The figures given in the foregoing lists have been graphed as 



shown in fig. 10.

Fig. 10. 

 Graph showing: A, the variations in level of the Blue 

 Lake (in feet) ; B, the annual rainfall of the south- 

 eastern counties of South Australia (in inches); C, the 

 annual rainfall of County Lowan, Victoria (in inches). 

 From 1895 to 1920, inclusive. 



It will be seen that there is no regular relationship, 

 whatever, between the curve of the annual rainfall (which 

 supplies both the ground water and the sub-artesian water of 

 this area), and the curve of the annual variations in lake 

 level. There is, however, a close relationship between the
