Introduction. 

 With the increasing interest shown by geologists gener- 

 ally in the origin of topographic forms in Australasia, it 

 becomes more and more a necessity to have an accurate 

 model of the continent prepared by means of which to test 

 the value of the various hypotheses put forth to explain 

 the origin of the present topography. Only after a detailed 

 topographic survey has been made will such a model be 

 obtainable. In the meantime it is helpful to have figures 

 which represent somewhat correctly the larger topographic 

 features of the continent. 



To supply this need, various models and maps have from 

 time to time been prepared by Australian geologists. Of 

 these, that of Lake George and the Federal Capital Site by 

 T. Griffith Taylor, of Australia by Professor David and 

 W. K. Mclntyre, of New South Wales by T. Griffith Taylor, 

 of the Warrumbungle Mountains by Dr. H. I. Jensen, of 

 the Adelaide Region by W. N. Benson, and of the Jervis 

 Bay, Upper Shoalhaven and Nepean Region by L. F. Harper, 

 may be mentioned. That by David and Maclntyre illus- 

 trates the broad relations existing between East and West 

 Australia on the one hand, and between Australia and the 

 adjacent oceans, on the other. The models of Harper, 

 Taylor and Benson are fairly accurate representations of 

 the topography of very limited areas of the continent.
