double line of |)i])i]iir. A well holds about 1,000 gallons, and 

 wheii pumped dry will fill ajraiu in twenty-four hours. The 

 lecturer spoke at length of the natives seen, and their customs. 

 Two kinds of wurlie were ))uilt, one for Avet weather, made of 

 branches of trees, and one for summer of a more primitive 

 character. In Avinter two fires were made, between which the 

 natives slept minus clothes, Avhich would probably get burnt 

 otherwise. This refers, of course, to the natives living near 

 the line and in contact with white people, who had supplied 

 the wardrobe. Some natives of fine physique were seen at 

 Ooldea, and out of a large number examined by the doctor only 

 two decayed teeth were seen. The men Avere adepts at the use 

 of the spear, and could, apparently Avithout taking aim, hit 

 their object Avith ease. Dr. Pulleine explained some of the 

 native dances and the method of adorning themselves Avhen so 

 engaged. Their ornaments, such as nose bones or sticks, shells, 

 and the chignon for the hair, Avere portrayed. Numbers of 

 vieAvs of native animals Avere shoAvn, among them being the 

 moloch, or mountain devil, cave oavIs, marsupial mice, bilby, or 

 hair-ear bandicoot, rat AA-ith bushy tail, and others. 



Excursion to Port Noarlunga, June 26, 1922.— A party 

 visited Pt. Xoarlunga under the leadership of Mr. \V. J. Kimber. 

 The first inspection Avsa made at the fossil cliffs on the north 

 of the jetty, and in the afternoon the party Avent along the 

 south side of the river. Several interesting finds Avere made 

 in the fossil-bearing rocks in this locality, the leader chipping 

 out a fine fossil echinoderm, the other excursionists securing 

 several lamp shells, Avhich Avere plentiful in tertiary times, 

 but have left very fcAv descendants in the Avaters of modern 

 seas. The party were able, Avith the guidance of the leader, 

 to identify many of the numerous shells, Avhich are found as 

 fossils in the rocks bordering the mouth of the River Onka- 

 paringa. The geologically recent raised plain, through Avhich 

 the LoAver Oonkapariuga meanders, proved of great interest to 

 the visitors. 



Lecture, "Shell Study Simplified," June 20, 1922.— The 

 first of a series of lectures, arranged by the Committee, to deal 

 with various branches of natural history in an elementary way 

 was given by Mr. W. J. Kimber on June 20. He said that 

 Molluscs Avere soft-bodied animals, usually protected by a 

 univalve, bivalve, or multivalve (chiton) shell, and Avere the 

 most highly organised of the Invertebrates. They are divded 

 into four classes, viz.: Cephalopoda (Nautilus, Octopus, etc.), 

 Gasteropoda (Snails, Winkles, etc.), Pelecypoda (Oysters,
