about a mile apart, tlie beach being strewn with stones from 

 the size of a pebble up to large boulders. The presence of 

 granite was noted among these shore pebbles, having been prob- 

 ably transported from a distance by some natural agency, as 

 granite does not occur in sltio in the neighbourhood. The 

 larger boulders were seen to be massive conglomerates contain- 

 ing pebbles of gneiss and quartzites. Professor Tate explained 

 that this conglomerate was to be seen in situ some distance 

 northward, and that it formed part of a series that occupied a 

 much lower position in the sedimentary rocks of the colony. 

 The southern headland, appropriately called Black Point, is 

 formed of dark shales of a purple color standing nearly on edge. 

 By approaching this point from the rear, the crest was reached, 

 .and, by looking down, it was seen that the stratification is inter- 

 rupted by curves and intricate foldings. 



Proceeding along the top by a narrow terrace, hemmed in 

 above by the second cliff of horizontally stratified grey sand- 

 stone, the party arrived at a place scarcely a quarter of a mile 

 distant from Black Point, where the surface of the underlying 

 slate was laid bare, quite smooth, and scratched and grooved 

 in a generally north and south direction. These polished and 

 scratched features Prof. Tate explained as due to the action of 

 ice at some former period, whereupon a lively discussion took 

 place, those members well versed in recognising the toolmarks 

 made by ice acquiescing with the opinion of the Professor. 

 On returning, the party proceeded to examine the second line 

 • of cliffs, composed of red and grey Tertiary sandstone, and 

 found that the sandstone, at about half the height of the cliffs, 

 -contained a number of fossil shells. Prof. Tate said that he had 

 found between 50 and 60 species of fossils in this formation, 

 which could be seen to better advantage at Aldinga, where cor- 

 responding beds rest on older fossiliferous rocks. This upper 

 series he referred to the Miocene period, and the lower, at 

 Aldinga, to the Eocene. It was the nearest place to Adelaide 

 where the formation could be studied. The surface was of an 

 arid character, but in spring yielded many interesting plants. 

 Of these the following were more particularly observed, viz. : — 

 Goodenia amplexans, Gr. albiflora, ^lyoporuin parvifolium, 

 Pittosporum phyllii\Toides, Ptilotus nobilis, Sida corrugata, 

 Boerha'via diffusa. 



On re-assembling at the encampment by the stream a 

 meeting was held. Prof. Tate presiding, wlien several 

 members were elected. After tea had been ])artaken of 

 and an early return party taken their leave, tlie remain- 

 ing members were conducted up the gorge, wliere Pro- 

 fessor Tate pointed out the rocky walls of massive lime- 

 stones, here and there crumpled and bent in a most intricate
