1^8 NOTES ON THE GLACIAL BEDS NEAR WYNYARD. 



Twenty years later Mr. R. M. Johnston published 

 his Geology of Tasmania. On page 258 of the standard 

 work on Tasmanian 'Geology, Mr. Johnston gives the 

 following section of the bluff near Sandy Cove, in de- 

 scending order — 



4. Basalt, of palaeogene age. \ 



3. Turritella — group. C Eocene. 



2. Crassatella — bed. ) 

 I. Conglomerate and shale. Silurian. 



Mr. Johnston is of the opinion that the basalt con- 

 glomerate and shale are of silurian age, and that the 

 Turritella group, as well as the Crassatella bed, belong 

 to the Eocene. The age of the basalt is not exactl}^ 

 stated, though it is included in the palaeogene epoch.

Montgomery (i) visited this part of Tasmania about 

 seven years later, and he dwells on the peculiar features 

 of the conglomerate, which he terms " Wynyard forma- 

 tion." He thinks that it forms the base of the permo- 

 carboniferous series, and he agrees with Stephens as to 

 the glacial origin. Waller (2), who writes a few years 

 later, fully corroborates Stephens and Montgomery's 

 views. 



In 1902 Kitson (3) publishes an exhaustive paper on 

 the glacial beds near Wynyard. If I am not very much 

 mistaken he was the first to recognise that numerous 

 "boulders were scratched. Kitson mentions quite a 

 number of dififerent rocks he found in the glacial drift, 

 and from his list it is evident that rocks of the crvs-
