EXCURSION TO YERING GORGE. 



Quite a large party of members and friends, numbering thirty, 

 detrained at Yering on Cup Day, Tuesday, 3rd November, for 

 the purpose of visiting Yering Gorge. The morning was bright 

 and warm, but a pleasant breeze from the south, though some- 

 what faint at times, tempered the heat of the sun. Yering 

 station is situated in the midst of alluvial flats, well cultivated 

 for the purpose of supplying milk to the metropolis. Our 

 objective was about two miles away due west. Rambling 

 thither we passed two or three good specimens of the soft-leaved 

 wattle. Acacia moUissima, in full bloom, and noticeable at a 

 distance by the strong perfume diffused. As we approached the 

 river, signs of the dry season were evident, from the fact that 

 some small swamps, seldom seen without some water in them, 

 were quite dry. Reaching a bend of the river, a halt was called 

 for a few minutes, when a number of fine specimens of the 

 orchid Pterostylis cuciillata were found among tufts of grass and 

 moisture-loving plants, such as Mazus pumilio, Cardamine 

 laciniata, Claytonia australasica, Rammculus rividaris, Isotoma 

 fiuviatilis, &c. Following down stream a fine grove of Kunzea 

 pedtmcidaris just bursting into bloom was met with. Here we 

 decided to lunch, and tea was soon made. The ieni Poly podium 

 punctatum grew luxuriantly close by ; presently a solitary 

 specimen of Solanum aviculare, with its handsome purple flowers, 

 was met with ; then a thicket of hazel scrub, Pomaderris apetala, 

 P. racemosa, and Spyridium parvifolium, was entered, in which 

 were found a couple of specimens of the Potato Orchid, Gastrodia 

 sesamoides, in flower. Here also was a fine patch of the hepatic 

 Marchantia polymorpha, and close by some sphagnum moss. 

 Emerging on a dry hillside, where a young copper-head snake 

 was killed, we were now in the Gorge proper, for some 

 notes on the physiography, of which I am indebted to Mr. 

 F. Chapman, A.L.S., who was one of the party. He says: — 

 "The country around the area traversed in our excursion 

 is of very great interest to those who study physiography. It 

 is, moreover, one of the most complex of the districts cut 

 through by the Yarra in its course from the Baw Baws to the 

 sea. Our track lay along the Yarra flats, west of Yering 

 station. The underlying rocks of this area are soft mudstone, 

 similar in character to that found just north of Lilydale, and 

 which is so abundantly fossiliferous. It is also of similar age,
