What means that strange word on that flag

1 What means that strange word on that flag?
It signifies onward and up:
A motto like this will ne'er drag
From any the bright star of hope.

2 O, may every bright girl and boy
This motto adopt for their own;
'Twill yield them on earth peace and joy,
And lead them at last to God's throne.
