NEBULA TO MAN 
Sealed up in ice are regions wide and far 330 
By glacier streams that frozen Canada 
Has from her snow-fields sent. Nor yet alone 
About her vasty landscape have they gone. 
Columbia's north, by native ice oppressed, 
Has felt their added weight from east to west. 335 
Twelve states to be beneath thick ice lie hidden, 
Their vales filled up, and mountain heights o'erridden. 
All life that could the power to move command 
Must long have left these scenes of stricken land ; 
And well may Earth, if by her can be known 340 
A strain from weight, beneath her ice-load groan.
