son's Creek on the western side of the goldfield area, run 

 approximately parallel to one another. Fifth Hill, a high point 

 on the old peneplain at the entrance of Anderson's Creek Gorge, 

 is about 270 feet above the bed of tke stream. The western 

 head of Parson's Gully is separated from the gorge by a low 

 ridge, the latter being about 170 feet below the top of Fifth Hill, 

 and is therefore about 100 feet above the bed of tlie 

 Anderson's Creek Gorge. This ridge is continued as a shelf in 

 Anderson's Creek valley, above the gorge, and also in Parson's 

 Gully, on the eastern side of the latter valley. In this shelf 

 Anderson's Creek has cut a narrow, steep valley ; and Parson's 

 Gully and its tributaries have also somewhat dissected it. The 

 connecting low ridge itself has practically not been cut into. 



All these facts seem to point to the following conclusions : — 

 At the uplift of the peneplain, the natural drainage lines would 

 appear to have been along Harris's Gully and its continuation 

 (the lower part of Anderson's Creek), on the western side ; and 

 the upper part of Anderson's Creek and its continuation (the 

 present Parson's Gully) on the eastern side. The harder ground 

 between would be avoided as far as possible. The two streams 

 would be indejDendent of one another. Tributaries on each side 

 of both streams would, of course, be formed as the main streams 

 eroded their channels. One of such tributaries of Harris's Gully 

 apparently flowed westerly from the divide between the two 

 main streams along the course now occupied by the lower part 

 of the Anderson's Creek Gorge. This tributary would have 

 difficulty in cutting through the hard rocks of the goldfield, but 

 its grade would be steep, and this, aided by some faulting which 

 has probably taken place along part of the line of its valley, 

 would cause rapid vertical erosion and form a deep gorge. 

 Gradually eating its way backward, this tributary appears to 

 have eventually reached the eastern main stream, and to have 

 captured its upper waters when the valley of this eastern main 

 stream was not lower than the reduced ridge previously referred 

 to close to the Ringwood Road. By this capture, the tributary 

 became the main stream of the district, the present Anderson's 

 Creek. Harris's Gully, which was formerly the main western 

 valley, became subordinate to the tributary, and the old eastern 

 stream was reduced to the present Parson's Gully, occupying
