 that the amount of water in the ocean was 

 tremendously increased by the melting of the 

 glaciers during their recession. It hardly 

 seems possible that this would account for the 

 difference in level which seems to have taken 

 place during the last thousand years or so, 

 at the same time that an opposite change has 

 been taking place in Labrador. Be that as 

 it may, if one stands at the top of Hog Island 

 at high tide at the full of the moon, and looks
