10 THE VICTORIAN NATURALIST. tVol. XXV. 



of Mr. G. K. Donaldson, on whose property the quarries are 

 situated. We were sorry to find Mr. Donaldson suffering from 

 the result of a severe riding accident. Mr. E. E. Johnson, a 

 former member of the Club, joined us here. As it was now 

 lunch time, a fire was lighted and tea made. We then visited the 

 quarries, and spent about three hours in examining them and their 

 surroundings. The members were greatly interested in the 

 abundant evidences of the aboriginals' handiwork as displayed 

 in the numerous chipping places, both on the hillsides and in the 

 valleys, and it was hard to realize, from the appearance of the 

 heaps, that more than fifty years had elapsed since the last axes had 

 been shaped there. Several unfinished tomahawks were obtained 

 as mementos of the visit. An attempt was made to photograph 

 some of the stone heaps, but, owing to the unfavourable weather 

 conditions, the results were not very satisfactory. The main party 

 then returned to Lancefield and thence to town, while Mr. 

 Armitage and myself, after photographing some tors, made our 

 way to Mr. Johnson's house, Mr. Johnson having kindly offered 

 to put us up for the night. 



Before breakfast on the Sunday morning I went to an adjacent 

 slate quarry in the vain hope of finding graptolites._ After break- 

 fast we walked down the valley to the south, and in a couple of 

 miles came to the well-known Lancefield graptolite quarry. Here 

 we found a fairly large party, including Mr. Barnard, who had 

 stayed the night in Lancefield. We spent a long time in the 

 quarry, and everyone secured a few graptolites, though till 

 further opening up takes place not much good collecting can be 

 done. A return was then made to Mr. Johnson's for lunch, and 

 then three of us — Messrs. Barnard, Brisbane, and myself — climbed 

 the I, GOO feet to the top of Mt. William. The cairn marking the 

 trigonometrical station is now so surrounded by trees that nothing 

 can be seen from there. A little to the southward, however, 

 from clear ground, a very extensive view is to be obtained. 

 Mt. Alexander shows through a gap to the north-west, and Mt. 

 Disappointment is seen in the opposite direction, and a series of 

 flat-topped ranges stretches from Mt. Disappointment far to the 

 northward. Unfortunately haze and smoke prevented us from 

 picking out many landmarks, but Kilmore and Lancefield town- 

 ships were easily seen. 



A few notes may be added on the geology of this interesting 

 district. The oldest rocks exposed are the Lancefield shales, 

 the lowest Ordovician that we know in Victoria. They are 

 usually dark blue in colour, and in places are much indurated, 

 sometimes being almost cherty. Near the disused Mt. William 

 railway station very silicified beds are displayed in the cuttings. 

 Near Mr. Johnson's house a road leaves the Pyalong road and 

 runs east across the Mt. William range. On this road the blue
