22D MARCH.--Gave the party a day's rest, prayers being read by the surgeon, as was usual whenever circumstances admitted of our halting on Sunday. The bed of the Narran presented in several places the denuded rock, which seems the basis of all the soil and gravel of the country. At one place irregular concretions of milk-white quartz, cemented by a ferruginous basis, was predominant; at another, the rough surface of compact felspar weathering white presented merely the cavities in which large rounded pebbles had been imbedded, until the partial decomposition of the felspar, under the river floods, had exposed them once more to the action of water. The force of those waters, however, had not been sufficient to cut a channel through very soft rocks extending right across their course--a circumstance rather characteristic, perhaps, of a river like the Narran, watering a nearly level country, and terminating in a swamp. Thermometer at sunrise, 53 deg.; at noon, 95 deg.; at 4 P. M., 98 deg.; at 9, 72 deg.;--with wet bulb, 66 deg.. Height above the sea, 515 feet, from eight observations. 23RD MARCH.--All hands were bent on an early start this morning, and, soon after seven, the party moved off. We crossed much grassy land, almost approaching to the character of scrub as to bushes; but we pursued a tolerably straight course to the N.W., until we again made the Narran at 81/2 miles. Various new plants attracted my attention this day, especially a beautiful Loranthus on the rosewood Acacia, and a small bush bearing a green pod resembling a small capsicum in shape. Among the sedges by the river we found the KYLLINGA MONOCEPHALA; and, on the rich black clayed soil near it, a species of bindweed out of flower, with large sagittate leaves: in the scrubs back from the river, grew a small bush, about four feet high, which has been considered either a variety of Brown's SANTALUM OBLONGATUM, or a new species distinguished by its narrow sharp-pointed leaves. The LORANTHUS LINEARI. FOLIUS was growing on the rosewood Acacia, and the branches of Eucalypti were inhabited by the parasitical ORANGE LORANTH.[*] Lat., 29 deg.1 0' 6" S. Therm. at sunrise, 51 deg.; at noon, 95 deg.; at 4 P. M., 99 deg.; at 9, 70 deg.;--wet bulb, 63 deg.. [* L. AURANTIACUS (All. Cunn.
