At firs it grumbles, then it swears, and then,
Like David, fling smooth pebbles 'gainst a giant;
At last it takes to weapons such as men
Snatch when despair makes human hearts less pliant.
Then comes 'the tug of war;'—'t will come again,
I rather doubt; and I would fain say 'fi on 't,'
If I had not perceived that revolution
Alone can save the earth from hell's pollution.
