Il2 THE VICTOKIAM NATUKALIST. (Vol. xxlv. 



southerly source, it rises almost due east of the Camel's Hump, 

 then flows north for some five miles, closely hugging the foot of 

 the range ; then, after an easterly course for another five miles, it 

 turns south, skirting the Mt. VVilHam Range for about the same 

 distance ; this it leaves towards Springfield, about two miles east 

 of the town. It seems to me that Melbourne Hill, or some of its 

 associates, may be responsible for this somewhat remarkable 

 course, through having elevated the original land surface, and so 

 forced the stream over as close to the ranges as was possible. 



Musk Gully, a glen in the Dividing Range, about five miles 

 north-west of the town, was chosen for the field excursion of the 

 Teachers' Association. The road thither, after crossing the Deep 

 Creek, passes through some poorly timbered country coloured as 

 Newer Pliocene on the Geological Survey Quarter-Sheet No. 5, 

 S.W, Silurian is then met with. Pliocene again appears, in the 

 midst of which is a small patch of Volcanic, less than a quarter of 

 a mile in diameter, called on the map *' The Red Rise." I was 

 told that without any other indication the position of this patch 

 could always be told on the darkest night by the cold feeling 

 experienced when passing over it. Presently our road became 

 steeper, and outliers of the granite of the Dividing Range 

 appeared, and in another mile the summit of the range, which is 

 also the county boundary, was crossed close to the Big Hill 

 State school, the school being only a few yards on the Dalhousie 

 side of the Divide. After a brief spell here for lunch, we struck 

 into the bush, south of the school-house, and found it a veritable 

 tangle of young forest and granite rocks, some of the latter being 

 of immense size. At that time of the year few plants were 

 to be obtained in bloom. However, I was able to identify the 

 majority of those collected. The one plant which seemed to be 

 in its element in the granitic soil was Pulteruea daphnoides, of 

 which many fine specimens were seen. Styplielia humi/usa, 

 Kennedya monophylla, Clematis aristata, Indigojera australis, 

 and Platylobiurn obtusmigidum were a few of the plants noticed, 

 from which may be gathered the character of the vegetation. The 

 little Rat-tailed Fern, Aspleiiium flahellifolium, grew in the 

 crevices of the granite. Presently we found ourselves on the 

 edge of the Divide, looking down into the valley of Tea-tree 

 Creek, the steep slope a mass of huge granite rocks. Down this 

 we gradually worked our way towards the little stream, encounter- 

 ing a dense growth of young wattles towards the bottom. At 

 the stream a bhort halt was called, and attention directed to some 

 of the plants noticed. On the opposite bank, near the site of an 

 old saw-mill, grew a fine Manna Gum, Eucalyplua viminalis, in 

 full bloom ; a golden everlasting, Udichrysxim , sp., was in bloom 

 on the hillside. Following up the little stream, which was 

 bordered with Silver Wattles, apparently just ready to burst into
