Doth human progress win the day;

Step after step,—and o'er and o'er,—

Each seeming like the one before,

So that't is only once a while,—

When sudden Genius springs the stile

That marks a section of the plain,

Beyond whose bound fresh fields again

Their widening stretch untrodden sweep,—

The world looks round to see the leap.
