octophylla was in blossom, but P. phylicoides had passed into 

 fruit. Stackhousia linarifolia, Tricoryne elatior, Ccesia vittata, 

 Comesperma ericinum, Eryihrea spicata were all over the downs, 

 while Gom,pholobium huegelii, Patersonia glauca, and Prostanthera 

 denticulata could be seen in shady places. The view along the 

 coast range coming back was really beautiful. On one side glimpses 

 of the ocean could be seen stretching between Barwon Heads 

 past the Airy's Inlet (Split Point) lighthouse to just beyond Lome. 

 To the North was the whole basin of Swampy Creek, with the 

 hills forming part of the Otway Forest as a background. 



My curiosity was aroused by the account of a singular plant 

 which was said to grow on some of the rocky portions of Point 

 Roadknight, up which very few had attempted to scramble, so I 

 took a special trip to find it, and after some time succeeded. I 

 had not seen it before, and was rather uplifted, but my friend 

 Mr. C. Walter assures me it is fairly common near Brighton, the 

 plant being Alyxia buxifolia. While there I secured some plants 

 of Calocephalus brownii, which forms great cushion-like masses 

 all over the Point. This turns out to be rather uncommon, as it 

 is often overlooked, being very much like other species of 

 Calocephalus in habit. 



In conclusion, I might remark that Anglesea River seems to 

 me an exceptionally good place for a field naturalist. It is only 

 a seven hours' journey from Melbourne, and as the steamer and 

 coach fare is only twelve shillings and sixpence for the return 

 journey of 140 miles the expense is not heavy. 



A BEHEADED VALLEY. 



By T. S. Hall. 

 (Bead before the Field Naturalists' Club of Victoria, 10th April, 1900.) 

 Valleys may be divided, from the point of view of their origin, 

 into two groups, those which have not been formed by the agency 

 of running water and those which have. The first group includes 

 such valleys as are formed between the advancing ridges of sand 

 dunes. These may be of considerable length, and readers of 

 Carnegie's " Spinifex and Sand " will remember his struggles in 

 their labyrinths in Central Australia. Again, valleys may be 

 formed between volcanic cones or between sheets of lava. Other 

 members of the same great group may owe their origin to earth- 

 folding or to faulting. Thus parallel faults, extending for great 

 distances, may have let down the intervening country, and so 

 have produced a great valley. However, the most usual method 

 of valley formation is by the action of running water. Given 

 time and a stream will cut through anything. In streams with a 

 rapid fall the greatest amount of cutting is done in the channel
