neighborhood, or were carried there. I am unable to say. 

 To all appearance the only deposit superior to the glacial 

 -clay in the neighborhood is a thin crust of travertine lime- 

 stone which lies directly on the boulder clay. 



(b) Corney Point Road. — A large erratic occurs near the 

 main road from Warooka to Corney Point. It is situated on 

 the north side within about twenty yards of the road in 

 Section Xo. 148. Hundred of Carribie, about two miles east 

 of the Dairy Station, and seven miles from Corney Point. 

 Its large size and isolated character has attracted general 

 attention in the district, and has been recorded on the Go- 

 vernment Map as the "Granite Rock." It measures above 

 ground 7 ft. x 5 ft., but to all appearance its actual size 

 is much greater. It is not a "granite rock" but a greyish- 

 colored, granular, hornblendic schist, having a close re- 

 semblance to some of the highly metamorphic rocks on the 

 coast at Corney Point. From the effects of weathering it 



has split into several pieces — the measurements given are in- 

 tended to include the block as a whole. The occurrence of 

 this transported stone in the position described, is interest- 

 ing, as it marks the most westerly point that I was able to 

 note the presence of glacial deposits. 



(c) Lake Fowler. — This is the largest of the numerous salt 

 lagoons that are scattered over the southern portions of 

 Yorke's Peninsula. It is situated about four miles south of 

 Yorketown. and is more than ten miles in circumference. 

 The Lake occupies a depression in the boulder clay, proof of 

 which can be seen at various points both on the lake bottom 

 as well as in the cliffs that surround its margin. The most 

 interesting assemblage of glacial features met with in my 

 visit was on the north side of the Lake, in Section Xo. 178 

 (Hundred of Melville) at a spot that can be reached by a 

 path from the road, through a slip panel, and across a field. 

 Xear where the path strikes the lake the sloping bank con- 

 tains a group of twelve large pieces of pink-colored granite, 

 having but a slight elevation above the ordinary level. The 

 group measures ten feet by six feet, and was "probably only 

 one piece orginally. but has split along joi] tlanes as the 

 result of weathering. 



About eighty yards to the westward of this erratic, other 

 two huge granite blocks can be seen standing in the mud of 

 the lake about a dozen yards away from the base of the 

 cliff. On examination it was evident tnat the two fragments 

 had been originally one block, the vertical fissure having pro- 

 bablv occurred after it had become stranded in its present 

 position. Conjointly they measure six feet six inches high 

 and eight feet wide. Lying around this great erratic are
