 valleys nearly a mile in width in the "Newer Volcanics" 

 of Ballarat. 



The canons of the Pleistocene Period are now busily 

 engaged in sawing their ways towards the "leads." In 

 some cases they have accomplished their purpose. From 

 a study of the basalts covering these leads it appears almost 

 certain that some of the great lava floods of New England 

 belong to the "Newer Volcanic" Period. 2 These are now 

 much dismantled. Broad valley surfaees have been formed 

 in them by stream eorrasion, while still later canons some- 

 times as much as 3,000 feet in depth have been formed in
