uplift, been deeply but not maturely dissected. Vertical erosion 

 has been extremely active ; but lateral erosion has not pro- 

 gressed very far. The country, therefore, is broken into a 

 series of narrow and steep valleys and sharp ridges. The prin- 

 cipal stream is the Yarra, which is here confined to a narrow 

 valley. The township of Warrandyte lies on the southern side 

 of the river ; and at its western end, Anderson's Creek enters 

 the Yarra from the south, while at the eastern end, Parson's 

 Gully joins the same main river. It is with the relations between 

 Anderson's Creek and Parson's Gully that this paper is con- 

 cerned ; and therefore some remarks on the directions and 

 positions of these valleys will be offered. 



Anderson's Creek rises a little to the north of Ringwood. It 

 consists here of two small creeks, which soon unite ; and the 

 resulting stream then runs in a direction a little west of north 

 until it ajDproaches the western head of Parson's Gully, when 

 it turns more to the west, and so continues until joined by 

 Harris's Gully from the south. It then runs northerly to the 

 Yarra. Although Anderson's Creek along its whole course is 

 essentially a young stream, this feature is more marked in that 

 portion between the turn near Parson's Gully and its junction 

 with Harris's Gully. The part mentioned is a deep gorge, and 

 contrasts with the other more open divisions of the valley. The 

 best view, perhaps, of the gorge (which it is convenient to refer 

 to as the " Anderson's Creek Gorge ") is from the southern end 

 of Fourth Hill, Avhere it is about 300 feet in depth. 



Parson's Gully is less in length than An4erson's Creek, as the 

 accompanying map indicates. Its head is forked, the eastern 

 prong of the fork being nearly a mile, while the western one is 

 about a quarter of a mile in length. The western prong is close 

 to the entrance to the Anderson's Creek Gorge. Parson's Gully 

 is a fairly broad, open valley, different from Anderson's Creek 

 Gorge, but resembling in general characters the upper and 

 lower parts of Anderson's Creek. The main road from Warran- 

 dyte to Ringwood runs through the valley of Parson's Guliy as 

 far as its western head, when it crosses into tlie valley of the 

 upper Anderson's Creek. Harris's Gully is similar in character 

 to Parson's Gully, but not so broad and well developed, although 

 of greater length. All the valleys mentioned are deeply trenched 

 in the peneplain.
