THE VICTORIAN NATURALIST. 15 



served in the reddish shales. The exposure was a small one, in a 

 dry gully a few chains to the south-east of Reid's hut. This 

 interesting find bears out the view that has been put forward that 

 the red sandstones and shales of the whole of the area form part 

 of the Avon series, which were regarded by M'Coy as Upper 

 Devonian or Lower Carboniferous. 



When Reid arrived a start was at once made for the country 

 beyond Glencairn. At a spot on the Macallister River, just 

 above where the northern outlet of the Glencairn valley 

 empties itself into the river, the main stream divides into two 

 branches of approximately equal size and volume. The easterly 

 branch ,had perhaps a slightly stronger stream at the time 

 of our observations. One branch continues more or less 

 northerly, while the other makes a big sweep to the east at 

 right angles to the course of the valley below the junction. 

 Which branch is the Macallister ? This question puzzled us. 

 Murray accepts the east branch on his map, but does not even 

 name the northern branch, which is only indicated as a subor- 

 dinate tributary in the northern edge of his map. On the geolo- 

 gical map of Victoria the Macallister River is shown continuing 

 right up to the Main Divide to the west of Mt. Clear, but an 

 intervening river between the Macallister and the Wellington is 

 shown, which does not exist at all. The northerly branch 

 appears to have always been known locally as the Macallister, 

 and the easterly branch as the Caledonia. This view has been 

 accepted in the rough sketch map appended. 



The northern branch was followed up about three miles. This 

 valley was so scrubby that travelling was by no means easy, 

 especially for the pack-horse. The steep mountains so shut in 

 the river on either side that very little could be seen. A camp 

 was therefore established at a spot on the east side of the river 

 where the slope to the mountain was a little more gradual and 

 there was some picking for the horses. Two of the party then 

 climbed a steep, rocky spur to a prominent point 2,500 feet above 

 the camp to reconnoitre for a spur by which to climb with the 

 horses to the snow plateau. A magnificent view was obtained. 

 Away to the north stretched the valley of the Macallister right 

 up to the Divide. Immediately to the south lay the deep, pre- 

 cipitous valley of the Caledonia, trending eastwards towards a high 

 hne of the snow plains. On the southern side of this valley a 

 huge wall of mountain face rose up to form the northern termina- 

 tion of the " Crinoline " ridge, which here turns sharply east to 

 rise to Tamboritha's summit. 



The same interesting rock structure referred to earlier in this 

 paper was again clearly marked. The main mountain mass 

 right up to the top showed clearly the horizontal rock ledges, 

 while the western spurs of the Macallister valley were strikingly
