The botany is not mucli varied, the only novelties being 

 a species of Kennedia, with one of Calythrix, Callicoma, and 

 Elichrysum. It is worthy of remark, that on the upper 

 regions of these mountains, the common productions of the 

 South-head Road and Port Jackson predominate. 



Aug. Mh. — Weather cold and bleak. At eight o'clock, 

 Capt. Logan proceeded to the base of Mount Hooker, for 

 the purpose of examining the Pass, (since called St. George's,) 

 which we observed there yesterday, when upon Mount Lind- 

 say. He returned at six in the evening, having advanced 

 six miles to the south through the Pass, and reports that the 

 path is accessible, though it requires some clearing. It may 

 be approached either by Glen Lyon, or by the base of Mount 

 Lindsay, and it will soon be the great entrance to the Shoal 

 Bay Country, connecting those tracts with the Moreton Bay 

 Country, which promises to be, ere long, the emporium of 

 Australia. We took the height of Mount Lindsay above the 

 valley, by trigonometrical survey, which gave an elevation of 

 4755 feet, and allowing that the valley itself, as calculated 

 by the barometrical experiments, was 900 feet above the level 

 of the sea, an altitude of 5655 feet will thus belong to the 

 mountain ; while Mount Hooker may be estimated at 4000 

 feet, and Mount Clanmorris at 5000. 



The latitude was 28° 15' 21" South, and allowing the centre 

 of Mount Lindsay to be three miles south of the situation of 

 our tent, its true position may be reckoned at 28° 18' 21" 

 South, long. 152° 0' 06". 



Aug. 5th. — The morning was clear and calm, and we 

 started at the usual hour. Our course being altered from 

 that of yesterday, we were led into a ravine, formed by the 

 River Logan, between Mount Clanmorris and Lloyd's Hill, 

 through which we found it impossible to effect a passage. 

 Capt. Logan and Mr. Cunningham having got through on 

 foot, I returned with the cattle by the way that we had gone 

 on the 2d, and rejoined them on the banks of the river, which 

 here expands into a fine stream, and in which, a few miles 

 farther on, there is no current whatever, the whole percolat- 

 ing through the gravelly bottom. After crossing the river.
