made travelling very enjoyable. Owing to the long-continued 

 dry weather there were very few plants in bloom. Mr. W. H. 

 Selway, who was leader for the day, addressed the party, and 

 recalled earlier visits to the locality, notably one in Professor 

 Tate's time. He pointed out that in this sandy area, similar 

 in some respects to the miocene uplands near Highbury, the 

 plants completed their cycle in a comparatively short period, 

 and were of special botanical interest in that respect. An 

 abundance of parakeets was observed, and two kinds of lizards 

 were seen. The botanical results were very encouraging, and 

 the party travelled further on, with the object of seeing a part 

 of the Little Para River possessing features of geological 

 interest, Vv'hich had been explained on a former occasion by 

 Professor Tate. The return journey was by way of Teatree 

 Gully. 



Lecture, May 17, 1921. — Mr. Henry Savage lectured to a good 

 audience on ''Papuan Scenery." The lecturer described a trip 

 taken by himself and others recently along the south coast of 

 the island, with an excursion inland. This great island has 

 notably high mountains (one peak being 13,250 feet high), 

 abundant rainfall, and large rivers; the Fly River is 40 miles 

 wide at its mouth. The natives and their customs and legends 

 were dealt Avith in an interesting way, and many excellent 

 illustrative photographs were shown, also samples of native 

 workmanship of articles made for peace, war, and worship. 

 The plants and the general fine scenery were also well depicted 

 and described by the lecturer. 



Excursion, May 21, 1921. — Under the guidance of Dr. 

 Fenner, a party explored the cliffs and quarries of Waterfall 

 Gull3v\ The history of the uplift of the great Cambrian and 

 pre-Cambrian block of the Mount Lofty Ranges was dealt 

 with from the point of view of the evidence found during the 

 excursion. The subsequent carving out of the valleys of Sturt 

 River, Brownhill Creek, and the First, Second, Third, Fourth, 

 etc.. Creeks was dealt with, and the remarkable way in which 

 Sixth Creek has extended its territory southward, behind the 

 head waters of the other streams, was pointed out. Of the 

 streams flowing both to the east and west from this range, few 

 reach the sea ; they deposit so much sediment that their waters 

 are usually lost in these porous accumulations. Interesting 

 facts of plant and animal life were also noted during the trip, 

 particularly the remarkable numbers of Wanderer butterflies 

 that hung, like swarms of bees, on the shad}^ side of some of 

 the eucalypts. At the fall some of the party were taken in 

 hand by the enthusiastic curator, Mr. Hogan, and conducted 

 to various points of vantage, from which charming views of 

 cliff and fall and distant sea were obtained.
