variably determined by the existence of this forest tree, espe- 

 cially in the broad belt of timber that crowned the main road 

 approaching Golden Gi-rove. The graceful poison-berry tree, 

 Fittosporum phillryceoides, is here exclusively confined to the same 

 habitat in this locality. Bulinus texturatus was collected in the 

 river. The habitat of the Quinetia Urvillei, a very rare annual of 

 West Australian origin, discovered here some years ago by Pro- 

 fessor Tate, was visited. Here Ptilotus eriibescens was found ; 

 and then the scrub at Grolden G-rove was explored, but the 

 many floral productions for which it is famous had now 

 almost passed away. A few, however, remained, among which 

 were Daviesia ulicina, var. ruscifolia, and the grass Ampliipogon 

 stricius. The Professor explained that the surface drainage 

 from the scrub had in the course of a few years cut for itself a 

 channel some yards in width, and of a depth of twenty feet 

 ill the sands and clays which overlie the sandstones and stiff 

 argillaceous beds of the "Upland Miocene." The same beds 

 were also visible in the roadside cuttings, where the horizontal 

 arrangement of these sandstones are unconformable to the 

 grits of the old rocks. The peculiar vegetation of these 

 scrublands was at this place clearly seen to be referable to this 

 geological phenomenon.

About thirty members and friends of the Section proceeded 

 to Uraidla via Norton's Summit. On arrival at Uraidla the 

 party were met by Mr. G-rasby, of Oakbank, and Mr. "Wilson, 

 of Uraidla, who courteously volunteered their services as 

 guides. 



After walking for about a mile a meeting was held — Mr. W. 

 H. Selway, jun., presiding — and two new members elected, and 

 a hearty vote of thanks passed to Mr. Wilson. The party 

 then descended to the foot of a waterfall at the head of a 

 beautiful glen. 



After lunch the walk was commenced, and on the way 

 attention was directed to the undulated foliation of the slates 

 and quartzitic grits wherever exposed in the rocky walls bor- 

 dering the deep gullies along which the road lay, and which 

 was produced by lateral pressure. The talcose slates generally 

 occupy the lower portions of the hillsides, while the quart- 

 zites dominate the ridges, which are usually occupied by 

 the stringybark forests. It was pointed out that the configur- 

 ation of the country, inclusive of almost equi- distant secondary 

 lateral gullies, was due to erosion by the agency of rain upon 

 strata of different densities. The formation was the same as 

 that formerly observed at Crafers and the neighbourhood o£
