592 president's address. 



In the Carboniferous rocks at Agate Hill Mr. Hardman describes* 

 a bed of white chalcedony 100 to 150 feet thick. 



Amongst the fossils recorded may be mentioned! Producta 

 gigantea, P. semireticulata, Streptorhynchus crenintria, RhyncJionella 

 'pleuvodon^ Sinrifera lata, Poteriocrinus, Stenopora Tasmaniensis, 

 ZaphrentiSj Stromatopora. The sandstones of the Upper Series 

 pass downwards into conglomerates. They contain much nodular 

 haematite. At Yarralla Hill Mr. Hardman records | the occurrence 

 of Lepiidodendron, Lepidostrobus, Lepidophyllum, Sigillaria and 

 Sagenaria ; and Mr. H. P. Woodward also mentions the occur- 

 rence of Cyjyei'ites.^ 



I am informed by Mr. R. Etheridge, junr., that the specimens 

 of Lepidodendron collected by Mr. Hardman were presented to the 

 Imperial Institute. It is much to be hoped that they will shortly 

 be described and compared with East Australian forms. A brief 

 description has already been published by Mr. A. H. Foord,|| from 

 which it would appear that the specimens are unlike L. austrahf 

 but they were mostly very imperfectly preserved. 



Folding. — In Victoria the general direction of folding of the 

 Lepidodendron Series appears to have been N.N. W. and S.S.E., 

 both in the Eastern and Western areas, but there is no evidence 

 to show when this folding took place, as regards upward limit in 

 geological time, in Victoria. 



In New South Wales, in the Southern portion, the Carboniferous 

 rocks are highly inclined at the Clyde Mountain, but we have not 

 sufficient evidence yet to admit of generalising on the direction of 

 folding. The tilting almost certainly antedated the Permo- 

 Carboniferous Period, as in neighbouring areas the Permo- 

 Carboniferous strata are nearly horizontal.
