REMARKS ox EXHIBITS. 



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

 number of small jilant seedlings and herbarium specimens of 

 an luidescribcd s})ecies of eucalyi>t which he discovered in the 

 Belgrave district in March, iqi(). The species resembled E. 

 viminulis in some respects. He asked members who might 

 visit Belgrave during the spring and summer montl\s to keej) 

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

 undescribed variety was limited. 



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

 specimen of the Sunshine Wattle, Acacia discolor, W'illd., which 

 usually flowers in April and May. but is now flowering freely in 

 the Botanic (hardens. 



P.\PER READ. 



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

 to the Jenolan Caves." 



In briefly outlining the physiography and geology of the 

 locality 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 by the mounted i)olice who were in pursuit of 

 him. Since then they have been visited by thousands of 

 |)eople, and the locality has become one of the most im])ortant 

 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 }n"esent jiosition towards 

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

 demonstrate that the ])ene-plain has been cut out of a still 

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

 a residual. Following on the uj^lift a cycle of erosion ensuf^d,

 Cave Limestone those subterranean jmssages through which 

 the tourist now wanders in amazement. The })aper was illus-
