Physiography of Western Portion Of-oailnyoloiig. 85 



A. W. Hewitt's "Devonian Rocks of North Gippsland, will 

 be found most interesting information on the eastern and 

 western sources of the Snowy River. The enormous erosion 

 of the middle portion of the Snowy Valley is plainly seen 

 from Turnback Mountain on the old Maneroo road, or from 

 the summit of Mount Tingiringy, near the New South 

 Wales border. The landscape looking north from the latter 

 mountain is perhaps the finest mountain scene in Australia — 

 it is certainly one of grandeur. To the north, beyond the 

 deep gorge formed by the Snow}' River, rise a series of bold 

 wooded mountains, the lower spurs of the latter almost 

 invisible in the soft haze of the deeper portions of the valley. 

 Beyond the wooded mountain ranges appear in silhouette 

 tile rugged porphyry heights of Mount Cobberas, the coned 

 peak of Mount Pilot, and rising tier aliove tier the bold 

 granite knobs of the Snowy Kosciusko ]3lateau. Away to the 

 right stretches the fine open and undulating downs of the 

 Maneroo plateau, relieved here and there by minor ridges 

 covered with timber, or along the creeks by belts of the 

 Snowy Rivei- pine. While to the south the bold outlines of 

 Mount Delegate, Mount Bowen, and the coast range, mark 

 the sites of rock masses which have longest i-esisted the 

 effects of subaerial denudation and the borderland between 

 the jungle country of Croajingolong and the south-western 

 extension of the Manei'oo table land. 



As the Snowy drains the highest elevations in Australia, 

 and runs almost due south from their high altitudes to the 

 coast line, its cour.se is almost torrential throughout, except 

 where it enters the rich alluvial flats of Orbo.st, where the 

 stream becomes sluggish. To enter into a minute description 

 of the salient points in the topography of the eastern water- 

 shed area, would form tlie subject matter for an interesting- 

 paper, so varied is the surface configuration. The principal 

 eastern source afluents drain the extensive Maneroo plateau 

 outside the boundaiy of the colony, and need not bereferi-ed 

 to. The streams within the county compiise the Deddick 

 or Jingallala and its tributaiies, the Tingiiingy, Dellicknora, 

 Cabanandra, and Bonaug. There are several others which, 

 ultimately flowing into the parent stream in New South 

 Wales, rise in the coast range, such as the Delegate, Bendoc, 

 Queensborough. Below the junction of the Deddick, several 

 torrential streams enter the Snowy from the east, tlieir 

 coui'ses mainly south-we.sterly, such as Mountain Creek, the 

 Broadbent, Yalma, and Rodgers Rivers. Below the Orbost
