ascended the nearest summit on the right, and from it beheld a prospect most cheering, after our toils amid rocky ravines. On the westward, the rocky range seemed to terminate abruptly towards the north, in an elevated point, which seemed to command an extensive view over the unknown W. and N.W. Out of that region two isolated mountain masses arose from an open country, and were clothed with open forests to their summits. Further eastward, masses of mountain in the extreme distance appeared covered, also, with open forests, and presented finely rounded outlines, not likely to impede our passage, in any direction. But towards the N.W. our view was not so extensive; like the uncertain future, it still lay hid. The retrospect was very extensive, including Mount Faraday in the extreme distance, and which thus afforded me a valuable back angle for the correction of our longitude from any errors of detailed survey. The lofty mass of Buckland's Table Land still overlooked all from the E., and I could here again intersect its three principal points. The view back to the Pass was very fine, for the rocks and wood were so blended on the bold summits, as to present sublime studies for the artist. Far to the westward, an interior line of cliffy range resembled a sea beach, presenting a crescent, concave on that side, apparently the limit to the basin of the Nogoa, and the dividing range between eastern and western waters. Our Pass seemed to be the only outlet through the labyrinths behind us. Even the open plains beyond them were visible in a yellow streak above the precipices. Far beyond these plains, Mount Faraday was distinctly visible, on the horizon of the landscape. Thermometer, at sunrise, 29 deg.; at 9 P.M., 43 deg.. (LI.) 1234 feet above the sea. 18TH JULY.--By retracing our horses' footsteps, the carts were soon brought to the base of the same hill; deep gullies in the clay having obliged us to pass close under it, and, indeed, to cross two of its elevated extremities. We found the country beyond, in a N.W. direction, tolerably open, and we encamped in a valley containing abundance of grass, and near to our camp, water was found in a chain of ponds descending to the eastward. A new SUAEDA, with short leaves, and the habit of a dwarf Tamarisk, was found this day.[*] Latitude, 24 deg. 6' 47" S. Thermometer, at sunrise, 31 deg.; at noon, 65 deg.; at 4 P.M., 69 deg.; at 9, 44 deg.. (LII.) [* S. TAMARISCINA (Lindl. MS.); fruticosa, ramosissima, foliis brevibus cylindraceis imbricatis obtusissimis, axillis lanatis, floribus solitariis sessilibus.]
