boundary is of great importance in the pliysiography of the lake, 

 so that the above analogy will perhaps be found of assistance. 



At the northern extremity a series of gravel banks separate 

 the lake from Murray's Lagoon, which latter at present (February, 

 1907) is a dry area about one mile in diameter covered thickly 

 with rushes. Beyond this the country consists of a flat expanse 

 extending towards Breadalbane. The Divide between the Wollon- 

 dilly River system and the Lake George area is not well defined 

 and seems to lie just north of the main Southern Railway. 



On the eastern shore the lake outline is somewhat irregular. 

 Ondyong Point, Rocky Point, Currandooley Point and Native Dog 

 mark the spurs projecting from the Gourock Range into the lake 

 (Plate vii.). In broad valleys between these spurs lie the streams 

 which water Lake George; Murray's Creek (the name on the map, 

 Allianoyonyiga, one is not surprised to find unknown in the 

 district); Taylor's Creek at the foot of Governor's Hill, the most 

 prominent landmark round Lake George; Deep Creek and Turallo 

 Creek. It will be noticed that these creeks converge on the 

 locality known as Geary's Gap (vide stereogram). 



Reverting to the western shore, we are struck by the absolute 

 dissimilarit3\ Standing at the level of the lake we seem to be 

 confronted by a giant wall extending northwards for over twenty 

 miles from the Molonglo Plain. No broad valley breaks its con- 

 tinuity. Indeed, to one cycling along the foot of the Cullarin 

 Range, it seems unbroken by any definite gap, while for a large 

 part it presents a steep face 500 feet high to the lake. From 

 the opposite shore (Governor's Hill), however, one is able to see 

 a well defined gap about half-way along the western shore where 

 the old Southern Road crossed the Cullarin Range. This depres- 

 sion — Geary's Gap — was well known in the days before the rail- 

 way, but is now practically unused by travellers. Less than two 

 miles south of Geary's Gap a stream (Grove Creek) rushes down 

 to the lake. Contrast its course with that of Taylor's Creek on 

 the eastern shore. The latter stream flows through a broad 

 valley, a mile or two wide, scooped out of the granite, and shows 

 the even grade of a mature or senile type of river. The Grove
