project to the height that they do above the phiteau country 

 to the south. 



I can, however, at present assign no other cause to the pro- 

 minence of the Warramate Hills, which may therefore tenta- 

 tively be regarded as a gigantic (in comparison with others in 

 the Yarra Basin) monadnock. 



Subsequent research may determine that these hills are due 

 to strong faiilting of the adjacent country in times prior to the 

 formation of the Nillumbik Peneplain ; or they may for some 

 unknown reason be the residuals of one or more peneplains. 



More measurements and wider observations are necessary 

 before coming to any conclusions as to the existence of pene- 

 plains above the Nillumbik Peneplain, and below that sug- 

 gested by Prof. Skeats as on tlie tops of the dacite masses referred 

 to by him ; but it may be pointed out that the Morang Hills, 

 " Pinemont," Burt's and Croydon Hills, and the " Kopje " 

 appear to be at about the same height (somewhere about 100 

 feet) above the Nillumbik Peneplain. This strongly suggests 

 that another peneplain existed at this level. The height of the 

 Divide just to the east of Mt. Disappointment is about 1700 

 feet. The Warramate Hills are about 1400 feet. Connecting 

 these two points, a third possible peneplain below the tops of 

 the dacite rocks suggests itself. 



View-Points. 



A few remarks on these may not be out of place. All the 

 monadnocks mentioned, as would be expected, constitute ex- 

 cellent points for observation of the surrounding country. 

 Close to Melbourne, Sugar Loaf Hill offers a very fine pano- 

 ramic view. 



At Kangaroo Ground, in the basalt country. Garden Hill 

 occurs. This is on the main road to Christmas Hills, a little 

 east of where the latter road diverges from the Queenstown 

 road. This hill and the adjacent basalt are almost destitute 

 of trees, and as the basalt is well above the surrounding 

 country, an excellent view of the latter is obtained. There 

 is no interruption in any direction for many miles. It is from 

 here that the general charactei- of the Yarra Plateau is well seen.
