deposits, though he is apparently inclined to regard the glacials and 

 the Jurassic sandstones as quite conformable with each other. He 

 records these glacial deposits as extending altogether for about one 

 and a quarter miles, but not in a continuous mass — the two deposits 

 being about one mile apart. 



I recently examined the locality about the road cutting at Chitt 

 Creek, and have no hesitation in giving my opinion that the material 

 is of glacial origin. Pebbles up to the size of a man's head, and show- 

 ing polish, grooving, and striation are not uncommon ; while smaller 

 pebbles, similarly marked, are present in considerable numbers in a 

 gravelly clay. On the hillside, however, I was not able to see the out- 

 crops of Silurian rocks nor the glacial deposits, for a recent landslip 

 from the overlying Jurassics had covered the hillside with soil and 

 Jurassic rocks. 



The material in the road cutting is, in my opinion, not in situ, but 

 part of an old landslip from probably 50ft. higher up the slope. The 

 Silurian strata occurring here form the eastern extension of the Foster 

 goldfield belt of Silurian (?) rocks, and the Jurassics occur at about 

 100ft. up the slope, and comprise the mass of the country extending 

 northward for a great many miles. 



From such evidence as I saw, and long acquaintance with the 

 Jurassic rocks of South Gippsland, I am rather inclined to the belief 

 — though I do not definitely advance it — that these glacial deposits are 

 more of the nature of large lenticular masses in Jurassic sandstones 

 than consisting of one continuous bed. During my survey of the South 

 Gippsland coalfields and adjacent country I frequently found, occurring 

 as small lenticular beds of conglomerate or scattered pebbles, among 

 Jurassic sandstones, rocks such as usually occur in glacial deposits and 

 others as well, and in a paper, " Volcanic Rocks at Anderson's Inlet, 

 South Gippsland," published in Proceedings of Royal Society, Victoria, 

 in 1903, have cursorily described them, suggesting a direct or indirect 

 glacial origin for them. 



Mr. Ferguson, in his paper above referred to, states he also came 

 to the conclusion prior to the discovery of the glacials at Chitt Creek 

 that blocks of sandstone, granite, &c., among the Jurassic sandstones 

 were due to shore ice.
