40 NOTES ON THE GEOLOGY OF CRADLE MOUNTAIN DISTRICT, 



no evidence that they extended far to the north, but 

 occupied only the comparatively mature upper portions of 

 a rejuvenated river system, and did not extend beyond 

 the heads of the canyons which then reached to within a 

 few miles of their source. In the gorge of the Fury, 

 which had been cut back almost to its source, no sign of 

 glaciation was observed. 



The writer is indebted to all the members ox the party 

 for ?,ssistance in various ways, especially in raft-building 

 and sounding. Mr. Butler's and Mr. Maxwell's photo- 

 graphs have been most useful in the preparation of the 

 paper. Mr. Butler has provided the amended copy of 

 Malscher's majj, which is the basis for the geological map 

 herewith, and Mr. Twelvctrees has kindly discussed with 

 the writer some of the questions here raised and added items 

 to the Bibliography. To his father, Mr. W. Benson, the 

 writer is indebted for Plate 3 herewith, based on photo- 

 graphs, sketches and descriptions. Plate 4. is from a 

 photograph by Mr. Spurling, of Launceston.
