The so-called Saddleback is one of the tor-mountains 

 eminently characteristic of the N.E. plateau of Tasmania, 

 which is the main divide for the river system in that part 

 of the State. Like its adjacent neighbour, Ben Nevis, it 

 rises from the southern edge of the plateau, though its spurs 

 running in that directioaa descend to the foot of the upland 

 and join with the ranges flanking the north bank of the 

 South Esk. The mountain takes the form of a short ridge 

 with an axis lyiucr about south-west — north-east, its 

 structure being like that of the other plateau-mountains, 

 diabase. The eastern face is precipitous, and towers over 

 the Ringarooma-Mathinna track, which passes it at an ele- 

 vation of about 2,200 feet, and not far from the base. 



The Crestline, though jagged and rough, has an un- 

 dulating aspect from distant, eastern points of view, and 

 is continuous with a spur which runs up from the foothills 

 In the valley of the South Esk, rising with a fairly regular 

 slope to a prominence, south of the summit, from which 

 there is a slightly ascending dip up to the top, which takes 

 the form of a flattish dome with rather an abrupt northern 

 descent to the plateau. 



The writer has sketched the aspect of the tor from 

 various eastern points, from none of which has it any ap- 

 pearance of a saddlebacked mountain ; nor could such a 

 hump-backed ridge take that form from any direction.
