crossed this barrier in its passage westward, leaving abundant 

 evidences of its former existence by thick deposits of drift and 

 glaciated stones on the summit of the range, with drift beds, 

 numerous erratics, and the polished rock surfaces already referred 

 to on the western or further flanks of the watershed. At the 

 summit of the Bald Hills the soil is deep and remarkably dark in 

 colour, more like a marsh soil than what usually occurs on the 

 crest of a hill. This "rich black soil of the Bald Hills" attracted 

 Selwyn's attention, but he was unable to account for it. It is 

 not unlikely to have been derived from a similar deposit as the 

 bluish black glacial drift, which has a considerable development 

 in the Inman Valley. 



Time prevented a close examination of the lower levels of the 

 Bungala Valley, which near Yankalilla are largely obscured by 

 recent river wash, but glaciated erratics were observed on the 

 hills two miles north of Norman ville at a height of about 200 ft. 

 above sea level. 



Taking advantage of the Easter holidays, one of us returned to 

 the district for further investigations. The Bald Hills watershed 

 was explored to the northward of the main road, when granitic 

 and other erratics were found scattered over Mr. J. R. Kelly's 

 fields near the crest of the hills, some of them being facetted and 

 scratched. 



A high ridge runs up the centre of the main east and west 

 valley between Port Victor and Normanville, separating the 

 Inman Valley from the Back Valley. At a point about seven 

 and a half miles from Yankalilla a district road was followed, 

 which passes over this central ridge. Erratics were seen at inter- 

 vals on the rise, some of considerable size; and a granite boulder 

 three feet in diameter was noted close to the road near the crest of 

 the hill. As near as could be judged, in the absence of an aneroid, 

 this ridge is about 500 ft. above the bed of the Inman, and about 

 100 ft. above the greatest height of road that passes over the 

 Bald Hills. After passing the crest of the hill, the ground drops 

 about 100ft., and the road continues along the crest of a lower 

 range, which has a trend of S.S.E. and N.N.W. On this range 

 there are two road cuttings, each about 100 yards in extent, 

 showing soft yellow sandstones, unstratified, but contorted. 

 Dark-coloured argillaceous bands run most irregularly through 

 the stone, sometimes forming loops. No stones were seen in the 

 sandstone itself, but several striated stones were picked up loose 

 in the cutting. About a quarter of a mile beyond the second 

 cutting a stony patch is exposed on the northern side of the road 

 on the slope of the hill, many of ths stones showing glacial 

 features. The bed of the Back Valley Creek is much silted, and 

 only two small patches of the yellow sandstone similar to the
