THE HEART OF THE ANTARCTIC 



two shadows rising from Mount Lister joined the ordinary- 

 shadow of Erebus cast upon the foot-hills of Lister. 

 There was at that time no suggestion made as to the 

 nature of these shadows, and it was not till later detected 

 that some of them were not straight. 



On September 2 the curious curved " shadow " was 

 first noticed, and was afterwards observed frequently. 



Earth Shadows, September 17 



To illustrate this remarkable " shadow " it is necessary 

 to make a diagram in which perspective is everywhere

 Erebus was almost behind us, and the whole curve could 

 only be seen by turning the head. 



In the picture both mountains are shown, Erebus on 

 the left. Lister on the right. The shadow of Erebus falls 

 up on Lister, and the curved line joins them, broaden- 

 ing out near each end. In the foreground is outlined
