136 Excursion to Ringwood. [vd!"'xxx

that all has not yet been worked out in regard to their past and 

 present phases. The varying and associated levels of ridges, 

 hills, and mountains point to peneplains or denudation levels 

 of moderate to vast antiquity. " Pinemont " stands out, as 

 do other hills in the vicinity, as a monument to the indefatigable 

 work of patriarchal rivers. It is called a monadnock, in keeping 

 with other like hills formed by surrounding denudation, the 

 typical one being Monadnock Hill, in New Hampshire. To 

 the north he the Plenty Ranges, with Kangaroo Ground and 

 its lava-sealed river-bed in the middle distance. Just below, 

 to the east, is the great strath of the Croydon sunkland, with 

 its prolific orchards, and farther afield the forest-clad volcanic 

 stump, the Dandenong Ranges. Sweeping along the eye-line 

 to the south-east the level of the lower peneplane is strikingly 

 seen, whilst to the west are the lava-covered plains under which 

 he buried the old river valleys of the Plenty and adjacent river 

 systems. Descending " Pinemont " on the south-western side, 

 a cart track led us to the old quarry. A cursory examination 

 with eye and hammer showed only a few impressions and stains, 

 probably due to the worm Trachyderma. It was from this 

 quarry that fragments of a brachiopod were obtained some 

 years ago by Dr. Thiele. As the matter of determining the 

 horizon in this district is of some importance to geologists, it 

 is hoped that future geological collectors will concentrate their 

 attention upon it. The walk to Mitcham station took us along 

 the banks of the Deep or Mullum Mullum Creek for a short 

 distance. The torrential nature of the stream-bed here was 

 noticed, which shows it still possesses considerable erosive force, 

 and to be actually in the phase of rejuvenation, as evidenced 

 by its steep banks. The many interesting problems for 

 geologists arising out of this short ramble amply repaid any 

 special efforts of the members to attend the excursion. — F.

Seeds of Native Shrubs and Plants. — With the view of 

 encouraging the growth of those members of our indigenous 

 flora suitable for garden plants, it is hoped to have on sale 

 at the next exhibition of wild-flowers packets of seeds of various 

 kinds. Country members especially can help materially in 

 this direction by collecting, during the summer, seeds suitable 

 for the purpose. Care must be taken that these are true to 

 name. The following gentlemen will be glad to give advice 

 and receive collections : — Dr. C. S. Sutton, Rathdown-street, 

 North Carlton ; Mr. P. R. H. St. John, Botanic Gardens, South 

 Yarra ; Mr. C. Daley, B.A., Clarinda-street, Caulfield ; or Mr. 

 H. B. Williamson, Princes-avenue, Caulfield East.
