Davis to geographical studies; and his numerous papers embodied 

 in the publications of Harvard College, The American Journal of 

 Science, the Geographical Magazine, the Geological Survey 

 of the United States and other Societies are invaluable to 

 intending workers in this field. The writer also desires to record 

 the great help he has received from the perusal of a paper on 

 " Shoreline Topography" by Dr. F. P. Gulliver* and one of the 

 volumes in the Progressive Science Series on "River Development" 

 by Prof. I. Russell. 



In Australian studies very little attention appears to have been 

 bestowed on the importance of appreciating the relative value of 

 various operations known to occur in a cycle, although in a paper 

 on "The Kaised Beaches of the Hunter River Delta," by Prof. 

 T. W. E David and R. Etheridge, Jun.,t the later elevation is 

 differentiated from the earlier and more important subsidence, and 

 to each is assigned its proper share in the coastal topography. 



Other workers; recognised the operation of contrary move- 

 ments in the northern division of this State in Extra-Barrier 

 Reef areas. A keen observer like Jukes,§ as the result of 

 inductive studies, recognised undoubted signs of elevation along 

 the Queensland and New South Wales coasts, but condemned his 

 own deductions therefrom as premature inferences because 

 apparently discordant with the conclusions arrived at by the 

 great Darwin for the same place from "Barrier Reef" considera- 

 tions. The Rev. J. E. T. Woods] | also disputed the case for 

 elevation, probably on the same grounds. 



Other observers of note, however, like Prof. A. Agassiz, Dana, 

 and Rattray, II untrammelled by prejudice, recognised the validity
