea, according to ten registered observations, is 487 feet.
