RAIN, WIND AND LIGHTNING. 



The pilled" sections of sandstone bear witness to the storms of ages passed away. A and F show that the rain fell 

 vertically, but in E the marks are deeper on one side than -the other, showing that here the rain fell slantingly, driven by a 

 strong wind. B shows the bore of lightning as it buried itself in the sand and fused the separate grains together, and so formed 

 a lube The cross-section to the left shows the actual channel bored by the lightning. D are the internal guards of a species 

 of cuttlefish, but popular belief has erroneously regarded them as thunderbolts.
