The hounds found a large kangaroo almost immediately upon throwing off, and went away with him in good earnest. There was a burning scent, and from the nature of the country, over which we went for some distance without a check, the riding was really desperate. The country was thickly wooded, with open spaces here and there, in which fallen trees lay half hidden by long grass. Riding to the hounds was therefore as necessary as dangerous, for once out of sight it was almost impossible to overtake or fall in with them. Most of the field rode boldly and well, yet I remarked one or two casualties: early in the run, a gentleman was swept off his horse by the projecting branch of a tree, under which he was going at a reckless pace, and another had his hat perforated immediately above the crown of his head. Yet notwithstanding the annoyance of ferrying our horses across the Derwent, we returned to Hobart, very much pleased with the day's sport.* (*Footnote. In the first volume of the Tasmanian Journal, will be found an animated description of Kangaroo-hunting with these hounds, by the Honourable H. Elliot, who mentions that on one occasion a large kangaroo gave them a run of eighteen miles.) WHITE KANGAROO. In a gentleman's house there, I saw for the first time, a specimen of an Albino or white variety of kangaroo, Halmaturus bennettii.* Another object that interested me greatly was a quarry of travertine limestone, in the neighbourhood of Hobart, where I saw the impression** of leaves of plants, not in existence at present, and of a few shells of ancient species. (*Footnote. One of this rare kind, was presented by Sir John Franklin to her Majesty, in whose menagerie at Windsor it died, and was sent afterwards to the British Museum, where it now may be seen.) (**Footnote. Drawings of these impressions, together with the shells will be found in Count Strzelecki's scientific work.) SAIL FROM HOBART. We sailed from Hobart on the 19th of July and carried a strong fair wind to within a few days' sail of Sydney, when we experienced a current that set us 40 miles South-East in 24 hours; this was the more extraordinary as we did not feel it before, and scarcely afterwards; and our course being parallel to the shore, was not likely to have brought us suddenly within the influence of the currents said to prevail along the coast. The ship's position was 40 miles east of Jervis Bay when we first met it. July 24.
