Highlands of Western Victoria. 273 



lines are the main roads across; the Divide. The Divide itse>lf 

 is indicated by the heavy broken line, and the fainter broken 

 lines mark the approximate limit of the slopes from each vol- 

 canic centre. A number of swsiimps are shown by the letter S. 

 The volcanic hills are as follows: — On the Divide: 1, Brown's 

 Hill; 2, Bankin's Hill; 3, Coghill's Hill, 1630 feet; 4, Mt. 

 Cavern, 1588; 5, Mt. Hollowback, 1842; 6, Mt. Pi^gah, 1771. 

 South of the Divide: 7, Mt. Blowhard, 1664 ; 8, McLean's Hill; 

 9, Morton's Hill; 10, Saddleback Hill, 1548; 11, Weatherboard 

 Hill, 1826 ; 16, Mt. Rowan. North of the Divide : 12, Tinkler's 

 Hill; 13, Webster's Hill; 14. Vaughain's Hill, 1611; 15, One 

 Mile Hill, 1443. 



The information is largely from Mr. Norman Taylor's Geologi- 

 cal Map of Learmonth. 



Fig. 3. Profile of the Divide in Ascot Gap, Granite and 

 Ordovician Ranges in the background shajded ; the numbers 

 have the same significance as in the preceding diagram. 

 Sketched from Mt. Blowhard. The level topped Ordovician 

 Ranges seen in the distance are partly west and partly east of 

 the Dean Gap, a few volcanic Hills in this Gap are shown. 



Fig. 4. Sketch of the Hills west and north-west from Mt. 

 Buninyong. The distances of several of the lulls are given under 

 their names. Distances from point to point are also shown. The 

 Serra Range is often visible as a more continuous line. 



Fig. 5. Diagram to illustrate the possible courses of the leads 

 south of the present Divide. indicates areas of Ordovician 

 rocks close to the surface ; G of granitic rocks. The interven- 

 ing areas are mainly volcanic or alluvial. The direction of the 

 fall of some of the leads 'v? sho^vTl by arrows. 



Fig. 6. Diagrammatic cross section of the Grampians, south of 

 Hall's Gap. The full lines show the probable position of the 

 fault lines along two valleys, the dotted lines probable other 

 faults whose number and position are uncei'tain. The depth lo 

 which the sandstone extends is also uncertain. 



Fig. 7. Profile of the Pyrenees as seen from Maiden Hill near 

 Waubra. Mt. Mitchell, in the foreground, is a volcanic hill. 

 The increasing distances of the hills are shown by fainter lines.
