Jan. 26.--I removed my camp to the reedy water-hole of yesterday, about five miles in the direction of west or west by north from our last encampment. Here I planted the last peach-stones, with which Mr. Newman, the present superintendent of the Botanic Garden in Hobart Town, had kindly provided me. It is, however, to be feared that the fires, which annually over-run the whole country, and particularly here, where the grass is rich and deep even to the water's edge, will not allow them to grow. To the creek on which we were encamped I gave the name of "Newman's Creek," in honour of Mr. Newman. It flows in a south-east and southerly course, and unites probably with West Hill Creek, on which we were encamped the day before, and with the large creek which we crossed on the 25th; both of which probably belong to the system of the Mackenzie. Mr. Calvert and Charley accompanied me in an excursion to the W.N.W., but, having crossed some ridges and coming to scrub, we took a direction to the northward. Fine Bastard-box flats and Ironbark slopes occupy the upper part of Newman's Creek. On the ridges, we observed Persoonia with long falcate leaves; the grass-tree (Xanthorrhaea); the rusty gum, and the Melaleuca of Mount Stewart. Having ascended the sandstone ridge at the head of Newman's Creek, we found ourselves on a table land out of which rose the peaks for which we were steering, and from which we were separated by fine downs, plains, and a lightly timbered country, with belts of narrow-leaved Ironbark growing on a sandy soil. On one of the plains quartzite cropped out; and silex and fossil wood lay scattered over the rich black soil: the latter broke readily, like asbestos, into the finest filaments, much resembling the fossil wood of Van Diemen's Land. It is difficult to describe the impressions which the range of noble peaks, rising suddenly out of a comparatively level country, made upon us. We had travelled so much in a monotonous forest land, with only now and then a glimpse of distant ranges through the occasional clearings in the dismal scrub, that any change was cheering. Here an entirely open country--covered with grass, and apparently unbounded to the westward; now ascending, first, in fine ranges, and forming a succession of almost isolated, gigantic, conical, and dome-topped mountains, which seemed to rest with a flat unbroken base on the plain below--was spread before our delighted eyes. The sudden alteration of the scene, therefore, inspired us with feelings that I cannot attempt to describe. Proceeding onwards we passed some water-holes; but, farther on, the water failed, except here and there in a few pools, in the creeks coming from the range, that had been filled by the last thunder-showers. These pools were generally lined with patches of a narrow-leaved tea tree; and were full of basaltic pebbles.
