westerly to Trawool, where it again turns north to the Murray. It 

 is evident from its varied course (Fig. 5) that it has suffered many 

 changes, since its present valley is far from .being the harmoniously 

 branched whole that follows from the uninterrupted development of 

 a large river through a long period of time. (See Fig. 5). As 

 stated, the upper Goulburn has attracted much attention. 



Skeats (Records A.A.A.S., Brisbane, 1909), suggests that the 

 divides have been determined by differential denudation, being 

 mainly outlined by plutonic masses. Jutson (Proc. Roy. See, Vic, 

 1911) agrees and believes that the Goulburn has enlarged its terri- 

 tory at the expense of the Yarra and Thompson Rivers. Gregory 

 (Geog. of Vict.) regards the middle Goulburn as a lately developed 

 stream that has captured the King Parrot, Yea and Acheron Rivers 

 from the Yarra valley. Taylor (Physiography Eastern Australia) 

 suggests that the old divide ran from Torbreck to Howitt. 



In the absence of reliable topographical maps, and in view of the 

 large area concerned, combined with the rugged and unsettled 

 nature of most of it, it is very difficult to arrive at the truth of the 

 matter. Certainly most maps are misleading, the hachures usually 

 failing to distinguish between comparatively low hills and high 

 resistant mountains. Important ridges are sometimes left out of 

 the maps altogether. In support of the idea that the Goulburn 

 originally flowed north through Barjarg Gap (see Fig. 10), the 

 following considerations may be advanced : — 



(i.) Such a course would bring the Goulburn into a harmonious 

 parallelism with other Vict, rivers draining to the Murray. 



(ii.) The Barjarg Gap is itself evidence of a highly significant 

 nature. 



(iii.) Other gaps such as Brack's Gap (see Fig. 1) also occur, an<i 

 may matk the old valley. 



(iv.) There is a definite north and south mass of highlands which 

 would appear to have been the old western boundary of this valley. 

 These are the Cerberean Range, continued north through the Puzzl© 

 Range to the Strathbogies. Through these highlands the only exit 

 westerly is by the narrow valley at the Sugarloaf, west of Darling- 

 ford. (See Kiii-. •").}
