cut by a series of deep valleys into several spurs running south- 

 ward from the main ridge. The most westerly of these spurs 

 begins at the Camel's Hump and lies between the Turritable 

 Creek to the west and the Willimigongong Creek to the east ; 

 it may be called the Upper Macedon Spur, as that village is 

 situated upon it. The second spur is on the eastern side of the 

 Willimigongong, and its most conspicuous feature is its southern 

 shoulder. Mount Towrong (2820 feet) ; it may be called the 

 Towrong Spur, Eastward again is the valley of Baringo Creek. 

 Then follows the third spur, which leaves the main ridge at the 

 height of 2720 feet at " Mahoney's Corner " and runs through 

 Cherokee's to Mount Robertson ; it may be called the Cherokee 

 Spur. The eastern side of this spur is formed by the " Running 

 Creek," a small stream which rises near Kerr's Mill, and flows 

 through a gap between Mount Teneriffe to the south and Mount 

 Charlie to the north, and joins the Bolinda Creek. These two 

 hills are capped by Kerrie conglomerates and geologically are not 

 part of the Macedon group. To the north of them is Mount 

 Eliza, which forms the eastern end of tlie main ridge. 



On the plain to the north of the main ridge are several hills, 

 which belong geologically to Mount Macedon. They are the 

 Hanging Rock ; Dryden's Hill or the Jim-Jim, north-west of 

 Newham ; Brock's Monument, north-east of the eastern shoulder; 

 and several unnamed hillocks. The ridge south of Mount 

 William is mapped as " Hypogean Trap " on the Geological 

 Survey maps, but the rock in question has no connection with 

 the Macedon series. 



The general topography of the mountain, with the nomencla- 

 ture adopted, is shown on the accompanying shetch map (Fig. 1). 

 The nomenclature of the peaks is somewhat confused, but I have 

 adopted the names used locally. The Camel's Hump is marked 

 as Mount Diogenes on the parish map and on the Geological 

 Survey map, whereas on the Index map of tlie Geological Survey 

 the name Alexander's Crown is apparently given to this peak. 

 The Hanging Rock is called Mount Diogenes on the parish map 

 of Newham, Dryden's Rock and the Hanging Rock being given 

 as synonyms. The name Dryden's Hill is now generally accepted 

 for the ridge to the north-west of Newham Hotel ; it is thus 

 marked in the county map of Dalhousie. This hill is also 

 known as the Jim-Jim.
