528 A CORRELATION OF CONTOUR, CLIMATE AND COAL, 



acknowledge the continued help and advice I have received from 

 that gentleman. 



Conclusions. 



(1) The Cassilis Geocol exercises a profound influence on the 

 climatological conditions of the State. 



(2) This Geocol arises from the action of the Goulburn River 

 on the south and the Peel River system on the north in shifting 

 the Divide. 



(3) This action having occurred on one and the same geological 

 horizon (i.e., Permo-Carboniferous Coal Measures) — coupled with 

 similar action in the Shoalhaven district — indicates a correlation 

 worthy of note between the Contour, Stratigraphy and Climate of 

 this State. 



(4) The rivers of the western plains of New South Wales seem 

 to furnish a striking example of Ferrel's law of moving bodies as 

 affected by the earth's rotation. 



(5) The use of stereograms should be extended for all purposes 

 of physiographical research. 



EXPLANATION OF PLATES XLV.-XLVIII. 



Plate xlv. 

 Mean annual lines of equal temperature (isotherms) plotted on the Stereo- 

 gram of New South Wales, constituting a Stereo-isothermal Chart. 

 This figure illustrates the bulging over the " Cassilis Geocol " and 

 the hot "hinterland." 



Plate xlvi. 

 Chart showing the connection between the general rain of October, 1905, 

 and the three " land massifs " (rain in points). The position of the 

 Hawkesbury Sandstones (H.S.) and Coal Measures (P. Carbs.) also 

 indicated. 



Plate xlvii. 

 Chart showing connection between land-form and rainfall for 1900 (Stereo- 

 isohyetal Chart). The " negative loop " extending over the Hunter 

 Valley is strongly marked ; and positive loops are shown over the 

 Warrumbungle and Monaro Ranges. 



Plate xlviii. 

 A Stereo-isohyetal Chart for 1902, showing negative loops in the river 

 valleys and over the Cassilis Geocol.
