KF.roRDERS. 



Mr. H. Witty asked it the eommittee liad taken any action 

 to appoint recorders for the various branches of natural history, 

 as suggested by him some time ago. If nothing had been done 

 in the"matter/he would give notice of his intention of moving 

 — "That recorders be appointed"; and would communicate 

 with the hon. secretary later on the subject. 



REMARKS ox EXHIBITS. 



Mr. P. R. H. St. John called attention to his exhibit of a 

 number of small plant seedlings and herbarium specimens of 

 an undescribed species of eucalypt which he discovered in the 

 Belgrave district in March, 1916. The species resembled E. 

 viminalis in some respects. He asked members who might 

 visit Belgrave during the spring and summer months to keep 

 a look-out for the species. So far the number of trees of this 

 undescribed variety w^as limited. 



Mr. F. Pitcher drew attention to his exhibit of a flowering 

 specimen of the Sunshine Wattle, Acacia discolor, Willd., which 

 usually flowers in April and May, but is now flow^ering freely in 

 the Botanic Gardens. 



PAPER READ. 



By Mr. J. H. Harvey, A.R.TV.A., entitled " A Holiday Trip 

 to the Jenolan C'aves." 



In briefly outlining the physiography and geology of the 

 locaUty in which the caves are situated, the author mentioned 

 that these wonderful underground caverns were discovered in 

 1841 by a bushranger named M'Ewan, and were made known 

 to the public Jw the mounted police who were in pursuit of 

 him. Since then they have been visited by thousands of 

 people, and the locality has become one of the most important 

 tourist resorts in New South Wales. The caves are situated 

 on the Jenolan River, about 36 miles from the Mount Victoria 

 railway station, in what is called the Blue Mountain Tableland. 

 This pene-plain, which is now much dissected by stream- 

 erosion, has an altitude of from 3,000 to 4,000 feet, and is 

 believed to have been elevated to its present position towards 

 the close of the Tertiary period. Evidence is not lacking to 

 demonstrate that the pene-plain has been cut out of a still 

 older tableland. Mount Binda (4,460 feet) being instanced as 

 a residual. Following on the uplift a cycle of erosion ensued, 

 and the Jenolan River and its tributary, M'Ewan's Greek, in 

 the course of vast periods of time carved out in the Silurian 

 Cave Limestone those subterranean passages through which 

 the tourist now wanders in amazement. The paper was illus- 

 trated bv about 130 lantern slides of exceptional merit, most
