of the ridge, just referred to, the glacial beds skirt the 

 orchards of Heywood, the residence of Mr. Hancock, sen., 

 near the summit of Wood Cone, close to Mount Jagged, where 

 they reach an elevation of more than 300 ft. above the valley, 

 and are within 100 ft. of the height of Mount Jagged. A 

 small quarry has been opened in these beds near Mr. Hancock's 

 house (for mending the road), from which I obtained a very 

 fine faceted and striated boulder of black quartz, 8 in. in 

 length. There can be no doubt that Wood Cone was at one 

 time buried under glacial waste in common with the sur- 

 rounding district. It owes its present freedom from such ice- 

 borne material on account of the steepness of its sides and 

 the force of running water which has deeply scored its flanks. 

 Mount Jagged is also free from morainic deposits, but these 

 are met with on the southern slopes of the range, covering a 

 large area and passing westerly into the Hundred of En- 

 counter Bay. 



On the eastern side of the basin are two conspicuous 

 ridges entirely composed of glacial sandstones (or their 

 waste), and surrounded by swamps, as already described. 

 Cleland's Gully divides the two ridges and forms the main 

 artery of drainage for the district. The ridge on the southern 

 side of Cleland's Gully is about 150 ft. in height, and forms 

 the dividing line between the Hundreds of Nangkita and 

 Goolwa. 



The presence of pebbles is a characteristic feature of the 

 district. They occur in situ in the clay of the lower members 

 of the series as well as in the sandstones of the upper mem- 

 bers and in the loose sand that has resulted from the disin- 

 tegration of the beds. They occur, moreover, at all eleva- 

 tions, even on the summit of Mount Compass and other 

 heights, in positions where the finer, sandy material has been 

 entirely removed by denudation. They are mostly varieties 

 of quartz (a black variety being not uncommon), close-grained 

 quartzites, and a few granites. Clearly-defined examples of 

 the local Pre-Cambrian rocks, among these pebbles, are rare. 

 The stones are intensely waterworn, some being almost spheri- 

 cal or oblate spheroids in shape. None of these stones per- 

 taining to the glacial beds of the Mount Compass basin were 

 observed more than 18 in. or 2 ft. in diameter, and stones of 

 this size were not often met with. Pebbles were found to be 

 specially abundant on the south side of Mount Efiie. Here 

 they had evidently been concentrated by wind action ; the 

 finer material had been carried away by the wind and the 

 stones left behind. 



Mr. Hancock informed me that the pebbles were usually 

 more abundant on the western than on the eastern slopes of
