A hard fine grained argillaceous sandstone varying in 

 colour from a very light to a darker green is the predomina- 

 ting rock-material, and this kind usually exhibits the most 

 marked striations. Another common variety is a hlue-black 

 very hard quartzite. These, though commonly exhibiting 

 flattened or facetted sides and angles, seldom show stria', 

 their surfaces being more often polished. 



Granite often occurs though not so frequentl}' as the other 

 kinds of rock. The largest boulders are of this material. 

 One taken from the cutting can be seen 13'ing at the side of 

 the road, which is well flattened on one side. The granite 

 is generally considerably decomposed. At the top of the 

 cutting a large angular fragment of sandstone occurs, while 

 another piece can be seen at the base ; whether the latter is 

 in situ or not we have not yet determined. 



The unstratifled nature of this deposit, together with the 

 peculiar nature and want of arrangement of the included 

 stones, at once stamps it as of glacial origin. 



A few feet back from the top of the cutting on the south 

 side, an outcrop of white silicious sandstone occurs. We 

 are inclined to think that the glacial deposit is banked uj) 

 against this, really overlying it. 



A short distance below the cutting a small lateral road 

 joins the main one, and on this road, a hundred yards or so 

 from the junction, another cutting exposes a good section. 

 The material exposed is similar to that just described, but 

 is of a more uniform purple colour. It is also somewhat 

 harder. It is quite unstratifled and contains numerous well 

 striated stones. On the surface, on both sides of this cutting, 

 glaciated stones aj-e scattered about in great profusion and 

 variety. This deposit apparently overlies sandstones and is 

 continuous with that exposed on the main road. 



Before making our next visit to the locality, we wrote to 

 Mr. Chai'les Brittlebank, of Dunbar farm, near Myrniong, 

 who, we were led to believe, could give us information in 

 our researches. Mr. Brittlebank readil}' responded, and 

 during our subsequent visits has rendered us much valuable 

 aid. He has accompanied us on most of our expeditions and 

 shown us much hospitality, while his intimate knowledge 

 of the locality, as well as his keen powers of observation, 

 have been of the greatest assistance to us. Mr. Brittlebank 

 informs us that he found glaciated stones in this district 

 four years ago. He thus appears to have been the first to 

 actually prove the glacial origin of the deposits in question.
